HDMI out resolution

Hello,
Has anyone tried using the HDMI feature? I just received my cable yesterday and was able to view anything in my gallery and youtube. The only thing that bothered me is that everything was output in 480p. (I had youtube set to HQ and it made no difference)
Does anyone know if the phone can output at a higher resolution?

it's supposed to be possible to output 1080p, thats what all the specs i have seen for the phone say

Thats what I thought. I was unable to get anything higher that 480p though. My tv is 1080p 120hz.

hmmm... well i wish i could help ya man, i dont have a cable yet
but hopefully someone smarter than I that has a cable will be able to figure this out

I doubt youtube even HQ is streaming in 1080p
EDIT: In fact, it'd be my guess the max output resolution is probly 720p (considering it can capture in 720p)

his gallery should be higher rez though. i doubt thsi phone has the power to play 720p compressed.

The max resolution on the camera's video capture is 1280x720, which is 720p. So I doubt the phone will output anything higher (like 1080p/i). In fact, I saw one reviewer that stated that he "thought" the phone *only* outputs 720p, upconverting any video to that resolution. But I don't think that has been verified. What I *can* verify is that video shot with the camera at 720p and shown on an HDTV shows EXTREME compression artifacts to the point that a lower resolution will probably give better results (although you will not get the 16:9 aspect ratio).

What about regular HD movies in 1080p/i that are saved onto your sd card. How did those do on your hdtv. Did they come out choppy or compressed at all? I'm waiting to get my hdmi cable to test it out myself.

Actually the specs never say 1080p, they say 720p. And from what i've seen that's only when outputting pics and videos form the gallery player.

We want to get netflix on our Evos and do the output to our TV's.
I wonder how the outout will look on that?

I have seen it somewhere listed... ill attempt to find it and post back

I remember seeing a post on engadget a couple weeks back with a video demoing the ability to play youtube hq through HDMI. they were watching a video that had paint splashing around in slow motion. It looked great! Last night I tried to watch a couple of youtube videos that were hq quality with the hdmi cable plugged into my tv and they looked horrible. I thought it might be a setting on the phone, but I could not find one.

I have the same problem with youtube. It seems that it does not use 720p, even in "HD", it seems the "HD" is actually 480p (the EVO screen resolution). Another problem with youtube on EVO (as opposed to TP2) is that unless you click "HD" there is no way to stretch the video to full screen, even when viewed on the EVO screen. This is one of the most unfortunate things I've found when trying to impress my iPhone loving friends. On the TP2, youtube was surprisingly excellent, it filled the entire screen and looked fantastic (without an "HD" option) the EVO seems to have actually taken a step back (albeit a small step) in that department.
While using the HDMI cable to my TV, it will output 720p videos (taken with the phone camera or made with handbreak.) However, it will not scale anything up. So if you create a video at the 800x480 EVO screen resolution, it will display in the center of your TV (not fill the entire screen.) I've not yet tried 1080p, considering the 1600mbs (realistic) encoding limitation, I don't think 1080p will be a good idea even if it does work, just stick with 720p.

So 720P movies and stuff will work just fine?

Can it display the UI of the device and other apps...or only multimedia content?

Think it is possible to could be done via software?

This x 1,000.
I'm still not sure if I'm getting an EVO or Streak, but both have HDMI, and either way, I want to be able to hook my device up to a monitor and use it in the same fashion that I would my netbook (i.e. light web browsing, very light office/doc work, maybe some light games).
Basically, I'm looking to get rid of my netbook and replace it with my new smartphone...but I have to break out to a larger display from time to time.

Tegra 2 missing NEON video decoding instructions - any solution to be expected?

the Iconia tablet (stock rom 3.2) has a most troubling issue: no (or no smooth) video playback of HD video files, mostly H.264 encoded mkv and mp4 files. Acer and Nvidia claim the device can run 720p and even 1080p in h264 base profile but the bitter reality is that even 90% of 720p video files don't play smoothy due to lack of proper hardware acceleration. this is really a huge disappointment as even most of today's discount phones can play 720p video and i got me a dual core device with a HD screen and a GPU from a dedicated graphics expert company but have to stick to SD video.
i found a statement in the Nvidia developer forum saying that Nvidia is working on this problem with some software partners which indicates that there might be a software solution to this sometime soon:
http://forums.developer.nvidia.com/...6/is-tegra-2-support-neon-intsruction-set-/p1
my question: is a software solution realistic or maybe just a waste of time? personally i doubt it, especially since the successor, Tegra 3, again includes NEON.
but maybe a custom rom like Thor could add enough horsepower to the device to enable at least smooth software decoding? anyone using this rom already noticed a performance gain?
i am looking forward to your comments.

you think i would investigate in hardware related stuff and post here if there was a player that could handle all HD video? MX player clearly does not, nor does any other player (dice, mobo, rock, just to name a few of the better ones) handle high profile H.264 video on Tegra 2 devices. so 90% of the stuff available online is not working, means they wont play at all or have massive framerate and sound issues. go and check out the latest movie trailers available in 1080p mp4 or download an x.264 encoded mkv file of your favourite tv show and you can see for yourself.
if you insist on your statement, then please put up a video source so i can verify. i would really love to learn that you are right and i have just a broken device ;-)

Well if you're trying to play 1080p video on a device that only has a native resolution of 1280 x 800 as this statement indicates, then the joke is on you sir.

also, i don't get your point about the resolution. are you trying to say that a full HD display is mandatory in order to enjoy a 1080p video? or that its content will look better if video resolution would match the Iconia display resolution? sorry sir, i really think you are the funny guy here.

there might be cases where a hard- or software scaler messes up while downscaling a video and picture quality degrades, but generally the higher the resolution the better the picture quality, regardless of display resolution.

Atleast I can play baseline and normal profile H.264 content at 1080p just fine. It's only high-profile that reverts to software and doesn't play well.

The display itself is 720p, so trying to play 1080p content on a 720p display is kind of pointless. You won't see the extra resolution anyways. Though if you're playing through HDMI to a 1080p display then it makes sense.

Not entirely correct. Higher resolution doesn't equal better compression quality, so you can easily have 1080p video that looks like ass crap, and you can have SD video that looks better.
That said there are lots of reasons to choose 720p over 1080p on A500: 720p high-profile video generally looks much better than 1080p baseline-profile, high-profile fares a lot better in high-motion scenes, and high-profile takes less storage space than baseline-profile. And well, since you can't see the extra resolution anyways you're just wasting extra storage space on stuff you can't even see.

A software solution will only boost applications that are specifically designed to utilize it, and the hardware simply isn't fast enough to decode 1080p high-profile in software at full speed, so no, no matter what NVIDIA is claiming they cannot do magic tricks here.

Thor or some other custom ROM can only increase clock speed, there is nothing else to be done about it. And you can increase clock speed even on the stock ROM anyways.
But as I mentioned I have absolutely no problem running 1080p baseline- or normal-profile content, or 720p content, because I am not using the stock player. Use one of the players from Android Market, they're a lot faster and smarter than the stock player.
Also an important note to you: the stock player reverts to SOFTWARE if audio is AC3 encoded. That is probably the issue you're seeing. The players from Android Market do AC3 in software, but send the video to the hardware, so that's why they don't lag with AC3 audio.

I was on topic, if you can't understand that attempting to play 1080p Res videos on a 1280x800 display has no benefits whatsoever, then maybe you need one of These.
I honestly don't understand what is so friggin' tough about understanding the concept, and you clearly stated 1080p in your first post.

He's trying to playback through the HDMI port, muppet.

Here ya go, educate yourself.
" If the incoming source has more pixels than the display's native resolution, you will lose some visible detail and sharpness, though often what you're left with still looks great. If the incoming source has fewer pixels than the native resolution, you're not getting any extra sharpness from the television's pixels."
http://reviews.cnet.com/hdtv-resolution/

guys, and ladies, please, this thread is not about pro and contra of full hd content on smaller displays.
the question is:
is it likely that (at some point soon) there will be a workaround to overcome the issue of the missing NEON video instruction set on Tegra 2?
again, my goal is not to play 1080p content on my Iconia, just some 720p stuff, mostly TV shows encoded in H264 high profile mkv files. and no, they wont run using MX player or any other player currently available. and i guess that's also due to the missing NEON. please see the link provided in my first post.

thanks. well, in respect to 1080p content i don't have much hope either. but, and again, 720p content encoded in h264 high profile does NOT work for me. i have massive framerate issues and sound also drops off completely after a few seconds. i tested with google, rockplayer and mx player (all of the latest builds).

You sir are an ignorant boor who is incapable of reading. You couldn't read the posts properly and you can't even read your quote properly.
A 1080p file has more visual information. For example, it's possible to see a small mole on somebodies face in 1080p that in 720p or lower has been smoothed out and is now invisible. Playing that 1080p file on a lower resolution device gives the possibility that the mole will be visible depending on how the hardware scaling is done and since most hardware scaling isn't going for compressed file size and won't be applying gaussian blurs etc... you WILL see that mole.
The new Nook Tablet and Kindle Fire have the same screen resolution, one streams videos at SD and the other at HD. Now even though the tablet isn't capable of HD the one that streams HD is noticably sharper and has more detail. Go look up the pictures if you want. Take your own advice and educate yourself before you berate people for their ignorance when it is you who are ignorant with poor reading comprehension.

Mate, it doesn't work like that. It doesn't matter if the picture is scaled down before compression or after decompression, it's still scaled down. And no sane compression technology uses gaussian blur.

The difference is due to the fact that the HD video is compressed with better quality settings than the SD video. Besides, Kindle Fire IS 1024x600 pixels in size which means it is indeed almost 720p HD resolution meaning that HD content only needs to be scaled down by 120 lines whereas SD content has to be scaled UP instead: well, OF COURSE it will look like crap.
In other words you're comparing apples and oranges and you don't know what you're talking about either.

I just tried that file with Dice Player. It stutters for about 5 seconds, then settles down and works like a dream. In other words, working just fine on my tablet.

I had problems playing 720p mkv files as well, no matter which player I used. The stock 3.2 rom appears to be missing the framework for hardware decoding of these files. No such problems since installing various Thor roms though. They all play fine now. 1080p is probably too much though. I use mx player by the way.

[VIDEO] HDMI Output from the Amazon Kindle Fire HD 7" Tablet

I demonstrate the HDMI output capabilities of the Amazon Kindle Fire HD 7" Tablet. I am very impressed with this feature.
PLEASE NOTE: This video does not do the output justice. Trust me, the color is very accurate and the contrast and saturation are very close to what you see on the tablet's screen. Unfortunately, this video shows the TV as being a little blown out. This is not the case in real life.
Stay tuned for even more videos soon!

I'm getting more and more convinced to buy one, keep the vids coming :]

If the video on the KFHD is only 720p is it outputting 720p or 1080p to the TV?
Do you know if Amazon instant video support 1080p output via KFHD?
Thank you. I'm wondering abouf upgrade from KF to KFHD and 720p v 1080p output would make the difference.

Hello?
If the KFHD renders at 720p how does it output at 1080p?
Does the processor process at 1080p and downsize to the 720p KFHD or are there two seperate renderings one for tablet and one for HDMI?

I'm not sure how to determine what the output is. It looks fantastic to me, but I can't give you specifics on whether it is 720p or 1080p. I'll do some further research.

>If the KFHD renders at 720p how does it output at 1080p?
HDMI output is [email protected] That's what the TV said about the input feed in OP's video.
UI display is undoubtedly upscaled from KFHD's 1280x800 (some top/bottom slice is likely cut off). Video render is likely native 1080p. It's easy to tell: Freeze-frame at a detailed frame and peruse the detail. Compare it to native 1080p playback on your PC. You should be able to see the diff if it's scaled-up 720p--and if you can't, then it's a moot point anyway.
Edit: On second thought, if the video is shown on both KF and TV displays, then it's probably scaled up 720p. To do native 1080p on TV, the KF would need to render two different res simultaneously, which may still be within the 4460's capability, but isn't the most expedient route.
Edit2: From looking at OP's vid again, it looks like KF preserves the entire UI display on HDMI out. So instead of lopping off the extra 80pix and losing part of the status/menu bars, it squishes the 16:10 AR down to TV's 16:9, which is preferable, as you can't normally tell the difference anyway.

Sounds about right. There is a TINY delay in the TV, so it's possible that is stemming from an independent render from the actual tablet's display. Either way, it sure looked good.

That is what I stated e.mote.
A video was played that was supposedly 1080p. Now the KFHD has to downscale the video to 720p since the resolution of 720p is 1280x720. The KFHD is 1280x800 so it will fit the screen with 80 extra vertical pixels.
1. Either the KFHD is sending the 1080p video output to HDMI before it downscales the resolution
2. The KFHD sends the downscaled resolution to HDMI
3. It has a seperate rendering for both outputs.
reverendkjr: If you could take two pictures of the KDHF playing a video in both 720p and 1080p and compare them we could more easily arrive at a solution.
Thank you.

I don't think that a picture is going to help here. I watched a 720p and a 1080p trailer on the device. They look identical. I could not see any difference at all. I also looked at the TV playing both. There was a definite difference. The 1080p was indeed a lot higher quality.
My conclusion:
On the device, it scales. So it can only play whatever resolution the device can handle. In this case, 1280x800.
The HDMI must have it's own render, because I believe it was definitely playing 1080p on the TV.

>If you could take two pictures of the KDHF playing a video in both 720p and 1080p
You can't take a snapshot of HDMI out. The reason content vendors selected HDMI is that it's a secure path which prevent signals from being captured (read: pirated). There are HDMI recorders, but AFAIK they do analog captures, which means a fidelity loss.
The only sure way to tell is from the eyeball test, which needs to be done firsthand. If you're that worried about it, go to a BestBuy and ask to have the demo model plugged into a TV display, then run a 1080p clip and do the eyeball test yourself.

I apologize if my request was not sufficiently clear. What I meant was a picture of the TV via HDMI out of the KFHD with a lens that captures images with a sufficiently high resolution.
For now, as it is apparent you have, by your testimony, tested via direct visual experience, I will grant that you are correct and that the output of 1080p video is of significantly higher quality compared to that of 720p.
Thank you reverendkjr.

Well I have a cheap router and only a small cable modem from Verizon and I can get Netflix to play what I'd call more than acceptable on the KFHD. However, going to the TV from there, the picture is not even close.
If it was bad on the KFHD I can understand. Does something have to be enabled or maybe it is the cheap cable I picked up from Best Buy that I use with my Acer A500? It works at least so I thought it would be compatible with the KFHD but maybe not good enough.

You have to check your bandwidth. Since you're on your KFHD it might be difficult.
Netflix 720p requires about 5mbps. You can Google bandwidth test from a PC to check your download speed. If it's less than 5mbps your video won't be 720p.
http://en.wikipedia.org/wiki/High-definition_video#World_Wide_Web_HD_resolutions
It looks like Amazon instant is only 720p. Netflix only supports 1080p on certain devices. So much for 1080p.

Cable modem and router to my KFHD I understand about bandwidth and the PQ is very good, BUT I I'm unaware of bandwidth being an issue from KFHD to TV unless I'm mistaken.
I need to read other experiences with this feature and how good or not it is. Something tells me it isn't the cable I'm using either from KFHD to TV.

Well KFHD has less than half the pixels of a 1080p TV and the pixels are much more dense in terms of ppi(pixels per inch). When you view the video on your KFHD through netflix and the stream is less than 720p due to bandwidth constrictions, it is entirely likely that the picture will look fine on your KFHD but inadequate on a larger TV with a much lower pixel density.
If your bandwith is less than 5mbps you won't be viewing HD video through Netflix, it will be SD (standard definition) which won't look good on a HDTV.

Thanks for the clarification.
I have a Blu Ray player I stream movies from to the TV which is pretty good so not having a great picture from the KFHD to TV isn't the end of the world to me. I don't stream that much really, I just flip in a Blu Ray disc for PQ nirvana.

I picked up a cheap HDMI to HDMI micro cable at Best Buy to test the HDMI out on the Kindle Fire HD (Rockfish)
I tested the HDMI output playing a couple of HD movies from Amazon Prime (True Grit and Into the Wild). Both of these movies look fantastic on the Kindle Fire HD. However, when viewing on the my HDTV's, the quality of the video is not that good. For example: It's not nearly as sharp as an HD program via Direct TV for example. The picture is kind of washed out and not very clear. It looks a lot like SD instead of HD.
I also noticed that the audio is not being output as Dolby Digital 5.1. I was hoping that it was.Has anyone had any luck Dolby 5.1 sound output?
Note: I tried it on 2 TV's (One 50 inch Samsung 1080P Plasma and also on a 37 inch Panasonic 720P Plasma). Similar results on both. Maybe it's the cheap "Rockfish" cable I picked up at Best Buy to test with? Maybe I'm missing a setting somewhere? I was hoping for typical HD quality picture when using the HDMI out. But, I'm not seeing it on my TV's at least. btw....I have charter cable internet (50mbs download speed)....so plenty of speed.

I tried outputting to a smaller Sony HDTV display, 32" instead of my Samsung 40". While better, movies isn't something with my current router and cable modem I will be doing from the KFHD.
I have an Acer A500 which has HDMI interface as well. Maybe I'll try it again as I cannot recall if the pq was any better.
As far as the HDMI cable? I'm still unsure if a higher quality one would make any difference whatsoever given my router and cable modem bandwidth to begin with.
There's always games though. Riptide is lots of fun so a plus for that to my HDTV displays!

Thanks for the feedback on the HDTV test. I was really hoping for some better performance for Amazon Instant "HD" video when using HDMI to output to my 50 inch 1080P Plasma. However, based on my testing, the HDMI out on the Kindle Fire HD is something I would never use. At least not for watching Amazon instant "HD" video. I was hoping for something along the lines of what I see when I steam a movie using the Apple TV (really good "HD" picture quality). Still the Amazon instant "HD" video looks great on the Kindle Fire itself & at $199 it's quite the deal. Just wish I had an option to see "quality" Amazon content on my HDTV's (ie without purchasing another device like Roku).

TRUE 4k virtual cinema VR with Z5P incoming

i was SO frustrated looking at similar threads here and around the web so i got in touch with CMOAR virtual cinema and asked them if its rendering 4k or just upscaling from 1080p.
It seems like it's just upscaled BUT since in the past they talked about the chance to have it run at TRUE 4k...they answered me and said:
we have prepared special build with 4k support (Rendering in 4k), fps are of course low but I think we will prepare build for public, because we know that many people just like us want to test it
Please send us a reminder at the end of the month
So get ready. We will FINALLY be able to see TRUE 4k. Maybe at 15fps..but that will be the best chance we had so far..in VR. I think there could be the chance to play a movie in the void theater at good fps.
but the main question i have left is...why didn't you do the same months ago?! I would have done it instantly if i had the phone!

if im not mistaken you posted this and showed that 1080p or 4k things got smaller but readability was exactly the same (reading the smallest line). Am i wrong? In that case, that's not true 4k
other than that i couldn't find in this whole forum a true list of true 4k applications. It's like looking for gold!!

Don't know what you're referring to. If you look at the resolution, it is 4k. When you watch a movie in VR, your virtual void screen is not going to be 4k, it's going to be far less. When my phone is in 4k, the virtual screen resolution is a couple hundred pixels bigger than when at 2k or 1080p.
If it renders in 4k, it's not really going to matter because you're not getting anywhere close to that in void cinema anyways? You're getting about VGA worth of a virtual screen. I think the most important factor with 4k for VR is less screen door effect, not the resolution? Then again, I just started messing with this so I'm not too knowledgeable.

i don't think it works like that..
in virtual cinema now you just have a 1080p resolution upscaled to 4k. SDE has nothing to do with the output resolution and it's going to be the same even outputting at 480p the whole screen.
Even so, putting true 4k in virtual cinema will mean having twice the detail there is now since every pixel will have a "true" color instead of a fake one (with upscaling). That will result in a greater resolution overall.
The only way to really test this out, is with their true 4k output cinema version. Now we're 95% just fooled with upscaling (and as they said 4k will have very low fps)

If I'm not running AAA VR Cinema in 4K, then can you explain why my virtual cinema has a greater resolution then when running the phone at 2k or 1080p? Are you really going to notice that much more detail if you cram a 4k video into a VGA space or a 1080p one into that same space?

i guess the only way to find out would be 3 screenshots, one at each resolution from a 1080p source clip. 4k is twice as sharp as 1080p, for the same portion of screen. That means that something barely readable 1080p will be twice as sharp in 4k. The void size must be the same and 4k would actually display 2x times a 1080p image, not just 200px more

look, you posted these:
https://postimg.cc/image/nrqysn3y3/
https://postimg.cc/image/z5di3uegr/
the second is slightly higher resolution but the output is the same, resizing back the 4k to 1440p you have the same exact image...that's 100% upscaled, no true 4k happening at all, you would see a big difference going up (1440p is nowhere close 4k, it's jus 125% more than 1080p where 4k is 200% 1080p)

Dude, the function of that app is only to tell you the resolution of the virtual screen. What's within it is for reference purposes. It's not going to change.

$ Bounty $ for native 2K and 4K

I'm creating a bounty for enabling native 2K or preferably 4K.
The resolution/dpi emulation still does nothing more than resize the xxhdpi resources (not even the xxxhdpi), so it still isn't as good quality as 2K displays on other phones.
Moreover, VR (the only real purpose for a 4K phone) is terrible. True, the screen door effect is gone, but at the cost of blurry less defined images same as a 1080p phone. Only Youtube and finally Netflix are able to use the 4K but other apps and games are unable to use the higher 2K resources and downloaded VR movies are fuzzy. Completely disappointing compared to my 2K phone. Also, with the emulated 2K or 4K, Daydream becomes tiny in the bottom center of the screen.
I believe the kernel controls the screen properties, but not sure if there was something to do with it in the ROM for this phone. While I'm sure I could figure it out with all of the easy handy guides, I don't really have time to do the research on how to do it myself. So, I'm creating this bounty.
I'll start with committing $50 to the person who releases the first stable one, but still donate to a second placer
If anyone else would like to sweeten this pot please post how much you would contribute.

I think it's a problem of native 4k apps, not the phone.
You can put it in 2,4k using adb commands, search here https://forum.xda-developers.com/xz-premium/themes/mod-change-default-resolution-to-4k-root-t3618843, but you need apps for that. I have Bobo VR Z5 and it's working perfect in 4k and in 1080p, but only without screen protector.

The adb command is just emulating 4K with the lower resolution resources as said in my top post.
This is how Daydream looks in emulated 4K https://drive.google.com/open?id=1i531VadSbzzu1Or1CMMvBYez5VFi_Mkp
I'm sure without the screen door effect you may feel you're getting 4K VR, but it actually 1080p.
For example, I take 4K 360° photos. the text on distant signs is readable on my 2K phone, but not on this XZP.

Awesome! Hoping this will attract devs to look into this.

It's pretty sharp. It's better in emulated 2k/4k, but good enough for 1080p. At least for me.
Also just to add, I noticed that if you use GMD Gesture Control and calibrate the screen, you'll see that the app reads the screen as 4k. (Even when on stock wm size)

$50 is laughable

That app probably reads the pixel size rather than the set resolution. AIDA64 also reads as 4K the first time, but later shows 1080x1920 or whatever emulated size you set.
When doing the Daydream fix, it also changes the screen from LCD to AMOLED.

true that but even when on emulated 4k you get just as good display as 1080p, its still even not as crisp as other 1080p but cant tell difference, still with emulated 4k just to look at "enhanced" 1080p sucks!
plus you lose more battery than native 2k phones! i bought the phone because of its screen and I cant enjoy 4k at all times, or at least in the UI or any other app that I want in 4k....
im disappointed i really wish there is a fix to get native 4k...
I AM willing to throw in a 50$ as well if some one fixed this (as long as there is a root with TA backup (just in case the fix needs root to modify the kernel- I dont wanna lose DRM functions)

Excellent, and totally agree!
Now the bounty is up to $100.
Let's get more people. We can't be the only ones disappointed that Sony sold us a 4K phone *only in 2-3 apps that is actually locked at 1080p.

Could it be possible to just make other apps 4k by heavily editing them? Like the VR apps. If doing it system wide is too difficult then maybe editing apps might be easier.
I'm curious anyway, who can actually tell the difference between 1080p and 4k on this phone? You say 1080p looks better on other phones, so does the 4k look just as sharp as that 1080p? Also, how do we know Sony isn't just using the emulated 4k when it gets enabled? Not every photo in the album is 4k so how would it enable?
I did take a 1080p photo and a 4k photo and noticed a difference but I wasn't convinced. It didn't seem like a huge difference like it does against a TV/monitor at 4k. Especially on YouTube I cannot see the difference majorly when going from 1080p to 4k but can others? If 4k is difficult to make happen then maybe we could push 120hz at 1080p since it was said that the X series of devices have 120hz displays it's just disabled for some reason. The page needs translating but it shows 1080p at 120hz as an option. This was mentioned in a previous thread but I don't think anyone was interested in it. I think that this has a higher chance since this image exists.
Thats my thoughts about 4k on this device anyway. I think at this point 120hz might be a better option but that's just my opinion. 4k is great but it's only limited at the moment.
https://gazyekichi.com/2017/07/26/画面さくさく！「xperia-xz-premium」は「120hz」に対応している/

here is the thing, true that its very hard to tell the difference between 1080p and 4k on such small screen, so I took screenshots of before and after 4k mod and placed them together on my 24 inch monitor side by side and still can barely tell the difference even on huge screen which proves that its not 4 times better quality so its really fake 4k!! only time i can realize the difference is when i zoom in on both pictures and see that some details are washed out and more "pixel" looking at 1080p while on 4k mod still manages to show more details but then again, such difference in sharpness and detail shouldnt be so hard to notice since on my monitor I can easilyyy tell a difference between 1080p and 4k gaming on my VSR (virtual supper resolution) even virtually on my screen modded 4k has a lot more difference that stock 1080p
while even modded 4k on this device can barely show a difference, so might as well change that in a native way I really cant wait for a fix
PS: running 1080p on 1080p screen looks better than running 1080p on 4K screen (if screens are same size) - proven.
so down scaling the 4K screen of this device to 1080 will make it look worse than other native 1080p screen which buggs me, the least they could have done is add an option like samsung did to just adjust the quality as you wish... I hope they add that in the next update

Yes I agree 1080p on a 4k screen does look worse. On most TVs it doesn't but on my Acer predator 28" 4k monitor it is very noticeable that 1080p looks like 720p when duplicating the screen next to my 1080p monitor. The desktop does look noticeably blurrier. However, 1080p content on the 4k monitor doesn't show a huge difference so I'm not sure what that's about only playing games and the desktop look bad at 1080p. Maybe the XZ1 could have been a better option but even still know that I have the second 4k mobile device on the planet and the only 4k HDR device is still cool. It's certified to be 4k so it can't possibly be a fake 4k it has to be really 4k else Sony would be lying and with all those TV experts I don't think it wouldn't be possible for them to do real 4k on a smartphone.

The screen using the emulated 4k is razor sharp. By far sharper than any other phone I've used including the note 8. Are you sure your not just mistaking the overly unrealistic saturation of a amoled screen compared to a LCD one? I dont mean that in a sarcastic way, i genuinely dont see any comparison between the two. I havnt used the phone for any VR stuff though so can't comment on that

you are right but im not comparing only with samsung, also with HTC and the previous version of xperia , the Z3
yes maybe on emulated 4k it has sharper screen but keep in mind that on 1080 is not as sharp as other 1080p, even on 2k it isnt only on 4k mode it is unbeatable which to add is emulated and not native
put phone on 2k battery dies so much faster than lets say samsung or HTC which both have same CPU GPU and almost same battery size, how is that? because the resolution is emulated, which forces GPU to resize source resolution of 1080p to make it in a fake way look like 4k instead of showing native 4k (which doesnt require such hard work from GPU as its showing real pixels instead of emulating fake pixels!) Which leads to less over heating and less battery consumption.
heck even on 1080p screen looks worse and still get worse battery life than other phones...
thats what bothers

not exactly but some other phones have better 1080p than the 1080p on this device, yes text and symbols maybe just as sharp its hard to tell but im talking about pictures (for example, in instagram, facebook. youtube thumbnails etc...) I once was on 4k mode and it was very hard to tell the difference between this phone and the Z3 and even some times the z3 showed more picture details in instagram and its only 1080p...
im not complaining about the screen though, its pretty decent and with 4k mod on it looks superb, im just saying sony has put some thing in a device that is useless and im trying to figure out why...
by useless i mean sony left us no option to use such settings, why dont they add the options of 1080-120hz or 4k? naive and not emulated! this bugs me
and yes it is 4k, just like youtube you dont have to watch on 4k settings, but you can see the option is there which means it supports it.
that means even if you dont have a 4k video in your video app or album app, the option is there that means if you ever have a 4k video on there the device will play it at its maximum resolution.
phones that dont support 4k will show that the video looks as sharp as 1080 instead of real 4k
