[Q]

I was wondering if there was some sort of video upscaling present when videos of a lower resolution like 720p and 1080p videos are played. I mean, there's not much point in a QHD screen if even 1080p videos are pixelated, right?

What do you mean? They have to be upscaled, how else would you want to watch them? In a small window? 720p should upscale without any quality loss (1 pixel becomes 4 pixels), 1080p should look great too but with a slight, probably not noticable at such small screen size quality loss.

1080p videos look great on my Tab S 8.4 i don't see any reason why they wouldn't on the Note 4.

Sorry. Yeah, I mean lossless upscaling.

Lossless...?
Relative to the 1080p, sure, it's lossless as you don't lose any resolution from 1080p. Relative to 1440p? Well, in that case of course you lose resolution if the source video isn't 1440p.
Sorry, I'm not too sure what you mean by lossless.

Looks like I've been doing a shoddy job of explaining myself. Sorry about that.
I know that this may sound completely retarded, but what I meant to ask was this : Does the Note 4 have the same type of upscaling that is present in 4K televisions?

[Q] 4K output

I've asked Mad Catz but not had a reply. I'm looking for some info before I buy.
The MOJO is meant to be a 4K console, however I'm struggling to find any more info about this, does it do actual 4K or does it do like most cheap Android TV hardware and downscale 4K to 1080P internally before upscaling at 4k?
Can it play 4k HEVC (h.265) at 60fps? (the UHD standard)
Does it have HDMI 2.0?
cheers for any advice.

Hi,
Sorry, I don't have a 4k tv to tell you.
Why would any device (cheap or expensive) downscale from 4k and upscaling it back to 4k? doesn't sound right to me.
Do you mean just upscale 1080P to 4k?
Does it have HDMI 2.0?
I doubt it, as it come out only a month before the mojo's launch date.
But it does support 4k
https://en.wikipedia.org/wiki/HDMI

I know it supports 4k, but that doesn't mean anything, a lot of devices do but all they mean is that they output at 4k (upscale), I need to know if it renders a 4k video at 4k and output it at 4k, if all the mojo can do is output 4k then it plays a 4k video at 1080p as that's all it can handle (downscaling it) then output at 4k, there just seems to be no info and their web page isn't clear at all.

The page is pretty detailed with tech, It's native support at [email protected] fps, 100% no doubt for me.
http://madcatz.com/4k-coming-to-mojo/
They even give visual proof:

"We did some 4K tests at UCSD’s Qualcomm Institute, using their LG 84” 84LM9600.

Above, QI’s Todd Margolis shows Blender’s 4K CGI Demo Video Tears of Steel playing on M.O.J.O. Download it yourself from here and watch it in 4K. It’s free!
We used the MX Player app which supported .mov, .mp4 and more 4K file types. In our tests, we noticed some dropped frames only when bit-rates got higher than about 70Mbits/s."
You can use the controller as a remote, and it doesn't look fake to me, maybe his grin, lol.
I Imagine if a 1080p was upscaled to 4k it wouldn't look as clear as it does in that image (I can't see any pixelation, can you?) .
I doubt MadCatz would go to the trouble of testing it and make a page like that if it was just upscaled from 1080p.
Try asking on amazon, good luck
Edit, or ask Todd yourself: http://toddmargolis.net/about.php
His twitter, etc are at the bottom.

It does not have hdmi 2.0 so you will be limited to 30 fps.

Galaxy S6 4k Video

So in this video I used a tripod which took some amazing video. But I also took 4k video while driving (I was not driving) and the camera did a good job at keeping a still video. There was still a lot of movement but it shows less in the video then there actually was. I captured mainly movement to see how the camera could keep up with it.
You can watch the video here:

True, but the camera is the same so it still goes for the S6 itself. Both phones are equal when it comes to camera.

Do you know if the 4k video was encoded with the native h.265 encoder rather than the older h.264? The exynos soc supports native h.265 encode / decode which should help with 4k video size.

Here is a utility that can show you details about your media file. Just point it to the raw video file that was generated by the s6. By the time it gets uploaded to youtube, it is transcoded so no way to tell the native encode format prior to the conversion on youtube.
One of the strong features of the new chips, including the 810 are it's ability to natively encode and decode h.265. This is remarkable as even intel chips cannot completely hw encode+decode the new format. The newer nvidia/amd cards are making progress towards h.265. So I hope you can appreciate that little device in your hands can do this. But whether it actually does and makes use of it is the question. I hope you indulge us.

The quality of the focus is amazing.

Z5 Premium not really a 4k phone

Why is it that no one has reported that the 4k resolution on the Z5 premium is only 4k when playing or filming 4k video. At all other times i.e 99% of the time, the device has normal resolution. I think its misleading by Sony regarding the way they have advertised the product. If I buy a 4k phone as Sony has described the Z5 premium, I am more interested in my home screen, normal apps and text messages etc being 4k resolution rather that the ability to film 4k video. Its not that I need such resolution for these but merely the principle.

So you'd rather have a battery that will last you for half the day? Because there's no way around it that the Premium is the first 4K phone, and Sony really played it smart where it won't be a flop by adding smart software that enables 4K when it's needed.

No I'd rather Sony did not push the Z5 as a 4k phone when it isn't. I would have bought it for the screen size alone. The BS about it being a native 4k screen is poor customer service. If battery will be an issue they should have put a bigger battery in. it's thick enough.
What I am also puzzled about are all these journalists with their previews and hands on reviews stating how the screen is great or that they can't tell the difference from a normal phone. Did these chumps not know that's because it isn't a 4k screen most of the time.

They did put 4k resolution hardware they just did not used due to fact that it is little difference or make no difference on 2k. Their might be possible to to change resolution if you root and develop ui.

That's really no different than a 4k TV.
Unless you're watching specific 4k content on your TV, you are looking at 1080p/720p resolution. User interfaces on 4k TVs generally aren't 4k because there is no point. That dosen't make the screen NOT 4k, or the Z5P's screen NOT 4k. It's just that you have to be watching 4k content to actually see it at the proper resolution. That's how all 4k devices are, and they are all advertised as 4k, and rightfully so.
I mean I don't know what you expect... you want the browser/texting to be 4k? What's the point of UHD aside from watching videos? None of the websites you visit will be in 4k aside from when you're watching videos. Sony did the right thing here in utilizing the 4k screen for videos/pictures. There would be no point in having a 4k home screen since it would just drain a ton of battery

Are the journalists reading this site or is it a coincidence that articles about the lack of 4k on the Z5 premium now start to roll out a few days after my post. Am surprised this was not reported on day 1.

interesting

Your point is absolutely no-point. The phone is 4K phone because it has native 4K display. That the UI (applications etc.) are not native 4K is just because there is absolutely no point rendering user interface at 4K. The point is that th phone is capable of natively displaying 4K content. User Interface is not 4K content and there is a good reason behind it.

How about this article? Does it help?
http://www.gsmarena.com/sony_xperia_z5_premium_4k_display_under_our_microscope-blog-13887.php

My point is that 4k TV/video is not here yet. There is no content. So the 4k video feature is pointless. I don't give a monkeys about the ability to record or view 4k video.
However what a 4k screen provides is better overall picture quality. Whilst the improved ppi will not be noticeable, 4k produces better colours and brightness. This is the feature of the 4k screen that I would be interested in. At the end of the day the Z5 premium is no better than my current Z3. It definitely looks uglier than the Z3.

Funny thing is, Nobody ever complained when their phone's CPU are running on 600mhz on idle when the spec sheet is 2.3Ghz. smh

You want the phone to run at 2.3GHz when it's idle. Why?

Seems you don't get my /s implicitly there.. :/ the 4K situation looks a lot like CPU speed. It can be pushed to max but it doesn't have to be activated all the time. But here we are, people are complaining for such reserve as a drawback.

Because the OP wants 4k to run all the time.... He isn't thinking the clever mind who thought of 4k for videos and pictures only.....
I suppose he also wants the CPU to run at 2.1ghz all the time ... And the ram.... It's stated 4gig but available would be around 3.8gig.... Let's crib for that as well

Uhh what? There absolutely is 4k content. In fact, I'm watching Breaking Bad in 4k on Netflix as we speak. Lots of major streaming services are getting 4k content and there is more and more every day.
Are you upset that TV manufacturers are advertising TV's as 4K even though most content watched will currently be 1080p/720p? The TV UI's are generally not 4K. How is that different?
And just like TV's, Sony has claimed that the phone will upscale 1080p content, so it should produce better color and brightness, although who knows how noticeable it will be w/ such a small screen?

We always can see whether the panel is 4K by playing a 4K video from youtube. Like it should give the option to switch between the qualities, Am I not right?

Read this, son. It will play 4K and will UPSCALE image/video content to 4K, along with the other image/video enhancements. That's the focus of the phone, a "premium" viewing experience. The UI will remain 1080p to preserve battery life, because who the hell cares about the image quality of the freakin' UI? Same goes for apps and games, unless (maybe) the game actually comes with 4K resolution, which I doubt there are for now when consoles still struggle with 1080p.

It indeed 4K panel. only uses for Media and stuff.

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!

Is that not what I'm already doing.....?

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.
