[Q] [B8080-F] Yoga 10 HD+ and Miracast - Thinkpad Tablet General

Hello dear people,
I am pretty new to the Android world and have had my Yoga for three months now. I bought a Media Player (WD TV) for my TV and now I am trying to work out Miracast.
While I do get a connection, my main problem is the aspect ratio. I have a 1080p TV, however, the Yoga 10 HD+ has a vertical resolution of 1200, not 1080. This leads to the image being cropped and the aspect ratio seems slightly wrong (of course, since it's not 16:9 anymore).
Has anybody else had this problem? Can I switch my tablet to a 1080p resolution somehow, or at least the stream? Thank you for your help!
Update: I used the NOMone Resolution Changer, setting the resolution to 1920x1080 with 233dpi, which seems to work. I am currently trying to figure out a way to increase image quality. It's okay, but not exactly what you expect from HD. Also, scenes with a lot of swift movement in them seem to be producing artifacts a lot. Not what I expected from the highly praised Miracast, but it might just be a device specific issue. I will write more when I've done some more research.

[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.

:crying:
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).

Anyone using MHL-HDMI? Wrong aspect ratio?

Anyone using their Tablet Z2 with an MHL-adapter for HDMI input to TV?
I have a Tablet Z which I connect to my TV, and with Android 4.1 stock ROM it scaled the output correctly from 1920x1200 to 1920x1080. But since 4.2 it compresses the picture a bit, making things wider then they should be. I guess it just compresses the 1200 px to 1080 px without keeping the correct aspect ratio.
How does the Z2 handle this? Is there any option for scaling or aspect ratio in the menus?
Thanks,
Daniel
Save yourself from the hassle and don't use MHL at all.
MHL is not needed if one doesn't NEED the screen mirroring (for example if one wants to do presentations with showing spreadsheets etc.).
Sounds as if you just want to watch videos or photos on your TV.
Get a Chromecast, a Raspberry Pi, an Amazon TV, another XBMC-capable device or something like that. And send your media to your TV via DLNA / XBMC. That's the hassle-free way to go.
Why not simply answer his question?
The Z2 tablet outputs 1920x1080 signal through MHL, but as the tablet has 1920x1200 pixels and 16:10 aspect ratio, it puts small black borders on left and right sides of the image on TV. So, you get correct aspect ratio (16:10) in a 16:9 TV. No stretched pictures, but small black borders.
Simple, huh?
You also didn't answer his question. Duh!!
Thank you both for your answers,
I also have a Chromecast, which I use for Youtube etc. but since it only does 720p and have it's bugs, there are situations I would like to use the Tablet Z. It's also convenient to just load it up with movies and TV-series and bring it with me to my friends, everyone have a HDMI-capable TV and there is no hussle with Wifi, formats thats not compatible etc.
RoberM, that was just the information I needed! The Tablet Z worked just like that with stock 4.1 (tiny black borders and correct aspect ratio) but since the update to 4.2 it fills the screen making the image wider then it should be. Even on the latest 4.4.4 the problem exists. I have been in contact with Sony about this, they say the reason is that a lot of customers complained about the black borders so they decided to change to full screen and bad aspect ratio instead. Strange that the Tablet Z2 apparently isn't affected of this then.
I am dissapointed that a feature that was working 100 % when I bought the Tablet Z no isn't that useful anymore.
Actually I bought an MHL cable (standard one and a samsung one) and a DisplayLink* Cable (the one used for nexus) and none of them works.
My v1 mhl adapter crops the bottom off.
dape16, then, as you deducted from my previous message, it seems with the tablet Z2 (even on latest firmware), they took the same route as with the Tablet Z on stock 4.1. You could try to look for some media player app that allows you to play with video aspect ratio to compensate the output.
hasenbein1966, oh, really?
Diomorgan, Samsung and some other brands uses 11 pin MHL, while Sony's devices and some others uses 5 pin MHL. It seems they are not compatible, the best you can do is go to eBay, search for any MHL cable for Xperia Z, Z1, or Z2, and buy it dust cheap.

Can I render the GUI in 1440p?

I'm fairly sure the answer is no. I've just upgraded to a large 1440p monitor for both my PC and the Shield to use in my small room at university. The Windows PC is obviously perfectly happy to output at any resolution I want, and even prompts me if I use anything other than the display's native resolution. The Shield on the other hand has extremely few settings in every department, including HDMI. I get that Google is trying to simplify their various software for the average user but come on, no option to set the output resolution? Ridiculous. Under Settings, HDMI I've set 'HDMI optimisation' to 'best resolution' mode (that's the only relevant setting I can find). I've then restarted and it still appears that the Shield is outputting 1080p and letting my monitor scale it up (crudely). I'm not only going by my judgement of the image quality. When I take a screenshot it saves as 1080p.
Presumably people with 4K displays aren't experiencing such a problem? The device is, after all, supposed to be 4K60 capable.
I haven't tried any custom ROMs (nor do any current ROMs offer a 10-foot UI as far as I'm aware), I wonder if it would help though?
Nor have I looked into using the Xposed framework (which I've only ever read about and never properly used), though I'm doubtful whether that could help.
My problem isn't with 1080p HD itself. As far as video is concerned I can't even tell much difference between 720p and 1080p at a normal movie viewing distance. It's when any GUI renders at non-native resolution that it becomes really obvious and annoying to me.
https://play.google.com/store/apps/details?id=com.nomone.resolution_changer&hl=en
Maybe try this? It's for dropping res to increase performance, but I don't see why it can't increase it too.
This app may also work. It also allows for overscan adjust if you would need that on any other display.

Thanks for the reply and sorry for the delay, I've been moving house.
I got a copy of the .apk for Screen Shift from the developer on that thread and Sideloaded it and used it to change the resolution to 1440p. The result it interesting. Everything on the screen shrinks (presumably in proportion to the increase in resolution).
This proves that the hardware can physically output in 1440p, which is to be expected considering that it is 4K capable. However another reasonable assumption was that the software would be optimised for smoothly coping with 1440p, and it isn't. This is quite disappointing considering that it is a 4K-capable gaming device and that 1440p is a popular choice among gamers in particular.
Curiously I was unable to take a screenshot of what I am describing. I'll attach a photo instead.

so you got thta working somewhat at least. Is everything stretched? It looks fine to me from the picture, but those can only show so much. Unfortunately, the 21:9 market is really a niche, not to say that I don't understand how amazing that they are, I intend to own one someday. Unfortunately for us and Nvidia, Android TV, and ANdroid in general is made to work well with 16:9 ratios as that's what almost every TV, monitor, and phone are these days, or really dang close. On top of that, this is a media box, which you could argue both ways that 21:9 is very nice for ultra-wide movies and also not usefol to many as most if not all blu-ray is 16:9 for most media formats, and games aren't likely optimized for a small niche. It makes sense that they wouldn't add support at this time, and I want support as I would buy a 1440p monitor if they would add support, but it'd be more work for each app, though mostly games, to support an odd ratio, and on top of that, even shield specific games are pretty niche, and then to add a niche feature to a niche product, just isn't monitairly worth the time. Sorry to make this so long, but I wanted to explain the best my tired brain could.
TLDR: It's not worth it for them, but DANG it would be nice. Till then, we have to hope that a monitor will black bar it to 16:9 for us, or that hack to work.

1440p is 16:9, so the 1080p image scales up without needing to be stretched or cropped.
Interestingly with firmware upgrade v2.0 they've added a few more HDMI settings, including one to change the resolution and refresh rate. Unfortunately, despite being connected to a 1440p monitor, the only available options are all 1080p (as shown in the attached screenshot).

Wow, I'm totally not on the ball. Mixing up 1440p with 21:9, sorry about that. It looks like Screen shift did what you needed though. It'd be nice to see that added, but for now, workarounds are there at least.
Hi, im just wondering if the OP ever managed to get his Shield to output 1440p?
Ive been watching some UHD / 2K video trailers on youtube using my PC and i've been blown away by the quality, in particular the "Samsung UHD - Transformers Age Of Extinction (2014)" video ( incase someone wants to check it out).
Ive just upgraded to a Curved 1440p display so I now have a spare 1440p monitor that I would love to use with my Shield TV and finally replace my old plasma tv Ive been using for years. After seeing the quality I can get playing a 2K 60fps video on the display it would be great if I could use my shield tv to play UHD content @ 1440p as the hardware is clearly capable.. I'm just hoping there is a work around to enable it. Even if I need to root my Shield / Install a custom ROM. I've googled and hit a brick wall..
Anyone have any solutions to displaying 1440p @ 60hz on the Shield? (fingers crossed)
Thanks
[Solved] Yes! you can 1440p (2560x1440 @60Hz) with the nvidia shield. just:
1) Enable developer options (search for tutorial ,easy)
2) Go to: Developer Options > HDMI section > Show all supported modes in custom display modes> enable.
3) Settings > Devices Preferences >Display & Sound > Resolution > Select to match the resolution of your monitor.
While you are there, may be you want to force Advanced Display Settings > Dynamic Range to Full to match the full RGB input of your monitor. Mine a Monoprice IPS27 shows washed out colors by default with Nvidia Shield, switching to full RGB solves the issue
Have a good day!

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:

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.

Screen Mirroring to Samsung 4K TV

Has anyone here who's used the screen mirroring to tv function of our phone, when used the picture quality on the tv seems a bit off almost as if the gamma or brightness setting has been turned up a bit too high.
The picture on the tv is NOT the same as when I look down at my phone where the image is crisp and the colors are more richer.
My tv is a samsung 4k 65" with the latest firmware.
I have also tested screen mirroring to my tv from a NOTE 3 and the results are virtually identical.
Also keep in mind I've tested the phone sending my tv HIGH RES 4k content as well as otherse 1080 , 720 and the results are usually the same in terms of colors being a bit washed out.
I'm trying to avoid wasting money on a xiaomi android box since it wouldn't be needed as I can screen mirror for free from my phone.
Appreciate any feedback.
I've searched the net high and low for my answer and haven't found any resolutions to screen mirroring to my samsung tv.
does no one else notice this when mirroring to a tv screen ?
I really would appreciate some feedback / validation on this.
Thanks
