I realized last night that my 1920x1200 display is scaling the Chromecast 1920x1080 signal to a full 1920x1200 resolution causing the entire display to be stretched vertically.
When hooking up the same display to my PC via the same HDMI port at 1920x1080 resolution, I get a 1:1 pixel mapping with black bars on the top and bottom of the image. Is there something in the image source that specifies whether to stretch or use a 1:1 pixel mapping? I went through all the settings on the monitor and nothing will give me the proper aspect ratio.
Same here, have you found a solution? It sucks!

You sure your TV isn't set to Stretch as opposed to normal?

Have you double checked all scaling options of your display? This user contacted Google to let them know of the same problem:

I just plugged the Chromecast in, and it updated (had been sitting on the shelf for a while). After the update, the same problem is exhibited. I have 2 aspect ratio options in the monitor settings, "Full" and "Fit". Both provide a 16:9 1920x1080p signal stretched to the 16:10 1920x1200 resolution.

The other way around: If you have a 1920x1080 display and want to mirror the display of Android device wich has a 1920x1200 resolution, use this app the app "SecondScreen" (https://www.xda-developers.com/cast-device-second-screen/) to set the resolution to 1920x1080 before casting to the Chromcast.
Its goal: "Second Screen aims at providing you with a way to properly cast your screen so that it looks is best whenever you are showing it off to your friends and family. It does so by allowing for a user selectable resolution and even DPI in order to take full advantage of your TV."
Chromecast2 on a HP 1920x1200 display
Louer Adun said:
Yeah, that's what it seems I need is a 1:1 pixel mapping. However connected to my computer this monitor will have a letterbox when set to 1920x1080 and the expected letterboxing.
Please note I only tested this with the first gen Chromecast, so maybe this isn't an issue with the second gen units.

I tested the Chromecast2 on a HP 1920x1200 display. Pixels are mapped 1:1 with the right display settings. I don't have a Chromecast1 to check with this display.

Why when I connect the TV to 2x OPTIMUS
Pixel stretch
Even when taking pictures in FULL HD
Even in games
In Cell Phones see so beautiful
But not on TV
Apart from two sample movies I got with the device
The phone's resolution is 800x480, your telly's resolution is 1280x720 or 1920x1080.
Not hard to figure it out
Yes but when taking pictures in FULL HD
This basically
1080P?
So ...
Or I copy a tape device in MKV in HD
This should be the quality of HD is not it?

*when taking pictures=when i taking video...
Mine doesnt strech on the screen. If the phone is upright it shows the image upright, with big black sidebars(No stretching). When the phone is laying down/playing video the image is not scaled either, and fits the screen quite nicely.
The user interface is upscaled to 1080p, so the menu, items, apps, ... are all upscaled.
Only the video mode (and maybe game mode) is native 1080p.
I've fiddled with my phone on the tv and I see no stretch.
Are you sure that the TV itself doesn't have a picture stretching mode enabled?
Many TVs have them on by default to adapt 4/3 (99% of non cable/satellite transmissions) content to their screen.
Modes are various and go by different names,but these are the usual:
linear stretch, content is stretched over the screen, so it gets "fattened"
zoom, content is cropped to fit aspect ration and then zoomed, this usually gives good results on films because they have upper and lower black bands which gets deleted, and then the rest has the size of the tv and fits all the screen
hybrid stretch, central part of the content remains the same, the content gets stretched the far it is from the center (stretching on the lateral edges, it gives an effect similar to a wide lens)
I tried the tvout with the offical hmdi adapter but it mirrors the tablet including the system bar, and since the resolution of the tablet is 16:10 and not 16:9 I get two black vertical stripes at both sides.
Is there a way to change this behavior? Like a full 16:9 or a 1080p out?

You'll need to change the settings on your TV to stretch the picture or zoom it, most TV's have a setting to automatically do this to hide black bars, the only problem is it alters the shapes, people end up with odd shaped heads etc
So basically there is no way to play on a tv a 16:9 fullhd video or a slidewhow without status bar? I mean, is mirroring the only one mode?
You can set this up to hide the status bar, but 16:9 is always going to be an issue as the tablet is not 16:9
Yes, but still tvout is a limited feature since I can't have an extended desktop or i.e. a slideshow played on tv while working on something on the tab...

Hang on......so you want to play a video to the TV in HD widescreen while still doing something on the tablet ?
I'm pretty sure there's no Android devices that do this
A kind of... My first aim is to play a slideshow on a tv in full screen mode, while seeing the slide's tree on the tablet and choosing which one to show in full screen on the tv.
Second aim is to disable tablet video and show only tv. It would be nice to play a 3d game on the tv, but as long as the video is doubled fps are so low that it's unplayable.
FPS won't be doubled as all you're doing is doubling up the video output, not the data going through the GPU, there's plenty of video's on youtube of folks using MHL adapters to connect to a TV to play games
Yes fps won't be halved but, since a tough game is very cpu intensive, doubling the video it lags a lot more the tablet. My tablet is much more laggy even simply swiping on the home screens or app drawer when connected to a tv.
Flash motley kernel and overclock to 1.4
I believe a Nexus Q will let you send video from the tablet to the TV whilst doing other stuff on the tablet, but it costs quite a lot.
Definitely hear some unrealistic multitasking wants. Also, doesn't ICS improve hdmi out options as far as full screen video, not just mirroring?

The Galaxy note 10.1 has this function in the movieplayer to only show the video while controls are shown on the tablet. This is exactly what you are asking if i understand you correctly.
I'm also looking for more possibilities in this area. Being able to see the picture Gallery while only showing the last picture (or non at the start) would be amazing!
If i find anything i will share it here
Both the nexus 4 and the nexus 7 (2013) support slimport, which is very useful for mirroring the device to a big screen. However, neither device uses the standard 16:9 (1080p) aspect ratio. As a result, you end up with some cropping on a 1080p TV. For the nexus 4 it is even worse, since it outputs 768p upscaled to the TV's resolution.
However, the flexibility of android allows us to manually change the native resolution. In a console, we can type the command:
wm size 1080x1920
and the resolution will change. In the device screen the new resolution will look odd, however you now have true 1080p on the TV. To get back to the default resolution you type:
wm size reset
This solution works, but it is not very convenient. So I made two profiles for tasker, that automatically change the device resolution upon the connection of an HDMI cable and reset it when the cable is disconnected, thus automating the whole process.
I 'm attaching a screenshot of the two profiles, as well as a zip file so you can extract and import them in tasker.
In summary,
- you need root
- the HDMI plugged profile
reduces the device brightness to minimize battery consumption
increases volume
sets resolution to 1080p
enables WiFi
sets display timeout to 10 hours
activates display rotation
- the HDMI un-plugged profile
sets auto brightness back on
resets screen resolution
sets display timeout to 1min
These are optional settings that I found useful to automate, but they are all optional, and you can tweak them once you imported the profile to tasker.
I hope you find this useful!!! :good:
before i buy this tablet, i need to know if it is possible to change the screen format from the stock 4:3 to the more useful 16:9 in a custom rom or kernel or whatever? i didn't see this asked anywhere, and it is black friday, so i need to find out quickly as i need to make a buying decision. thanks for any help!

What do you mean change it? It's physically and natively a 4:3 tablet.
However you can use the tablet in which ever orientation you please.
If you turn it 90 degrees to landscape mode it becomes a 16:9 tablet, but you can t physically move the buttons.
You're better off buying the tab S if you want native 16:9.

what i mean, is like on a computer, you can change formats of videos or games or what not, from 4:3 to 16:9, so you don't have the large black bars on the screen while viewing one of them.
Er?? Then you either have a totally distorted picture (all things are too high in relation to their width), or you must crop the left and right sides to fit the picture into the 4:3 screen.
If that is what you want... but it is not very reasonable to want it...

What you ask doesn't make sense, you can't physically alter the ratio of something without distorting the image or cutting part of it off.. If a video is 16:9 it must be played back at 16:9 regardless of the physical dimensions of the device.
If you don't like black bars then you would have to use a player such as mx player that allows the image to be stretched to full screen.

You can't not even a computer in proper look. From 4:3 ratio resolution to 16:9 ratio resolution will make everything look stretching and distorted.
Hi all!
On the OnePlus tablet, the aspect ratio is 7:5, so the resolution is also not standard: 2800 × 2000 pixels...
All this together gives a pixelated / square picture in the lobby and in battle (regardless of the selected graphics quality settings)
Is there any way to actually fix this? There is a strong feeling that the game did not correctly "understand" the screen resolution
Thank you in advance

I am pretty certain that this has nothing to do with the OnePlus Pad so there wont be any settings embedded to change this. It should be an issue/bug with PUBG since it hasn't been configured for the particular aspect ratio of the OnePlus Pad as the device is pretty new. They should be working on a new patch update to fix this issue so make sure to keep the game up to date at all times!
Thanks!
@Deselver Only way to workaround this for now is by changing the resolution of your tablet entirely. The game is optimized for 20:9 or 16:9 aspect ratios. Using 1650x2800 worked for me, YMMV, also this solution requires root.
