Found a bug to enable 1080p in mirroring mode (glitchy)

Hi all,
I could not sleep thinking of using chrooted linux on my 47" 1080p LCD, fine, but we a re limited to the hdmi mirroring, which is 800x480 stretched to fill the screen.
Thinking about the video player, which does proper 1080p output I tried to fool the system somehow with video playing and task switching, menus, back btn presses, and found something:
Using temasek´s kang + ironkrnl #251 32mb hack, qemu lcd density 210
You start playing a video, can be through native video player or mxplayer, HW or SW mode, then you press menu once or twice to show the options, the video freezes for a moment. then you press back twice rapdly, VOILA, you have a working gallery (works until you flip the phone to portrait, this resets the display to normally scaled screen) in 1080p in the lower half of the screen.
If you were using mxplayer, the top half of the screen will have the player controls as they were on the phones screen during video playback. everything is repeated side by side almos three times (I think it´s the difference in resolution being compensated in the framebuffer or some sort of scaling bug).
All in all, does someone have any idea on how to invoke a mirrorless 1080p picture on hdmi? (or mirrored and downscaled/croppped on the phones screen), apparently only gallery is capable of displaying in 1080, any other app works in the phones screen but the image keeps frozen on hdmi with sound ok.
Imagine chrooted linux in 1080 with BT mouse and KB!
Pictures attached:
edit: tried with 1202221503-ETaNa_48 kernel and could not reproduce it, later will try with etana 64 and other ironkrnl

What a great little bug. It would be nice to have it actually run at 1080p for the Android screen and things like the word processor. Would make using the phone as a mini computer so much better.

Great find dude...!!

Sould I post this at Development section? Can some mod move this thread to dev? I think it will be more useful there.

Not development. Moving to general.

I can only say that I wish I had the same amount of spare time as you

HDMI tv out, only mirroring?

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

Screen resolution - stretching?

I actually realized this since the first day of using the tablet... I noticed that the screen actually got stretched when you set your tablet in landscape mode and squished in while in portrait mode.
I suspect that the OS is running at a wrong native resolution... Does anyone have similar observation?

Yep, me too
I noticed the same issue. Circular icons look especially bad. Funny enough, the tablet on the packaging also has a distorted screen. In Youtube, videos have black bars on the top and bottom of the screen. This shouldn't be the case, as 1024x600 is a 16:9 aspect ratio, and videos are typically 16:9.
Code:
adb shell dumpsys display
contains the following output:
Code:
mPhys=PhysicalDisplayInfo{600 x 1024, 59.670002 fps, density 1.0, 177.209 x 171.115 dpi, secure true, appVsyncOffset -5000000, bufferDeadline 22758840}

Yup, installed luna icon pack and looks horrible. Same as letters in Google keyboard.

I was just getting on to post about this very thing. Here is an image comparison I put together showing a screen shot side-by-side with a photo of the screen:
https://drive.google.com/file/d/0B0Z0bpkQXwBFR1djTnJLSGlsTkU/view
According to the images I pulled, the nominal screen resolution is 600x1024, which is also the hardware spec. But the actual image you see is the same aspect ratio as a display with a resolution of 600x1080. This suggests that the display pixels aren't actually square. I tried a couple of resolution changers in the Play Store but they just scale the display without addressing the issue.
I found an old Google Groups post asking about a cheap tablet with non-square pixels, and the answer in 2012 wasn't very encouraging. I wonder if something could be done through an Xposed module?

I lowered the dpi to 150 just to test and same result...

Also, this line from the display dump above similarly seems to indicate non-square pixels:
Code:
density 1.0, 177.209 x 171.115 dpi
Anyone know how to change horizonal and vertical dpi independently?

Apparently the dpi is 160 normally.
You can set it higher and the icons will look less stretched but the dpi seems correct.

Yeah, this is sadly typical in cheap chinese tablets. What really surprises me is that almost nobody talks about this, and most of the people don't even notice it even after pointing it to them
I've also noticed that this screen has what I think is a slow redraw rate (i. e. painting line by line from the top) which cause funky scroll effects, especially in dark backgrounds in portrait. Grab the tablet with the buttons on top and scroll quickly in the Kindle Store and you'll see it

I watched a video on the Fire for the first time, and while this isn't exactly a scientific test, the video did not seem stretched out or distorted to me. I tested with a second video and it too seemed to display with the correct aspect ratio. If so, then that suggests that the display, controller, and drivers are all capable of rendering an image that is not distorted, and that it may be an issue with the rendering of the Android UI.

Up, i would love having a fix for this.

Mine doesnt seem to show these problems? Is it just a some devices problem or am I missing something?

Just got one of the $50 Fire tablets delivered and this is one of the first things I noticed. Look at a circular icon when it's in portrait and when it's in landscape and it's really obvious. I noticed it on the Pinterest icon.
If this really is a hardware issue, I don't suppose there's any way to fix it? If not I'll probably return it and get my money back.

Idk.. I don't really notice it maybe it's just my perspective the seem good to me.

It didn't jump out at me, but yes, the screen is definitely wider than 1024/600. Maybe it is 16:9.
I did notice the weird scrolling. Perhaps it's refreshed in some interlaced fashion?

I've noticed that some people just don't see it. Coincidentally in my case it was the same people that watch 4:3 content stretched in their 16:9 TVs and are happy with it

^^^ This!
The incorrect aspect ratio is really distracting. I hope there's a way to fix it now that custom ROMs are available.

Hey guys! Does anyone else have a problem with scrolling. When I scroll down a page it looks like the left side is scrolling slower than the right. So for example, if you scroll down on a page full of horizontal lines or text, all the text slopes to the right until the page stops. I'm not sure if this is normal because the tablets so cheap or if its just mine?

It seems "normal" for this tablet, sadly:

Can't complaint it's rather solid for it's price imo.

Aghh glad its not just mine then. I'm loving the fire! Though it was going to be rubbish but really surprised!

[Question] Pixel 5 screen resolution change fix?

Hi guys,
I used to use this method with mostly all of my devices in the past: LG G3, Galaxy S5, Amazon Kindle Fire tablets (including 8'' and 10''). All of them work just fine. But not this Pixel5!
Using the "adb shell wm size" command. I changes the screen resolution of my devices down a notch, for example from 1440p to 1080p, or 1080p to 800p and so on. Then I adjust the density accordingly. They all turn out the Ok-ish screen resolution and have a much better GPU performance for gaming.
My current S10 has the native changing resolution from Samsung, So I don't use it for my S10.
But with the Pixel 5, there is a problem. The camera cut - out on the screen become so weird and placed on the off center position, and the Pixel 5 is unusable
I really love to use my pixel 5 at 720p or 900p, and I believe the Adreno 620 (snapdragon 765G) on the Pixel 5 will handle game at the lower resolution much much better.
Does anyone have a fix for this? please help!
Thank you for your reading!
P.S: OMG, this was my bad for posting the thread into the wrong sub-forum. It was on the other tab of my web-browser. Thank you very much for moving it to the right place, Moderator!!

Why are you not changing the resolution in the settings like you do on the Samsung? A quick search suggest the Pixel 5 has such an option. You're best doing it the official way to guarantee everything will work correctly.
Because you're changing the resolution and DPI through what is basically a developer option, I think whatever is handling the camera cutout (An app? The WM? Android?) is not updating its position and that causes it to be misplaced. Therefore, I dont think you find a simple fix for this. Sorry.

You must be mistaken the Pixel 5 with other phones, since we don't have the option for such a changing the resolution in the settings.
If you mean the display size? It's just a density change, not the resolution.
Thank you for your contribution anyway!

Hi, have you sovled the problem? I encountered a similar condition.

Question OnePlus Pad. PUBG mobile screen resolution problem

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.
