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!

thinking about buying the galaxy tab s2, but...

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.

Can you hide the teardrop notch in YouTube playback

Hi Guys.
Interested in getting this device but was wondering if the teardrop notch can be hidden during YouTube playback

According to the early reviews on YouTube, there's no option to hide the notch in MIUI, so I doubt you'd be able to in YouTube, I could be wrong though

can we remap assistant button on Chinese version to Google assistant?

wondering does most ppl prefer to crop youtube or any video just for fullscreen experience?
own 18.5:9 phone but most youtube video still 16:9 or new 18:9 (rare).
mi9 already have 19.5:9 screen, i will never crop to make top and bottom video gone just for full screen experience

In the GSM Arena review they play a game, and at either side I don't see a notch. It's really odd, because it doesn't look like there is, say, a black border around the notch either.
I will be interested to see for myself when my phone arrives

Any way to force snapchat into 16:9 aspect ratio?

I really don't like sending tall 19:9 aspect ratio photos to my friend that has 16:9 phone. I already disabled the notch and enabled the navigation bar so that reduced the screen a bit, so that's now maybe a 18:9, but my friend still sees black bars on to the sides of her phone. Any more tricks like this, any way to open an app with a different resolution? I don't have root and I heard it's a complicated process to get it, so I would prefer not to do that.

Try changing your resolution to 1080p (not 1080pi) with adb

But that would change the resolution for the whole device, right?

Yeah, maybe try using Tasker? I'm not sure if it allows you to use commands like that if it's not rooted. If it does, you could just run that command when the app's open and the revert it once you close

hey OP, how did you enable the navigation bar to stay in snapchat?? i'm looking for a way to do this?

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.
