I have a problem that I would like to hear any kind of solution to the respect.
It is a videoWall of 8x2 monitors managed by a single server with the following characteristic.
Nvidia Quadro NVS 810 (in total there are 2 graphics cards with 8
outputs each, they are cards with 2 integrated GPUs each)
Driver version: 515.65.01
OS: RedHat8
Desktop: Xfce
The problem we have is that when we start to fill the video monitors, it starts to slow down a lot. We have verified that it is not a CPU load error or a bandwidth error since it happens to us with both network video and local video.
I have tested with composer and without composer of the Xfce desktop.
I do not know if the fault is at the hardware level due to performance or limitations or some type of configuration at the software level.
This is our Xorg.conf configuration for all 16 monitors.

Here would be the output with the nvidia-smi command at the time of the full videoWall.

I would like to hear any type of opinion to try to solve this type of problem.
Thank you very much.

pixelated view in android emulator
It start giving me pixelated view after upgrading android studio
Downgraded emulator to previous version still giving me pixelated view
Changed dpi, override dpi settings like mentioned in other solutions doesn't work
Currently using my phone for now
Pc Specs

1360x768p display resolution with 100% scaling
Emulator has pixel 4 device android 11 with default setting
I downloaded the example Deferred Lighting provided by Apple in its documentation. Xcode compiles it with no errors but the colors are basically all green (see Screenshot). It could be due to my graphics card but I don't know how to fix the code accordingly. I tried to change pixel formats but none seems to be a fix. I have also noticed that the Albedo + Shadow GBuffer is saturated (see Screenshot) and might be the cause. The sky box looks as it should, instead.
MacBook: Pro (15-inch, 2018) with 2,9 GHz Intel Core i9
Memory 32 GB 2400 MHz DDR4
Graphics: Radeon Pro Vega 20 4 GB and Intel UHD Graphics 630 1536 MB
I'd like to upload my app to the appstore.
Just need some screen grabs 1242 x 2208.
In xcode 8/simulator i could set the size of the simulator to 50%, 100%, etc. and then take the screen shot.
But with xcode 9/sim the options are either 50% or actual size and while 100%, 200% are still there they are disabled. SO my screen grabs are like 500 x 700 or something similar.
And I have an old 5s so that won't help anyone.
Thanks.
I use my iPhoneSE and iPad Mini for my screenshot submissions. Never had any problem. Here's the steps:
Connect device to Mac.
Open QuickTime, choosing menu option File | New Movie Recording. (This sets up a “perfect” StatusBar.)
ALSO: If screenshot uses UIActivityController, turn Airdrop OFF.
Select device, take pics.
Import to Mac. (Airdrop, tethered connection to Photos or iPhoto, etc.)
Using Preview, resize iPad screenshots to 2732 x 2048, and iPhone screenshots to 2208 x 1242.
Note: My sizes are for portrait, but landscape works just the same.
As mentioned above what is the target resolution for the Apple TV? For example like the iPhone 5 was 640x1136, and the iPad was 768x1024. I know that TVs vary in size so there is no definitive size. But maybe a recommended size would work to have a starting point. Like having a fixed height and adjusting the width of the app to fit the tv.
The Apple TV standard resolutions for a modern 16:9 television are:
1920 x 1080 (1080p Full HD, preferred if supported)
1280 x 720 (720p for a HD Ready television)
858 x 480 (480p SD)
The new Apple TV runs apps at a standard 1920x1080 resolution at a 1x scale. This means that, when building tvOS apps, the screen size, in points, that you must use when building your interface is also 1920x1080.

I have a Surface Pro running an HTMl/CSS/JavaScript Store App on Win8.1. There's a standard HTML select menu like this:
<select>
<option>Option</option>
</select>
When you tap it the select menu expands to the full width of the viewport. This is reproducible within the Visual Studio/Blend Simulator at the 1920x1080 140% scaling resolution.
Any ideas as to why this is happening and how it could be resolved?
Here's the simulator at 10.6" 1920x1080 #140%
Here's the simulator at 23" 1920x1080 #100% (app is blanked out)
Thank you
