#StackBounty: #drivers #nvidia #graphics #multiple-monitors #gpu 3rd Monitor Not Visible, showing 'X' cursor – Dual GeForce GT …

Bounty: 100

So i bought 2 GeForce GT 1030 cards and want to run 3 monitors on them simultaneously. 2 are connected via HDMI and DVI respectively on the first graphics card. These are the only two that show up in the output of xrandr.Additionally only the 2 monitors on the first graphics card show ubuntu on the screen.

The fact that both the graphics cards are the same model and 2 of the screens are the same model is probably not helping.

Nvidia-settings is able to see them, however it is not possible to put them on the same xscreen it seems. Or use xinerama.

The problem is somewhat similar to t this – 3rd monitor showing "X" cursor however i can’t get the X cursor to show up on the third screen, its staying lit green, but no input.

#StackBounty: #multiple-monitors #display #display-resolution Bug using two Monitors with different resolution

Bounty: 50

I have a very confusing problem.
I’m using Ubuntu 18.04 with 2 monitors
My main monitor (15.6″) has a resolution of 1920×1080 and my second one is 28″ with a 4k resolution.
When I’m using my two monitors with different resolution, then i can’t use the menu bar in programs which are displayed on my primary monitor (15.6″)
I’m also not able to put icons on my primary screen and I can’t rightclick in programs which are located on my primary screen
When moving these programs on my 2nd monitor everything works as it should

Now when i change the resolution of my 28″ screen to 1920×1080 then everything works as intended on both screens

Does someone has a clue what could be the culprit of this problem?

EDIT:
Noticed a strange behaviour
my screens are arranged in this way

+----------------+
|                |
|                |+---------+
|                ||         |
|                ||         |
+----------------++---------+

in this way the problems described occur on my right screen
but when i move my smaller monitor up to the upper border of my big screen like this

+----------------++---------+
|                ||         |
|                ||         |
|                |+---------+
|                |
+----------------+

everything works as it should

#StackBounty: #windows-10 #multiple-monitors #nvidia-graphics-card #screenshot #widescreen 21:9 monitor taking squished screenshots

Bounty: 100

I have dual ultra wide LG 21×9 monitors.

They mirror each other.

When I hit print screen and then I paste it to a paint document for example, it’s completely squished horizontally, as if the PC thought it was 1080 regular and tried to compensate.

I don’t mean it only takes a 1920 screenshot, it’s actually squished further. Unable to find any fix as of yet, lots of software and searching has produced the same results.

RTX 2060
NVIDIA drivers detect 2560×1980
Windows detects display(s) at 2560×1080

Monitors only have original and auto wide as options.

#StackBounty: #windows-10 #multiple-monitors #hdmi #resolution How to increase resolution maintaining Hertz

Bounty: 50

I have a Samsung SyncMaster 932MW LCD TV, that I connected as a secondary monitor via HDMI to my laptop AsusVivoBook S15 X510UF with Windows 10 build 1903. It has an integrated Intel video card and a Nvidia GeForce MX130. The CPU is an Intel Core i5.

The only frequency the TV supports is 59Hz and the only resolution with that frequency is 640 x 480. The thing I don’t like (before the resolution) is that with low resolution, Windows makes things bigger, and so It’s very difficult to work with (the app and other elements dimension is set to 100% in Windows settings, so it isn’t possible to lower it).

Also, in the higher resolutions, there isn’t even one with 59Hz.

How can I increase the resolution while maintaining the refresh rate?

Bounty: 50

I have a dual monitor setup with each monitor capable of playing audio, connected to a single RX5700XT GPU.

Right now I can select either one from the Sound settings to be the Output device.

enter image description here
enter image description here

What I’m trying to do is to combine the two into one Output device so I can play audio with the two monitors simultaneously. What’s the easiest way to achieve this?

Thank you.
