Bounty: 50

I am gamer/programmer on Windows 10 64 bit Pro edition who plays/works at 1920 x 1080 resolution with the need to minimize my game to get to windows which is running at the same resolution. I am using 2 insignia monitors in ‘Duplicate’ mode with a GTX 970 Nvidia Graphics GPU

The issue I am having is that my monitors are receiving a resolution switch signal each time I make the switch from game to desktop or vice versa, despite that the game is played in 1080p and that the desktop resolution is also 1080p.

To understand this further you should understand that when I normally change resolutions in Windows, my TV produces an OSD showing which resolution is in effect. While this is considered normal behavior for the TVs that I am using while switching resolutions are waking from sleep, it is not normal when the resolution is not actually changing and that the devices are already on. Here is a shot of the OSD that pops up when I switch to game in the same resolution as the desktop:

enter image description here

After doing some testing I came to realize that the issue does not happen on either monitor when only one monitor is selected in the display settings (either when PC screen Only or Secondary screen only are selected). If Duplicate mode is enabled the issue is persistent.

enter image description here

So what I would like to understand (and correct if possible), is how Windows 10 and my GPU are handling the different monitor setups. There must be some technical explanation for why my hardware (monitors) are behaving differently in these different Windows monitor modes.
I would like to keep Duplicate mode enabled so I dont have to constantly switch between setups to accommodate this issue.

I tried the answer from this response but what I got is:

PRIME Displays cannot be controlled by nvidia-settings and must be configured by an external RandR capable tool.

That means I cannot control the displays thanks to nvidia settings. So I believe I have to use a RandR capable tool but I have no idea how. Must of all, I had no idea it’d be so difficult to change my screen resolution. How should I do it?

EDIT thanks to comments: my laptop is a Dell XPS 7390.

I tried with propietary drivers of Nvidia and Nouveau’s drivers, and I have the same result.
On Ubuntu 18.04 with the LTS Kernel (4.15 was?) works perfectly. Same with Windows 10.
Since 19.10 it doesn’t work.

The nvidia-drm modeset is on 0 (nvidia-drm modeset=0).

Laptop: Asus
Intel: i5-6300
Graphic card: Nvidia GTX960m

PD: With nomodeset it works perfectly. But still, it doesn’t work with propietary drivers and nouveau.

PD2: I tried with only Nvidia and only Intel graphics. No results.

PD3: I tried with a Live USB and it doesn’t work neither the second monitor. This just detects a second monitor, but in the second monitor the only thing I can see is a blank screen. I’m tired trying to make this work seeing a lot of pages. Please, if anyones can tell me if someone had a similar problem or what I can do. I don’t want to use again W10. Thanks!

#StackBounty: #multiple-monitors #display #hdmi #amd-graphics Old LG screen/tv no signal on HDMI

Bounty: 50

When I run xrandr when the screen is off I can see the HDMI port “connected” with all the screen resolutions options fine.

However, when I turn the screen on, I just get a blank screen and when i run xrandr again the HDMI port shows as “disconnected” and I can’t see any resolution or what so ever.

My video card is AMD 480 and trying to run Ubuntu 20.04 but have been having this issue with older versions of Ubuntu, actually its one of the main reasons I didnt switch to Ubuntu yet.

Note that my screen is working fine on Windows 10.

#StackBounty: #linux #ubuntu #display #multiple-monitors Linux: How can I duplicate my desktop and show it side-by-side on a single scr…

Bounty: 100

I have a custom VR device I’m testing and I’m looking to do something which should be simple with my desktop monitor settings. Essentially I want to go from a regular desktop, this:

enter image description here

To having this screen repeated side-by-side split down the middle, like this:

enter image description here

And it’s literally just a real-time copy of the desktop.

For reference, I am using a 800 x 480 display, in case that’s relevant.

Ideally I would like to put my computer permanently into this display mode, so that every time it boots up it’s like this automatically.

Thanks in advance for any help!

EDIT – I want to confirm that I’m trying to do this simple task on a Raspberry Pi, which should be a type of debian Linux if I understand correctly.

#StackBounty: #multiple-monitors #displayport #usb-c #daisychaining DisplayPort over USB-C resolutions

Bounty: 50

I have the following equipment:

I’d like to be able to connect the laptop to the Dell monitor with a single USB-C cable, and then connect the Dell monitor to the HP monitor with a single DisplayPort cable. This should also charge the laptop. When I do this, though, Windows won’t let me set the HP monitor to its full resolution (it just doesn’t show anything higher than 1920×1080 in the list). For now all I can do is connect each monitor to the laptop with a separate USB-C cable, which does work, but I would prefer to only connect one cable to the laptop (for convenience). Is there any way?

I have connected a second screen with built in speakers to just watch YouTube.

I would like audio for programs on this screen to be sent out the speakers on this screen, but have found this is difficult to achieve.

I have to mess around with the settings, but can’t really get them right.

Ive found per-app output, and this appears to work for apps like Spotify, but I want something like per screen output.
