Desktop Option Producing a long/stretched image

[ApocTheWeeb]

I have two screens. One supports 1920x1080, while the other supports a lower resolution of 1366x768. When I try to use the Desktop option within SteamVR, I get a very wide/long desktop that is stretched diagonaly. I can still interact with the desktop, but it is so stretched I can't tell what I'm doing and it's essentially useless. I know that if I unplug my smaller screen and restart my computer, the Desktop option looks and works perfectly.

Any tips on how I can fix this issue? I would like to have use of both my screens and not have to restart my computer every time I want to play in VR.

I have the same issue, any help would be appreciated

The fix is kind of simple. Your secondary screen is using a non-standard resolution, so it is causing an issue. You have to go into your desktop display settings and manually set the resolution to something like 1600x900. Check your display settings and more than likely, your secondary screen will already be close to what it needs to be, just slightly off. You will get a warning when you try to manually change/enter the resolution, but unless you're trying to get 1920x1080 on a decade-old screen that is meant for 1600x900, it shouldn't be an issue.

The fix you suggest doesn't seem possible, because as far as I'm aware, I'm not using non-standard resolutions.

I have two displays.
3840x2160 (4K UHD, monitor via DisplayPort)
1920x1080 (FHD, projector via HDMI)
and the HTC vive, via DisplayPort
I'm pretty sure those are standard resolutions. The interesting thing is that it worked fine when I just used my 4K monitor, so there is something else going on.

I'm pretty sure Steam is misinterpreting my screen resolutions in general, because when I go to Steam > Help > System information, it is reporting the following:
- 2560x1440 for primary Display Resolution
- 5760x1450 for Desktop resolution

That primary display resolution suggests WQHD instead of 4K, but I think it is because I'm using Windows' 150% UI scaling. But because everything worked fine before I attached the projector, I don't think 4K support is necessarily the problem.

Performing a printscreen results in an image of 5760x2170, so even if Steam were using the desktop resolution, it wouldn't be taking the height difference of the two screens into account. Also, I wonder where those 10 'extra' pixels in the height are coming from.

Only way to fix I know is using DDU to completely wipe your graphics driver, then reinstall.

Works for a while..

You need to get your screen resolution to something that the Steam Desktop view understands/can translate into the VR. I doubt it is (currently) set up to handle a resolution of 5760x1450. Did you manually set and ensure that your desktop resolution is set to 1920x1080 via Windows Display settings? Also, ensure that your Graphics Card utility isn't trying to treat both your screen as some sort of large connected screen, as that appears to be the case. 3840 + 1920 = 5760. It doesn't so much matter what your screen is rated at, but what Windows is intrepreting it as. I had a secondary screen that was 1600x900 (It was small and meant for IRC/TS3/Discord/Other chat programs), but Windows was displaying at some odd resolution that was kinda close to that, but not quite. Funny enough, it just randomly happened one day as prior to my getting this issue, Windows 10 (and the SteamVR Desktop view) saw the screen correctly.

I would double check the Windows Display settings. If they are correct, I would then do what Kief suggested and completely wipe your graphics drivers and reinstall the latest.

I don't know what happened, but I haven't had this problem in a while. maybe it was fixed? Still using the same weird resolutions.

Now my main concern is the fps drop in Desktop view. and how the mouse button click doesn't work in certain situations.

Each screen is set up to their native resolution using Window's standard settings (i.e.: 4K at Windows' 150% UI scaling, and 1080p at 100%)
Having one giant 'virtual' screen is how Windows multi-monitor support works. Steam simply doesn't detect it correctly.
