Anything else we should know?
My computer is set up in this config: https://i.imgur.com/FuwMPkb.png
I have two video cards. GPU 1 goes to center screen via display port. It is also connected to a Valve Index (behavior still happens with Index unplugged) GPU 2 goes to screens 2,3, and 4. 4 uses a DisplayPort to HDMI adaptor, but is always on (drawing tablet)
When I power off screens 1,2 and 3, Windows sees the new layout as the following: https://i.imgur.com/IT4hdNe.png
The main display screen is not being seen.
When I turn everything back on, it returns to the first image.
When I turn on OBS Studio, the display capture will have done one of the following: Defaulted to capture screen 2, 3, or 4. It is not returning the capture to the center primary screen. OBS was never opened when the monitors were turned off.
Tried all three, Auto, DXGI and Windows 10 mode. All three are doing it. I cannot find out a pattern, but it will not do it if I turn OBS off and back on immediately, and/or turning a screen off and back on. It only tends to happen overnight, after the screens are turned off for several hours, and then only back on will do it, which is why it took a few days to respond to this to test the different settings.
We've changed how displays are identified for OBS Studio 29. Please retest in OBS Studio 29 Beta 2 (or newer).
Testing displayport on 29 beta 2 and it seems okay for me. The capture did not jump to the other monitor when following the reproduction steps.
Confirming on my end as well, I had all 3 DP displays configured, and all 3 successfully returned to the correct sources after several times of plugging/unplugging the cables (as well as just power-cycling the displays).
Tested 3 times, no issues.
Am currently running update 29, and it is still happening. Was happening on version 28 as well.
Going back to the first image in the OP however, one thing I have noticed is that to this date, it has never captured screen 3. It always seems to skip to 2 or 4, which become screens 1 and 3 when the single display port screen is shut down.
If there was a way for it to find the last screen that has a specific res for example, would be nice, as my main screen I am trying to capture is 2k and all the others are less then that.
