Question / Help Black screen on Display Capture - already tried everything

[Giffyguy]

(Complete log at the bottom of the post.)

I need to use Display Capture to record a PowerPoint presentation on my laptop with NVIDIA GPU.
(Window Capture can't pickup a fullscreen PowerPoint presentation, so I have to use Display Capture instead.)

Display Capture requires OBS to be running on the integrated Intel GPU, and not the NVIDIA GPU.
I configured this a year ago, without any trouble.
I'm trying to configure it again, and it won't cooperate this time.

My laptop has an NVIDIA Geforce GTX 860M, running Windows 10 Professional Edition 64-bit.
I am running OBS in compatibility mode for Windows 7, and running OBS as administrator.

I have tried configuring OBS in NVIDIA Control Panel to force it to run on the integrated Intel GPU - made no difference.

I have:

1. completely uninstalled OBS
2. completely uninstalled ALL NVIDIA products
3. ran CCleaner to purge any leftover files from these programs
4. ran CCleaner again to purge the registry of any leftover registry entries from these programs
5. reinstalled NVIDIA GeForce Experience from scratch
6. reinstalled NVIDIA graphics drivers from scratch, via GeForce Experience
7. reinstalled OBS from scratch
8. tried again to force OBS to run on the integrated Intel GPU, via NVIDIA Control Panel - again, made no difference
9. still can't create a display capture in OBS

One of the weirdest things is, OBS shows up twice in NVIDIA control panel (see screenshot below) - even after reinstalling everything.
If I click on the bottom listing for OBS, it redirects me to the top listing - but for a single instant, I can see that the bottom listing has different configuration options than the top listing.
I tried getting around this by going to the Global Settings tab, and setting the integrated Intel GPU as the preferred GPU for ALL programs on my computer - still made no difference, I still can't create a Display Capture.

Thanks, I already followed all of those directions - it made no difference.

According to your log, you haven't.

You have an Intel and an Nvidia GPU. You cannot perform display capture on this machine while running OBS on the Nvidia card.

Prior to Windows 10 update 1909, you set this in the Nvidia control panel.

After Windows 10 update 1909, you set this in Windows' display settings.

The log indicates you have not made this change.

 

[Giffyguy]

That's so bizarre.
I literally checked all of this stuff yesterday, including the Windows Graphics settings, which were set to "Power Saving."

I just checked it again, and it had randomly reverted back to "High Performance" this morning, which is why I was still having the problem.
So weird.

I guess my issue is, I haven't dealt with this in over a year, and last time I fixed this I only needed to use NVIDIA Control Panel (now I need to use Windows Graphics settings).

It's working now, thanks guys.

Just a small heads-up @Narcogen, the 'new GPU assignment' method change happened starting in version 1903. The Discord bot had it erroneously listed as 1909 for a while though, but I think they got it fixed. :)

Thanks, I'll make a note of it.
