You need to run OBS on the Intel GPU to use display capture.

There is a forum sticky on this subject:

Laptop? Black screen when capturing? Read here first.

I have the same issue, I read the above post on black screen when capturing but it didn't contain instructions on how to resolve. I am running windows 10, intel corei5 8th gen. I don't know how to access the GPU to update - please advise.

You need to disable hardware acceleration in chrome in order to be able to window capture it.

 

[valderson]

You need to disable hardware acceleration in chrome in order to be able to window capture it.

Thank you so much Harold. I did that, but it didn't help the issue :/

 

[Harold]

Remove and re-add the source after disabling chrome's hardware acceleration AND completely restarting chrome.

 

[valderson]

Now we're cooking with gas! That worked, thank you!

 

[Mark Weiss]

This problem started up newly for me, presumably after OBS updated itself. An older version I was running could capture Chrome browser screens with no issues. Since the update, all my browser windows and some other programs like VLC are black. Seems to be a bug introduced in the latest version of OBS.

 

[Harold]

Then your issue is not the same because this thread is over 8 months old.

 

[Mark Weiss]

What I've noticed is that if I capture the entire desktop, the browsers are visible. If I window capture just a browser, it is black.
