Bug Report second monitor not supported with Display Capture

[Derick Bailey]

Hi,

I run OBS on my 2017 Macbook Pro (and previously on my 2012 Macbook Pro Retina) and stream PS4 games using PS4 Remote Play app. To do this, I set up OBS with Display Capture and crop it to the PS4 Remote window.

If I am running directly on my laptop, and only my laptop, it works great.

If I am running on an external monitor, and only my external monitor (with my laptop lid closed), it works great.

Where things go wrong is when I use both my laptop monitor and external monitor.

With both my laptop and external monitor running, I can only use OBS and the Remote Play app from my laptop monitor. I cannot put either of them on my external monitor.

When I try to put the Remote Play app on the external monitor, OBS attempts to pick up the window but it grabs the cropped screen space from my laptop monitor instead.

When I put OBS on my external monitor and put Remote Play app on my laptop monitor, OBS gives me glitches and static lines where the Remote Play app should be displayed.

I would LOVE to be able to use both monitors with OBS! I want to have OBS running on the Laptop monitor with the Remote Play app on my external monitor. That would be an awesome setup. But I can't right now, due to these issues.

Any chance this can be fixed?

Thanks!

Does this happen if you just try to capture the entire display? Or only with "display cropped to window" selected?

good question... had not tested that, previously. here's the results:

capturing the second display on it's own appears to work fine:

the app i'm attemping to crop it to is that gray square - the PS4 Remote Play app. when I crop the window to that, it shows this:

it looks like it's cropping to the right size, but it's offset to the bottom of the window, so it grabs the desktop background instead of the actual window that i'm trying to capture.

this is on a 27" Apple Thunderbolt monitor, by the way... i wonder if the difference in resolution between the laptop and the thunderbolt monitor might have something to do with it? perhaps it's getting the offset from the laptop monitor by accident? don't know really - but it's not working right, that's for sure.

Does that also happen if you add a manual crop filter to the display capture source, instead of trying Crop to Window? I think it's having difficulty figuring out cropping to the window on the other display.

manual crop appears to work fine.

i didn't bother getting it perfect, since this was just to see whether it works or not. but it works as expected on the second monitor.

FWIW - I just submitted a pull request to potentially fix this. it appears to be working for me, at least. hope it helps. :)

HI guys, I know this is an oldie, but I am having this right now. I checked the link for the fix, but as a new user I wouldn't know what to do with it and I'm not sure it still works in 2020.

I can manually crop on my second screen, but as soon as I try Crop To Window (which makes it a lot easier to share windows, because Capture Window itself is a bit sluggish on my iMac.

Anyone else have this problem?
