Question / Help Screen tearing with sc-512n1-L capture card

[MrGrombles]

Hey folks, recently got myself a streaming machine set up however I am having issues with screen tear on stream and in my obs preview (is fine on the gaming machine). Have tried a few different settings, resolutions and such, but to no avail as of yet. If anyone is able to provide any insight into what may be the cause that would be fantastic!

Should clarify my outputs on the GPU! Display port goes to my monitor and an Hdmi output to the capture card, am outputting at 60hz from the gaming machine (although the monitor is a 144Hz one) Have tried the other refresh rates available to me with no avail.

Obvious question, are you playing the game with vsync on? If not, try switching it on.

I have tried with it both off and on, yet the issue persists. I believe I have the right capture resolution setup and no down scaling option for 720p. Keep tweaking with various settings but no luck yet.
