So I’m not sure if it was just one of these or both (and I’m afraid to undo any of it lest it stop working lol) but:
- I bought an active DP to HDMI adapter (since I had no clue if mine was passive, it didn’t seem to matter using that or my HDMI port directly), and
- I switched my capture card (4K60 Pro Mk.2) to using an internal EDID at 1080p, instead of merged EDID at default settings
And the tearing seems to be gone now! I hope it stays gone. Thank you very much for the help!
(Before that, I had set Vsync in my NVIDIA settings and my capture card as main monitor, both to no avail. So I’m thinking it’s one of the two above that did it for me)
