But my projector is 4K capable. If I’m playing uhd Material the output says 3840x2160.
Okay. Do you have DPI scaling in Windows on? I've noticed a persistent conflict between it and MadVR, maybe the same applies to JRVR? (I wouldn't know, I don't use DPI scaling despite probably needing it lmao)
Thank you. That seems to be the problem. Screenresolution in Windows 10 was set to 1920x1080 (because of my pc screen ). Now it works
