I have only 1080p TV connected to my PC so I normally have my desktop set to 1080p. I set all the custom resolutions in Nvidia settings and they work fine in all other games but RDR2 just won’t let me chose any resolution higher than my desktop resolution so I have to change it every time if i want to play.
Is there any good way to force the higher resolution in game? Some txt. file or arguments maybe?
For me it works as normal in rdr2. Try changing between Fullscreen or windowed mode, often the borderless/windowed modes restrict to the displays native.
