Hello,
I’ve have an issue with topic said resolution, playing on 11520x2160 fullscreen or windowed/borderless fullscreen cuts around 1/8th of the screen to the right side of the displays.
Playing on a three display setup while in NVidia surround mode.
The only option to fix it is to downgrade res into 5760x1080 fullscreen, or set desktop resolution into 5760x1080 and after that windowed/borderless fulscreen starts to work.
Any combination of in game 11520x2160 res, on Nvidia surround, does not work properly as of right now on my setup.
Regards
