Need help with new monitor

[JPFisher55]

I just bought a Samsung 32" 4k monitor; model LU32J590UQNXZA. It normally runs on px3840 py2160 setting. It seems to run everything great except this game. I am using the last unofficial public beta -1126b patch 07. I can't find a resolution that works in either full screen or windowed mode. The screen will not center and fill up the monitor space no matter what settings I use. I have tried 3840x2160, 2560x1600, 2560x1440, 2048x1536, 1920x1440 and 1920x1200 beside the original 1920x1080 which worked on my old 27" monitor which died on me yesterday. Can anyone help with this new monitor?

Never mind, I figured it out. I have to start in the main directory folder, not the beta2.
