the monitor to communicate at the resolution, especianlly in the early versions of the OS.
Change the resolution once in each split screen as described below and click the OK
button. After that, the monitor automatically recognizes and changes the resolution.

bottom margin on the split screen, right-click on the
desktop and click Display Settings.
