XB273UF after wake up goes split screen mode.

Hello, I did the ULMB 2 firmware update on my 360HZ monitor and sometimes usually the monitor will turn off for sleep from windows settings then upon wake up the screen will be split with 2 different color profiles on each side left side being overly bright. I recall reading about this from the firmware update. Unplugging the monitor or using Ctrl+Shift+ Windows+ B works as well. But why does this keep happening?
