I am having problems with my monitor.  In race mode, the crosshair regularly turns on and off. I have tried a full reset, unplug it. Various settings. Even with off in race mode, the crosshair comes on while the computer is doing nothing.
 The colours of the screen also change every now and then. My monitor is 32" QHD monitor, Medion Akoya P53205 which I want to use for editing pictures.
