hi , 1.ps press 'windows+p' to Change the display mode, it have 4 display mode ,PC screen only/Duplicate/Extend/Second screen only。 when the display mode is Second screen only,it will only display external monitoring 2.the 4k monitor need to intall a driver to support it, ps double check. 3. update the latest driver of VGA.
