I had 2 screens but recently i added a 3rd screen and this is when my problem started to appear .My current screen setup:
Main screen : Connected with dvi cable to my video card .
Second screen (used to be main screen before):Connected to video card with hdmi cable.
Third screen : Connected to motherboard with vga cable .
The problem arises when i try to switch to single screen with "PC SCREEN ONLY" because the secondary screen is the one that stays on and the main screen and third screen shut off .
Any solutions to this problem ? Is it a cable problem or a settings one ? Or maybe some drivers need update ?
