I have triple monitors on my pc .Two are working but the third just has a blank screen even though the power light is flashing on and off.It's probably the monitor itself so may need a new one .But I was wondering (before I buy a new one!)if anyone else had encountered this problem.
Also go through the monitor's own menus via the switches on the monitor itself, in case you have accidentally set it to take input from a different source from the one plugged in (or even have turned the brightness right down).
From the pc, make sure it is set up to send to three monitors.
Check the cables are plugged in and working.
