I use DVI is my computer main screen, and VGA use for my Xbox.
Then I press WINDOWS+P, and select output display option e.g.
From VGA to DVI input but problem its back again first position, so I could not set VGA as screen 2?
Cannot use external display option?
This problem may caused by various way.
1st: Look at the keyboard on your notebook. If you see an LCD/CRT printed on it or maybe a monitor printed on it. It is usually an "F" key. It is usually works Fn+F7. Connect your external monitor and then press these 2 button.
2nd: If you can not find the solve , then you must check some driver like graphics card video driver, Hot key driver, Fn/F7 presentation director and Power Manager Driver.
3rd: If you see the problem again then right click on your desktop and click on Adapter or Graphics Properties and choose cloning. Then keep clicking the Fn+F7 keys 1-3 times until your external will come up.
If won't then your videos graphics adapter might have gotten damaged somehow while running some program.
