I have an Asus laptop. For the last couple of weeks I enjoyed using my notebook monitor as an external monitor on my TV. I have the cables. It worked perfectly. All I had to do was press FN + F8 and the screen would appear on the TV. It was great I could watch my movies on my TV screen.
Suddenly, yesterday when I press the FN + F8 swtich it doesn't
go to the TV. In the past when I pressed it my screen would become dark and appear on the TV. Now all it does is become dark for about 1 second, and then go back to normal. It won't show up on my TV. It is only dark for a split second. The odd thing is when I press FN + F7 which is the LCD screen, my screen becomes dark. But when I do it with f8 which is LCD/TV it is only dark for 1 split second and then back to normal.
i re-booted the notebook a few times. Didn't work. I used system restore to go back a few days, didn't work either. I been looking at forums for advice, nothing seems to help.
Any help would be greatly appeciated!
My fn + f8 TV/LCD switch is not working on my notebook?
You might try reinstalling the drivers for your video card. Sometimes they get corrupted and then Windows will pick a generic one. When it does, it limits its capabilities to basic functionality.
Hope that helps you!
