Have you checked to make sure you have the latest driver? If it's a Sony or HP, you almost might consider updating the BIOS on the computer, which you can find on the manufacturer's site.
I have connected my laptop to my Samsung 32" HDTV( 5 series) via VGA cable. I am getting a perfect display of the computer on my HDTV. But there is this message "check signal cable" which stays in the middle of my TV display and does not go away.The message stays even though I am getting the display of my computer on my TV.
Is it because of the VGA cable I am using or is it because of my video card ( i am using nvidia 8600M GT and windows vista).
Is it possible for me to disable this message "check signal cable" on my TV.
