I am trying to hook my visio vw32l flat screen tv to my Acer aspire one via a vga cord from the pc to the tv. I start with both units turned off and the cable hooked up. Turn both on. As the computer boots up it displays perfectly on the tv. Up in the corner it says 800x600. When the windows operating screen appears on the computer, the tv goesw blank except for a message saying "no rgb signal and tv will be turned off" The computer guy at walmart said to turn down the resolution on the omputer so I set it at 800x600 because i know that works on the tv, but no change. As soon as the windows starts, my signal is gone. Any idea what is wrong? Email Removed]
