I have a Dell laptop with Windows 7, and use a monster vga cable to connect to my tv so I can watch DVDs. However lately the tv has been pausing/flashing at regular intervals and it gets really annoying since it has been doing this about 50 times during a movie. I've tried messing with the screen resolution and adjusting projector to only display my tv monitor but nothing seems to help. Can anyone help me?
It may be that your cable has a break in it, some TVs will hold the last frame displayed when the signal is lost and this could account for the pauses/flashes. Do you have an old monitor with vga input to test it on?
