I have the Aspire X1200 desktop hooked up to my 46" LCD TV as a media player via HDMI cable. However whenever I use the computer on my TV, the picture will go black intermittently and then after a few seconds come back up and will do this over and over. Ive tried to fix the refresh rate and the resolution, but that doesn't help at all. Does anyone have any other suggestions to fix this? Please Help me.
