I recently connected my Gateway computer to my SharpHD TV via HDMI.

However, when I tried to watch my netflix I noticed that in nighttime settings, the dark areas of the screen were patchy and pixelated.

I know this is not a limitation of the TV because I watched the same netflix movie by streaming it through my Nintendo Wii with no problems. I check the display settings on the computer and it matches the suggested ratio for the TV. Is there something else I should be aware of?
