Hi, I recently got a new Dell desktop with a 21.5" HD monitor set to to 1920x1080 (recommended) with ATI Radeon HD 5670 1GB GDDR5 video card. I have already connected my 46" HDTV to the desktop as a secondary monitor for watching movies. My problem is when I set the TV resolution to 1920x1080 in my PC desktop property, I will have an 1" black gap on all 4 sides of my TV screen, and the only way I can have the full view on the TV is to set the resolution for the TV to something lower, but then the text would become pixeletted. I really want to have the resolution to be set at 1920x1080 for both the monitor and the tv. I've called Dell support and they said that my video card is not supported to do that. Is this true? It's hard to believe. Is there a place where I can adjust or stretch it? Thanks!
