hi I just purchased a Samsung T5271F

I have a new HTPC that I buildt running with Vista 64 and a video card ATI HD2900 Pro. I hook it up with HDMI cable

For some reason I cannot get a full screen. I have on each side of the screen a 1inch black space with any resolution 1920x1080 or 1280x720

Please someone help me I called Samsung and AtI no one knows how to solve it.

(I do have full screen with HD channels though)

Thanks for your help
