I have a 27" CRT HDTV (Panasonic), with a a native resolution of 1080i.When I plug in my HTPC via a DVI to HDMI cable using the 1920x1080 resolution on my Nvidia 6150 video card the displayed image has black bars on the top and bottom. If I press the aspect ratio button the remote nothing happens. However if the computer is not plugged in the aspect ratio button does change between 16:9 and 4:3 on all video sources on the TV. Is there a way to force full screen with the HTPC plugged in? Or will changing my video card make a difference? THANX!
