Hi, i've just got a 32" Toshiba 1080P LCD TV and I tried using VGA to get 1080P - no luck. I just tried a HDMI Cable with a DVI to HDMI adapter and it works but the picture is oversampled and I only see the middle part of the screen, do I need to change my graphics card to one with a native HDMI output rather than a graphics card with a DVI output and a adapter?
