I sure hope you can help me with this because it is driving me crazy.
I just built a new computer with:
- ATI HD 5670 video card
- Samsung S23A350H (with HDMI and VGA inputs)
If I plug the monitor into the video card using the VGA connection, the picture displays razor sharp at 1920 x 1080 resolution and fills the screen perfectly.
If I plug the monitor into either the DVI or HDMI connection on the video card and then into the HDMI connection on the monitor, the picture doesn't fill the screen --- it has a BLACK BAND around the outside of the picture about 1/2" wide all around. It does this whether I use the DVI or HDMI connection on the video card.
If I go into the ATI Catalyst Control Center software (version 11.5), it indicates that the output is HDMI 1080p. My thought was to switch back to the Basic Setting instead of HDMI, but it doesn't have an option for 1920 x 1080 resolution.
I have no idea what is going on here. When I used dual 23" monitors with a cheap ATI video card on a Dell Optiplex computer, it worked perfectly.
