Center Monitor not using full screen heigth, width

[Sabre]

Hey, ya'll. Put my new gaming rig together last night, and everything's looking good except for one problem. I've got a three-flatpanel set up, with the center screen connected via HDMI cable and the left and right screens connected via display port connectors. The display picture of the two outboard screens extend right to the edge of the display. However, the center screen isn't using the entire monitor real estate.  There's a 1/2-inch boarder all around. Anyone know why this might be? All three monitors are identical, and I've got all three set to the same resolution; the only difference I can see is the type of connection (HDMI, vs display port). If this is expected, how do I fix it? Thanks.

are you using the native resolution of the screens?

look for a setting on your monitor itself called "PC/AV" and switch it to PC.  that should fix it.  it happens to mine to when it's set to AV by default.

Thanks, I'll look at that when I get home, Guncrasher. Is that a physical switch, or a software setting?

Here's your problem in a nutshell

You are trying to run 3 monitors off 1 card which I know with the ATI cards you can. But the problem is you are mixing and matching output sourced. Ie hdmi and Dp which if I remember right have totally different outputs on video. And if I can assume correctly the middle monitor is rendering at the same size as the 2 with the Dp.. Ie 2 outside monitors are showing 1200 X 900 and filling the screen and the middle one is interperting it as 1200 X 900 but with a border, due to different reading fr HDMI.

For eyefinity to work don't all the signals have to be from same source aka DP .... HDMI..so on and so forth???

no it's on the monitor itself.  you know the buttons that it has either in the front or the side.

actually eyefinity has to have at least a single displayport display, as it doesn't have 3 HDMI/VGA 'lanes' built in the the card, only two, if you know what I mean

Just a follow up...I was able to find a setting in the video settings utility for EyeFinity that involved scaling.  The HDMI monitor was set to 10% scaling (translating to a 10% reduction in display size). Setting it to 0% fixed it. Ready to rock-n-roll!

Native resolution is the actual number of pixls built into the hardware. This is the max resolution. For example my 1280x1024 monitor has a native resolution of 1280x1024.

It can display other resolutions, but to do this it "scales" the image to fit the available physical resolution pixels, or it adds a letterbox around the edge.

A google search of your monitor shows its native resolution to be 1920x1080. If you're running your monitors less than that you might get this border you describe. You can adjust your settings and all, to compensate for this. You're looking for the scaling options. However it's probably better to just run at 1920x1080 for all monitors, giving you effectively 5760x1080. I'm pretty sure that video card can handle it.
