Do you have a DVI connector on your current graphics card, or just the old style VGA connector? Pretty much all modern widescreen monitors will have a DVI connector as well as the legacy VGA. If you don't know what those are, see this page: https://en.wikipedia.org/wiki/File:DVI_Connector_Types.svg Most DVI monitor cables have a DVI-D dual link plug on them, but anything matching those patterns is proof positive of DVI. VGA connectors looks like this: https://en.wikipedia.org/wiki/File:Vga-cable.jpg Anyhow, the point is if you're using a DVI connector, X will be able to query the monitor and find out its preferred resolution etc. automatically. Whereas with a VGA connector, it will default to using one of the standard VGA series of resolutions. All monitors will support some sort of VGA resolution for backwards compatibility -- typically 1024x768@60Hz -- and many will support higher, but all of the VGA series resolutions are 4:3 aspect ratio which doesn't look very nice on a widescreen monitor. There's two ways to fix the problem. 1) Get a video card with a DVI connector, or at least a DVI-to-DVI monitor cable if your card already has that. Apart from the hassle of getting a new video card that will work happily with X, this should be pretty painfree. 2) Edit your Xorg.conf to add a custom mode that matches what your monitor expects. Back in the days of CRTs this was a potentially risky thing to do, as configuring the video mode wrongly could phsically damage your monitor. Modern flatscreens however will just put up a message saying the input is incompatible. Working out what the right parameters are to put in the mode definition is the tricky bit. You may be able to use xrandr to pull them out (but if xrandr could do it, then X would do it automatically too...) There should be documentation that comes with the monitor, or you may find a kind soul online with the same make and model of monitor who will send you some xrandr output.
