Take down the model and serial number of your monitor - google for the technical specifications - then see that the horizontal and Vertical sync numbers set in the monitor section of /etc/X11/xorg.conf are the ranges set forth in the specifications. 2. Check the horizontal and vertical position and size controls on the monitor itself. Monitors will change somewhat in different modes and some adjustment may be necessary. 3. If no joy also obtain the technical specifications on your video card, and that you are using the best driver for your video card. Sometimes you can use a live cd which will make a good xorg.conf and find a good driver (see with "lsmod"). Good Hunting! Tod
