I have a Dell Latitude CPx. It had crashed and I replaced the motherboard. P3 500 MHz WinXP Home. It has an ATI RageMI video controller and 14" panel. The image appears as if it is a 12" panel, anchored to the top left corner. The bottom of the panel begins a repeat of the screen and the right side stretches to the edge. This occurs as soon as the machine is powered up, including during the boot process. I have tried changing the display settings in Windows and it has not helped. I do not believe it is a Windows problem. This is not going to be a technically correct description, but it's the best I can do. It appears to me that the motherboard thinks it has a 12" panel and displays correctly for that size. Then the left over portion of the panel makes up an image that corresponds with what is being displayed. How do I make it realize it has a 14" panel?
