I picked up a used dell inspirion 1100 laptop (2003 model) that has XP Home installed. The display shows only one option for screen resolution, 8-bit. I have tried updating and then uninstalling and reinstalling the drivers for the Intel GI, but with no change. I have it set up on a wireless network. The GI is a chipset on the motherbord. Am I correct in thinking that I cannot replace this? Can I go and buy a USB video card and plug it in to correct this, disabling the other onboard one? I called a local computer repair shop and they said they should be able to resolve it for about $45 and that it sounds to them like a software issue, not hardware....... any thoughts ?
