HP Compaq nc6320 PC Notebook Resolution Problem

Hi, Your laptop uses the Intel Graphics Media Accelerator 950 video engine, when you installed XP SP2, Microsoft installed its own version of the latest drivers. Perhaps you can try using the manufacturer's driver and not MS. Go to Intel website and download their drivers. (http://www.intel.com/products/chipsets/gma950/index.htm) Of course you have to create a restore point so that you can roll back in case if does not do the job. On some config/install I've done in the past, an older version of the drivers works better than the latest. At other times, the motherboard's AGP port and chipset (specially Intel) have likewise to be installed. Good luck and kind regards.

The hardest problem with labtops is finding what exactly what kind of video card is in there. You need to check all documents you receieved with your computer. If you right click my computer and hit properties, hardware tab, device manager. Look under display adaptors to hopefully find the name of the card, and its manufacturer(Nvidia, or Radeon). Look up the manufacturer like (Nvidia, or Radeon) on the web. And check for new drivers.) If its clear on one resolution, thats pretty much proof that there is nothing physically wrong with the monitor, so that leaves the drivers.
