Dell Inspiron 8500 laptop, Radeon 7000 Video Card, Windows XP Home SP2. The Video card does not recognize the notebook LCD screen as being connected when booted to the desktop. The FN/F8 key will not switch to the laptop LCD from The attached monitor. Under display settings, the attached LCD Monitor is shown as attached and checked off as the primary monitor as well as extend my desktop to this monitor is checked off. Both these options are greyed out & cannot be unchecked. Device manager shows 4 default monitors. I can boot into safe mode & laptop monitor is then active. I uninstalled the the ATI Video Driver and installed the latest driver posted by Dell, no change. I deleted the 4 default monitors from device manager and uninstalled the video driver and on reboot XP reinstalls the previous settings. I am thinking there must be a registry setting that keeps the attached monitor set as the primary and is keeping it greyed out. If anyone knows how to change this or has any other ideas I would appreciate suggestions.
