Sorry to inform you that, there were no such incompatible issues reported with Display Drivers after installing McAfee. However, it would be great if you could let us know the (manufacturer/version) details of your computer's display adapter. In addition to that, try to reinstall McAfee and let us know if it causes the same issue again
Actually, now it appears the driver conflict may be with the most recent 'update' for Windows Vista. If I roll my system back to 9/26/10, everything works perfectly; but I do have McAfee off...
