Am running Win 7 on recent HP (out of War.) with 23" HP video. The video has recently started to 'flutter' at a very fast rate at which time the brightness of the screen decreases by about 50%. It happens without notice, stops with same, may start at startup or at any time and then may return to normal at any time. No attempts at correction seem to help!!!
