Ok so I have had my new monitor for about a month now and every so often I get a brief flash on my screen. I call it a flicker because it happens so quick. I have no idea for the life of me what it is though. It does seem to happen more regularly when playing games but not exclusively.
my monitor is a ASUS VH242H - 23.6" and my graphics card is a GTX 560
