any updates?  disabling the "Screen Saver" and "Pixel Cleaning" options don't do anything and for me, it seems longer than 6 mins well I disconnect the power and re-connect it as I'm not waiting. and going by all the other people having the same prob...

the screen saver is off and pixel cleaning just does not there is no option other than to run it

Why hasn't Asus said or done anything? Going by a basic goggle search  it's more common then just a few people

Seems i have the sam problem after upgrading to V037 Firmware, after about 4 hours it just goes blankI have to replug the power to DisplayPort (only connection I use on the screen)
