I was adjusting the brightness of my monitor, i brought it down to the lowest setting and when i exited the menu my screen went blank. I figured I just brought the brightness down to low and resetting to the factory defaults would help. ( I had to do this blindly, with the help of the manual, since i couldn't see the screen) after several attempts at pressing menu, the arrow keys, then turning off and on the monitor, it worked and i could see my screen. I went back into the menu to make sure my brightness was back to 100% and it was. However, whenever I turn off my monitor and turn it back on, it flashes "acer" for a split second, then flashes my windows screen for a split second, then goes blank. I always get it working agian after SEVERAL variations of menu, arrows and turn off and ons, (I believe it is actually the repeated on and offs that fix it, not the menu buton variations). I prefer not to send it back to Acer to get repaired unless absolutely necessary.
