DO NO buy Acer monitors... Their support technicians are useless when it come to fixing the monitor issue with no power on and Acer logo flashing during initial turn on the monitor power. Two seperated cases was openned for each of the problem mentioned earlier. Sent both monitors to Acer for repair and got back with exact same problem. There is no way to convince Acer tech support that their monitors are defective and should have been repaired or replaced instead of sending back and forth for nothing. DO NOT BUY ACER MONITORS - their warranty is sting and useless when you need your monitor service under warranty. read full review »
