Summary: I got my monitor today and hooked it up. I got a black screen. Nothing else. I undid it and hooked up my 15" monitor and went to the acer website. The CD that comes with it did nothing but flicker inthe drive. I tried tor register it but it said the serial number was wrong, I checked it twice with no luck. I looked for an online manual but couldn't find one. Had a difficult time trying to find out where to e-mail my questions.
