Summary: Like several other reviewers here, I have had the same problem with this monitor. Purchased two years ago, recently started showing a blank screen with the power light flickering on and off with no image on the display. Like others, I was lured in by the excellent specs...this is real disappointing because Viewsonic is a manufacturer with a good reputation.
Summary: I bought the monitor as a gift for my son. I set it up, it looked great. Walked out of the room and came back in a few minutes to a black screen. Turning the monitor off and back on gets a screen for only a few seconds. Tried it on another computer - same result. I used the on line support from viewsonic. They wanted me to access the menu but this was not possible. I was advised to return it for a replacement.
