I have used the second monitor (Viewsonic 2246m-LED) for the last year as a second monitor to my Acer S7 laptop without a problem. since last week the monitor is being detected by my computer (device manager showing as active) but no image, all I get from the monitor is "without signal" prompt.

I have updated all drivers and reseted both machine and monitor, I even try restoring system to a month ago and no luck. I don't know what else to do, please help!
