I have a dual monitor system, both are the x223w. Same problem but only on the second monitor. Backlight shuts off.On/off light stays blue. I have to turn off the monitor and turn it back on. I returned it and Acer could not find any problem so I got it back. No problem for awhile and now a few times over the past couple days. Not good...
