U2711, HDMI, issues
More recently, when I wake up my computer from sleep, I see an image like below on my monitor. There are also cases where one side is solid blue and vertical stripes appear on the other. What could be the cause of the error? I look forward to your help and answers.

* Run the stand alone U2711 Self-Test (page 39). Do you see the issue there?
* Test a different HDMI to HDMI cable
* Test the U2711 on a different PC HDMI out port
* Test the other U2711 video in ports (DisplayPort/DVI1/DVI2/VGA) from multiple PC
