I purchased a SB220Q monitor yesterday for Office work at home. My office computer is a Lenovo 460 with a Lenovo Thinkpad Pro docking station. I am using the Display Port on the docking station to connect to the monitor. I am having an issue where a few times a day the monitor goes black for a few seconds. I notice sometimes that the screen starts to flicker before it goes black. I have tried replacing my "Display Port to HDMI" cord with a HDMIcord and DisplayPort adapter. I am still getting the blackout issue.
