I have a Lenovo Thinkpad l440 with a docking station. I have Dual Monitors. Both are Lenovo 22" ThinkVision. Since the Docking Station does not have Dual Display Ports I am forced to plug in one Display Port and one VGA.
The Issue: Every hour or so the VGA starts to flicker and then is completely unreadable. I have to go in and make them a Clone Display and then change it back to Extended Display. Then an hour later or so the exact same thing happens.
I have updated the Drivers and tried a new VGA cable. I swapped the display port and the VGA on the monitors themselves and the other screen now has the issue. Always with the VGA is the issue.
