Lenovo Docking Station VGA Monito Issue

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.

Any suggestions?

Check any powersaving options and disable them.

I probably should have been more clear explaining what I experience. It does not turn off the VGA Display totally. I can still see a little at the top of the screen and it is flashing and jumping. 90% of the screen is black and the rest is flickering showing what was just there. It is very hard to explain exactly what it looks like in words. The picture just gets messed up as if the feed got jumbled. If I could take a screenshot I would, but I cannot.
FYI - All power settings were already set to Maximum Performance and power saving are all turned off

There are no Firmware updates for this model Docking Station.
All of our power supplies are the same for the Laptops themselves and the Docking Stations.
I don't think we plan on ordering different power supplies even if they are offered.
