My laptop is connected to an external monitor via a dock. When I look at the external monitor, there are random light colored flashing pixels jumping all over.
I can't connect the monitor directly to the laptop because I don't have the proper adapter.
In addition, the display goes completely black for a second at random intervals.
ThinkPad W541 with Nvidia K2100M Graphics (but I think the monitor could be running on integrated graphics, idk) and the standard Lenovo dock for this line of laptops.
The monitor is an Acer G276ML.

Thanks for any advice!
