Why won't my resolution adjust when I use an external monitor with my laptop?

Episode 1072 (28:14)

Gary from Los Angeles, CA

Gary notices that his resolution doesn't adjust when he docks his laptop to his monitor. Leo says that's odd because Windows should do that really well. Chances are, this is an issue with the Lenovo laptop. Ideally, Gary will want the monitor to display at the native dot for dot resolution.

The chatroom says using DisplayFusion is a possible solution and they have a "try before you buy" download. UltraMon is another option. He should also make sure he has all the latest drivers. Leo suggests using "mirrored," not external display.
