We have several Lenovo X1 Carbon 3444s that are connected to an external monitor (various makes, but HP Compaq LA2405x is the most common) and experience a mouse & keyboard lag. When the external monitor is not connected, everything works perfectly.
What I've Done (but didn't work)
I've installed the most recent graphics driver
Replaced cables (DVI, display port)
Removed the docking station (Targus SuperSpeed Dual Video Dock Station)
Used different keyboards/mouses
Any other recommendations? Thanks!
