Mouse lag when connected to an external display (with MacBook lid closed)
Device information: MacBook Pro (15-inch, 2017)
Mouse information: Logitech G903
Display information: LG 34-inch ultra-wide
System: macOS Big Sur 11.2.3
Problem:
The cursor has a significant lag when I connect my Mac to the external monitor with the lid closed. But the cursor can move smoothly when I connect to the monitor with the lid open. Mouse is connected to my Mac through a USB-C hub, and the monitor is connected via an HDMI cable. Does anyone have a fix on this? Thank you!
