MT223,
Just wanted to follow-up for you. I've fixed my issue by removing the DisplayLink drivers completely from my system.
I have a DisplayPort 1.4/Intel 11th Gen/GTX 1650 Ti in my laptop. The Kensington SD4900P is a DisplayPort 1.3 device.
I've updated to use a Cable Matters DisplayPort 1.4 hub with MST and DSC support. This has allowed me to remove the DisplayLink drivers and have it 'just work' for 2 external 2560x1440 monitors.
Model number for reference is 201331-BLK.

Good luck!
