MacbookPro 2019 w/Big Sur 11.2.1 problem connecting to BenQ PD2720U via T3. Any suggestions?

I have a Logitech MX Master 3 mouse and a Logickeyboard for photoshop/lightroom attached to a BenQ PD2720U. BenQ is attached to a MBP 2019 via T3. The only way to get this to work is to open the MBP and restart it, then immediately close it. Any thoughts?
