Afict, this is an oft-reported problem that Win11 has solved with a specific setting which does not exist in Win10. The DP is running off a Thuderbolt 4 dock connected to a Lenovo laptop. Thought I'd check here before giving up. (A recent upgrade to Win11 on another comp went so badly that's not a solution.) Thanks.
