So I use a 49" Dell U4919DW (5120 x 1440 @ 60Hz) with an Anker 777 powered Thunderbolt hub to support a MBP, but also use it directly with a lab Windows box. I can't see spending $3k on a monitor because this one was $1100 + $157.29 tax and shipping in 2022. I threw on a 4 port USB-C hub that clamps on the front bezel, so it has reachable ports.

I guess this almost replaces the Anker, but lacks Ethernet.
