T480 Trouble With External Displays on USB-C Gen2 Dock

2019-12-22, 18:42 PM

I'm putting together my desk setup, but having trouble with the external displays.

 

PC: ThinkPad T480 w/ Intel HD Graphics 620

Dock: Lenovo USB-C Dock Gen 2

Display 1: Lenovo ThinkVision P27h-10

Display 2: Lenovo ThinkVision T23i-10

 

I can get the P27 working at full 2560x1440 but when I connect the T23, the image is vibrating for fuzzy. If I adjust the refresh rate, I can get both displays in focus and stable, but the 2560x1440 P27 then drops to 1920x1080 resolution.

 

BIOS update on the ThinkPad? Am I out of luck with this particular combination?

 

Thanks

Patrick
