Picture was fine when connecting via HDMI.</P><P>Our IT team upgraded to RoomOS 11.30, which seemed to address the issue of picture quality over USB.&nbsp;</P> Tue, 15 Jul 2025 22:43:14 GMT https://community.cisco.com/t5/webex-devices/using-a-desk-pro-as-an-external-4k-usb-c-monitor/m-p/5309778#M2064 ginoti 2025-07-15T22:43:14Z
