Desk Pro, signal from USB-C flickering

fredrik.olastuen — Wed, 12 Jan 2022 08:33:19 GMT

I was running the beta release of RoomOS 11 for a while on my Desk Pro, but had to roll back as the signal from my laptop, connected through USB-C was flickering every 15th second. Rolled back to the latest RoomOS 10, and everything worked fine again. Now the unit is upgraded to 10.11.1.1 (RoomOS 11) and the problem is back. Anyone else experiencing the same?

I am having the same issue this morning after the software updated to 10.11.1.1 overnight. Please help as I need this device to function properly for multiple calls I am hosting today.

Same problem here since the device has updated to 10.11.1.1 on 12.01.2022

Workaround (of course with functional limitations): use HDMI

I just setup the second screen at 1920x1080@30hertz using the USB C and it has been working for about 30 minutes. Not sure if the flickering will come back but worth the try. Not the best resolution but works for now.

Did an update to RoomOS 10.12.1.4 this morning.
The flickering is gone, Hooray!

Thanks for your replies. After several sessions with testing with the developers at Cisco, they obviously found the bug and solved it. Hooray!

I've got the same problem on Mac and Windows, already changed the cable, reboot all the devices. Could it be a physical issue and how to fix it ?
