Hey @Edocsil2020

Just as the other posts you have made, I am providing this information to the team to try and recreate this and provide a solution to the matter!

Thank you for filling this out so well! Will get back to you soon!

I believe this is a known issue with no fix so far:

Display “Idle to On” transition resets USB Hub - Products / Spectrum ES07D03 | User Experiences - Dough Community

Thank you for providing the link to the existing topic! I will provide you both with more information when I am provided with a possible solution!

That issue is for the USB hub to restart when the monitor resumes from idle but the new issue I have raised is for the USB Hub restarting when changing the source. It only became an issue in fw106 and upwards. Not an issue in fw105. Probably closely linked to the issue of the USB hub restarting when coming out of idle
