I have a rather strange problem with my monitor setup at the moment. I have an HP Z Book with Windows 10 (20H2 still) from work. When working from home I use an Sitecom multiport adapter to connect 2 external monitors via HDMI. Since my workspace is limited, my laptop is closed on my desk. So I only use the external monitors.
Sometimes, my monitors loose connection. Specially when browsing to a website that is showing video. Not all the time, but sometimes. I tried with different browsers already to see if that is the issue. But happens with Edge, Brave and Chrome. To give an example, when I go to Netflix with any of these browser I usually get the issue when starting a video. The problem does not occur when I use the Windows 10 app for Netflix. So that makes me think it's related to the browser.
The problem however does not occur when I have my laptop open. That's the setup I use when going to work. Never had any issues there. But I use an HP docking at work. Has anybody seen this behaviour before? I'm not sure how to debug this problem
