I have this 5-port HDMI switcher: https://www.amazon.com/gp/product/B07CF793HQ
Based on its specifications, it appears it should work with the 2020 Roku Ultra just fine. However, if I connect the Roku to it, all I get is a blank screen and no output. This same 5-port switch works fine with my 2019 Roku Ultra that I have on a different television. Is there any obvious reason why the 2020 Roku Ultra fails to work with this switch?
