I have a Roku Premiere 4K and an Xbox One. They both work great, and the Roku acts like the OneGuide on the Xbox. But I’m having one issue: If I turn off the Xbox, when it comes on, it says it lost HDMI signal to the cable box which is the Roku. If I unplug the HDMI from the Roku and plug it back in and it all works perfectly. It doesn’t give me issues any other time, except when I turn on the Xbox. I can watch it for hours and it will not flicker or lose HDMI signal. Any ideas? Could it be because the Roku goes on screensaver mode or something?
