I have a comcast RNG100N Cable set-top box from Comcast. When I hook it up to the Xbox One for HDMI pass-thru it does not work and constantly shows "We've lost your TV signal". When I first had the console and tried to hook it up, it was mostly a black screen with this message on and off, however now its constant.
I have tried several HDMI cords to go from the cablebox to the Xbox One including the cable from the Xbox One with no luck. However, if I hook up my old Xbox 360 to the Xbox One's HDMI pass thru, it displays a signal perfectly fine, infact I playedf GTA 5 for over ab hour like that with barley noticable lag,
I have tried to enable Power Saving as some users have said and plugging the TV's HDMI cable into the Xbox One's passthru with the Xbox One off and still have no luck. With time I learned how to change the channels source from 1080i to 720p and i still have yet to get it to work, or even show a picture of some sort.
I have also tried to boot the cable box from a cold boot to ensure it wasnt something small and simple, however, still no luck.
Has anyone else had this same issue and got it to work?
