Hello
I just received a new cable box and I have upgraded the UHD722 to V1.08 (latest).
Here is my issue:
- When I connect the cable box to my Pioneer Plasma (15 years old TV) > it works but no sound as I do not have the TV speakers (reason I use the G65)
- When I connect the cable box to UHD722 (input 1 or 2) > I have a black screen with intermittent green flash. I have sound working on the G65
- When I connect the cable box to my xBox One (input in) then xBox One to UHD722 then UHD722 to Plasma > I can see the image of the cable box when going through the xBox One. Picture quality is lower than direct to TV, but I have image and sound, this is what I currently use as a workaround but would like to change that.
Do you know why I have this black screen (green flash) when going from cable box to TV through the UHD722?
What does the xBox One have that allows the image to work through the UHD722?
How can I resolve my issue?

On the cable TV box I have the ability to change the resolution, I move from automatic to 1920 x 1080 P etc. to 720 and still the same issue going through the UHD722
Thank you.
