When I turn my Xi6 box and TV off and then on the screen goes from 16:9 ratio filling the screen, to a 4:3 size display in the middle of the screen (with black borders top and bottom like you used to have watching a widescreen movie on a 4:3 tv).
I also lose sound when this happens.
I can fix the problem by going to the display settings, or just by unplugging the HDMI cable and plugging it back in.
not sure how you are turning off the xi6 STB - have you tried turning power save off? power save for an xi6 if in power save for 365 days will save only $1.
I have escalated your issue to the Comcast Team available to these forums. Check back often for a reply in this thread from a Comcast Official Employee.
Hi there, SamB78. Thanks for the post! That is it interesting to hear about the situation with the box. Is this something new that recently started happening?
