OK... Looking for some help, I've seen others have had this issue but I don't see a fix.
I just got a Crystal UHD Samsung TU8000. Not sure how this happened, probably during the setup process. HDMI ONE is Comcast Xfinity for TV... This is correct.... HDMI TWO is Comcast Xfinity which it should not be. I'm trying to add my Google Chromecast device to HDMI TWO. I can not find a way to delete the current source of HDMI TWO - Comcast Xfinity.
