Just bought Samsung UN46B7000 the other day connecting to HDMI (Rocketfish 1080p/ 120Hz) to Cisco Explorer 8640HDC Cable Box supplied by Time Warner.
I will watch 1080i (1920x1080i@60Hz) perfectly fine looks great on ESPNHD. Then I turn off everything and turn back on it automatically switches to 480p (720x480@60Hz) without me touching A THING! Like it has a mind of its own.
On the cable box I checked the settings and only have 1080i selected. But it still outputs at 480p everytime I turn off and turn back on.
I have to go back and select all outputs and deselect them to "trick" the box so it will switch over to 1080i. HELP!!! Thanks!
