Question posted by shariwm on December 4th, 2010
Tv Resolution Issue -- Only Get Certain Channels...
We subscribe to HD cable TV. It puts out 480, 720 and 1080 resolutions. We use HDMI cable from box to TV. Some channels are different resolutions then others and we are unable to access all channels. The box works on other TVs, so we know it's not the box. How do we get the TV to automatically adjust to the box resolution?
