I recently bought this TV: Samsung TV. I also have a standard definition cable box from Comcast which has a composite output. I realized once I got the new TV that there is no composite input on it so I bought a composite to HDMI converter. The problem is the quality actually seems worse with the converter than with my previous TV, which is an older 720p Panasonic Viera. I would expect it would at least be on par if not better. Do I need to do something with the TV settings to fix the quality? Is there a special way to set it up that I'm missing (it seems pretty straightforward)?
