OTA HD will likely look better than the HD that is piped in from your provider, so enjoy it while it lasts!!!!!
Very nice picture right out of the box. Been trying to find some suggested settings online, but no luck so far. It has a Picture Wizard I'll have to try.
There used to be a DVD called AVIA that one would use to calibrate their TV. Now their is a blu-ray version for HD. I'm not sure what it's called, if it's still AVIA or something else, as I don't keep up with AV as much as I used to.
You can also search your TV model on AVS and a lot of times there will be a post where guys have used the calibration DVD and then post their settings. Or, guys will post the settings they like after jacking around with it for months.
