waltaz, you should know better than to listen to a cable guy in regards to hidef...
You should really use the HDMI connection. You want bit per bit perfect transfer of information between the source and your TV. Even with 1080i content, you want the TV to get the information digitally. I would think there would be more lag with the TV converting the analog signal into digital.
As to the calibration. I am liking the picture better with backlight high and contrast (relatively low). I see that others have backlight low and contrast high. I am guessing that is because my TV is in my family room where there is a lot of ambient light and most of the settings are from guys with a dedicated HT room.
Anyone else who likes backlight higher?
