I have overscan issues where I can't see some content because portions of the screen around the border are cutoff. Wondering if there's anything else I might do to fix this issue. One example of the overscan is Foxnews on channel 820 where the lower left hand rotating clock is half-hidden and I can't tell what time it is. Other channels have similar losses around the border. When I switch to 56 which is the FD channel, I see considerably more info with additional space beyond the rotating clock.
The setup is HD via Comcast Explorer STB which is set to 16:9.
The TV was originally set to Picture Size>16 X 9 and I changed it to Picture Size>Screen Fit.
Are there other setting on the STB or the TV I could change to further reduce the overscan?
