I have only had my Samsung 750 for 1 week so far, having ordered it from Amazon. I am connected to AT&T UVerse cable service. I am qiute happy so far and am gradually trying to learn about all of the available settings. My immediate question has to do with the Picture Size adjustment under Picture Options. It lists the following: 16:9, Zoom 1, Zoom 2, Wide Fit, 4:3 and Just Scan. However I can't activate either Wide Fit or Just Scan. The titles appear in a light grey color and when I try to scroll down from Zoom 2 it skips over Wide Fit, and the same happens when I scroll down from 4:3- it skips over Just Fit and goes to 16:9. Can anyone tell me what is happening and what I need to do to be able to access Wide Fit and Just Scan?
