I'm very interesting in buying this LCD, but I'd like to ask ... how is the picture quality when viewing over the air HDTV signals (or any HDTV for that matter). I know the 24" is fully HDTV compatible, how about the different resolution of the 20"? Does anyone know how they convert the signal? Also I know the Dell supports PIP ... what are the options when viewing TV? Also if I'm viewing HDTV, is the aspect ratio of the smaller picture changed to reflect the widescreen aspect? Many thanks for those that have the LCD and an HDTV signal and try out the different options. ^^ -OA PS I know the display features a built in card reader, does that connect to the computer via USB? Is there an in display option to view the images on the card as a slide show? I know several Sony TVs that have that extra option.
