Wajo, I looked around info for your TV (Vizio GV47L 47" 1080P), I found an interesting fact. It does overscan in all i/p except for 1080p.
I didn't find any reference to Gamma Correction though.
Can you please do the following observaiton
- Set TV to HDMI, Set 3575 to 1080p YCbCr: Is the picture on TV clipped in from (I do not expect it to be clipped).
- Set TV to HDMI, Set 3575 to 720p YCbCr: Is the picture on TV clipped in from (I expect it to be clipped). Also is there any difference in picture darkness with that of 1080p.
Don't have a TV setting for DVI, but I did ratchet thru the 4 HDMI output modes on my 47" 1080p LCD's HDMI-1 connection and saw an interesting "shift."
I tuned to my fav test channel, QVC, which keeps a banner at the bottom of the screen long enough to make position comparisons.
Going from HDMI 480p to 720p made only a very slight change in position of the bottom-left corner of the banner (barely noticeable), but going to 1080i moved that corner of the banner up and right ~3/4", and going to 1080p moved that corner further right ~3/4" more but about the same pos up as 1080i. (Distances could have been anywhere from 1/2" to 1", didn't measure.)
I had to do this during a break in my CFO/wife's Soap watching timeshift, and she told me to tell everyone, "You're all crazy, driving yourself nuts over a tiny little difference... it looks good so just leave it alone!" or something along those lines.
My 480p *MIGHT* look brighter than 1080p... VERY little diff. in brightness and really hard to say there was any. My CFO/wife just said, "ehhh"... but then she thinks we're full-o-****zu anyway!
We both thought 480p was slightly but noticeably sharper than other modes.
