Default Pix Shape Question - Sanyo DP46849

I just got a Sanyo DP46849 and I cannot figure out the "pix shape" I am supposed to be using. I am using the HDMI input for a Blu-ray/DVD player (no TV/cable). The picture looks best in pix 6 or 7 (looks the same), but the manual says pix 6 or 7 are setup as pix 1-2 in PC mode and use of pix 6-7 in TV mode is not recommended.

The picture is distorted (pressed tight in pix 1 and stretched too tall in pix 2-5. A 1.85 to 1 movie will have no black bars at the bottom/top in pix 2-5, which it should since the TV is 1.77 to 1. Pix shapes 6 or 7, which are not recommend for TV mode, will have the slight bars.

Anyone else have this or another Sanyo? Can using this pix 6-7 damage the TV? What are the pix 1-7 settings? Which one should I be using?

(I have only been watching standard DVD's because I do not not have any blu-rays, yet.)

I've not perused the manual for your display but if there is a setting for 1 to 1 pixel mapping, use it. Always.

I'd be curious to know too. I'm experiencing the exact same thing with my 42" Sanyo. I don't get why the manual says pix shapes 6-7 aren't recommended in TV mode with no other explanation than that they are used as 1-2 in PC mode (?!?). As far as I can tell it should only affect the picture shape and nothing else, so why would it hurt the TV? I may call Sanyo if I get some time in the next few days, but there is no 1:1 pixel size setting. Pix shapes 6-7 are perfect though for me. Any help?

If you have a test disk, use a pattern that measures "over-scan" and set the user controls where the pattern shows no over-scan.

The only issue may arise with a transmission fault from a source (cable, sat or OTA) that begins with the guys in the control room of the broadcast. The anomaly will be seen as a line or two of data on any "side" of the screen and will appear as fuzz, lines or dashes. Using the over-scan control to up the over-san a percent or two will alleviate this issue. The VBI will be removed doing this.

On film material, use the 0% over-scan setting.

I have the DP52440 and the same questions about Pix6-7. I have just sent an email to Sanyo customer support asking for more explanation. Will post the response if/when I get one.
