Guess ill be checking against store models the next few days but it seems like theres a quarter to half an inch of "dead" space between the bezel and the actual lit up pixels - this normal?

Normal for a Panasonic. This is for when you have the pixel orbiter enabled. The picture will move around, although you won't be able to tell.

It's not dead space, it's just a masking to hide the very edge of the panel. You're still getting the whole image displayed on your screen so you're not missing anything.

And FWIW, some Panasonics do not have this masking and the image extends right up to the edge of the bezel, but most do have this mask.

when they mention 60.1" diagonal measurement - does that not include this mask? Turning off Pixel Orbiter doesnt seem to make this mask disappear.

I have a Panasonic 65VT50. With the pixel orbiter turned off and Size 2 (no over-scan 1:1 Pixel mapping.) I have some dead space on the top and bottom that look like 5 or 6 rows of dead pixels. I made sure to check it with the over-scan test on the Disney WOW Blu ray and everything seems perfect. I figure it's just from manufacturing where they apply the wires and phosphors to the screen in longer sheets of glass and this is a buffer area where they cut the large sheets into TV size sheets of glass. If you are concerned with this as I was put an over-scan pattern on it.

The Disney WOW Disc has a black and white dashed line 1 pixel thick with mark offs for FULL, 1%, 2%, 3% and so on. Very easy to see what the over-scan is.

With 1:1 pixel mapping, if there were actually rows of dead pixels the FULL dashed line would be off the edge of the screen. As it is, it is right on the very edge like it should be. Hope this helps.

this is all new to me - but size 2 seems to shrink the size of the display by a noticeable amount ...is it worth losing that much area for 1:1 pixel mapping?

Disney WoW disk? World of Wonder?

EDIT: Nm - Size 2 shrinks the image when connected to my PC..which is weird..so i set it to Size 2 and scale it a bit to take the rest of the panel. When connected to my PS3 this behavior doesnt happen.

Just to be clear, HD Size 2 doesn't "shrink" the image - it actually gives 1:1 pixel mapping so you get the full 1920x1080 resolution which completely and properly fills the screen. If you find the image is not full size with HD Size 2 then the issue/problem is with the signal that you're sending to the TV. HD Size 1 zooms the image a little resulting in 5% overscan which cuts off a little of the image on all four sides.

When I hooked up my computer to my TV through HDMI, it didn't work correctly with the over-scan pattern. When set to 1:1 pixel mapping (Size 2) I had to use my Bluray player to be sure. I wouldn't trust your computer to be able to test this correctly. Panasonic states in the manual for my TV that the HDMI input may not work correcly with a computer hooked up to it. The signal can be ever so slightly different and it skewed the picture to one side or the other or it's to small or too big. ymmv

I have the Disney World of Wonder Bluray Disc There are a couple different versions. The release date for mine is April 3, 2012. There are other discs that have a similar test but this just happens to be the one that I use.
