I know i'm digging threads here and the TV is getting to be a few years old, but i though't i'd post the results of my own panel of what can be achieved with only the user-menu settings. Before i delve into the Service menu to try and get it spot on.
NOTE: my TV is a non-THX certified 46-PZ800A

Results are using an i1Display2
this has only been calibrated as beast as possible with the THX Disc and Blue filter glasses.

these are the results from the Normal Mode with Normal Colour Temp
Using HCFR and the HCFR Test Patterns (lucky i know a little French.) and using the Curtpalme Greyscale for dummies guide.
I have results for the Cinema mode, Colours track exactly the same, but with even lower gamma in the low end.

Contrast is only on 80 and it's pumping out 63.2FtL of peak brightness (217cd/m3) NOTE: (Comfortable Daytime setting, no adverse picture effects evident)
and a Black Level of 0.019FtL (0.07cd/m3)
Average Gamma of 2.15

Gamma not tracking too bad, but a little low in the low end (I assume due to the high level of peak brightness??)


Luminance levels track well


Colour Temp is a little cool, but looks a heap nicer than excessively warm

and we can see why it's a little cool, too much blue and not enough red


Most DeltaE's are all pretty consistent around 10-13 with a couple further out


so at least i have a place to start to at least get the greyscale colouring correct.

My DVD player does have it's own built in 10point gamma correction so once i have the greyscale right i can then look at getting the gamma spot on for my highPQ source.
for my DVR i have MP4 versions of the calibration images so can get that input as close as possible, but with a compromised gamma, however, the quality of the recordings are usually of lower quality and unknown origins, so they're compromised from the begining

I'm going to do a complete reset to see how bad it's out of the box presets actually are... horrid i assume

I'll be interested to see what effect getting the colours spot on has on the Gamma curve, maybe none?
but i'll experiment and see what becomes of it.

Digging up an old thread, I miss my 50PZ800U, it had great PQ, lost in the divorce, I have since bought 2 other Panny Plasma TV both 50's but don't have the model numbers with me. The first one I bought was around the end on 2010 and does not have fans like the PZ800U, the second one I bought around the end of 13, it has Wifi, and DLNA that I love. The PQ on both units is very good, but I had to go over and help my son with something at the ex's house and seen the PZ800U and could tell a difference :-( Hmmm, wonder if she needs money, she might sell it to me, LOL

Where are you located?
I have that 50" and lost the 58" of same in my divorce.

I've moved on to an 80" LCD and the 50 was delegated to bedroom duty and actually hasn't been used for several months.
Nice TV
