True, for a full cal you DO want that many hours.

With an Avia disk, etc. you can wing it, go back in a month, tweak some more.
In fact, I usually use a cal disk right away because it helps get the basic settings done with a new set. Takes off that 'showroom' shine. Of course, there are settings at tweaktv, etc. that help there too.
The cal disk is usually a finer tune.

I purchased an Eyeone Pro Color spectrometer, and am calibrating my Panasonic TH58PZ700U display.

In the standard mode, with warm temperature setting, I have no problem getting the grayscale 6500K, RGB, and color temp of 6500, but I'm having a hell of a time getting the luminance and Gamma to fall in line (see below). My display doesn't have designated gamma controls in the User or Service Menus, that I know of.

The picture at times seems too vibrant, could I tone it down in the User menu without screwing up the grayscale?

Is it true that the HCFR program misrepresents 2.2? I heard that 2.2 readings on their program really reflects 2.5, and that 1.9 on their program represents 2.2.

However, if I go to the cinema mode, with normal temp settings, I get:

But the picture seems a little dark.
