That really hurts in a dark room even though I don't have the lights out. Especially 40. It is brutal.
The recommendation for peak output is coming from published documents but it's for studio monitors that the viewer is sitting at the recommended viewing distance.
In HT enviroment, things are complicated, it has to do with viewing distance/screen size/ room conditions/ walls color, and display technology.
There is no rule of what pattern size you have to measure for the plasma peak white, 6.5/10/18% Sized window?
For Plasma you don't have to follow this rule since a 10% sized window will give you 120cd/m2 , 6.5% will give you ~140cd/2, 18% will give you ~100%, but with the same setting the full field will measure ~50cd/2 or lower.
For example Cinetal was recommending 25% sized Windows for Panasonic Plasmas to their DAVIO workflow documents.
As far as I know, the post production monitors/projectors are using field field patterns to set peak white.
Plasma is excluding from this rule, try to get the max outputfrom your plasma without any color channel clipping and watch some movies to see if it hearts your eyes. You will have the max contrast which mean more image 'pop'.
Peak output/ Contrast Ratio of Plasmas is floating... it was to do with contents APL, 1.77:1 or 2.35:1 aspect ratio, generally you will get better contrast by viewing a 1.77:1 movie from a 2.35:1 movie... due to our known plasma design.
