If u use the same channel logos at high brightness/contrast and not use anything else, there is a chance of course.
Last night, I spent about 3 hours calibrating a 50V20. These are my comments.
The black levles of the set are good. They are in the range of the Pioneer 8G sets. However, there is a caveat. The sets black levels are noisier than the older gens. As such, there is a lot of dithering in the black/shadows. If u r seated a reasonable distance from the set it would not be visible. Becoz of this, the black level does not look visually to match the older 8G Pios.
The Pro1 and Pro2 settings allowed me to hit about 40+ft/L. I managed to shoot 45ft/L but the gamma was all funky. 40ft/L and below is pretty ok.
Gamma tracking is not great. It is always lower in the dark areas while maintaining good tracking above 50%. If u target a gamma of 1.8 the gamma curves look better. Trying to target 2.2 oe 2.3 u get some strange behaviour. However, it would not be noticeable to most. Actually most people would even comment that there is more shadow details but this is not as correct. Greyscale tracking was also not too bad, Delta Es below 3 for the whole range from 10-90%.
Colour accuracy on the set I worked on, was not too bad, I could hit Delta Es of below 3 for all colours. However, it is not reference as yet. I need to see how it can be tweaked when i work on the next set.
This is however, the best Panny plasma I hv worked on in the past few years.
Now the grouses, the problems with 50Hz signals are very evident. I could reduce it a bit, but it is always there. Its definately not a refresh rate problem, becoz the problem is artefacting at the edges. There is some kind of motion interpolation artefact that is going on. There are no problems with 24p stuff though.
The set has slightly more image retention that I was prepared for, however, it was only evident in a totally dark room or using test signals. Becoz of the problem with noisy dark areas, this is a problem that is more evident this year since the black levels are much superior compared to the last few years sets. I also saw some black level fluctuations but it was only a minor.
