I just calibrated a 65-inch VT25 with a build date of May ’10 and it performed beautifully in the THX mode. Gray scale tracked pretty flat (the best I’ve seen from a Panny) and color accuracy was very good. By far, the best I’ve seen from any Panasonic PDP.
Gamma is still a bit on the low side. I measured an average value of 2.13, but at least it was linear from low to high.
A pretty nice panel.
