Question: Is a $2000 industrial plasma good enough for critical monitoring?

Adam Wilt reports on a science experiment conducted by Pete Putman via HPA:

"Question: is a $2000 industrial plasma good enough for critical monitoring? (LCD problems: costly, high black levels, off-axis color/tone shifts, bad color gamut on CCFL backlights). Took stock Panasonic TH-42PF11UK and tweaked with calibration tools. Got stable gamma with a couple of “speed bumps”, consistent if not perfect RGB tracking, great blacks."

"Color gamut exceeded 709, even large portion of P3. Green was a bit shifted towards cyan (for brightness). Gamma at 120 nits was 2.5; looked very smooth (movie mode), a bit of a bump in 2.2 gamma. Max gray drift was 145K in the shadows; bit of a blue bump around 70%. Brightness 100-120 nits (29-35 ft-Lamberts), contrast 1189:1 (checkerboard), 11370:1 sequential (gamma 2.2), black level 0.124 nits."

"Wanted better; got a Cine-tal Davio using a 3D LUT to correct residual color and gamma errors (as seen in the demo room). After calibration, color accuracy was comparable to reference-grade CRT. Best of all: a very cost-effective solution."
