Panasonic TC-P55ST60 picture settings

Calibration report using these settings:

TV software/firmware version tested: 2.684

Below you'll find the settings I found best for viewing the Panasonic TC-P55ST60 in a dim room via the HDMI input. Your settings may vary depending on source, room conditions, and personal preference. Check out the Picture settings and calibration FAQ for more information.

Calibration notes: Prior to calibration the ST60's Cinema setting came closest to the ideal, though its grayscale was relatively greenish-blue and is color likewise mediocre, with de-saturated and otherwise errant primary colors. Thanks to Panasonic's extensive controls I was able to mostly fix those issues resulting in error levels below the normal threshold of perception. It wasn't all smooth sailing though.

The color management system worked well to home in on the HD standard color points, resulting in excellent measurements for everything but Blue, which still showed a modest error.

On the other hand, the ST60's multipoint grayscale and gamma control didn't work as well as most such systems I've tested. At 40 IRE and below, where gamma was most problematic, the controls did little to improve matters even when I resorted to extreme settings. I ended up rounding off to the most-effective large number in most cases. The ten-point grayscale was quite coarse at most levels; in one memorable instance, going just one pip in Blue gain at 40 IRE caused it to swing wildly between slightly plus and extremely minus blue. The 40 level also showed significant variation depending on whether I measured a run (when generating a report for example) or focused on that single IRE point (during adjustments for calibration). There was also a good deal of variation from one measurement to the next at 90 and 100.

The menu system is also annoying for calibrators. It times out too quickly, jumping up to obscure the measurement area, and navigating from selection to selection requires jumping up a menu level instead of begin able to do it directly.

My TC-P55ST60 sample was aged 150 hours before calibration and review, but there's no reason you need to similarly break it in before you apply the settings below.
