Panasonic TH-46PZ85U

  Overview Review Specifications Calibration  


Model: Panasonic TH-46PZ85U 46" 1920 x 1080 Plasma Television
Reviewer: Jack Burden

Precalibration Drawback: Picture measures much too blue. Black bleeds into other dark material before properly testing with plugge patterns. After thorough testing we recommend switching HD resolutions back and forth depending upon your HD source component. For example, with our Sony Blu Ray BDP-S1 we found the 1080i output to give us the best picture.

The Panasonic plasma takes little time to calibrate due to limited picture menu options. The menu options are just barely sufficient for this price level product, for instance there are no white balance or advanced color adjustment options. Backing up to the picture menu set picture setting values as follows:

Picture Mode: Custom
Color Temp: Warm
Contrast: 78
Brightness: 67
Sharpness: 14
Color: 46
Tint: -7
Other Settings:
Color Mgmt On
Video NR Off
Black Level Light
HD Size 1
x.v. Color Off

The Panasonic final calibration results at the above settings were 50 to 100 points above D6500K – a good result. We could not dial in the TH-46PZ85U in perfectly without accessing the service menu. Note: these calibrations are specifically for the HDMI inputs. Increase color (to 60) and contrast (to 84) settings if using component or composite cable inputs.

Contrast Ratio Measurement: The Panasonic TH46PZ85U claims an amazing 1,000,000:1 (30,000:1 native). But tested with an ANSI checkerboard pattern pre-calibration contrast measured 568:1 with post calibration testing yielding 705:1. This is an excellent contrast ratio and one of the highest we’ve tested (a good LCD contrast ratio is 250:1 by comparison).
