Color

The GT50 boasts accurate, rich colors.

To test a television's color integrity, we run three separate tests. One tests how closely the TV's color matches the ideal standard color gamut; the second tests how well the television maintains its color's temperature, which is separate from hue or saturation. The third test reveals how well the television transitions from brighter or darker shades of the same color.

The P50GT50 tested with a very accurate color gamut. Its red, green, blue, and white points were all almost perfectly matched to the Rec. 709/sRGB color gamut, which we map against the CIELU'V' color space. This means that the GT50's content will be accurately saturated, and look exactly as the director or animator intended it to look.

The GT50 tested with a few minor color temperature errors, but nothing too extreme. Color temperature refers to the flavor or shade of the light passing through the television, which ideally will stay the same temperature from minimum to maximum intensity. The GT50 has a few areas of perceptible deviation, but these are mild, and won't be overly noticeable during playback.

The GT50's color curves were shaky, though they describe the proper curve. This means that there'll be a wide spectrum of varying shades and hues on screen, which aids in realistic shadows and edge gradation. However, the curves were quite bumpy, which means some banding will occur during particular color spectrums.

Black Level

A deep black level is the hallmark of a quality plasma.

The GT50 tested a black level of 0.04 cd/m2, which means a light output of four hundredths of a single candle per square meter—in other words, not a lot of light. This is very good, as it enables the TV to produce very realistic night scenes, shadows, and edge lines. It also gives the greyscale more room to work within, meaning a wider spectrum of intensity levels and a smoother transition from one to the next. Its resulting contrast ratio is above average, though it's not as impressive as the one we measured from the P50U50.

Viewing Angle

The GT50's screen offers ample viewing flexibility.

A TV's viewing angle refers to its horizontal viewing angle, or how far from center the screen can be viewed without becoming distorted. The GT50 tested with a massive viewing angle—and in this case, bigger is always better. Its total of 179° means that almost the entire screen is viewable to the most obtuse possible angle. This is a great result for large-group watching, or wall mounting within a large space.
