LG, where did you go wrong? The black level on the PN6500 is so bad that it only manages to get a contrast ratio of 610:1. These days, a contrast ratio of 1000:1 is considered average, and we typically see televisions do much better than this. That's why the PN6500 is such a surprise. Its white level of 122.60 cd/m2 is fairly bright for a plasma display, but having a black level of 0.2 cd/m2 almost defeats the purpose this technology. Why buy a plasma TV if it doesn't have a good black level?
A black level this bright should not be seen on a plasma TV.
We noticed that content on the PN6500 had a muted appearance as a result of its shoddy contrast. This is why a TV's black and white levels are so important to picture quality—they help give a more lifelike image. Isn't that what you want in a display? Unfortunately, the PN6500's picture simply looks "meh."
I have literally no idea where this "review" came up with these numbers and conclusions? This bad of a black level performance isn't mentioned in ANY other LG plasma reviews I've seen and certainly doesn't mesh with my own personal experience with my PN5000, which has very good black levels (definitely not inky black like some of the Panny's I've seen but much MUCH better than my other LED set). Obviously my set was only $600 so I didn't expect it to rival a $1500 plasma in terms of sheer picture quality but it is much better than any of the far more expensive LED sets I've seen...
For example, here is PC Mag's take on the PN5300 (which is again very similar to the other PN series plasma's):
We test HDTVs with a Klein K10-A colorimeter, DisplayMate's test patterns, and SpectraCal's CalMAN 5 software after basic darkroom calibration. The PN5300 doesn't get particularly bright, reaching a maximum of 135.9656 cd/m2. Its black level of 0.0449 cd/m2 is decent for a budget plasma screen, but not especially dark, and these middling levels make a contrast ratio of 3,028:1. It performs well for its price, but it isn't amazing. Color accuracy is similarly decent but not perfect, as seen in the color chart below. The squares represent the ideal color levels based on CIE standards and the dots represent the measured levels. Red was slightly oversaturated and whites veered a little warmer than ideal, but all colors were in acceptable range.
