The Samsung F4500 is a great entry-level plasma with beautiful blacks and shadows. If you are sitting close to the television, though, its low resolution (720p) will bother you. Also, the panel reflects a lot of ambient light, so this television is more suitable for a basement or for those who watch television at night.
The different results can be explained by using a different picture for measurements and the Automatic Brightness Limiters (ABL) of plasma TVs. A 100% white window like they used means a true white (100%) displayed in a 'window', which is a square at the middle of the screen. Usually, that square covers between 10% and 15% of the total screen. In our tests however, we measure the brightness on a 100% white check board pattern, so the white portion covers about 50% of the screen. On a LED TV, we would get the same measurement as they did. However, things are different on a plasma TV. Plasma TVs change the brightness of their white depending on the total brightness of the picture (the ABL feature). The more white it needs to display, the darker it will be. Therefore, because our test picture has more white in it, it is darker than their number.
The reason we measure both the white and black luminance on a checkboard pattern is to not give an advantage to plasma TVs. If we used a 100% white window like them, the maximum white luminance of plasma TVs would have been the same as some LEDs. This is misleading, because in real scenarios plasmas clearly cannot get as bright as LEDs. If you are watching hockey (where the majority of the screen is white), this is a major issue.
