Color gamut is measured using a saturation sweep that samples the six main colors (red, green, blue, cyan, magenta, and yellow) at five saturation levels (20, 40, 60, 80, and 100%), providing a realistic view of color accuracy.
We begin by showing you the Standard mode.

Since this is a pre-calibration result, there is room for improvement. The blue grayscale means that cyan, magenta, and red exhibit significant hue errors. Adjusting the color temp preset and/or the RGB controls helps there. Of equal concern are the saturation errors below 100 percent. You can see especially in the blue and red primaries that 20, 40, 60, and 80 percent fall well below their targets. The luminance chart shows that color brightness has been increased to compensate.

These are the results gathered from Movie mode prior to calibration. We already established that the white point is nearly perfect without adjustment. The hue errors from Standard mode are now corrected, and the saturation levels get closer to their targets. Overall color errors are only visible for red and blue.
Since we only changed the Blue Gain control during the grayscale calibration, we had to address the F8500’s CMS to see if we could make any other improvements. As it turned out, all we had to do was change the Color Space option from Auto to Custom. No other changes were necessary.

Blue and red still show a little under-saturation, but they are much better than before. The slightly-elevated luminance helps compensate. at least all of the errors fall below three, which takes the F8500’s color from good to excellent.

An average error of 1.37 Delta E puts the F8500 among our top group of displays, including monitors and HDTVs. The fact that this is achieved with only a few minor adjustments speaks highly of Samsung’s engineering and build quality.

@n3cw4rr10r It's not overpriced at all, but rather an outstanding value (though not as good a value as the sorely-missed Panasonic P50ST60). The image quality is tremendously better than any 4K TV, even with perfect 4K source content, even if they sold the 4K TVs for $1500 or less. The difference in contrast(dynamic range) is the most important, and it is huge. Side-by-side with the plasma, no one would pick any 4K LCD.
I got a Panasonic VT60 at the beginning of the year, just as stock was running dry. I'm still amazed by the picture quality.
Actually OLED is arguably already there or getting there. Some people were able to pick up LG's 55" OLED TV for $2000 (not a typo) via in-store at Microcenter.
For a more universal price-point, it's newest revision is now going for $3500.
Most HDTV's have a "GAMING MODE" option which disables video processing inside the HDTV for a particular HDMI input such as your game console might use.
Having said that, burn-in issues have never been completely solved so I wouldn't game on a Plasma anyway (seems an important thing to mention doesn't it?).
It's a very important factor for plasma and OLED screens, particularly for anyone who wants to use them for gaming. Permanent burn-in is almost nonexistent with modern plasmas, but a bright spot from a network logo or HUD element that takes dozens of hours to clear up is a major deterrant to buying a plasma or OLED screen. And some plasmas handle this much, much better than others do.
I'm still on a 2005 Sony flat screen I got for $15 last year. I don't know how to express this properly, but it's one of those TVs with a... big back? It's not one of those thin TVs.
My only regret is being talked into paying $195 for an extended warranty at Circuit City which was never used...but this was still new tech back, then. My only complaint is that it sucks a lot of power and produces a lot of heat (short winters where I am)...hence the reason for only being used at night and for a limited duration in the bedroom anymore. I know the newer ones run cooler and are more efficient but I would never pay $1800+ for a 50"+ 1080p HDTV ever again unless it's OLED.
With that said, it's great to see sites like Tom's still taking the time to review plasmas!
It's got a nice, good quality image and it says it's assembled in Poland. To be quite honest I did find it provided the best bang for buck and since I wanted plasma anyway ( I think it's better than LCD for TVs ) I'm super happy.
Didn't even know LG made plasma TVs but I wouldn't be surprised if the actual screen is made by Panasonic or something.
Yes, I'd really like OLED but OLED would be great as a smaller PC monitor first and then for a large TV. For a TV I think plasma is fine but even though I got a good IPS LCD I'd just love an OLED 23-24 inch monitor.

I bopught my 50" Plasma last year. I just bought my LG 65" 4k TV this year because while 4k may not be prime right now i got a steal on it. My 4k is equipped with one of hte best IPS displays (after calibration) that I've encountered so far. The picture quality on this set easilty surpassed the other 4k TV's I was looking at in the electronics store probably because the display gets so dang bright.
Side by side with my Sammy 1080p content in my basement is a hit or miss. Blu-rays look great on both so its hard to say which one is "better". The upscaler on the 4k does a hell of a job processing the image because even up close I can't detect pixels. However on the Plasma with 1080p content I can see obvious pixelation while standing right in front of the television. Dark space scenes look better on my plasma thought w/o a doubt but only when the room is dark. Any amount of light seems to bring the IPS 4k display back in range with the Plasma.
Now on to 4k. Native 4k content on this TV is breathtaking; and takes the viewing experience beyond what my Plasma could ever offer. The clarity, sharpness, and amount of detail is simply stunning and I'm not wowed easily.
So will a good 1080p Plasma offer better contrast levels In a dark room than a good 4k LCD? Yes, Yes it will. Does that benefit translate into a better picture than a good 4k display showing native 4k content? Not in my viewing experience. Not even close. It's debateable @ 1080p as it is with my 2 TV's.
Also, as far as I recall, 2.2 gamma and the sRGB gamma are not exactly the same.
Image retention would have been useful to see as part of the testing. I have a 2008 Panasonic Plasma and although it has no problems at all with television and movies it has drastic IR with games. I don't know if it has something to do with me using a DVI to HDMI converter, but it is completely unusable with PC gaming because of IR and that is with the set even set to minimum brightness.
