Need for a Comb Filter?
Thanks!
Answers: Comb filters are merely necessary next to ANALOG COLOR signals...
And just because it doesn't STATE it...it does not parsimonious there isn't one...
All analog processing of color USES a comb filter and just if you are using the OLD Composite INPUTS....
You don't need it beside the COMPONENT or HDMI inputs...
The OLD signal mixed black and white WITH a color signal and the comb filter UNMIXED the color from the black and white signal.....the digital comb filter was the later and best comb filter design from 10 years ago... that's why they tout it.
Dot crawl is the popular name for a optical defect of color analog video standards when signals are transmitted as composite video. It consists of animated checkerboard pattern which appear along vertical color transitions. It results from intermodulation or crosstalk between chrominance and luminance components of the signal, which are imperfectly multiplexed within the frequency domain.
Dot crawl is most visible when the chrominance is transmitted near a high bandwidth, so that its spectrum reach well into the nouns of frequencies used by the luminance signal in the composite video signal. This cause high-frequency chrominance detail at color transitions to be interpreted as luminance detail.
Another, similar problem is the appearance of a colored noise contained by image areas near high level of detail. This results from high-frequency luminance detail crossing into the frequencies used by the chrominance channel and producing false coloration. Dot crawl can also breed narrowly-spaced text difficult to read.
Dot crawl have long been identified as a problem by professionals since the creation of composite video, but was first widely notice by the general public near the advent of Laserdiscs.
Dot crawl can be greatly reduced by using a good comb filter surrounded by the receiver to separate the encoded chrominance signal from the luminance signal. However, the solely complete solution to dot crawl is to not use composite video, and to use S-Video or component video processing instead.

So basically, any high-ranking contrast video, like contained by your video games, will suffer some quality in need a comb filter. However, the comb filter has be around for a while, so it might just not be advertise in one of the TV's.
I believe that you are misinformed that the Panasonic small screen TH-50PX75U does not have a anti-burn surrounded by, it does, it is automatically build in. Especially since Panasonic is the world's choice surrounded by HD Plasma's! You will be better off next to the Samsung. The comb filter is going to help you next to analog pictures, and the use of the digital is to help upconverting and other scientific stuff.
Just remember alot of these people support Samsung because the representative constantly comes within and gives them incentives.

First of adjectives, all TVs own a comp filter. It is needed in analog cable/TV nouns. Samsung probably considers it a given, that's why it is not in the spec sheet.
You don't have need of it for video over HDMI or component, since the 3 colors are already split.
So, no issue for you.
Second, don't trust too much the anti-burn technology. It is intended for casual protection no serious gaming. Most probably it will a moment ago spread the blur...
Be very reliable with static metaphors though the first 500-1000 hours and you should be OK.
Basically a comb filter takes that rainbow-like effect away when looking at a bunch of lines close together within a picture such as a persons pin striped tie or suit (criss cross patterns) when watching tv. I doubt this will effect your video gaming much. Do not procure a plasma tv because they do get burn-in. Stick next to lcd or dlp formats to avoid burn-in. I have be fixing tv's for 16 years and have see it all.
