120Hz vs. 600Hz – Which Is Better?

Access more than 7.4 million parts at Parts Direct

I get emails every single day and over thet last few days I’ve been getting a lot of questions of if 120Hz in the new LCD HDTVs is better than the 600Hz sub field included with the new plasma HDTVs currently available on the market.

Instead of giving you my uninformed opinion, I went online and found one of the best answers I could on the subject courtesy of Playstation.com

The only thing constructive I learned from it was that 120hz is better if you watch a lot of Blu-ray because 24hz (the BD standard) splits better into 120hz but not 60hz. Also, no device actually outputs 120hz, so you really have to be careful which TV you’d get. Because it would be upconverting your sources to 120hz, and some tvs are bad at doing things on their own.

And this:

As for 600Hz its not a 600Hz refresh Panasonic does a 600 hz subfield drive calculation…

Panasonic subdivides their plasma display panels into 10 sub-fields. Each sub-field is refreshed at a 60 Hz rate. 10 sub-fields refreshed at 60 Hz (10 x 60 = 600) produces a 600 Hz sub-field drive figure.

Is a 600 Hz sub-field drive better for fast motion?

NO. It neither helps nor hurts fast motion on a plasma display panel.

Plasma pixels switch at 1 micro-second; thousands of times faster than the fastest LCD response time. Because of this speed difference, a plasma TV operates different than a LCD TV and, therefore, does not produce the motion blur and jitter produced by a LCD display panel. Plasma TVs do NOT need 120 Hz refresh rates to compensate for these motion artifacts because they do not produce these motion artifacts.

There you have it folks.

    Thanks! I have been wondering what the heck 600hz subfield meant. I couldn’t find anything, not even from Samsung.

    The LCD TVs, LED has a 120 hz motion resolution much greater than the LCDs, leds 60 hz
    60hz is the average of the 300 lines of resolution and 120 Hz dynamic is between 500 and 600 lines.
    99% of LCDs, LEDs said to be full hd full hd are not real and are only 1,080 p resolution in static,
    and plasmas that say they really have full hd 1080p resolution motion.

    Until hd 720p plasmas are often higher than the lcd, led for so long as 1080p lcd, have led 300,500,600 lines of motion resolution plasmas are 720p 720 lines actually

    nothing that is not always the best TVs in the ranking of the world’s most revered site of the world’s pnasonicCNET plasmas and Samsung are always came in the first place.
