Why do the 4K tvs have 120 instead of 240Hz? Isn't 240Hz better?
1522046
240 hz refreshes much faster than 120 so better for action or sports. No one is broadcasting in 4K maybe in the future but for now save your money.

Basically right now 4k is the newest technology & there's not enough content out in 4k yet. It's a much higher resolution so u probably won't be able to tell the difference anyway. But I'm sure within the next 2 years you'll see 4k at higher hz. My opinion not worth the money right now. Stick with led tv at 240Hz with a quad core processor. Cheaper & will hold up well for a few years

No plasma TV's have "120Hz Technology". It is not needed for Plasma, as they don't have the motion jerkiness problem the LCDs have. 120Hz is an LCD only technology. 120Hz is for LCD tv's because of the latent shutter speed to turn an LCD pixel on or off. This is actually the inverse of the frequency, or .0083 seconds; which is the switch time for the crystal (This is not to be confused with response time or fps; both of which are also different performance metrics). The crystals turn on and off to allow light to pass through or block it for dim/dark scenes; or to turn a color on or off. A pixel in a plasma TV is actually a tiny one-pixel "tube" TV. Tube TVs have never had a problem with action smear or latency. Plasma pixels have a near instantaneous on/off time, so implementation of 120Hz technology not only does not apply, it is not needed. The pixels have no latency; you'll never see a 8ms or 6ms response time attributed to plasma TVs, because the "pixels" go on and off as they are energized or de-energized; with no latency (At least not humanly perceptible).

I had the same concerns as you regrading Hz. There is a CONSIDERABLE difference that you can notice between 60Hz and 120HZ when watching fast paced movies (fast n furious) or sports. However, there is less of a difference when you move from 120Hz to 240Hz. I've read that the 650B series/model is the same as the 850A series, except the 850A is just somewhat slimmer/thinner. I opt'ed for the 750B because I got a great price from SEARS ($1999.00) and I compared it to Sony's XBR9 series and I liked the Sammy better. Also, I was reading the blogs and although the 850A is a great TV, the majority of comments stated the 750 is the way to go. So you are aware, BB was selling the 850A for $1899.00 on their web-site.

hey guys the 32 650 is 15,000:1 and 5ms if you want the 50,000:1 and 4ms and the 120hz one of the same tv you have to buy the bigger size one of the same model

120 basically doubles the refresh rate of the images. That is very good especially if you like sports. .. I had a Sony that I returned because it said it was 1080 pixels but it was really only 720... don't you hate being lied to? I do...

"The only significant difference between the 120hz or 240hz systems will be in presenting 3D content. If you think you are going to be interested in viewing 3D movies and TV shows, then you should get a 240hz system. Why? Because 3D works by showing each of your eyes only half the image on the screen - this is what makes the image three dimensional and why you have to wear special glasses. Because of this halving, your 120hz TV is really only showing 60hz to each eye (and 24fps does not go into 60hz very well). If you have a 240hz TV, each eye gets 120hz and you'll be able to watch both 24 and 30fps shows without any image manipulation."http://www.tekspree.com/what-are-tv-hertz-and-why-are-they-important/ "The only significant difference between the 120hz or 240hz systems will be in presenting 3D content.

Watching sports on this tv sucks for me. But that is just my opinion. I think that the 120HZ would be prolly be better.

Considering they keep uping the Hz we may always be chasing the speed. The HDTV's from just last year were 60Hz. The higher end one's were 120Hz and now we are at 240Hz. I am going for the size. I hope I am making the right choice.

Its the refresh rate. I own this TV and the TV I used to have was 120hz. I was weary about getting the 60hz but the price was unbeatable for this one and I see absolutly no difference from 120hz

Refresh rate at 120hz is how long it takes (in milliseconds) for the scene to pull up, action, and there is a difference. When two TV's (side by side) receive the same signal, the Toshiba responds faster than that of just a 60hz HDTV. I have two sets side by side (one for DVD recording and playback) so this is a television that will receive the signal and process it faster than the other. Proven to be the case.

A real advantage of a 120Hz and higher refresh rate is to properly display 24p movies. What is a good refresh rate? As said above, the Refresh Rate is mostly a marketing gimmick. While the 120Hz alone is not worth it, it usually come with a better panel, which could have a better response time and produce a better image.Panel refresh rate 60 Hz 120Hz 240Hz +Normal TV or Passive 3D Ok Good GoodWith Active Shutter 3D Invalid Ok Good

Really the refresh rate is fine for viewing any program, DVD or Blu-Ray. If you are playing some sort of advanced video game you might wish it was 120 but I've never once thought it was inadequate for watching TV.

TV and movies aren't recorded or displayed in anything higher than 60hz would cover. In my opinion, the 120hz is the way to go. Just google "240hz a gimmick" to see lots of info on the matter.

I was wondering the same thing, It has HDMI 1.4 which would support 1080p with 120hz so that threw me off.

What he means by "true" 120Hz technology is that you aren't getting 120 Hz from your source, the TV just creates it, kind of like upconverting an old DVD, you dont get "True" 1080p because the DVD is only 480p. You also don't get true 120Hz because the DVD is 24Hz or 30Hz. So, technically speaking, right now I don't know of any way you can get a true 120Hz picture other than maybe a very high end PC if there are any that support it. That is also assuming that the TV would accept it as input, many TVs are strange like that.

It is both. The TV has software that convert the 120Hz to 240Hz when the TV is ON. Thanks

I'm also trying to decide between the two. Only difference seems to be that the 52b750 is 240hz instead of 120hz for the 55b650. I think that has something to do with response time. Hoping that we can get responses indicating whether or not the average person can notice the difference when watching tv. I would rather spend an extra $100 for a larger tv but wonder if I would be missing out on a better picture with the 240hz.
