Comments on: Is 240Hz worth waiting for?

LCD TVs with 240Hz refresh rate were announced at CES, but are they that much better than 120Hz displays?

i do care for rate and the to 10 bit rate also, the more features you have it will be better, i am an electronic freak so i always like the best stuffs. I love the new sony z series bravia 46 inc 240 hz and 10 bit rate i love that TV i recommended it

The main reason why LCD TV manufacturers came up with the 120Hz TV sets compared with the 60Hz is to reduce the blur on movies, which have a 24 frame rate. 60 does not divide to 24, so some frames are repeated more times than others to make up the difference.
120 divided by 24 is 5, so each frame is repeated 5 times, which creates a clearer picture especially for fast moving scenes.
The 240Hz TV sets will make this even clearer, but at today's price difference I don't think it's worth it.
I haven't bought an LCD TV yet, but I think I will choose a 120Hz TV.
The plasma TV's shiny screen makes me uneasy to choose the plasma TV, even it is net superior to the LCD: no problem of screen refresh rate, 100% colour gamut, true black colour.

Refresh rate is bull ****. At a comfortable viewing distance on a quality LCD display, one can't tell the difference between 60Hz, 120Hz or 240Hz aside from the power of suggestion.

Hey everyone,

I just got done reading all these posts and very cool stuff...I'll tell ya though, all this talk about motion blur and whether it matters or not based on how fast the human eye can process it, etc...I gotta say, to quote deecee above, "one can't tell the difference b/t 60, 120, or 240" is just inaccurate...here's a real world example: I was watching the Stanley Cup this year at a bar, Vizio tv and had to be a 60hz b/c the entire screen was blurry...now, this is an extreme and from a TV standpoint, probably the fastest thing to watch, but I watch alot of hockey & football...so, if I noticed there, but have seen it less blurry on 120 sets (haven't seen a 240 yet), am I just Superman or is there a difference.

I've had my heart set on an LCD...their lighter, more energy efficient, 'brighter", and in some cases, more economical. But if the TV is blurry, all those attributes don't mean squat, right?

So, I ask the sports fans out there...do you have any feedback around which selection I should go w/ based on your experiences??

If anyone has spent significant time watching a plasma, and not just a side by side for a few minutes like the author, then you will notice a decernable difference in an LCD refresh rates. I could not even watch Spider Man 3 at my friends house (60Hz Vizio) because there is a trailing effect on fast action scenes. The movements are not as crisp and the pictures look more washed out. I have not been able to compare the 120Hz models, but I will soon when I buy my next TV.

I have not read all the comments above but I believe seeing is believing. I was just in a Best Buy store and they had a display demonstrating the difference between three Sony 52" displays. They were aligned vertically with a 60 Hz screen on top, a 120 Hz screen in the middle and a 240 Hz screen on the bottom all displaying the same video. The video showed vertical panning, horizontal panning and a still camera with vertical motion on each screen simultaneously. The 120 Hz screen was significantly better than the 60 Hz screen and the 240 screen was a fair amount better than the 120 Hz screen when panning took place. Movement within the frame when the camera was still was not significantly better between each of the screens in my opinion.

Perhaps there was some sort of trickery going on but I don't see how that is possible. I ended up buying a 240 Hz TV because the denmonstration was quite convincing. The cost was about 40% higher than the 120 Hz TV but it also had more features that I found desirable. If you are on a budget I would recommend getting at least a 120 HZ TV if you can afford it. I have read a lot of comments that say that the increased Hz is just marketing hype. Do your research becaue that is simply not true.

I have a Panasonic TC-P54V10 plasma with 600 hz subfield. I don't notice any judder with my machine.
I've heard the difference between 120 and 240 hz can not be seen by the human eye?? What I find
really interesting is that LED backlit LCD's are making a move into the market place. What would
you get if you put an led behind every pixel on a HDTV? The answer is that you would have created a
plasma TV. Soon 240hz will cost the same as 120hz as time goes on and prices drop.

Is it feasible to take, say a 240 Hz system polarize one 120 Hz signal vertically, one horizontally and create 3D TV without signals to expensive glasses with simple polarization lenses??
