60/120/240 Hz?

[npanzeca]

Is there that big of a difference in these 3 hz? I understand that 240 is the best but is it really worth the price difference between a 120 and a 240? For example I saw a Sony 240 that was $500 more than its 120 counterpart. Any help with this is greatly appreciated. Thanks.

In simple terms, hz refers to the refresh rate of the screen. 60 refreshes that many times each second, same with 120, same with 240.

There is a difference when playing video games. You can feel a slight lag when playing online games.

What about TV or movies?

Is 120 sufficient for a 1080 LCD?

120 is enough to watch movies in 60p and give it that fast motion look.

In my opinion, yes. I have a 52" Sony LCD 1080p 120hz (I keep Motionflow ON for cable, OFF for blus). I don't have any experience with 240 hz other than what I've read on here. I would stay away from 60 hz, but that's just me.

The value for you would be dependent upon the type of material you would tend to watch.

60hz LCDs will display 60fps, which is equal to the broadcast refresh rate, however introduces judder to 24 fps material(film).

120hz LCDs can display 60hz material by displaying each frame twice or interpolating motion from one frame to the next, so long as that option is available for the tv in question. As for 24fps material, some 120hz LCDs can play back this material at it's intended rate by playing each frame 5 times. This removes any judder that was a result of the 3:2 pulldown associated with playback at 60hz. You should check the specifications to see how a display handles 24fps material.

240hz LCDs double the 120hz resulting in additional frames for interpolation. It's believed that 3d displays may require refresh rates of at least 240hz, but that is not known at this time and none of these displays are considered 3d displays(though some may be 3d ready).

IMO, 24fps playback is important for any blu-ray viewer, so they can view the film as the filmmakers intended. However, I don't see much benefit from 240hz LCDs over 120hz as of yet. I would recommend a good 120hz may serve you better than a similarly priced 240hz model.

Best of luck.

kpkelley said it right, my bad, I meant 24fps not 60p :P

kpkelley, that explained it very well. Thanks to all for your responses.

Yes, he did in fact explain the differences very well but not what other people might prefer.

When I bought my 120 Hz LCD (Sony Bravia) the showroom had another Sony Bravia running at 240 Hz side by side playing the same movie (Transformers 1). I could definitely see a difference. The 240 Hz TV displayed a greater 3D effect and looked much more digital like rather than film like. The motion was smoother. Motion flow was undoubtedly set to standard or high. I'm not saying that I prefer watching movies the way the director had not intended, but if that's what you like, then 240 Hz is what you want.

I bought a Samsung 46" 60hz and am more than happy. I don't notice motion blur, even when I watch Sports (hockey, NFL). It might be there, but it's either negligible or not a distraction as far as I'm concerned. Same goes with movies.
