Is there really a big difference? I mean, is it going to be noticeable when I'm watching sports or playing vid games on my ps3?
I can't see any flickering at 60Hz on mine and I can generally tell a flickering screen a mile off. It doesn't seem as bad on TFT's as CRT's to me. 50-60Hz CRT's give a headache after a while, but not TFT's.
Best thing to do is to go to your local store and check it out for yourself :)

research the 120hz tech, it is not so great like the people at best buy will make you believe. it actually reduced image quality.
and there is zero flickering on 60hz screen

Thanks for the heads up guys! :thumbsup:
120hz is oldschool, there's 240 and 480hz now... get with the times :)

Doc I have two hdtvs one with 60 and the other with 120hz. I can notice motion blur in the 60hz when watching football, especially when there are close shots of fsat moving action.
If sports is your thing then you may want to consider the 120hz model, but the picture quality for movies is better @60hz.

240 and 480Hz in plasma only... 120Hz is the top in LCD. And personally I think Plasma's SUCK!!! The glass in a plasma will NEVER look right in a well lit room or with window blinds open... they take way too much planning to get them to show well.

Wait...I think people are confused. The jump from 60 Hz to 120 Hz was not to get rid of flickering (as it was known on crt's). It was to get rid of the 'judder' or 'jerkiness' when playing 24fps material (blu-ray etc). I'm not really bothered by the jerkiness (I barely notice it, and when I do it's usually just on slow panning scenes...).

correct. 120Hz or 24p allows 24 FPS material to have each frame refreshed 5 times, instead of the 3:2 method employed by 60Hz displays.
tbh, most people cannot tell the difference lol.

you know, i have been thinking about this a long time, and tbh, if you dont notice anything with a 60Hz TV, i doubt you will notice anything with 120Hz.
plus, i dont think the price difference justifies the purported visual improvement.

Once you've seen judder you'll see it forever.

Ok but only if its true HD UlTrA Vizzion.

I'm using the Samsung 2233RZ 120Hz specifically for 3D Vision. I don't really see a difference when I'm watching video on it, although there is less tearing when I play games without 3D Vision and have VSync off.

The purpose of having a 120hz LCD screen is so that when an inverse telecine is done, the framerate can scale evenly between the player and the screen regardless of whether the film is 24fps or 30fps. It has nothing to do with "flickering" in the classical sense with CRT's. Specifically, 24x5=120, and 30x4=120. However the timing isn't as clean with rendering 24fps on a 60hz screen, and occasionally you may notice a slight jerkiness as a result of some frames being displayed for longer periods than other frames while e.g. the camera is panning over a distance.

the only thing i can tell that 120mhz refresh makes things more blurry. reduces image quality

I don't know if anyone mentioned this yet, but I read that HDMI can only carry video up to 60Hz. So even with a 120Hz screen you can't hook it up to a PC to get more than 60fps with vsync.
It isn't like setting your refresh rate to 120Hz on a CRT and having a 120fps frame rate cap with vsync+triple buffering. You'd still be stuck at 60fps but the TV could sort of blend it out to 120Hz (which probably creates lag and ghosting).

The purpose of 120Hz that matters is judder free playback of both 24 and 30 fps sources. Nothing more nothing less.

Yeah, I know. That's why I was explaining what it isn't for.

I'm not sure of the conclusion in this thread yet. I'm looking around at 120Hz and 60Hz TV's. I'm not sure what I want to buy. CaptN says that the HDMI can only deliver up to 60Hz. How about now, since this thread was made in March 2009?
My main purpose of the TV will be Blu-Ray movies and Playstation 3/XBox 360. Will I be happy with 120Hz, or better of with 60Hz?

I just bought a 120Hz TV last night, just for future's sake.
Honestly, go to a Best Buy or where ever and ask someone to show you the difference with a Blu-Ray movie. The biggest difference I've noticed is that with 120Hz, the movies just don't look "theatrical" anymore. It's too fast/smooth for me and doesn't look theatrical/movie-like to me.
So now when I watch movies, I go 60Hz. Otherwise, I'll do 120Hz for football games, etc.
EDIT: I hope that I'm on the right track. If 120Hz doesn't cause what I mentioned, then oops. That's just what I've been told.

I do see the difference between 120Hz and 60Hz. 120Hz makes the movie go smooth, super duper smooth, right? But on regular channel, analog channels I mean, it's just gonna flicker as if it will stutter, right? This is why I am not too sure about it...

After watching my new 120Hz for a day now, I haven't seen any flickering or stuttering. I don't know what everyone else is talking about.

So you got the Sony Bravia 40". How is the picture quality.. stunning, I imagine? I went to Blockbuster store this past weekend, the Sony TV was hooked up to PS3. I'm not sure of the exact model number of that TV. But the movie in PS3 was Ice Age 2, the picture quality was far beyond amazing. Which is why I'm starting to look more into this...
I'm not sure if this is the right choice for me: Sony Bravia 32" 1080p 120Hz LCD HDTV (http://www.bestbuy.com/site/Sony+-+BRAVIA+XBR+/+32%22+Class+/+1080p+/+120Hz+/+LCD+HDTV/9222502.p?id=1218062424675&skuId=9222502)

120 Hz is meant for movies that are encoded at 24fps. When the TV then detects a 24 Hz signal it then displays the same frame 5 times(works for other framerates as well). It's also known as frame or motion interpolation.
