Sony unveils 240Hz LCD TV

gadgetzone.com.au writes: "Sony has been at or close to the forefront of TV technology ever since the good old Trinitron. Today the company went even further by introducing the first ever 240Hz LCD TV and the world's thinnest TV. Hold your breath until December, because that's when Sony's 240Hz LCD TVs will be available to the public. Currently LCD TVs are topping out at 120Hz for consumers, and that's already a significant improvement in speed over the standard 50-60Hz of normal (for want of a better term) LCD TVs."

im on the same page as YOU XD.

Bombibomb3529d ago

Getting one of these for Christmas! :D

jtucker783529d ago

Yes, but did you notice the contrast ratio is only 3000:1?
That's almost as low as the average PC monitor!

Current Bravia Engine 2 Sony's are 33,000:1 and Samsung series 6 are up to 50,000:1

I guess it depends on what is most important to you. 240Hz would be amazing for a fast paced FPS team deathmatch session.
But for picture quality 3000:1 is a little low for me. I'll wait until the 240Hz catches up with the current models on the market.

SafeRat3529d ago

3000:1 is the norm - The '33000:1' and '50000:1' ratios are merely Dynamic Contrast Ratios. I.e, you only ever need to pay attention to the real CR, as the dynamics are there purely to coax consumers into tihnking ':O this one has a higher contrast ratio! It must be better!'

In reality, pretty much all the manufactures measure their own Dynamic CR's differently, but the only real way to compare them would be using the 'real' CR's - the 3000:1 stated here.

jtucker783529d ago

Hey you know your stuff SafeRat.
I guess Dynamic Contrast Ratio is cheating a bit by darkening dark pictures and lightening bright pictures to create the 33000:1 and 50000:1 figures, but 3000:1 isn't amazing.

I guess I'll have to save up for one of Pioneer's new Kuro plasmas instead :S

......picks up jaw.

and i was just getting used to the fine tuned xbr5.

Bluray is gonna look retarded with 1080p/24p/240mhz on. Ill probably wait for next batch of these beauties.

legendkilla3528d ago

for sure get a Pioneer plasma there the best on the market now...
i have a Pioneer PDP5060HD . Its only 1080i but it looks just as good as the new Sony XBR and Z4100 tv's from Sony :)

ravenguard883528d ago

It's not 240Hz/Second, because Hz is defined by cycles/second. "240Hz" means "240 refreshes in a second."

Violater3528d ago

The only reason this makes me happy is bc it will drive the prices of the other tv's DOWN!

Leathersoup3528d ago (Edited 3528d ago )

Where did they say Hz/Sec? Did I miss something?

That would be like cycles/second/second...

Ahhh pwnsauce beat me to it.

AAACE53528d ago (Edited 3528d ago )

I thought the 120 Hz was a dramatic improvement. But if you have a 240Hz TV and a Ps3... Wow... I believe people won't leave their homes for a while!

I can't wait to see how much better this is. Should really boost LCD TV sales!

Sony really does like to provide consumers with cutting edge technology.

@PostedUp. Hz reflects sony's true vision when they were creating the Ps3. They said the ps3 would be able to display at 120 frames per second, but no TV's were currently able to produce such a picture... So, they made it themselves! Now they are moving up to 240, which should blow peoples minds, and look as realistic as it can get at this point!

If you want to see what 120Hz really looks like, go to best buy and they have TV's set up showing the difference!

Ben10543525d ago

sony has found a great piece of technology for its ps4 that will be able to run any game at 240fps, so they are starting to roll out 240hz lcds so people can fully enjoy the ps4 soon as it comes out

It's a bit nuts eh! Can't wait to try it out. I thought 120Hz was brilliant.

PoSTedUP3529d ago

what do these "Hz" mean? like what major effect does it have on the picture/TV etc.?? sorry dont know too much about this stuff.

pwnsause3529d ago

Hz for a Tv is another way of saying Frames per second.

SafeRat3529d ago

240Hz is NOT 240fps. Hz is the screen refresh rate - not the same thing as frames per second. If you played a 60fps game on this screen, then each frame of the game would be displayed four times per second. The 'motionflow' part of the 240Hz is a fancy name for frame interpolation - in basic terms, the TV 'guesses' what's in between two of the frames of the 60fps game (8 refreshes on the screen), and then would display what the TV THINKS should be there.

Generally Sony sets are good at frame interpolation, though it will never be perfect, as it's effectively making up frames that aren't there. That's how you start getting artifacts on 120Hz, so, unless they've somehow erradicated the problem (very unlikely), you'll still see artifacts.

Just thought I'd let you know :)

edhe3529d ago

Hopefully this'll drive a nail through 120hz model prices.

JoelR3528d ago (Edited 3528d ago )

having a higher frequency of updates doesn't make up frames (interpolate) but instead it allows repetition of frames instead

THE NEED FOR 120 hz WAS A RESULT OF THIS DISCONTINUITY:
a 30fps (29.97 actually) signal is standard TV
a 24fps signal is standard movie

a 60 Hz tv updates the screen 60 times a sec and allows every
tv frame to be duplicated 2x

BUT 24 does not go evenly into that frequency so a conversion called a 2:3 pulldown occurs. It spreads out 24 frames into 30 by placing one frame on the screen three times and the next one after that two times, and repeating this pattern ad infinitum.

poly frequency tvs were created just before 120 hz. They did 60 hz and 72 hz which allowed movies to show a 3 frame repeat cycle rather then the 3:2 pulldown) but that required additional circuitry so the 120 hz was launched...

120 IS THE FIRST COMMON MULTIPLE OF 30 and 24.

Therefore 120 hz allows allow tv signals to repeat the frame
120/30 = 4 frame repeat
120/24 = 5 frame repeat
the fact that the number of frame repeats no longer is required to change from frame to frame on movies reduces jitter in the image on horizontal pans

Europe had a different set of problems as 50 hz didn't support 30 fps so they ran 25 fps which essentially meant that they didn't do a pulldown on movies but movies shown on tv gained 1 frame every second (so movies were usually 1-2 minutes shorter when shown on tv)

pwnsause3528d ago

thats for telling me that bubble up.

IdleLeeSiuLung3528d ago

That is how I understood it as well, so I'm not sure why one would need 240Hz. The motion isn't going to look any smoother, as it is limited by the actual frame rate of the movie/tv show/game.

I suspect this is a marketing gimmick. I mean why not, anything with a higher number is better right?

JoelR3527d ago (Edited 3527d ago )

NOT - It just doesn't make sense as anything other then marketing... 240hz doesn't fix the last remaining issue...

600hz would allow Pal/Secam/NTSC/HDTV/Movies all to work properly as that is the LCM of 24,25, and 30

so no real purpose between 120 and 600

sak5003529d ago

Now we can finally play games at 120fps.

Fishy Fingers3529d ago

You can already do that on any 120hz screen.

n4gzz3529d ago

I don't think you can play games on 120 hz. I read everywhere that you actually have to set to 60 hz to play game properly.

qwertyuiopasdfghjkl3529d ago

For those with console gaming, 120hz upscaling comes with a catch... because your TV has to upscale 60hz outputted from console games, your getting some significant input lag. Not to mention games running at 30 frames are upscaled twice, once by the console to 60hz, and another by your TV to obtain 120hz.

This new TV from Sony is really only useful if you can run PC games at or above 240 frames per second. Not to mention you won't be able to do this unless graphic card companies release a patch or something to support 240hz.

Immortal Kaim3529d ago

Wait a sec, this is an Australian site, it is saying these TV will be available in December but Im fairly certain they are talking about the US?
