3D Glasses Explained: Why 120Hz Isn't Enough - HD ...

[R0ssee]

left guy looks nerdish

[gamertag223]

YES CAUSE WE CAN SEE A FUCKING DIFFERENCE BETWEEN 120Hz AND 240Hz

[Crowcaine77]

@Crowcaine77 240Hz seems to be the easier standard to create (doubling the 120Hz frequency) than creating a completely new standard such as 160Hz, but it's true that over 120Hz is necessary for completely smooth/flicker free, whatever you want to call it, playback.

Thumbs up if you qo to the movie theater && keep the 3D qlasses && youu take out the lenses && use them to look dorky && cool xDD, haha ii know ii do that ;DD

[kuzweliveordie7]

i can never view 3d images...

[gokhanbug]

i dont agree , Plasma tv look like 1950 s tv for me, i rather led or lcd tv..

[tlv156]

I like LCD's better for my budget. If you have the money to go for the Plasma, go for it, but the LCD HD TV is by far the best bang for the buck there is. Not only do you pay less, but the TV's on average last twice as long as CRT designs. Once the gasses in each cell die out (and they will although they have gotten better from my understanding) those cells die and you lose quality over time. That's what I was taught when I sold TV's about 8 years ago anyway. Plus no screen burn on LCD's

[raykupal]

my question was still left unanswered for 4 months now

60hz isn't enough, you can see a lot the difference with 120hz and 240hz. In games on lcd screens with 60hz you see the tearing, with 120hz you don't. I think this all benefit are fake, I started to have problem with my eyes when I change to LCD 60hz like a 60hz crt screen. I think the companies said that to produce screens cheaper.

@jonidimo

LCD displays do not refresh in the same manner as plasmas or CRTs; the pixels simply change state individually as the content being displayed changes. The only visible difference between a 60Hz LCD and a 120Hz LCD will be in how well it handles motion. Your eye problem was not caused by a difference in refresh rate.

[RenegadeFury]

@troy2062 not true, with the glasses it pretty much is like looking at a crt at 60hz

[troy2062]

@RenegadeFury

That is an effect induced by the shuttering of the glasses themselves. It has nothing to do with the display nor his statement.

[Crowcaine77]

@troy2062 incorrect. The glasses shutter at the speed of the monitor. If the monitor isn't refreshing fast enough to be "flicker free" then it's the monitor that is your problem.

[troy2062]

@Crowcaine77

No, my response had nothing to do with shutter glasses, nor did his original statement.

@syleishere Not ture... I work at Best Buy and by no means do I consider myself an expert on the matter, but I do know the fundamentals, how they work etc. and can assure you I can see a difference when looking at TVs side by side, it's not as noticeable as plasma compared to LCD, but it is there.

[Crowcaine77]

@syleishere He is marketing for 240Hz manufacturing, because it's needed. He's talking about 3D here. You're right, the human eye, in terms of how monitors work, cannot tell the difference between 120 and 240, however, they CAN tell the difference between 60 and 120, which is what these screens will be displaying in 3D respectively. That is why 240Hz must become the standard. I am in complete agreement with him, after using a 120Hz monitor for 3D for a year. I want and need 240Hz.

[raykupal]

how come some pc monitors running 120hz can handle 3d but not tv?

[raykupal]

cool! but how about the 120hz LEDs? are they fast enough?

[momorgoth]

@raykupal LED backlighting does not improve refresh rate.

[gowpopt2tmiley]

thnx man awesome finally u guys made it clear 4 me

[gowpopt2tmiley]

thnx man awesome finally u guys made it clear 4 me

[NEFTALI1984]

how bad the 3D tv could be for your eyes.

[psycopig]

They say 120hz in 3d isnt flicker free. My nVidia 3D Vision on my 120hz 23inch LCD definitly does not flicker.

[Ashiman]

so DLP and plasma are 3d ready at 120hz , whereas LCD isnt so cool

[DoCWaSaBe]

nice vid guys but the voice levels are way too low when u two where talking
