What's the deal with 75hz monitors?

[koksy]

Do they actually run at 75Hz? How come there are so few of them? How come it was such a huge breakthrough to make 120Hz monitors if it was no problem going from 60 to 75? So many questions D:

[Helloworld_98]

for your first question, yes, second, because it was to please CRT users in the early days of the CRT to LCD switchover, well doubling the hz on a monitor with double the pixels on them is pretty hard to do considering voltage, heat, etc can cause failure a lot quicker.

think of a 120hz LCD like taking an i7 920 and overclocking it 100%, it's not going to last as long whereas if you used a w3580 and overclocked it to the same speed, it'll last quite a bit longer.

They actuall do have a gaming LCD monitor that is 120 hertz now and a lot of the new TVs are coming out like that as well.. LED is going to be the next new big hit soon

also 120Hz monitors can do 3D, 60Hz per eye.

No they can't

edit: thought you said "all"

depends on video card as well.
Nvidia supports this with shutter glasses,
so it alternates showing 1 eye to the other.

i didn't know there were 120Hz lcd that didn't suport this.
can you give an example?

MadHacker - any 120hz LCD that uses interpolation cannot do 3D at 60hz.

However, any LCD on the market can do 3D at 30hz.

thanks good to know.

since standard film is only 24hz it makes u wounder why there is the push for 120hz 3d and if its nothing more than forced obsoleteance

[koksy]

Very interesting.

So how come there are so few 75Hz? the more the merrier, right?

Also, does v-sync work the same way on 75Hz monitors, as with 60Hz? Or will you still be limited to 60fps on a 75Hz monitor?

you have to consider the difference between TVs and pc monitors, though. both handle the refresh rate slightly different.

Because 75hz was a dead standard.. nobody cared.

VSYNC locks you at the refresh rate that the display is set to display.. 24, 25, 30, 60, 75, 120. anywhere you choose.


Serpentarius - That link is junk for the most part. Refreshing a pixel with information it already holds gives no performance increase. No LCD actually works beyond 120hz (everything beyond that is interpolation), and only approximately 6 displays on the market today are actually capable of producing a TRUE 120hz image.

most of them are very scarce.

120 divides into 24 nicely, by 5. 60 doesn't :cool:

u need special cameras why why not just use 30fps film (or capture now) as u do for tv, or in europe with pal they use 25frame cinema and 50 frame tv so why do they need to upgrade it seams perfectly linear

[MadHacker]

actualy NTSC framerate for tv is 29.976 FPS
what does that divide into nicely?

59.952Hz :D

I was simply implying 120Hz allows 24fps material to play without judder, something LCDs normally cannot do.

[STEvil]

Also they are going for 120hz because thats what you need to do two 60hz images to produce a playable 3D picture for gaming.

120hz means backwards compatability with everything that is less than 120hz.

What are the true 120hz pc monitors?

[STEvil]

What are the true 120hz pc monitors?

Acer has a couple, Alienware uses them in their knock-off body jobs.

thats assuming you mean 1920x1080 panels. There's one or two that are 1680x1050, but who cares about that resolution? ;)

edit - everything else is a "TV"

[Shalamay]

so, no 1920x1200 panels?

Are all the ones from Acer true 120hz? (that are marketed as 120hz)

[STEvil]

There's only two that I know of.

[Cow2kie]

What are the two that you know of? ;)
