How much is it really worth to have the option for 48/50hz?

I'm seriously pondering wether a 50hz option is worth the extra dough I would need to shell out for one of the nice EIZO screens.

But they're really expensive as compared to their cheaper NEC, LG and HP counterparts....

So is it worth it?, and does anybody know if 100 hz or 120hz screens are coming soon? and if those screens will be able to adjust their refresh rates such that you can view movies at the native refresh rate thei're encoded onto?

Also, what's the deal with the 29,997fps of dvds'? Is that code for "30" ? and how does it work with a 60hz lcd?

50Hz only makes sense for PAL/SECAM standard video, it's of no real use in the US (http://en.wikipedia.org/wiki/File:PAL-NTSC-SECAM.svg)

48Hz on the other hand is a nice feature since it's double the 24fps used for film.
 
Let me wikipedia that for you...

"When NTSC color was introduced, the older rate of 60 fields per second was reduced by a factor of 1000/1001 to avoid interference between the chroma subcarrier and the broadcast sound carrier."

To be honest, I don't really understand it, but that's why it's 29.997 rather than 30.

There are now one (and soon, another) true 120Hz monitor on the market. In the TV market, there have been some 120Hz and even some 240Hz and 480Hz monitors, but those aren't quite real - the source is still 60Hz or less and they just duplicate the frames in between. But this is desirable because film is recorded at 24FPS and TV is recorded at 30FPS - and 120 is the first number that is dividable evenly by both 24 and 30. When viewing TV (30FPS) on a 60Hz display, everything's fine because it just displays every frame twice. But when film (24Hz) is displayed on a 60Hz display, every third frame has to get dropped and it doesn't look quite perfect. On a 120Hz display, film gets each frame shown 5 times and tv gets each frame shown 4 times, and everything looks perfect.
 
I tested this the other day as my TV supports 24, 50 and 60Hz.
Previously I have had no reason to try 24Hz as everything has been very smooth but one particular film looked a bit jerky so I gave it a go (cant remember which film soz, I've watched too many recently).
It instantly became super smooth.

So yes, handy!

Yes, that's the dropped frame effect I spoke of in the post above. That particular film would look great at 120Hz as well, since 24 divides evenly into 120 but not into 60 or 50.
 
Ok so what I take away from the 29,997 thing is that it doesn't matter much at all XD

And I get that most sources either do 24 or 60 fps... but occasionally, you'll run into something that would like 25/50. And I'm thinking, won't that pose problems even for a 120hz monitor? Or are those monitors able to sync to 100hz too ?

Also, VSync'ed gaming seems like a much better option on a 120hz monitor than on anything else XD
 
A 120Hz Tv is technically the all round better option.
If you really need 50/100Hz, just use that refresh rate.
