120hz LCD Monitors?

One quick question is there any 28 to 30" LCD Monitors with 120hz?

thanks
 
Sort of on topic, are there more 120Hz monitors coming out in the next few months regardless of size?
 
There is a 23.6" LG coming out soon supposedly. They have been showing off a 28" at shows for a while, probably will come out in 6 month - 1 year.
 
I'm fairly sure Viewsonic and LG have monitors in the works based on the same panel that's in the Acer and Dell (Alienware) monitors now. We haven't heard much so unless they surprise us like Dell did I would expect a longer wait than 2 months.
 
Is there a reason why we haven't heard such news? Is it not possible or practical yet to produce 120hz large sized monitors? I am interested in the current 120hz monitors but also spoiled by the size of my 28" Hanns-G HG281 monitor, especially for the price of $300. I dunno if I could "downgrade" to a much smaller monitor now. :)

I'm sure the first batches of 28" 120hz monitors wouldn't be cheap like I paid for mine. I guess I have a while to wait then, huh?
 
I am no display expert, but IIRC, the problem is with 26+ inches is the resolution is so high, that the actual DVI cables do not have the bandwidth to do such high resolutions at 120hz.

I think on the samsung 2233rz thread someone was doing the math of how much bandwidth some of the high res 26+ inch lcds would need for 120hz.

I could be way off base, but I am too lazy to look for the old thread. someone more knowledgeable than I will come along soon.


EDIT: I think this is what I read

This guys post

Most marketing folks probably don't care about 120Hz. It's easily doable on 1920x1200 with dual-link DVI.
 
There has not even been a rumor about a 1920x1200 120Hz monitor, and with the monitor industry's recent tendency towards 1080p, whether they ever do so is very much in doubt. My math in the post linked above suggests that it can be done over dual-link DVI, but it does come very close to maxing out dual-link DVI's bandwidth (and perhaps my math or my understanding of how it works is imperfect). Running any higher resolution would need some other cabling solution, and there is a significant problem.

HDMI 1.3 and earlier can't do it. I have heard that HDMI 1.4 is supposed to increase the bandwidth, but the wikipedia article on HDMI doesn't seem to directly say that (perhaps I am just missing something). HDMI Type B would do it nicely but has never been seen in any consumer device. Displayport 1.2 doubles the bandwidth of previous versions and would allow it. But both HDMI 1.4 and Displayport 1.2 seem to have been slow about getting into consumer devices, and I'm not sure if any video cards support it yet.

Edit to avoid confusion: the second paragraph refers to running 120Hz at resolutions higher than 1920x1200, for example 2560x1440 or 2560x1600.

Basically to do higher then 1080p you need display port, until that's common monitor makers aren't going to bother because they'll restrict sales too much.

With bandwidth limitations the resolution is all that matters. You can have a screen the size of a football field but as long as the resolution is around 1080p dual-link DVI can drive it at 120Hz no problem. There's no reason we can't have larger 120Hz screens but AFAIK there's just one panel in production now so everything will be the same size for a while. You do get more profound color shifting with larger TN panels but the market doesn't seem too concerned about that so I wouldn't count on that halting production. You can always wait 30 years or so until display port, OLED and 120Hz are commonplace.

My math says 1920*1200*120*24=6.6Gb/s, which is 84% of DL-DVI's 7.9Gb/s. A DisplayPort variant should also have no problem with that. I doubt the video card would have a problem, since the interface designed for needs to meet bandwidth specs. I think the only barrier is monitor companies' marketing which drives R&D, and the fact that DL-DVI cables cost more.
 
Well I think the reason for x1080 and not x1200 is simply due to the market would like to convert to 16:9 fully so they can charge roughly the same while saving some manufacturing costs. It's easier to convince/force people whit changes with some new tech/feature from start, rather than convincing people with already 1920x1200 monitors (you know how in general people are resistant to changes, and I can ofc also see a bit why in this case). So now if you want a higher res 120Hz display than 1680x1050 your only pick is 1080P, take it or leave it. I'm like 90% sure this is the reason why we might not ever see a 1920x1200 120Hz LCD and will help them to persue a conversion for 16:9 even for 60Hz market, the more 16:9 displays pumped out the easier and faster it'll get. Sad but that's how it is. 1920x1200 will probably exist as a viable option for 60Hz displays yet a couple of years (maybe 3 to 5 years) but it'll probably get more and more less common. I also expect LED backlit LCDs to mainly be released as 16:9 format. OLED if that's taking over in future, will probably start with 16:9 as a standard even.

I just wish they'd make 70Hz LCDs--still within SL-DVI bandwidth but a big improvement in mouse cursor smoothness and 70fps in FPS's. But I don't expect manufacturers to make what I really want, as they favor 1080p over 1200, TN over IPS, input lag, and 60Hz.
