I realize there aren't any monitors available yet capable of 2560x1440 @ 120hz. Does anyone have any idea when this might be available? Years? Months? I've tried researching this very question, but I can't find anything. I was hoping someone out there might know something. I'd like to get this kind of monitor and I'm willing to wait for it. Also, I don't mean the overclockable korean monitors. I looked into that and decided against it (unless someone has some hands on experience to share that might persuade me otherwise). Thanks.
I'm waiting too. The 1080p virus has saturated the industry and stagnated innovation in desktop monitors for years now.
You can "overclock" certain variants of those Korean monitors but that's about it (and I agree - not worth it).
You can bet that when someone finally does release one of these, it will be at least $1000. I'm betting we're 2 years out from seeing one but your guess is as good as mine. I don't think it will happen until Apple's "retina display" fad/tech/idea starts to make its way to desktop monitors.
I don't know how well it would work. One major concern is the GPU power needed to run that resolution and get 80+ FPS to make the 120hz worth it. I imagine you'd either live with upcaling, or lowered visual levels, which might not be bad.
IMO the bigger deal is getting an IPS panel with no ghosting, and the best way to do that would be to have a 120 Hz panel. Currently there's no 1440/1600p IPS panels that are great for gaming - certainly not for their price.
I guess they could always do a 120 Hz 1440p TN panel but that wouldn't interest me for the reasons you stated... a cheap 1440p 60 Hz TN panel might be worth a purchase though... I could see spending $200 on that.
The only current solution is Overlord monitors out of So Cal. They use the same IPS panel the Yamakasi Catleaps (and others) do, but with a PCB that allows OCing.
You can pay an extra $25 and get a pixel perfect check that guarantees perfect pixels. Oddly enough though, they say OC models are "120Hz capable", yet use the disclaimer that only 96Hz performance is "assumed" with OC models, and that achieving a refresh over 60Hz is not guaranteed. Saying even further to OC "at your own risk".
"Refresh Rates: We check each model, SE/ME/OC, to determine max refresh rates. We base our tests on the 65hz/72hz/96hz rule - that is we assume that rate for each model SE/ME/OC. Refresh rates above 60hz are not guaranteed. Overclock your monitor at your own risk."
This seems rather suspect advertising to me to say "120Hz capable" yet guarantee only 60Hz on a display you've payed almost $100 more to get 120Hz capable refresh.
