I am doing a bit of research.. what I find out it's probably not good.
simple question.. will the dvi dual link be able to transmit 2560x1440x120?
simple answer: NO
it doesn't have enough bandwidth.
we know that the single link provides a maximum frequency of 165MHz pixelcycle. so the maximum bandwidth of DVI dual link should be around 330MHz.
2560x1440x120 = 442,368,000 Hz = 442MHz > 330MHz
therefore the cable wont be able to drive the drive at full 120Hz
the 330MHz DVI dual link will bottleneck at around 89Hz (still not bad).

please tell me I'm wrong sadsmiley.gif
 


 

Sorry but you are not wrong. Maybe they achieved higher refresh rate by lowering resolution.

-Durable monitor frame/back/case with stronger materials (like the crossover): up to ~$25 extra I'd even pay up to ~$50 extra if it includes a better stand
There are other things I might like (better stand, easy usable vesa mount, etc) but I do not think I would pay extra for those... they would be just frosting on top.
Agreed. thumb.gif
Also, 650 people interested already. The interest ramps up quite quickly. smile.gif

Also, A monitor priced at ~500 (they would never sell these monitors for the same price as the Korean manufacturers) would kill there sells of there 1400+ monitors.
Once you stamp a brand on something your views and expectations about that product change. There is a reason these big company's brands are worth BILLIONS.

Well, Dell could easily put the screen on their Alienware side of things.

That's the spec for DVI.

But Intel i7-2700K processors are only specced for 3.5 Ghz operation wink.gif In any case, I can drive my monitor at 2560x1440 at 116 hz.

Wow that's really amazing gaming on 2560x1440 @116Hz on DVI-Dual-Link thumb.gif

Dual Link DVI is only limited to the capability of copper.

You can assume it's infinite until we need to use better metals (the new copper alloy etc) smile.gif

Single-link DVI had a mandated limit of 165MHz pixel clock. Dual-link DVI (and I believe HDMI as well, although it's single-link) do *not* have a mandated limit, so it's whatever your card, cables and monitor can handle. This in most cases appears to be above the naive limit of around 90Hz or so; as HyperMatrix has shown refresh rates of 120Hz and higher are possible with the right hardware.
