I have a 39in 4k monitor that I bought for $500. The only problem is that 4k monitors through HDMI can only run at 30Hz, which is extremely noticeable. There might be a way to run at 60Hz but I haven't got it to work yet. Here's the monitor: http://www.amazon.com/Seiki-Digital-SE39UY04-39-Inch-Ultra/d...

Hopefully it will have a DisplayPort out like the U2713H or a Cinema Display. The fact that the U2713HM doesn't have one makes high-res dual displays a pain for PC laptops.

You have to use MST with DisplayPort 1.2 - sort of like Dual Link with DVI - to drive it at full resolution at 60hz.

The connector is already maxed out, so chaining is not possible.

You'll probably have to wait until HDMI is updated, and use one DP and one HDMI.

It shouldn't be long before some Korean/Chinese factory starts selling these for half price on ebay.

If I could buy one of these for even 6000 RMB in China I would get it in a heartbeat. Alas, it will take a long time for that to happen.

Any idea how new of a macbook you would need to power this? I'm guessing my 2012 13" air can't run it right?

"MacBook Pro (Retina, Late 2013) and Mac Pro (Late 2013) computers can use 4K displays and Ultra HD TVs with OS X or Windows (via Boot Camp)."

Curious: what's the 30Hz effect? Flickering on a static desktop? Or just less-smooth animation?

Even a brand-new Macbook would be unable to power this display. All currently sold Macbooks can only power displays up to 2560 by 1600; the Macbook Air can power one external display at this resolution, and the Macbook Pro can power two. (Edit: The iMac can also only power one additional display at the same resolution.) If you want to use a Mac with a 4K display, consider getting a Mac Pro, which can power up to thre…

The MacBook Air from 2012 or later can drive two 2560x1600 displays at 60fps: https://twitter.com/Antagonist/status/252936243606859777/pho... (It only has one Thunderbolt port, but Thunderbolt displays can be chained.)

While the integrated graphics on the 2013 models can drive 4k displays at 60fps, only Thunderbolt 2 has the necessary bandwidth. The latest rMBPs have Thunderbolt 2, so they should be fine once OS X's drivers are updated. Everything else is stuck at 30fps.
