Because HDMI 2.0 basically doesn't exist yet. Sure, the standard was finalized around September 2013, but compliance testing appears to still be in progress (HDMI's official website says it "should be done by the end of 2013", but that hasn't been updated) and there are no compatible devices available at this time.

What happens when the firmware magically never appears but they have new models out sporting "full HDMI 2.0 compliance"?
Which raises the question: are the new models, released before HDMI 2.0, using HDMI 2.0? Apple has done this with "not finished" specs in the past, but they had full support at launch. Seiki is saying "we are going to release a model with HDMI 2.0, but it won't be enable until sometime in the future."
If, they have HDMI 2.0 compatible hardware, why is the software (firmware) not able to offer the full specs? If there is a problem with their firmware, why both releasing until you can launch with full specs.
Would you buy a car that says advertises "200hp engine, but only able to be 100hp until an upgrade to the computer controlling the engine is released at some point in the future."? I think not.
Found some more info about the Samsung on a Russian site:
http://gagadget.com/desktops/2014-0...itor-samsung-u28d590-s-razresheniem-ultra-hd/
With the help of Google Translate:
Samsung announced its first resolution monitor Ultra HD ( 3840h2160 ) U28D590. Diagonal of 28 inches , used TN- matrix mapping one billion colors , viewing angles of 170 º and 160 º horizontally and vertically , respectively. Maximum Brightness - 300 cd/m2 , the static contrast - 1000:1 , pixel response time - 1 ms.
Interfaces: 2hHDMI , DisplayPort and audio . Power consumption - 32 watts. The monitor supports image scaling (UHD upscale) to resolutions of 3840x2160 and the " Picture in Picture " (PIP 2.0), thanks to which you can display the images in the second with a resolution of 1920x1080. Supported simultaneous connection of two computers and mode Game Mode, optimizing the monitor for gaming. Dimensions : 660.9x486.3x169.4 mm, weight : 5.65 kg. In the sale of Samsung U28D590 arrive in March for 25,000 rubles or 6050 UAH .
At least it's a fast TN, and now we have price (~790 CAD or ~710 USD). Also seems to confirm the existence of an upscalar. March release date.
I don't see a mention of refresh rate, and the $700-$800 price range seems to be exclusively the domain of 4k 30 Hz. Can anyone confirm?

There is not any HDMI 2.0 "sink" hardware currently available. I don't see how they can firmware this away; HDMI 2.0 means the sink has to run at an incredibly high clockspeed (by HDMI standards).
No, not really. DisplayPort doesn't mean a thing unless there are 2 TCONs (and the necessary splitters) present. You can most certainly have a 4K display with a DP input that only does 30Hz.

The original article from pcmonitors had this:
"The panel used is TN (Twisted Nematic), which is capable of running 60Hz at the native 4K resolution over DisplayPort 1.2. This contrasts with some other models, such as the Dell P2815Q, that appears to be restricted to 30Hz at native resolution."
Also, you can read it in the press release:
http://www.samsung.com/uk/news/loca...owcases-latest-consumer-and-business-monitors
They mention a scalar "UHD Up-scale". Might be an interesting option after all (even though going from IPS to TN will be hard).
You do notice I said "should". I've never seen a monitor that used displayport without at least supporting 60hz. Why would they bother with Displayport for 30hz? I'm not saying it can't be 30hz, only it most likely is, or the Displayport was pointless.

How's the displayport pointless? They don't have to pay a licensing fee for it as they do with HDMI.

And just to add to that, Dell's P2815Q is limited to 30Hz even though it has DisplayPort.
They already have HDMI on it, there was no point in adding Displayport if they weren't going to use it for some purpose. I guess there are exceptions, but as mentioned above, this is not one.

The 30 Hz 4k 28" Dell is already on sale for $630. I hope they hurry up with cheap 60 Hz models.

That seems really cool...Let's see how it compares to the other available monitors!
I just googled HDMI 2.0. It only supports 60hz at 4K. So we waited 12 years for this? 4K is finally arriving on monitors, TVs, online content, video cards etc... And we are still stuck at 60hz. What a complete and utter waste for progress.
With HDMI 2.0 we are stuck at the refresh rate that gave us migraines on CRTs in the 90s and that gamers for the last couple of years have scoffed at with their 120++hz 1080/1440 monitors.
Color me extremely disappointed.

These are 4k displays. If you want to do 120Hz @ 1080p go right ahead. You're not going to get 120Hz @ 4k, not for a long time.
I just bought the Samsung 4k display off eBay. I'll post my impressions when I get it.

You can't compare LCD 60Hz to CRT 60Hz. CRT redraws the picture one line at a time and hence low refresh rates gives you intense flicker. LCDs just stay on so there's no flicker at 60Hz.

The flicker is not the point, its just an example to explain the lack of progression. Gamers preferred higher refresh rates even in the late 90s, and now 4K is coming along with a brand new HDMI standard that absurdly lacks support for more than 60hz.
The point is, LCD's don't cause headaches. The vast majority of people play at 60hz. The new HDMI 2.0 spec supports 120hz, just not at 4k and it now supports 4k at 60hz. It is a nice improvement, non the less. This means that HD3D TV's may start supporting 120hz on PC's as well.
HDMI is a TV connection anyways. While it works on PC's, HDMI follows the needs of TV's. DP follows the needs of PC's, as DVI has.

Is lack of 120Hz at 4K super frustrating? Yes
Is it absurd? No. do you think they can just flip a switch and make the chips you need to handle that data double in speed/capacity? That's like saying oh, we'll just double the lanes on your local freeway overnight and hope all the cars and drivers can handle 150mph
