    Skyworth 39E780U -- 4K UHD TV (domestic China model)

    Check out this Overclock.net review by maarten12100

    The good: Only $600.
    The bad: Difficult to order. Sold only in China domestic market.
    I *knew* for a while that these 39 inch 4K panels cost only $425 in factory quantity, so I guess that explains the unusually low price ($600) for a 4K monitor.
    Almost too good to be true, but it's confirmed -- this is the real thing!

    Now added to the HardForum HDTV Overclocking Thread, and also blogged at Blur Busters

    Need 60Hz 4K monitor under 1K. The wait continues.

    Someone is bound to hack the $600 HDTV with a new $300 DisplayPort circuit board that does 60Hz.
    We need a person like Hypermatrix or Scribby to look into this matter.
    The panel is clearly capable at being refreshed at high speeds; so it's a matter of appropriate electronics.

    Still, view this another way: This is like a 39 inch 1080p 120Hz gaming television. The 4K is just a bonus at the price.

    Why wait for a Hack when Asus is releasing it?

    The rumored price of the ASUS is over $3000 (three thousand)

    This TV, probably using exactly the same 39" 4K panel, is only $600 (six hundred), although inconvenient to buy (available in china only, difficult to buy outside, requires voltage adaptor).
    This 4K HDTV is cheaper than a Geforce GTX 780.

    Huge, massive chasm of price difference.
    So this is of great interest.

    for 4k @60hz using display port, not using eyefinity or Nvidia surround. Is worth 3k.

    Agreed. There's many organizations (and high end users) that need 4K today at 60Hz, under warranty, from a fully supported company available in major markets such as North America and Europe. No disagreement.

    That said, some of us can't afford the $3K, but definitely ~$1000.
    If someone can build a $400 motherboard for this $600 HDTV to make it 4K 60Hz (and perhaps even over one cable, but not necessarily), it could be useful.
    Just like the Overlord PCB 120Hz monitor motherboard upgrades -- it's theoretically possible for a third party to take upon this. Who knows?

    I agree, plus for all we know the Asus 4k monitor will still act like your need to run it in eyefinity/surround.

    Too bad....anyway bring on the future of gaming!

    I think 140Hz is officially the highest confirmed rate without frame skipping. (Using Refresh Rate Multitool)

    He said that 254Hz was actually running too fast for Multitool to be seen by the human eye; and I wouldn't yet trust video evidence of frame skipping (yet) -- because I know camera exposures can automatically create false frameskipping. He needs to use a 1000fps camera such as a Casio EX-FC200S or EX-ZR200. I'd love to know of a true confirm, though!

    I'd actually really like to see one of these up close in a PC-monitor capacity...a 30" 4K display would be genocide on the eyes at full resolution at 3-4', but I'm wondering how this would work out. It'd probably be nice for a main TV in smaller rooms for that matter.

    In any way there will be a flood of the catleap-like 4k monitors and that seems to be for sure! Which is great and I'd like to see something like 254hz display in person ... Although a 4k in <1000$ is also extremely tempting!
    That's why there weren't any progress in 1440 and 1600 domain for the last number of years - because everyone involved new cheapo 4k monitors were coming.

    "Beside those specs the panel gives you the option give you the ability to switch of off all the motion blur things you don't want as a gamer." so it's like lightboost? :D
    "I also didn't notice any input lagg." same.

    Good question.
    Normally that's motion interpolation, but that adds input lag.
    We'll have to ask him to do the hand-wave test (check for flicker).

    It probably wouldn't have as low blur as LightBoost, but if it has a strobe backlight (useful for crosstalk-reduced 3D) that would be quite interesting that a generic chinese maker thought of it, or copied the "Sony Motionflow Impulse" idea (Sony's equivalent of LightBoost -- only 60Hz and flickers a lot though)

    Has anyone else tried to buy the Skyworth 4K TV, at least to test as a 39" computer monitor?

    1. Purchasing is adventurous. This Skyworth 4K TV needs to be purchased through a Chinese buying agent service, such as via Taobao Buying Agent Service (e.g. like this page) [WARNING: Unverified] and other services such as these. A Buying Agent is an agent service that purchases stuff only domestically available inside mainland china & ships them out of the country to you. This can cost a pretty penny, but the TV is rather cheap for 4K. About 400 dollars for the TV plus 200 extra for agent fees and shipping.

    2. You also need to buy a voltage converter, to convert your voltage to Chinese compatible voltage (220V, 50HZ, 60 watts minimum, 100 watts recommended), since this TV does not have a universal voltage power supply.

    It is only 600 dollars including shipping, so the risk outlay is fairly low.
    Very few people are willing to be a guina pig, even though this is far cheaper than alternate $7000 4K HDTV's.
    Has anyone else tried buying this?

    If I had the expendable cash I'd probably take a chance on it (albeit including a voltage converter you're looking at, what, $650-ish total?), but alas...

    I think some people such as Vega and l88tbastard would be able to pull it off.

    Vega probably has the cash in his couch, true, but he's crazy to begin with. And he probably wouldn't stop at just one--he'd buy three and try to force the world's most insane multimonitor setup.

    I would totally get one of these cheapy 4K sets if there was a 60hz Displayport PCB available, but those are Vaporware correct?

    Pretty much, yup. A UHDTV (not a dedicated monitor) with DisplayPort? The only people who would do it are the Chinese, and nobody's gone there yet.

    Its actually looking like ASUS might be the first to do this.

    If you mean this, that's a dedicated monitor (versus an HDTV with internal tuner and so on)...unless I missed something along the way...?

    Yes, both the 31" and 39" 4K panels announced by Asus are monitors (no tuners). But they will have 4K@60Hz. Since the 39" is expected to cost ~$1000, it makes it a very attractive option for those looking to adopt 4K without paying >$3000.

    Anything official on the pricing of the 39 or is it still completely speculation as it has been for awhile now?

    Actually I was talking about the unreleased 39 inch which uses the same panel as the skyworth TV.

    Of course its a monitor. If you think a TV is going to have display port input that is probably never going to happen.

    Nothing official but it uses the same panel as the skyworth so there is no reason it shouldn't be affordable.

    "Major" manufacturer with full warranty backing and high build quality + their markups + retail markups + marketing expenditures + perceived value = much more expensive. You're paying a lot for the warranty support on panels sold in the USA... I'd be very (but pleasantly) shocked if that came in at under $1k.

    Understood. But seiki is also coming out with that panel in their own 39 inch TV later this year. It will probably be $600-700 and they are going to have the same issues. It should cost ASUS under $500 to build these things so I don't think expecting it to be < $1000 is unreasonable.

    Thats not really how it works. If it costs them 500 to make it, I'd assume it'd be at least 2k then when you factor in overhead/profit.

    But if a competitor is selling that exact same panel (with different electronic board, i.e. no DP) for $600-700, adding in brand value, warranty, etc. won't push the price up by more than $400

    Yeah I find it unlikely that ASUS would sell a panel for $2k for one that costs them $500 (if that) to make. Asus is pretty well known for making budget displays compared to say Dell. Now I would totally expect that kind of behavior from someone like apple...

    The panel appears to be the CMI (Innolux) V390DK1-LS1

    It can only do 24+30hz at 4K according to its data sheet.
