    Apple today updated its 4K display support page following the OS X 10.9.3 update, detailing the enhancements that have been made to 4K display support.

    Running OS X 10.9.3, the 2013 Mac Pro and the 2013 Retina MacBook Pro now support several new 4K displays, including the Sharp PN-K321, ASUS PQ321Q, Dell UP2414Q, Dell UP3214Q, and the Panasonic TC-L65WT600. Previously, only the Sharp and ASUS displays were officially supported.

    There's a new section on display adjustments and Retina scaling, introduced to allow the resolution of 4K displays to be adjusted much like the display of the Retina MacBook Pro, improving the size and readability of text and other on-screen elements.

    The revamped support page also notes that both the Mac Pro and the Retina MacBook Pro are now able to support 60 Hz 4K output for the five supported displays, using multi-stream transport, a feature previously limited to the Mac Pro. With the higher refresh rates, response times for tasks like game playing and video editing will be improved. Detailed instructions are given for enabling the option:
    First released yesterday, OS X 10.9.3 with enhanced support for 4K displays can be downloaded via the software update tool in the Mac App Store.

    No official Samsung U28D590D support? Arguably the most popular based on its price.

    Do these only work on the newest Mac Pro and Retina MBP because of the Thunderbolt 2 support? Can one not push 4K over Thunderbolt (1)?

    looking more and more like a retina imac release this year. Will probably be the 21" version. Old 21" version will be the cheaper version.

    Just don't try more than 2 monitors!

    Lots of issues supporting more than 2 monitors (of ANY resolution)

    10.9.3 broke support for more than 2 monitors for Many people.

    I just got, and the same day sent back my UP2414Q.

    Screen is fantastic, but the input lag is terrible, it feels like the mouse is stuck in molasse. I tested it with this device:

    http://www.leobodnar.com/shop/index.php?main_page=product_info&products_id=212


    And it was around 33ms without game mode, closer to 20ms with, but you lose all calibration option by using game mode... :(

    I hope Apple (Or anyone, I don't really care) make a 4k display that is as nice to see as it is responsive.

    I'm not sure what the input lag is on the iMac, but at least I don't feel any delay when I move the mouse.

    Looking like Thunderbolt 2 as the key, then.

    Kind of astounding the amount of bandwidth involved.

    Did you enable DisplayPort 1.2? Its disabled by default and you're stuck at 30Hz.

    You can push 4k over TB1, just not at 60hz like this update adds on TB2 computers. TB1 is limited to 24 or 30hz at 4k

    I did, I also tried with a PC that is display port 1.2 capable, input lag is caused by the processing inside the monitor. Input lag has nothing to do about refresh rate, it's the time between when the monitor receive the signal and when it display it.

    Quote from TFTcentral about input lag:

    Input lag is not much concern when you use your monitor for browsing/working/photography, but is very annoying when gaming.

    This article indicates that the 60hz support was just released, so I guess my indirect question remains: is Mac OSX itself fully compatible with 4K displays over Thunderbolt (1) as long as you're in 30hz mode, or is it still only limited to the Mac Pro and rMBP?

    Ok now I'm confused. Previously, Macrumors reported that 60hz support in 10.9.3 would only apply to the 15" Retina Macbook Pro. Now its just saying "Retina Macbook Pro". So does this apply to the latest 13" model or is some information being left off?

    I was hoping it would come at WWDC, but then why not wait to release 10.9.3 until then? So I don't think it's coming anytime soon. If not, why? Are there no panels that meet Apple's standards? I'm genuinely curious as to the holdup.

    You can't effectively displace 27" with a 4K 21". 24" is probably the smallest practical size for the top imac.

    I don't think they will make a 4K display. They need a 5K display with the current tech or otherwise we'll have giant UI elements. That, or they need to update the OS for more resolution independence. The scaling method puts too much extra work on the GPU and the CPU.

    Does anyone know what happens if you plug one of these displays onto an earlier Mac than the ones listed on that page? Like my 2012 iMac?

    Will I get 4K resolution @ 30Hz? or will it not work at all?

    The iGPU (integrated graphics) that Intel offers currently do not officially support above 2560x1440 which may be the problem.

    In the past I have connected a monitor with higher-than-officially-supported resolution to a Mac with just fine. As both Ivy Bridge (HD4000) and Haswell (HD4200-HD5200) access up to 1.7GB of system RAM for graphics, there should be no problem with displaying 4K, unless the system disallows it.
    There are Windows laptops with Haswell iGPUs running >1440P screens. Maybe the refresh rate is reduced, and perhaps Apple doesn't want "reduced refresh rates to ruin user experience" but there is no technical reason why, given 1.7GB memory and Thunderbolt 1's bandwidth that other Macs introduced since 2012 should not be able to push a 4K monitor.
