    Here's a photo of a Seiki 50" Ultra HD (4K) TV running in HiDPI (retina) mode off my rMBP:

    Only problem with using it as a monitor is the slow max refresh rate of 30Hz. The mouse jumps across the screen and theres a lot of tearing when moving menus around. This is a limitation of HDMI 1.4a that only supports a max of 30Hz at 4K resolutions.

    it's really that bad? do you have one of the new rmbps? i thought 30Hz would be ok for video and normal computer use, just not games?

    The HiDPI mode looks great. I'm trying to do the same thing with a rMBP and a 39" Seiki 4K, but I'm unable to get this to work - I can only get the native 3840 x 2160, not the 1080p HiDPI. Are you using Mavericks? Can you post details of how you got this to work?

    I would wait if I was you. 4K displays will get much cheaper and much better over the next 3 years. You gain very little by being an early adopter at this stage.

    I picked up a cheap TB display on the cheap thinking it would be great.

    Not that impressed with 1440P due to being spoiled by my Retina15.

    I will use the TB for a year or so and hang on to this macbook until I can replace the whole set up for a competitively prices 4k external and whatever macbook supports it at the time.

    Way to expensive now, esp for my purpose of use. Heck I didn't even need the TB display.

    600 for one just purchased and never used. He just missed the return date and needed the cash.

    Apple seems to have refreshed the box? This came with the MagSafe two adapter.

    Definitely a sweet deal. Sounds like you have the newer stock since it came with the MagSafe 2 adaptor.

    That's odd. I'm using the 39" version right now and don't see any cursor lag or tearing or artifacts when moving windows. Could the 50" not be as good as the 39"? It is a bit older. Have you updated to the latest firmware?

    I just got a LG UHD TV, but cannot get HiDPi mode on it other than 960x540. :(. Tried SwitchResX but no go. I think I can live with 30hz, but running at the native resolution (3840) is killing my eyes. :mad:

    Can someone confirm if 10.9.3 supports 4k/60Hz over HDMI? Mac Pro or rMBR.

    I have a nMP and 4k@60hz over HDMI is not working. Display is LG 65UB9800 with HDMI 2.0 ports. HiDPi isn't working either in 10.9.3 beta. :confused:

    EDIT: Got HiDPi working by holding down Option while clicking "scaled" in Display pref.

    4K/60Hz works with the 2013 rMBP and nMP running 10.9.3 beta over Thunderbolt/DisplayPort. 60Hz is not possible over HDMI because both machines have HDMI 1.4 ports, not the newer HDMI 2.0 required for 60Hz.

    2560x1440 @ 60 Hz possible?

    Does somebody here know whether it's possible to run a 4k display at 2560x1440 @ 60 Hz? I got a 2012 rMBP. 4k just works at 30 Hz, which is way too low.

    Thank you!

    As far as I know, you can only have 4k at 60hz running through the DisplayPort 1.2 (or Mini DisplayPort or Thunderbolt) on the new Mac Pro or late 2013 15" Retina Macbook Pro. Oh, and running Mavericks 10.9.3.
    Also, your monitor should have the 60hz refresh rate.

    The HiDPi mode is implemented in the 10.9.3, which should be released to the public really soon.

    Thank you! So maybe I'm gonna buy a 4k display like the Samsung u28... or the Asus PB287Q and just run it with 2560x1440 until I got a new Mac. Thanks!

    I'll get the Dell UP2414Q, good size, 99% adobe RGB, 4k 60hz and the price is also good.

    Anyone can join the Appleseed program and download the 10.9.3 beta. I did it. I don't have the latest rMBP or new Mac Pro or a 4K monitor. But if someone does I would think they would want to get the beta and try out 4K at 60Hz.

    Tried Quad HD, but coming from a Retina it just wasn't the same. Have to go 4k to get anywhere close to retina quality.
