From Apple site - there is only one model currently available that is listed as supporting 4K (that includes 2160P - 3840x2160) at 24fps - namely the 15" retina mackbookpro (LATE 2013! model).

The 13" rMBP Tech Specs also show it as supporting 4K at the same resolutions and frame rates as the 15".
 
Seiki 39in 4k

I just got one of these as well. After a few hr of testing here is what I found.

Works 'out of the box' at 4k with late 2012 rMBP via Accell adapter at 30hz For photo editing, this is just fine as nothing moves fast. For video editing its fine as well, but cant' see anything at 60p in real time if dealing with 60p footage.

On a Macbook mini mid 2013 i7, it only shows up as 1080p both on default HDMI port and via thunder port using Accell adapter. I have not been able to get the Mini to see it at full res.

There seem to be no reports that I've seen that detail getting it working at full res. Several people have comments like "Works great on my Mini" with no technical details so they may be 'ok' with 1080p

I have managed to screw up the settings on the mini using switchrex now to where it doesn't recognize the monitor at all :) so will need to try and reset everything to factory on video settings.

If anyone HAS gotten this to work on a 2013 Mini (intel 4000) at full res, please post details!
 
Anyone can test in 2013 late imac ?

It suck don't come with thunderbolt 2 ...... but oh well
 
I just got the 39" Seiki and I have a late 2011 17" MacBook Pro with mini-DisplayPort.
I have the Accell adapter on order

While waiting for the other adapter, I just tried a Unitek Y-6301 active mini-DisplayPort to HDMI adapter.
The Seiki came up as 1080p 60Hz, but in System Preferences -> Displays, 3840x2160 shows up in the list of available sizes. When I select it, the Seiki goes blue and never comes up.

Anybody have suggestions, or should I just wait for the Accell MDP->HDMI adapter?

Thanks!


You don't need a haswell mini (though it'd give better graphics performance). Theoretically the HDMI port on the current mini is supposed to be high-speed, but driver-issues seem to prevent 4k resolution except at low frequency rates.

Easiest way to do this is with an Accell B086B-008B-2 adapter plugged into your thunderbolt port. That will give you 3840x2160x30Hz. With my Seiki 4k, it works out of the box on my 2011 mac mini. Some other users have found they needed to use switchresx to make up a mode for their TV's - not sure anybody has tried a sony set yet.

From a google search, its not clear the Unitek can support HDMI 1.4 data-rates - I see the max res listed as 1920x1200, which would be about half the required bandwidth. Sounds like the Seiki isn't getting a good signal through the adapter.

I'd expect better luck with the Accell - when I looked during the summer, it was the only active adapter I could find that claimed HDMI 1.4 compatibility.
 
Ok.
Thanks for the response!

I guess I just have to wait until Wed for the Accell to arrive. :-( I searched around locally for one of the Accell units for sale. No luck!

Thanks!

2012 Mac mini HD4000, with mavericks 10.9, and switchresX works with seiki 4k tv

i can get 4k@18hz using only hdmi from back of mini to hdmi of the seiki tv

i tried emailing "tomthemacuser" to remove the pixel clock but he hasn't replied yet, i think with the pixel clock removed i can get 30hz

also i did NOT need to use the Accell B086B-008B adapter, but only got 18hz using hdmi to hdmi

with the adapter maybe you can get 30hz with switchresX

if someone can please test with 2012 mac mini+adapter+switchresX that would be great

----------

The HDMI port on all Macs is single-link so you won't get anything above 1920x1200. You need DisplayPort to get 4k resolution, and right now there's no way of doing that with Macs.

this is INCORRECT i can output 4k@18hz from the hdmi port of a 2012 mac mini using switchresX

can you try using a 2013 mac mini + accell adapter + switchresX and see if you can get 30hz,

in switchresX you have to select ur monitor, then custom resolution, then select CVT-RB, then put in 3840x2160, and then 30hz at the bottom, then u have to restart, and go back into switchresX and select the new setting, it usually won't automatically go into 4k when u restart
 
Success with Seiki 39" 4K in Linux! Beautiful!

While waiting for the Accell miniDP->HDMI adapter to arrive, I built up a Ubuntu Linux box this morning with a GTX-680 graphics card and hooked the Seiki 39" to the HDMI port.
I updated the system and installed the NVidia accelerated Xorg server.
It was still coming up 1080p and not showing 3840x2160 as a display res choice. I created a config file with an adjusted modeline and it worked!

It is _BEAUTIFUL_!

I think the Seiki 39" is going to work nicely as a primary display or I might put this display in between my 2 30" 2560x1600 cinema displays.

At my work, we have a couple Toshiba 4K 55" monitors that we bought several years ago for working with SDO and other solar image data. The Toshiba displays are very nice, but you have to drive them with 2 dual-link DVI inputs (easy to do) and they cost almost $30000.00 each when we got them..., so the cost per pixel is quite a bit lower with the Seiki.
 
switchresx and radeon laptop graphics card for 4K

Apparently switchresx is enabling 4K on my 2011-12 17" macbookpro but the Radeon card driver is not supporting. One of the gurus on this forum told me the nvidia driver was modified on various models to also allow 4K, but that has not been done for the radeon card in this laptop. Just want to preview 4K 24fps (2160P) on seiki 55".
Any Radeon hackers out there? Is it a big deal? Would you be willing to help? If I motivate you$?
Thx

curious, did you have any luck with the accell adapter w/ the 2011 mbp 17" ? have a similar setup.

Yep!
The Accell active adapter works just fine with my late 2011 MacBook Pro 17", as does my MacPro 5,1 with ATI Radeon 5770.

I would recommend just sticking with the Accell adapter:

I also bought another MDP->HDMI adapter from eBay that claimed it did 4K, but no go on that one...

4k pixel clock patch

Hey guys... I posted this in one of the other threads, but I just got the Seiki 4k 39" to go with my mini. I'm running Mavericks, so I'm limited to 17 Hz without a working pixel clock patch.

Does anyone have copies of both the original and patched files from an earlier OS version (the script saves a .bak file automatically, so they should both be there).

I'd like to try to understand what the patch is doing so that I can create a version that works in Mavericks.

Thanks!
 
Any update on this? Would love to use this Seiki 39 4K at more than 17Hz. It's a little to slow for my needs.

17Hz?
It runs at 30Hz on my MacBook Pro 17" and on my MacPro 5,1

Since Costco has the Toshiba 65" 3D 4K display for sale for $3000 right now, I brought my MacBook Pro 17" with the Accell mini-displayport -> HDMI 1.4 active adapter in (which drives my Seiki 4K just fine) to try it out.

I was trying get the Toshiba to run at 4K, but it would only come up as 1080p. Higher resolutions were not available.
When I tried setting it to 30Hz (what I use to drive the Seiki 4K), the Toshiba wouldn't sync at all.

Has anybody tried the Toshiba 4K 3D display?
Driven it at 4K from a Mac?
How?
What computer(s) and adapter(s)?


For those that are interested in pretty movies/pictures of the Sun, I have basically unlimited 4Kx4K content (I work on the SDO/AIA science team).

It would be pretty easy for me to make 3840x2160 native resolution cutout movies of SDO data...
Anybody want some?

I have a Mac Mini and a Macbook Pro 17" (8,3) and can't get it past 17Hz with SwitchResX.

How are you getting that resolution (3840x2160@30Hz) on your 17" Macbook Pro? Are you on Mavericks (10.9) or Mountain Lion (10.8)?
 
Bump, any updates on this? I'm considering a Samsung U28D590D.

I have the 2.3G i7 mini on 10.9.2. Has anyone used this method to remove the pixel clock limitation on 10.9.2?
 
I'm considering a Mac Pro to run a 4K projector (when they are released this year). I think a Mini could do it, but not the current ones very well.
 
Yes please!

Please do share! Could you possibly put them up in MP4 format playable by Quicktime? It seems to have the best performance.
 
What's the maximum resolution using DP anyway without any hacks?

ie; what scaled resolution would you get if you did plug in a Samsung 590?
Or would it not drive it or drive it properly at all?
 
Thanks.
Anyone know if the latest current model Mac Mini would have any problems using that display?

My thoughts are to get a HengeDock and run the display at full resolution using my Haswell retina MBP. If I go portable with the rMBP, then I or family members would use the Mac Mini to power the Samsung 590, at a lower resolution, if there are no issues.
 
I got a Dell 28" P2815Q. This guy is 4k but will run at 30Hz. I plugged it into a 2011 27" iMac with Radeon HD 6970M 2GB running OS 10.9.2 and a Mini-DisplayPort -> DisplayPort cable and it just worked. The 30Hz thing is a big deal, but if you don't obsess over it, and you want years and years of pixels, I'd say go for it. I researched this a bunch and knew it would work @ 30Hz. I didn't do a lot of research for the 60Hz support on the OS X side. However, 30Hz displays like the 39" Seiki (60Hz with firmware upgrade?) and the P2815Q are cheap where has 60Hz support is expensive. Say hello to the 32" Dell UP3214Q for $3k!

After reading "4k is for programmers" I set up one my developers running Linux on a the 39" Seiki and he loves it. I got the Dell P2815Q to use with my iMac knowing that 10.9.3 specifically adds 4k support to have retina style 1080p HiDPI:

Buyer beware! There seems to be a problem with 11" Haswell MacBook Airs and 4k displays: https://forums.macrumors.com/threads/1646972/
 
Need a little help with 4k

So I took the plunge and got a SEIKI 4k Monitor. Hooked it up to Mac mini with HDMI, not luck. Next tried the SEIKI HDMI up convert adapter. SEIKI then worked for a few seconds and then would flicker screen off and on. Next tried with Switchres and the SEIKI adapter. Max resolution would go to 2k resolution. So I decided to try the minidsplay port 4k converter from Accell. Hooked it up but Switchres will not go higher than than 2k. So figured I would uninstall switchers and see is the Accell can get to 4k by itself. Now the problem is I think Switchres has screwed something up with my 2012 mac mini.The way I got the 4k res with the SEIKI adapter was to change display settings to 1080i with refresh rate at 24 25 or 30. Now I can't set the refresh rate, only sees 50 or 60. Weird things is when rebooting and screen pops on SEIKI says 4k resolution. So I think the Accell will work, just got to figure out how to undo what Switchres did to the Mac mini. Any ideas?
