I can confirm with first-hand experience that you don't need a patch if you get the right mini-displayport to hdmi adapter. I use the one referenced here: https://forums.macrumors.com/showthread.php?p=17763899#post17763899 without any issues at 3840x2160 @ 30Hz.

Great news! Question, though: I've read that the trick with 4k on DisplayPort is that it using MST (Multi-Stream-something??) so the computer sees it as two 1920x2160 displays. Is that the case with Mac / 10.8? If so, do you have the weirdness of the Menu Bar and Dock being on half the screen?

Thanks,

David

I'm running it connected to the current 15" retina mbp. Plugged the display in via the aforementioned miniDP->HDMI adapter and it just works. 3840x2160 is the only resolution I can select, although I haven't messed with switchresx to see what other resolutions are possible.

No menu bar weirdness, other than it looks a bit weird because the menu items are so far over to the left edge; i.e., the display is so wide that an app window on the right half of the display will have it's menu items on the left side. I wish apple would just give up on the whole global menu concept and dock an application's menu to that application's window like just about every other OS does.


Edit to add:

On a related note: does anyone know if it's possible to center the application menu in the menu bar? In other words, rather than having the application menu items left aligned in the menu bar, I want them centered:

current:

Code:
Apple AppMenuItem1 AppMenuItem2 AppMenuItem3                                                MenuBarApp1 MenuBarApp2 NotificationCenter

better:

Code:
Apple                   AppMenuItem1 AppMenuItem2 AppMenuItem3                              MenuBarApp1 MenuBarApp2 NotificationCenter

Yeah. At least it's better than when I had 2 27" monitors + my iMac's 27" screen and the menus for a window could be 5 feet away from the window!

Don't know if you can center menus, but you can add this to make things work more like Windows/Linux. Works pretty well!

How is 30Hz working out for you?

Works fine, I use this machine for work, so no high refresh really required. Mousing is a bit inaccurate so far, but I'm not sure if that's related to a) the the vast distances the cursor is now traveling, or b) the interaction of the Logitech control center (need it for the MXRevolution) with Apple's built-in mouse acceleration, or c) the relatively low refresh rate.

NextStep, from which Apple developed OS X, had the menu bars attached the main window of each app, as it should be. This was carried over in the early betas of OS X, but the Mac fanboys screamed bloody murder and Apple went back to global menus. :( :confused: :mad:

No, this was never true. NeXTSTEP (and OPENSTEP for Mach) always had a global menu bar - it was just normally vertically oriented in the upper left corner:

The Frodo-esque journey my cursor would have to make to the menu bar is the only thing keeping me from buying a Seiki monitor.
 
Great thread guys! SwitchResX is a cool little App....I ran 2880x1800 (full 1:1) and 3840x2400 and my rMBP didn't really hiccup....I had FCP X opened up but it wasn't really rendering much I don't think. I need a 4K display to spit out to now....thinking about going to the Best Buy I usually go to (where everyone know me in the computer and camera section XD) and pursuading one to let me hook up to a 4K TV! ("come on guys I drop $2500+ with you throw me a bone!"):D:D:D:p

Side note: What do you guys run your rMBP's at? I like Best for Retina (looks like 1440x900) but its definitely not enough room for me, especially when I start FCP X :O is looks like 1680x1050 or looks like 1920x1200 better or worse? I understand the scaling concepts and that none are as easy on the GPU and what not as best for retina but is anyone better or worse? Never thought I'd say I'd be overwhelmed by resolution!

What refresh rate could you get from HDMI on your 4K projector?

I was able to output 3840x2400 @ 17 Hz out of HDMI for my IBM T221 monitor using SwitchResX.
Have you tried just 4096x2160 or regular 4KHD (3840x2160) @ 24Hz? Should work out...

Is Tom still around? Or did anyone get his patch that would be willing to share? Trying to run my Catleap at 2440x1440 @ 120hz and could use the pixel limit removed.

Well, I tried this - sort-of - and it didn't work. I bought the Accell DP-HDMI adapter and brought my 15" rMBP over to the local Sony store and they hooked me up to one of their XBR-55X900A 4k TVs. The rMBP would only let me select 1920x1080 as the highest resolution for it! Even with ResolutionTab.

Any idea what's wrong? I wanted to verify the Accell / rMBP before possibly ordering the Seiki but now I don't know if it's the computer or something with the Sony.

Thanks,

Bought the LG 84 inch 4K TV today.

Will be going through this thread slowly to get my 4K display to output video!

:D We have a guinea pig! My friend works at Best Buy so I'm trying to get my rMBP in for some fun and briefly played with the Sony 4K display (the $5999~ model) but they wouldn't let me hook it up without my buddy there. When you test it out be sure to test out different resolutions, refresh rates, etc. and if you could post pictures that'd be a great contribution to the thread :D :D I think the Sony comes with a proprietary media player that only works with Sony's but aside from YouTube and the RED Ray player anyone know where to get movies in 4K? I have a ton of 4K and 5K samples from RED Epic's and such but no full length movies (other than my own stuff which isn't exactly action packed).
 
Does it come with Spiderman, or with Spiderman?

Nothing bar a remote and six pairs of 3D Glasses.

Ordered the adapter as mentioned, hopefully it is all just plug and play, I hate looking at SwitchResX.

You got the active adapter (passive won't work), right? It just worked out of the box for me. The only weirdness I had was once, when waking from sleep, the seiki came up in 3840x2160, but osx only saw a 640x480 chunk of that, so I had a mostly dark screen with a tiny little window in the upper left. A reboot fixed that right up.

In other news, I boxed up the seiki and it's going back to amazon today. I just can't stand mousing around a desktop at 30Hz - way too rubber-bandy for me... but I'm a picky bastard. So, if anyone wants an an Accell B068B-008B-2 that I used for two weeks to pump pixels from my 15" rMBP to a 39" Seiki, PM me and I'll send it to you for .15 BTC.

Good to know ahead of time. Now the question is will the Mac with the Accell work for 4k@60Hz when all the TVs switch to HDMI 2 in the coming months.

Now the question is will the Mac with the Accell work for 4k@60Hz when all the TVs switch to HDMI 2 in the coming months.

Thats the big question for me: Will their be a thunderbolt to HDMI 2.0 adapter! Thunderbolt is 10Gbps per lane and Thunderbolt 2 will be able to double that through put by combining the lanes (not 20Gbps per lane but 20Gbps combined). It appears HDMI 2.0 is in the ball park range of a theoretical 18Gbps througput although I've heard that most of that bandwidth won't be needed and so the big deal is the upgrade from 340MHz Pixel clock to 600MHz pixel clock allow up to 6Gbps. Doing the math:
3840*2160*24bits*30Hz = 5971968000bps aka just under 6Gbps...So 4K@60Hz would be double that which what I don't understand so maybe that 18Gbps is needed since 3840*2160*24bits*30Hz = 11943936000bps or just under 12Gbps....Can a single Thunderbolt port handle 4K@60Hz? I know intel has a solution with dual thunderbolt ports running 4K displays and Thunderbolt 2 looks like itll handle it but It seams like anyone with a rMBP can handle 4K if they have the right connection to the computer and monitor...I wish Thunderbolt 2 sort of didn't exist...I mean its pretty new, hasn't gotten all the peripherals everyone wanted, is expensive and then they go and make it somewhat obsolete buy releasing another revision pretty shortly after the introduction...somewhat of bad thinking to not allow coupling the channels out of the box...I guess I'm happy with have two Thunderbolt ports but for Mac's that don't sort of sucks.... :O

Nice! Saw the picture too. That's gonna be beautiful. And yeah SwitchResX is sort of a pain but its useful. I just wish OS X offered advanced resolution options, I mean Jesus I can't even select a refresh rate for my TV without SwitchResX! When I first got checked the resolution settings on my rMBP I was sort of upset to not see regular resolution settings but got used to that being dumbed down, I just hope in the future I won't need SwitchResX, its a great little program though.

I just added 10.8.5 support and I published my work on Google Code.

It is now freely available! Documentation and download links are here:

http://code.google.com/p/mac-pixel-...mentation?ts=1381298359&updated=Documentation

Let me know if it does work or does not work for you.

Also let me know if your OS X version or video card is not supported - I might be able to add it in. AMD/ATI video cards support is likely possible, I need testers!

Cheers!
 
SO the new Haswell rMBP's explicity state 4K output from their HDMI 1.4 ports....do you think Apple will enable this for our mere mortal Ivy Bridge rMBP's? Would seam like a mean thing to not given the hardware is more than capable...plenty happy with work arounds or 3rd party stuff but native support is always great. Grr only thing I'm mad about is lack of thunderbolt 2 on my Ivy Bridge rMBP...still erks me that they didn't just have Thunderbolt support 20Gbps from the get go especially since Thunderbolt 2 doesnt really add bandwidth rather it couples both 10gbps lanes into one big 20gbps lane. Oh well at least I have two ports. Now to try 8K output! :D Kidding...

Great! I'm assuming the 650M and 750M are supported obviously? Any issues with Integrated graphics vs discrete? Not like I'd use anything other than discrete graphics for 4K output but still.
FYI, I got it working!
Sweet! Could you only eek out 29Hz? Seams weird that you couldn't do 29.97/30Hz. Either very cool! Makes me feel better about not waiting for Haswell (not like I really could anyways).
