No, it doesn't show up as an audio output. I did get it working on Windows 7 via Bootcamp and immediately disabled it. The Seiki sounds dreadful.
Got a tip for us?

10.9.4
I have a mac mini 2012 i5 that work fine when i updated to 10.9.4, but I have a brand new 2012 i7 that had 10.9.4 already installed without the patch. I tried to patch but it is not working. Any ideas? thanks

I also have a Mac Mini -- 2.3GHz i7 -- that I've not been successful hacking for 4K with the Seiki 39-incher. Like an earlier poster, the opening OSX screen opens in UHD rez, but when the actual OS starts, it returns to 1080p.
Are you at 10.9.4 also? Did you try the pixel clock patch before updating to 10.9.4? I am wondering if I should go back to 10.9.3 install the patch and update to 10.9.4
I was at 10.9.4 when I initially tried the patch. On one occasion, the resolution did appear in Display preferences, but I clicked Scale (to see what was there) and the Mac crashed and I've never since been able to get the patch to respond correctly during installation.
I've also tried a fresh OSX install with no luck.

Also no luck with 10.9.4. Patch installation does not produce errors, and everything goes as expected during the patching procedure, but the new resolutions never show up (and still can't be activated in SwitchResX).
Shouldn't have updated to 10.9.4 the other day... now apparently I can't use the Seiki with my MBA with my Accel active adaptor.
Anybody working on an update to this patch?
Thanks!

It might be a good idea to try this custom firmware (link at bottom of 1st post)

This helped me in getting the Mac to recognize the Seiki as 120Hz capable @ 1080p. It might fool the computer into allowing 4K modes too.

I can now officially confirm this patch will not work in 10.9.4.
Here is the checksum (MD5) of IOKit in 10.9.4: "2a4e9ff9efc7aacdc00b86c6e0d39fb1". This is not recognized by the patcher, which only contains built-in MD5 codes up to 10.9.3 (which by the way was: "9a86b6708569360f3156b53cc4f205d9").
What happens when the patcher is run is that it simply does not do any replace command because it does not find a matching MD5. Instead, what you're doing if you run all the commands in 10.9.4 is replacing the signature on your existing IOKit without actually modifying it at all.
The patcher is supposed to say: "Detected unpatched IOKit on 10.9.3, patching." It doesn't say this. It also doesn't say "Detected patched IOKit on 10.9.2, no action taken." It simply says nothing because it does nothing because the version of IOKit with 10.9.4 is unrecognized.
The conclusion: the patch does not work, and will never work, on OSX 10.9.4 or up, unless it is updated for the new IOKit.

Mavericks?
I followed the directions that dmayle posted and created an updated yosemite patch, but it doesnt seem to work
I wonder if they added more checks in the system somewhere:
https://github.com/vinc3m1/mac-pixel-clock-patch
Also to GabeA: since the file should be the same between 10.9.3 and 10.9.4, you should be able to run the command in the file from terminal:

sudo touch /System/Library/Extensionsi also tried to get it to work on yosemite, but it did not work for me either..
is this patch also for display port? i don't see why not.
if i use switchResX it sais the 4k resolutions are invalid.
i also resigned the IOKit, so the system would not reject it.

I did just that last week. My Mac Mini Core i7 2.3 GHz running the public beta identifies a Seiki SE50UY04 as a "30.5-inch 1920x1080p" TV. With the 165 MHz pixel clock limit removed I'm able to get 3840x2160, via a DP to HDMI adapter, running Mountain Lion. In each instance, the Mini starts up at UHD resolution, but switches to 1080p with Yosemite. I've also tried running Windows 7 via Boot Camp on the same machine at 4K with absolutely no problems.
The file doesn't seem to be the same. The checksum of IOKit is completely different and the jumps are in totally different places and forms (no JNE in the line it claims) than the original patch description states. Are you sure this assumption is safe? What happens if I fry my file (how do I restore the .bak file?)
oh they're that different? I patched mine on 10.9.3 and the update didn't break anything so I assume the file didn't change.
I used this updated script on 10.9.3: https://code.google.com/r/linzhu0127-port/source/browse/macPixelClockPatcher.command
The JNEs might be in different places but as long as the relative distances are the same (which I think they are) the patch should work the same. You can restore the .bak in single user mode
Yeah, I recently upgraded to Yosemite (DP7 originally, now DP8 with same results) and had my Dell P2815q (28" 30Hz 4K) working at full resolution under Mavericks. I'm stuck at 1080p now on Yosemite.. This is connected via MiniDP->DP cable.
2560*1080/60hz ultra wide via HDMI
Hello all.
I bought an Ultrawide monitor from LG with the resolution of 2560x1080. In windows the monitor work perfect, the nativ resolution is used but on OSX the max resolution via HDMI is 1980X1080/60hz. The HP probook 4540s doesn't have DVi-D dual link/ display port and I don't know how to make this monitor work.
Interesting is the fact that in the notebook specification is stated this :
DISPLAY HP ProBook 4540s:
Internal
15.6" diagonal LED-backlit HD anti-glare (1366 x 768)
External
Up to 32-bit per pixel color depth
VGA
Port supports resolutions up to 2048 x 1536 external resolution @75 Hz
HDMI
Supports direct connection to high-definition displays with up to 1920 x 1200@60Hz resolution and 7-channel audio with one
convenient cable (not included)
However I have 2560x1080 via HDMI in windows. Can this patch run on hackintosh and to enlarge also the resolutin to the native one ?

i do not think you need to modify anything.. just use switchResX to set the proper resolution. most graphics cards can handle 2560x1600 and lower, but your mac may not know about the kind of odd resolution you are using.
If I knew where to find an IOKit file from OS X 10.5.. I would be able to make one.
i'm not sure what resolution you want but a machine that runs 10.5 is most likely not supporting 4k hardware wise
What file do you need? I can send it to you if you tell me which one you need. My E-Mail is powerbookg41.83@gmail.com, please tell me yours or send me an E-Mail. I don't want 4K; I'm trying to overclock my PowerBook G4's internal LCD past 60Hz and the driver limit is not letting me past 85Hz.
please do not post your mail if you do not want spam..
Is that display capable of going over 60Hz? i have absolutely no idea how the PPC instruction set differs from Intel, so keep in mind if i will be able to make it, i'm not sure if it screws up anything inside your computer.
/System/Library/Frameworks/IOKit.framework/Versions/A/IOKit < I need this file, get it to me in some way, and ill do my best.
It has been running at 85Hz for a few weeks, so it should be fine. Please help me with this. What files do you need to have in order to write a patch?
