Hi guys,

at first i want to thank you all for the awesome Site. This helpful and genius forum is one of a Kind.
I Get managed to build my own Macintosh without any Problems and no clue what i am doing. Its pretty nice explained so i got it as a full noobie to run..

I am recently doing a new Update to el Cptn with Clover, everything works well.

Now i got some new 4k display/TV(LG 49UF6409) and not get manage to work it with the 4k resolution or more then full Hd. they showing me only the 1080p resolution choose and call it under about the System/monitor a 30,5inch lgTV.

I was looking for the other hd4600 related Threads to get out more then full HD, but this solution from rael11 sounds best to me so i wanted to try it

I know the motherboard supplies only 4k at 24 hz on Hdmi but this thread gave me some hope to manage at least 4k at 30hz.

So, i want give it a try...

First Problem i cannot found the .kext file to patch it /System/Library/Extensions/AppleIntelFramebufferAzul.kext

any help and suggestions?

Thanks 4 your help-the german noobie

Hey rael11 thanks very much for this!

This should be in Toleda's guide too since he already patches kext's for HD's. I had the pixel clock fixed but this resolution bothered me and you turned out to be correct on 2)

I have:
- El Capitan 10.11.1
- Philips 288P6 (Samsung I believe internally) - Optimised @ 4K/60Hz
- Z97 Board (Asus Impact VII) 4790K HD4600
- Display Port

And was long time looking for this and can confirm it works natively on 60Hz! Never got the 30Hz even work before.

I added clover config.plist as follows:

<dict>
<key>Name</key>
<string>AppleIntelFramebufferAzul</string>
<key>Find</key>
<data>AwAiDQADAwMAAAACAAAwAQ==</data>
<key>Replace</key>
<data>AwAiDQADAwMAAAAEAAAAAw==</data>
<key>Comment</key>
<string>framebuffer4K</string>
</dict>

FYI for others how to extract Base64 out of hex to use in clover kext patch (vendor perl comes handy as always)

hollas-iMac:MacOS holla$ perl -MMIME::Base64 -e 'printf "%s", MIME::Base64::encode_base64(pack("H*", "0300220D000303030000000200003001"));'
AwAiDQADAwMAAAACAAAwAQ==
hollas-iMac:MacOS holla$ perl -MMIME::Base64 -e 'printf "%s", MIME::Base64::encode_base64(pack("H*", "0300220D000303030000000400000003"));'
AwAiDQADAwMAAAAEAAAAAw==

This method does not require binary patching of kext itself given you have glover.

I also have BIOS setting where I can give "dedicated" memory to GPU, I have that at 64MB. It can be set auto as well but have not tried it.

Nice work titus42, I think this makes the patch accessible to many more people.

 

[Grand-G]

so if i am getting it right i changed the mac pixel clock and change the clover config.plist and then should it work?

 

[rael11]

Yes, there is nothing else that needs to be done. Some people have tried to get the icon-based resolution selector like you see on genuine Retina hardware, I don't know what that involves, but that's just cosmetic.

 

[MadBlue]

Tried this, but it had no effect on my System...
Just add exactly this lines in to the KextsToPatch-section? Have to make any changes? Add any Kext or something?

 

[rael11]

Usually it's just two things: the "mac-pixel-clock-patch" (a script to run) and the patch to AppleIntelFramebufferAzul. It doesn't matter which order you do them in.

Keep in mind that the full space of possible CPUs and motherboards hasn't been explored, so, hopefully it's still a worthwhile experiment for you.

Windows user here, and first-time poster. At work, I'm using Intel 4400 graphics to drive not one, but two Seiki SE39UY04 monitors at 3840x2160 @29 Hz. By directly, I mean without resorting to a USB-to-graphics dongle. I'm sharing the following screenshots and photos in case they might inspire someone in the Mac world to find a way to drive two 4K displays on a Mac that uses Intel 4400 or better.

My dual-4K setup as seen by Resolution Manager in Windows 7 Enterprise:



same window, together with a screenshot confirming that I'm using Intel 4400 graphics:



same setup, as seen under the Intel HD Graphics Control Panel:



The CPU in my laptop, an HP EliteBook 850 G1 with 16GB of RAM:



The dedicated docking station that makes it possible to drive two 4K monitors without resorting to a USB adapter: the HP UltraSlim Dock 2013 D9Y32UT#ABA. The two DisplayPort 1.4a ports can be seen immediately to the right of the RJ-45 Ethernet port:



The Plugable 4K active adapter that connects each HDMI cable to a DisplayPort on the HP dock:






And finally, my dual Seiki SE39UY04 monitors:




The top SE39UY04 is secured to a Chief KTB-230BK (black) dual-monitor stand...


...using a Monoprice 200mm VESA universal adapter:


Soon, the bottom Seiki will be mounted on the Chief stand, too.

Well, based on my experience, with my use cases, I would find it uncomfortable to use two 39" monitors at the same time. So count me uninspired.

Actually most of my use cases are best met by the 5k iMac, and I think resolution is also the bigger deal for most other people on the forum based on the popularity of 4k monitors that are under 30 inches.

What do you find is the best application for using such a large amount of (physical) screen space?
