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)
- 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:
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"));'
hollas-iMac:MacOS holla$ perl -MMIME::Base64 -e 'printf "%s", MIME::Base64::encode_base64(pack("H*", "0300220D000303030000000400000003"));'
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.
This used to work but no longer works for me under Sierra. Could someone please update it? I'm trying again to run 4k resolution with HDMI (ca 30Hz).
