Stuck. Can't get 4K video! Max 1080p

Using ASUS SABERTOOTH Z97 MARK 2_USB 3.1 + Samsung UN40KU6300

Applied mac-pixel-clock-patch-V2 + AppleIntelFramebufferAzul.kext

Verified 4K resolution on Samsung UN40KU6300 via Intel HD4600 over HDMI 2.0 (correction HDMI 1.4a) with Windows 10 + Ubuntu

Any ideas appreciated.

Your motherboard doesn't support HDMI 2.0, but you should still be able to get 4K@30Hz.

Usually it should be sufficient to apply the Pixel Clock Patch without any further modifications.
Did you verify that 4K still doesn't appear in your display settings? Pressing the option key should reveal some more hidden resolutions.
Maybe 4K can be forced with SwitchResX?

Did you patch the connector for HDMI? (most connectors in the framebuffer kext are DP).

alexnc · May 31, 2016

RehabMan + Fl0rian,

Just applied graphics_intel_hd5k-azul-d-90_patch.command.zip

Same.

Option key on Scale, still shows 1080p as max resolution.

Did you check in ioreg to see if the connector-type is HDMI? (<00 08 00 00>, not <00 04 00 00>).

Yes, all three ports are <00 08 00 00> (HDMI) ... hence patch D.

Increasing BIOS memory (to 64mb) and framebuffer memory (to 48mb)...

alexnc · May 31, 2016

Thanks RehabMan. BIOS memory increased already to 64MB.

How do I change the frame buffer memory to 48MB (thought I already did per fix / patch above)?

Yes, 64mb in BIOS is typical. Your patch changes the framebuffer to match.

That's what your patch is doing.
