HD4600, dual QHD monitors (DP+HDMI)?

[protech]

Hi guys,

I was wondering if someone could point me to the right direction regarding getting 2 monitors to use QHD resolution with mobile HD4600.

I'm trying to hook them up to my CyberpowerPC Fangbook Edge (HD4600) via DP and HDMI. In Windows, both monitors display full resolution, while in Yosemite, I can only get the monitor connected to DP to use full res. The other one, through HDMI, only up to 1080p.

I've read elsewhere that Mac OS X in general has trouble with higher resolutions via HDMI, but I wanted to check and see if you have any advice on how to make both monitors work.

Thanks a lot!

(BTW, Yosemite running with 965M disabled and everything set up nicely using RehabMan's guides )

Both monitors connected...

But probably a lost cause... seems most Macs don't have HDMI ports...

Hi - thanks a lot for replying!

IOReg attached.

You could try patching for HDMI-audio. Both of your ports are of type DP... but since one is actually HDMI, the other DP, I'd expect one of them to be marked HDMI...

There are patches for HDMI-audio in the config.plist files from my guide: http://www.tonymacx86.com/yosemite-...de-booting-os-x-installer-laptops-clover.html

You'll need to enable the correct one as appropriate.
