Sapphire HD 7870 OC (1050Mhz) - multi display support

[Sunman]

Hi
Finally native support for AMD 7xxx but is there any way to have more than single output enabled for 7870 (device ID 0x6818 - vendor 0x1002). If I connect more that two monitors in any to the output (have 1x hdmi, 1x dp, 2 DVI) the 10.9 just blocks... Installed the Multi beast with DSDT (downloaded from here for my MB Z68XP-UD5 with i7-2600 (HD2000)), GE=no

See the attached image for details


Everything works but I just got crazy about this "missing" multi monitor support.

Also is is possible some one to post its LuxMark results for HD 7870 (I got 1030 points but it looks low for this device - in windows I get 1400 points)

Also is it supposed to have AMDRadeonAccelerator.kext when using 10.9 - I don't have such kext into S/L/E?
Thanks...

It seems Apple destroyed multi-monitor setups in 10.9.3 update, there is no way to get them working unless you install 10.9.2 or older Mavericks. This problem is driving me crazy aswell, im using 7870 Eyefinity 6 card, and only 2 screens are working (rest 4 are just black but are getting signal tho, they are also visible in screen configuration, but no picture :/). I have also tried 10.9.4 beta 1, but the problem still aint fixed. Pretty awesome job from Apple.
