Hi RehabMan,
I know dGPU and external display is probably not on your priority list (probably because there's more urgent things to get working first) but I thought this might be interesting for people looking for high end laptops with great features and connectivity:
I'm using a HP ZBook 17 with Intel HD 4600 graphics and recently added a AMD FirePro M6100. Surprisingly, the card works OOB with Clover and El Capitan --with a few caveats that is. I'm testing it with dual monitor setup (internal + DP):
Hybrid Graphics disabled (AMD only):
-wake from sleep doesn't work (seems to be a known issue in El Capitan with AMD cards)
-internal display shows some color artifacts (like bad JPG) even though QE/CI is working. External DP monitor seems fine
-laptop just turns off when GPU is under heavy load. Tested with StarCraft2 and laptop will simply shut down(!) after a few seconds of the game running
Hybrid Graphics enabled (Intel HD + AMD):
-internal display works fine (no color artifacts) but external DP monitor is flickering heavily as soon as the mouse is moved.
Do you have any pointers for what could be causing these problems? I'm especially surprised about the color artifacts (hybrid off) and by the external display flickering (hybrid on).
I'm attaching both IORegs as reference.
Thanks!
