Removed - restart loop still exists.

What happens with HDMI as the boot display?

What happens with HDMI as the boot display?

Only HDMI - boots OK
Only DVI - boots OK
DVI & HDMI - restart loop

In BIOS there are very little settings to choose (init first, vram, multi display). Tried every combination without success.

I've noticed that if i plug second monitor (no matter which is the 1st and which is 2nd) after clover appears (even in clover bootlist) then the system boots OK with 2 monitors plugged in.

Edit:
Booted in verbose mode and got unknown cpu warning - after that (3s?) computer reboots. Maybe it'll be helpfull...

Consider a DP2DVI adapter. No other ideas.
CPU power management is not enabled, no effect on graphics.

Thank you for your opinion. I will order one and see what happens...

I've received the DP 2 HDMi converter and still nothing... Patched DP2->0x7 in config.plist and the only difference is that Intel driver crashed while trying to hot plug the DP adapter into the computer... both monitors fade out, and few seconds later computer restarts by itself (jest the same while booting!). Just noticed that glitches in loading apple logo shown just before logon window dissappeared.

I'm really confused and in a good way to give up...

Two questions:
- should clover be installed in uefi or legacy mode? (or it doesn't metter?)
- what's for config.plist placed in EFI/EFI/CLOVER/OEM/SystemProductName ?

No surprise, wrong adapter.

Skylake / HD530 graphics:

The new 10.11.4 intel graphics works for me. When inject intel = false and all other 'intel graphics' related kext patches removed (except for HDA / audio ones).

* But it only works for me on HDMI port.
* D-SUB output goes blank (off) at time the driver is loaded.

2 Questions:

* Does this intel graphics also work over DVI ?
* Does this intel graphics work for 2+ screens ?

I ask because:

* My motherboard has 3 ouptuts, D-SUB, DVI-D, and HDMI
http://www.gigabyte.com/products/product-page.aspx?pid=5497#sp

* My main monitor is D-SUB only. So the only way to get it to work would be by buying an active DVI-D --> D-SUB adapter.

But if DVI output doesnt work for this Intel HD530 Graphics on 10.11.4 update, then theres no point buying such DVI --> DSUB adapter in the first place.

DSUB will not work, ever.
HDMI is not reliable, yet.
DP is best choice, NA in your case.
DVI is unknown.
2 screens, not yet.

I've connected DP2DVI with second monitor with patched 0x7 port and still got restart loop. While trying to hot plug the DP then drivers brakes and system restarts immediately (I can hot plug monitor via HDMI though and it works fine). Any ideas... ? Or the only solution in my case is external GPU...?
