Asus x301a everything is working apart extended monitor.

[chriz74]

The only problem is that I don't get extended display if I boot with the external hdmi display plugged, the internal one lights up but no picture is displayed. Any clue?
If I hotplug the hdmi display when already booted I got extended correctly, also if I close the lid the external becomes primary and if I reopen the internal turns on again correctly.
So how comes this doesn't work if booting with the hdmi display already plugged in?

 

My system specs suggest hd4000 id 1660009 so I put that in the dsdt instead of 1660003

Then applied these patches:

for lvds internal video to work

AppleIntelFramebufferCapri 010000000200000030000000 to 050300000200000030000000

for hdmi and dvi

DVI (probably not needed as I only have an hdmi port)

AppleIntelFramebufferCapri 020500000004000007010000 to 020500000008000006000000

HDMI (audio works)

Hi,

 

On my HD4000 i applied this one on 01660004. For the external devices the DVI and HDMI from 01660003 have been used.

 

Before: 

04 00 66 01 01 03 01 01 00 00 00 02 
00 00 00 01 00 00 00 40 10 07 00 00 
10 07 00 00 00 00 00 00 20 50 03 00 
00 00 00 00 00 00 00 00 00 00 00 00 
05 03 00 00 02 00 00 00 30 02 00 00 
00 00 00 00 01 00 00 00 40 00 00 00 
00 00 00 00 01 00 00 00 40 00 00 00 
00 00 00 00 01 00 00 00 40 00 00 00 

After: 

04 00 66 01 01 02 04 02 00 00 00 04 
00 00 00 01 00 00 00 20 10 07 00 00 
10 07 00 00 00 00 00 00 00 00 00 00 
00 00 00 00 00 00 00 00 00 00 00 00 
05 03 00 00 02 00 00 00 30 02 00 00 
02 05 00 00 00 08 00 00 07 04 00 00
03 04 00 00 00 08 00 00 81 00 00 00 
04 06 00 00 00 08 00 00 81 00 00 00 

Perhaps this also works with the 01660009
