@pokenguyen - thanks - I did search but find a lot of {censored}. I should have looked at your page  - you are one of my trusted advisors!

 

i very much appreciate the response. As you know i am an expert on HD 3000 (T420...)  but just coming up to speed on HD 4000. trying to get this Lenovo G780 set up for my daughther.

 

the new system works pretty well with just clover dsdt patching. just need to figure out why it won't sleep when i close the lid!

thanks.

well yes i am using clover.it just got ahold of this g780 and got it working mostly. it is getting the EDID injected properly.

 i have done a bit more research on this. 

i could be wrong that ig_platform_id =3 will not support 1600x900 resolution. however,  ig-platform-id =4 works at this resolutoin. but i don't have HMDI with id=4. so one step at time. there must be a way to edit the buffers to add ports? not sure

@iceprogrammer - i am seeing the same thing pretty much on my new Lenovo G780 - only seems to display stuff with ig platform id 3 or 4. with 3 i half screen and HMDI works. with 4 i get correct LVDS but no HDMI. what did you figure out?

 

i am using MBP9,2 platform
