ss2sameer Posted December 6, 2016 Share Posted December 6, 2016 my intel hd 530 seems to be working fine, but boots to black screen. its shows all ok parameters if checked via screen share. 1536MB memory and reports intel SKL graphics. if inject intel=true in clover will boot with 31mb graphics but internal laptop screen shows up. do i need to edit port config? how do i determine and define it. thanks Update: See some update here Quote Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted December 6, 2016 Administrators Share Posted December 6, 2016 can you shine a light into it and see if there is an image? maybe the backlight is off. Quote Link to comment Share on other sites More sharing options...
ss2sameer Posted December 6, 2016 Author Share Posted December 6, 2016 The backlight is working. its even controllable by fn +f11 and f12. but no image. the screen resolution as shown in screen share is less and is clear from there no display is detected. thanks Quote Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted December 6, 2016 Moderators Share Posted December 6, 2016 did you set the DVMT to the required 96MB? when you enable inject Intel, did you set the ig-platform-id to 0x191b0000? Do you have nv_disable=1 to disable the nvidia card, set BIOS to enable switchable graphics? Quote Link to comment Share on other sites More sharing options...
ss2sameer Posted December 7, 2016 Author Share Posted December 7, 2016 Hi yes my DVMT has been set to 96MB. when I enable inject Intel, I do set the ig-platform-id to 0x191b0000? Yes i have tried nv_disable=1 and enable switchable graphics in BIOS (it gets disabled after every reboot, a separate issue) thanks Quote Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted December 7, 2016 Moderators Share Posted December 7, 2016 What SMBIOS are you using? whatever it is, try replacing the board-id with this Mac-27ADBB7B4CEE8E61 Quote Link to comment Share on other sites More sharing options...
ss2sameer Posted December 7, 2016 Author Share Posted December 7, 2016 I am using 17,1 have tried 14,2 with no success (with AGDP fix) tried changing the smbios with the given board id, didn't help which is the right direction with injectintel true or false?
