z1326 Posted October 4, 2017 Share Posted October 4, 2017 My laptop is AW M17X R4 , i7-3610QM, HD4000 + AMD 7970M(disabled). The HDMI output worked in 10.11 but failed after 10.13 High Sierra installed. Here are the DSDT,SSDT and config.plist patched.zip Here are the kext. Other.zip So could someone tell me what's the reason? UPDATE: The reason seems to be the SSD. I used an OEM version Intel 520 and I also tried Intel 525, the HDMI output didn't work. But it worked after I install the system into an Intel X25-M or a Sandisk SSD PLUS. Since the both Intel 520 and 525 is based on SandForce 2281 chip ( while Intel X25-M and Sandisk SSD PLUS is not ), is it possible that there're some compatibility problems for SandForce 2281 SSDs？ Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 4, 2017 Moderators Share Posted October 4, 2017 Do you mean HDMI audio or video? Post IOReg IORegistryExplorer_v2.1.zip with HDMI connected. Link to comment Share on other sites More sharing options...
z1326 Posted October 4, 2017 Author Share Posted October 4, 2017 Neither audio nor video works. And I can't see "Intel HDMI audio" in System Report --- Audio. Link to comment Share on other sites More sharing options...

Administrators Hervé Posted October 5, 2017 Administrators Share Posted October 5, 2017 No double post on the forum please... High Sierra's vanilla Capri FB shows the following layouts: 03006601 01020402 00000004 00000001 00000060 10070000 10070000 00000000 00000000 00000000 00000000 00000000 05030000 02000000 30000000 02050000 00040000 07040000 03040000 00040000 81000000 04060000 00040000 81000000 00000000 00020011 00000000 [...] 04006601 01030101 00000002 00000001 00000060 10070000 10070000 00000000 60B90400 00000000 00000000 00000000 05030000 02000000 30020000 00000000 01000000 40000000 00000000 01000000 40000000 00000000 01000000 40000000 00000000 00000000 00000000 i.e. the same as in El Capitan and Sierra for layout 01660003 and roughly the same for layout 01660004 (3rd line differs slightly).You're using the HiRes layout 01660004, so refer to the info I posted in post #32 of the Capri VGA/DP/DVI/HDMI guide. As explicitly stated in the post, that vanilla layout only supports LVDS output by default, so follow the guide. Link to comment Share on other sites More sharing options...
z1326 Posted October 8, 2017 Author Share Posted October 8, 2017 I think the config.plist and the dsdt should be OK cause the HDMI output works under some circumstances. I tried many times and found some strange results. HS system installed into SSD,APFS partition.--- NO HDMI output. HS system installed into SSD,HFS+ partition.--- NO HDMI output and the system partition will be transfered into APFS automatically. HS system installed into HDD,HFS+ partition.--- HDMI output works. I also get the HDMI output under APFS,SSD for one or two times but I don't know why I get that. Also, I found that even I get HDMI output under APFS,SSD. Once I enable trim though colver---Kext to patch. The HDMI output disappears. Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted October 8, 2017 Administrators Share Posted October 8, 2017 there are a few posts that indicate Trim on APFS is breaking HDMI and battery Link to comment Share on other sites More sharing options...
z1326 Posted October 9, 2017 Author Share Posted October 9, 2017 However for SSD even I disabled TRIM in clover patch I still can't get HDMI output back. Is there something I can do ? Or I have to wait Apple fix this ? Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted October 9, 2017 Administrators Share Posted October 9, 2017 did you rerun the cache rebuild scripts after changing trim? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 9, 2017 Administrators Share Posted October 9, 2017 SMBIOS profile can also affect HDMI output. Which profile did you configure? Link to comment Share on other sites More sharing options...
