Administrators Hervé Posted Monday at 06:47 PM Administrators Share Posted Monday at 06:47 PM The graphics properties you inject look overly complicated to me; I'd be surprised if you need more than a third of them. You've opted for CFL framebuffer 0x3E9B0000: ID: 3E9B0000, STOLEN: 57 MB, FBMEM: 0 bytes, VRAM: 1536 MB, Flags: 0x0000130B TOTAL STOLEN: 58 MB, TOTAL CURSOR: 1 MB (1572864 bytes), MAX STOLEN: 172 MB, MAX OVERALL: 173 MB (181940224 bytes) Model name: Intel HD Graphics CFL CRB Camellia: CamelliaDisabled (0), Freq: 0 Hz, FreqMax: 0 Hz Mobile: 1, PipeCount: 3, PortCount: 3, FBMemoryCount: 3 [0] busId: 0x00, pipe: 8, type: 0x00000002, flags: 0x00000098 - ConnectorLVDS [1] busId: 0x05, pipe: 9, type: 0x00000400, flags: 0x00000187 - ConnectorDP [2] busId: 0x04, pipe: 10, type: 0x00000400, flags: 0x00000187 - ConnectorDP 00000800 02000000 98000000 01050900 00040000 87010000 02040A00 00040000 87010000 It's not the recommended framebuffer for laptops, the default (recommended?) one in the WEG user manual being 0x3EA50009: ID: 3EA50009, STOLEN: 57 MB, FBMEM: 0 bytes, VRAM: 1536 MB, Flags: 0x00830B0A TOTAL STOLEN: 58 MB, TOTAL CURSOR: 1 MB (1572864 bytes), MAX STOLEN: 172 MB, MAX OVERALL: 173 MB (181940224 bytes) Model name: Intel HD Graphics CFL CRB Camellia: CamelliaV3 (3), Freq: 0 Hz, FreqMax: 0 Hz Mobile: 1, PipeCount: 3, PortCount: 3, FBMemoryCount: 3 [0] busId: 0x00, pipe: 8, type: 0x00000002, flags: 0x00000098 - ConnectorLVDS [1] busId: 0x05, pipe: 9, type: 0x00000400, flags: 0x000001C7 - ConnectorDP [2] busId: 0x04, pipe: 10, type: 0x00000400, flags: 0x000001C7 - ConnectorDP 00000800 02000000 98000000 01050900 00040000 C7010000 02040A00 00040000 C7010000 Maybe you can explain why: you opted for framebuffer 3E9B0000 you patch con1 in such a way you patch con2 in such a way you inject con3 properties in a framebuffer that has no such connector (and in which you do not even add this connector hence nothing in IOReg!) Personally, I'd have just changed connector con1 type to HDMI: framebuffer-con1-enable framebuffer-con1-type 00080000 so I recommend you start by removing all the non-sense you currently have for con1, con2 and con3. Note that injecting properties that bear the save values as the native ones is completely useless; though it does no harm of course, other than complicate a lot more your configuration. You also need to remove boot arg -igfxsklaskbl from your NVRAM settings; that's completely inadequate. It's for Skylake laptops and for an older version of macOS under very specific conditions. A total non-sense on your 10th gen (CML?) platform with UHD620 iGPU. It would be useful if you could specify the exact model of i7 CPU fitted in your ThinkPad x390. And if you have doubt about the connector linked to the HDMI output, please take an IOReg when your HDMI screen is connected to your laptop.

pawan2joy Posted Tuesday at 07:02 AM Author Share Posted Tuesday at 07:02 AM Processor is : Intel(R) Core(TM) i7-10510U CPU @ 1.80GHz 2.30 GHz I changed the devide ID and removed con1..con3... Also attached is the IOReg file after inserting the HDMI cable. MacBook Pro.zip config.plist.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted Wednesday at 07:09 AM Administrators Share Posted Wednesday at 07:09 AM Again, I recommend you remove all that crap you've got for the connectors and stick to the 2 lines I posted above. At this stage, your HDMI screen does not even appear in IOReg which can't be a surprise. For the rest, it would appear you followed the Dortania recommendations, at least as far as the OC configs concerned. Link to comment Share on other sites More sharing options...
pawan2joy Posted Wednesday at 11:58 AM Author Share Posted Wednesday at 11:58 AM made the changes as suggested, tried different platform IDs but then it gets KP. so HDMI output is still at same level... but i will keep on looking and testing, lets see.. after doing this my video is not coming in zoom/teams call.. config.plist.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted Wednesday at 12:16 PM Administrators Share Posted Wednesday at 12:16 PM Then you may want to retry without the fbmem/stolenmem injections. You never know, your laptop may be set with 64MB or more of DVMT. Do that with a USB key as you don't want to break your Hack. Link to comment Share on other sites More sharing options...
pawan2joy Posted Wednesday at 12:39 PM Author Share Posted Wednesday at 12:39 PM got KP... so back to same config Link to comment Share on other sites More sharing options...
Administrators Hervé Posted Wednesday at 03:29 PM Administrators Share Posted Wednesday at 03:29 PM IOReg with HDMI plugged in please. I take it you do reset NVRAM when you reboot after changing your config, right? Link to comment Share on other sites More sharing options...
