Guest 5T33Z0 Posted June 25, 2022 Share Posted June 25, 2022 @Saranghero Does the HD 4600 even support HDMI2.0? If not, disable the "enable-hdmi20" key. Sometimes, the "device_type" key can cause issues as well. Disable it for testing as well. Quote Link to comment Share on other sites More sharing options...
Allan Posted June 25, 2022 Share Posted June 25, 2022 And correct me if I'm wrong, but the boot-arg shikigva=80 do not belong at device properties section, right? Quote Link to comment Share on other sites More sharing options...
Cyberdevs Posted June 25, 2022 Share Posted June 25, 2022 @Allan As far as I know boot-arg shikigva=80 as you said it yourself is a boot argument and it belongs under the nvram section not device properties but i'm not sure if that can be injected via device properties as well. 1 Quote Link to comment Share on other sites More sharing options...
Guest ricoc90 Posted June 25, 2022 Share Posted June 25, 2022 (edited) @Cyberdevs It can. However I believe the value of 80 is for enabling DRM on AMD dGPUs paired with an Intel iGPU, so I don't know if and what impact it has on an only intel iGPU system. If it even does anything at all since OP is on macOS 11+. See DRM Chart:https://github.com/acidanthera/WhateverGreen/blob/master/Manual/FAQ.Chart.md Anyway. none of this is answering OP's question Edited June 25, 2022 by ricoc90 Quote Link to comment Share on other sites More sharing options...
Cyberdevs Posted June 25, 2022 Share Posted June 25, 2022 @Saranghero AFIAK HD4600 works OOB under Big Sur you you don't need the DeviceProperties try without them and see if that resolves the issue. Quote Link to comment Share on other sites More sharing options...
Guest 5T33Z0 Posted June 25, 2022 Share Posted June 25, 2022 @Hervé device_type is not cosmetic only. In cases where no drivers are available it prohibits LVDS displays from turning on when running in VESA mode: https://github.com/5T33Z0/Lenovo-T530-Hackintosh-OpenCore/issues/14#issuecomment-924873892 Quote Link to comment Share on other sites More sharing options...
Marcobingo2 Posted September 10, 2022 Share Posted September 10, 2022 Hi, same issue here with an HP 400 G2 MT (i5-4590S - HD4600 - DisplayPort cable - 4K@60hz output). When my framebuffer-fbmem is set at 00000003 goes in 4K@60hz but Chrome and other software doesn't work, if I delete the framebuffer-fbmem goes in 1440p@60hz and the softwares works.
