ameris_cyning Posted May 26, 2020 Share Posted May 26, 2020 Have you tried injecting a fixed EDID? Link to comment https://www.insanelymac.com/forum/topic/343963-intel-hd4000-external-monitor-banding-gradients/#findComment-2723780 Share on other sites More sharing options...

I tried to enable HiDPI on my internal and external monitor via https://github.com/xzhih/one-key-hidpi Then I tried to add HiDPI to my 21:9 2560x1080 external monitor via SwitchResX 2 hours ago, Hervé said: Clover config seems erroneous with all those dropped SSDT tables (it's like you're dropping all the SSDT tables from BIOS) and all those injected ATI + nVidia properties. Honestly, I just used standard Clover settings and tried to start my external monitor. 2 hours ago, Hervé said: I've also noticed you're injected Capri layout 01660004 which is normally used for HiRes internal/built-in LCD. Yes, you're. Because only with this settings I can start my external monitor. Tried: 01660003, 01660008, 01660009, 01660002, 01660001. Maybe it's a wrong, but I didn't find another way. Internal monitor resolution is 1920x1080 2 hours ago, Hervé said: Then, you do not appear to have proper CPU power management in place so your system may be lagging and under performing. If you could help me, it will be great. If you could send manual for dummies how to configure it, it also will be great. 2 hours ago, Hervé said: what's the resolution of your built-in LCD? 1920x1080 IPS 2 hours ago, Hervé said: do you have a built-in discrete GPU (such as nVidia GeForce GT740M)? You're absolutely right! GeForce GT740m 2 hours ago, Hervé said: According to the specs posted here, your internal/built-in LCD should be LoRes @1366x768 No, I have FHD EWV LED version 2 hours ago, Hervé said: Why don't you post your entire zipped Clover folder? Attached to main post 2 hours ago, Hervé said: 24bit colour reported in SysReport->Graphics is what's expected. Thank you for clarification!

Thank you for your help and quick answer! I need to add, that external, but for it's not working correctly, right? In any case I need edit "AppleIntelFramebufferCapri.kext" From System/Library/Extensions"?

wegosi Posted May 26, 2020 Author Share Posted May 26, 2020 (edited) 1 hour ago, Hervé said: Just patch the kext using Clover's on-the-fly facility. Just... It's hard for me =)) Could you, please, tell, if can do it in Clover Configurator? If yes, is it a correct place as mentioned into the screenshot? And I need to fill only Find and Replace fields? Also I found AppleIntelFramebufferCapri.kext Should I open and edit Info.plist file? Info.plist seems not correct file I opened this And found 040066010103010100000002 and 0503000002000000300200000000000001000000400000000000000001000000400000000000000001000000400000000000000000000000 What I did in Clover Configuration with config.plist Is it correct? If yes, it's not working. Maybe I did it incorrectly.

wegosi Posted May 27, 2020 Author Share Posted May 27, 2020 Hello @Hervé I knot, that you're very busy. But your forum - is the one place, where somebody helps me.

wegosi Posted May 27, 2020 Author Share Posted May 27, 2020 (edited) 19 hours ago, Hervé said: You nearly got there... Yes, you use the Find/Replace field of Clover Configurator to apply the binary patch. What you did there was correct. What you got wrong was the Name field; it's the name of the kext/binary file that you enter there; instead, you've entered your own patch comment and that should go in the dedicated field that further away to the right (but not visible until you scroll). So, instead of videoPatch1 and videoPatch2, you must have AppleIntelFramebufferCapri. Thank you for your quick response! I renamed these patches. But there is not result. Maybe other settings should be changed? Thank you. config.plist Edited May 28, 2020 by wegosi Link to comment https://www.insanelymac.com/forum/topic/343963-intel-hd4000-external-monitor-banding-gradients/#findComment-2723944 Share on other sites More sharing options...
