Pluskat5000Schiffe Posted April 8, 2020 Share Posted April 8, 2020 Then it looks that this is the issue. With 2.77 you have 32MB DVMT which is enough for 1080p. For 1440p you need probably more DVMT... Does somebody knows to fake macOS that a 1080p monitor is attached instead of a 1440p? Link to comment Share on other sites More sharing options...
Donw35 Posted April 8, 2020 Author Share Posted April 8, 2020 (edited) So I did some quick testing, I connected my machine to a 4k Monitor and was able to get 2560X1440x60hz in OS X and 4k in Windows 10. Be sure you are using a quality DP cable, cheap ones or adapters can cause issues with OS X including crashing. Actually I was able to get 4k and bump the ram to 2gb. I think you have either a bad cable or bad RAM Edited April 8, 2020 by Donw35 Link to comment Share on other sites More sharing options...
Pluskat5000Schiffe Posted April 8, 2020 Share Posted April 8, 2020 SO let wrap up. You have bios 2.77, You have Catalina 10.5.3 or 10.5.4, TY very much I will try to swap a few things. Link to comment Share on other sites More sharing options...
Donw35 Posted April 8, 2020 Author Share Posted April 8, 2020 I am running 10.15.4 Catalina, 2.77 BIOS, tried this on SFF, USFF. Display port to Display port, no adapters. 16Gb Ram. 4k works solid in Win10, works in OS X but patches in clover needed, even then not as solid, I don't use it. Might I suggest install win10 and running the machine through some tests, it shouldn't be this hard to get that machine to work. Link to comment Share on other sites More sharing options...
Pluskat5000Schiffe Posted April 8, 2020 Share Posted April 8, 2020 (edited) In windows it works totally fine. I see idd also 2GB memory usage at GPU. Special Bios settings needed? I just default them and disabled legal booting. Or does it require specific other things? I changed DP cable no results.

Donw35 Posted April 8, 2020 Author Share Posted April 8, 2020 Nope, default settings. I know its frustrating man.. have you swapped the memory in the slots ? Link to comment Share on other sites More sharing options...
Pluskat5000Schiffe Posted April 8, 2020 Share Posted April 8, 2020 Yes I'm now with only one stick. Maybe I should reflash 2.77 This I EFI I currently use with clover 5108 CLOVER-8.zip which is yours. Can you double check all is in? I had it working in Mojave. Maybe I give it a try again with Mojave. Did you upgrade from Mojave to Catalina or clean install? Link to comment Share on other sites More sharing options...
Donw35 Posted April 8, 2020 Author Share Posted April 8, 2020 (edited) ok, let's do this, remove USBPorts.kext and replace it with USBInjectAll.kext, then in clover in the Kernel and Kext Patches enable the two items for USB port assignments. Let's make sure that the USBPort.kext I created for my machine isn't causing issues for yours. I am assuming you never placed any kexts in /Library/Extension correct ? that's a no no... I did upgrade on one machine and fresh install on another. no issues with either Edited April 8, 2020 by Donw35 Link to comment Share on other sites More sharing options...
Pluskat5000Schiffe Posted April 8, 2020 Share Posted April 8, 2020 Thx for this suggestion. It did not help. Now I will try Mojave... Link to comment Share on other sites More sharing options...
Pluskat5000Schiffe Posted April 8, 2020 Share Posted April 8, 2020 didn't make a difference. When I disable WEG I get GUI but 7MB Vram. I will try now older LILU / WEG combination. Link to comment Share on other sites More sharing options...
Pluskat5000Schiffe Posted April 8, 2020 Share Posted April 8, 2020 (edited) I have interesting information .... Revert back latest LILU +WEG and I had to do this: Add PciRoot entry for iGP, platform was ig-platform-id=0x0d220003 byte swapped 0300220d and device ID was device-id 12040000 byte swapped 00000412 Now I have install GUI installing Catalina right now. Installed and Gui is working... I do however only have 14MB VRAM config kopie.plist Edited April 8, 2020 by Pluskat5000Schiffe Link to comment Share on other sites More sharing options...

Pluskat5000Schiffe Posted April 9, 2020 Share Posted April 9, 2020 I tried it. With these settings it won't load the 2nd apple graphic or 2nd boot phase.

Pluskat5000Schiffe Posted April 9, 2020 Share Posted April 9, 2020 I give up ... downloading all bios-es from HP FTP and will reprogram as soon my BIOS programmer arrives.

riptest Posted May 28, 2020 Share Posted May 28, 2020 Hi, Donw35. Would you like to share 10.5.5 EFI config for us? old version not working on 10.5.5. thanks. Link to comment Share on other sites More sharing options...
Donw35 Posted May 28, 2020 Author Share Posted May 28, 2020 Here is the OpenCore 5.8.0 EFI I am using on the HP 800 G1, your mileage will very. you should be able to boot to the desktop and then create your own serial numbers in the PlatForm section. not doing so will result in iCloud and iMessage not working. Give it a try and report back. HP_800_G1_OC_58.zip 1 Link to comment Share on other sites More sharing options...
