pulleyluke Posted October 27, 2021 Share Posted October 27, 2021 Not sure if this is helpful at all, but i have the same issue on my laptop, i get around it by connecting to the displayport port on the docking station instead, seems to work great for my uses!

hiropa Posted October 27, 2021 Author Share Posted October 27, 2021 No luck here either. It only boots if I reset the frame buffer values to the ones below, which work fine for the screen in OC 0.6.9 but not in the later versions. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 27, 2021 Moderators Share Posted October 27, 2021 How many external display ports does it have? DP, VGA or HDMI Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 27, 2021 Administrators Share Posted October 27, 2021 If you inject a patch for con1/con2/con3 in a single injection at con1, I see no point re-entering another patch specifically for con3. Either inject everything in one go or all connector patches one by one. You add a 4th connector, i.e. a 4th video output port at con3. Why? Is this the connector used by that DP->HDMI output? Check this with the working OC 0.6.9 config and please be specific with what you do and your observations. I'd be more useful if you would post your entire iGPU properties injection (and without cutting parts out) rather than do it bits by bits...

hiropa Posted October 27, 2021 Author Share Posted October 27, 2021 This is the entire injection. It was taken from Angelts 0.6.9 EFI and not changed. It also has always been 4 ports. The physical ports on this Laptop are one VGA and one DP. But it also has a docking Port where I don‘t know how many ports are in there. Link to comment Share on other sites More sharing options...
hiropa Posted October 31, 2021 Author Share Posted October 31, 2021 As an update: I now copied the RTC fix and the additional Touchpad changes from 0.7.4 of angelts EFI and added them to the 0.6.9 version. Big Sur is now working fine with both screens and no CMOS reset issues. For some reason HDMI audio is not working and Monterey won't work because changing the model breaks the config.

angelts Posted November 1, 2021 Share Posted November 1, 2021 Would you try and share the results of this EFI.zip (generate new SMBIOS only) 1 Link to comment Share on other sites More sharing options...
hiropa Posted November 6, 2021 Author Share Posted November 6, 2021 Sadly got the same results with that EFI. But in the meantime I experimented a bit with the Config and had success with the following: Both displays are working, Hotplug is also fine, but HDMI Audio is still an issue. It shows up in the menu, but no sound is played. Link to comment Share on other sites More sharing options...
