Maybe in the future if it ever connects luckily, I will update it here.

It got connected properly to a original MacBook also through a type-c to HDMI dongle.

Both the laptop and the monitor go into some weird connectdisconnect loop, that.

When the monitor cycling reaches HDMI, for a few seconds both the displays work and then immediately back to cycling from the DP, DVI, HDMI.

My laptop also keeps weirdly switching in and out of multi-display mode.

The outcome is the same with and without each of the following changes.

And it is, which is correct only for HDMI type, from my understanding.

My Hardware details: External Monitor: Acer EB321HQU Laptop: HP 15-ay542tu Processor: i3 6006u (Skylake Mobile) Graphic Card: iGPU: (Intel Skylake GT2) Intel HD Graphics 520 (device-id0x1916) No discrete Graphic card.

Whatevergreen Version: 1.4.5-debug Lilu version: 1.5.0-debug Opencore version: 0.6.4-debug macOS version: 11.1 stable (20C69).

A copy with it working and one when it is not working, if possible.

Use the version of IOReg linked in this guide - Providing a copy of your EFI Folder would also be helpful.

You can redact the serial number, UUID, MLB and ROM entries in the copy of the config.plist.

So we can see what else you are using to boot your laptop.

Of the Framebuffer patches you could use with your Skylake IGPU (HD 520) the only one I know of with a HDMI connector is 0x193B0000, which would be entered against the AAPL,ig-platform-id as, not sure you would need the con0, con1 or con2 entries with this framebuffer.

What other graphics fixes, SSDTs or kexts have you added to your system WhateverGreen.kext is a given and should be retained with Lilu.kext.

Have you remembered to remove the fixes, SSDTs and other kexts after finding out they didnt work.

View attachment 512848 All the other mobile framebuffers for the Skylake series of IGPUs have the obligatory LVDS and two or three DP connectors.

Which is the same as patching connection type for con1 with my own platform-id (I suspect even this is not required coz ioreg says con1 is of type HDMI only).

Even then 193B patched bus-id also gave the same outcome, connectdisconnect loop.
