Hi!
- They are the same. I'm not sure where I got the 0s from, if I remember right I got the version numbers directly from the BIOS itself.
- I'm not really sure to be honest. I have my Thunderbolt disabled via BIOS, since I don't use it for anything (and I don't have the dock either). Maybe @denzilferreira can help with this? I could be wrong but isn't only one of those USB-C ports Thunderbolt? Have you tested on Windows or Linux?
- I believe it's possible but again I don't have much experience with framebuffer patching I'm afraid. In Hackintool you can see in the "Connectors" tab, you could then set framebuffer-con-enable property to false for that connector in the generated patch, maybe that would do the trick?
I also recommend you take a look at WhateverGreen manual if you haven't already

Thank you for quick reply and sharing this info!

Why didn't I think of that? That explains a few things. Let me try disabling my thunderbolt too temporarily. That could solve many things including frame buffer patching.

I will also update on this approach too when I get my result.

Actually I read multiple times (although I am not that knowledgeable on this), but I guess reading once more might enlightened me. Thank you

Hey, this is one of the things I still haven't figured out either. Currently, I have mine setup like this:
This works with my thunderbolt 3 dock, with my screen connected over HDMI to the dock and USB-C attached the laptop. If I use the default setup of the repo, I don't get audio out on the USB-C. Since I rather have my laptop connected with just one cable, this works the best for me.

Hi, I think you might want to try this. It. basically enables 3 ports on motherboard, namely,
1-LVDS(BusID 0), 2. DP (TB Usb-C, BusID 5) 3. HDMI (BusID 2) on the laptop.
Above configuration will drop one of the usb-c port display near by lcd.
This gives me most freedom of connecting external displays.
I haven't check with TB3 Dock Gen 2 from Lenovo with this configuration yet. I will do that soon and let you know.

I tried this. Findings:
- HDMI port: audio and video works
- USB-C port (closest to display): video works, no audio
- USB-C port (farthest from display): no video, no audio (basically the laptop keeps trying to connect to a display on a loop)
Close but not there yet π

Hi, Denzilferreira,
Oh, let MacOS sleep and wake it up when you boot (just once). That's strange, but USB-C Port (farthest) works like a charm afterward! Side effect is HDMI port has to reconnected (which we already know).

thank you for checking out! Just out of curiosity, do you have a dGPU with t490? In that case, adding hda-gfx parameter may be important.
There must be some differences in VGAs in our Thinkpads (my T490s has an internal uhd620 only) or something else.
For sure, I cannot boot with the frame buffer configuration with current setting from repository. With above configuration I shared with you, I am able to boot without problem and get audios (btw, my monitor is 1080p).
I think I will stick to my personal configuration π
thanks,
UPDATE: I experimented my current configuration and here are some results.
- connect Samsung UHD monitor (without speaker?)
1.1) UHD Monitor <-HDMI-> HDMI 1.4 on board port connected: 2560x1440 max resolution. Monitor didn't have speaker so don't know :(
1.2) UHD Monitor <-HDMI-> Type-C DP-to-HDMI Adapter <-> TB Type-C port connected: 2560x1440 again.
1.3) UHD Monitor <-HDMI-> Thinkpad Mechanical Dock <-> TB Type-C port connected: 2560x1440 again
1.4) UHD Monitor <-DP-> Thinkpad Mechanical Dock <-> TB Type-C port connected: 2560x1440 again
1.5) UHD Monitor <-DP-> Thinkpad Thunderbolt 3 Gen 2 Dock <->. .... Not tested yet (To be updated)
....
From above, it looks like I had to use your extra prameters like:
dpcd-max-link-rate =<14000000>
enable-dpcd-max-link-rate-fix =<01000000>
I will try those and let you know if that work at all.
