Mac mini: 4k @ 120hz?

[Abbas]

I do have access to a Logitech 2.4GHz receiver so let me try using that with the Mac and report back.

Damn! I can confirm using a USB receiver works! I connected the G502X to the Mac with the supplied Dongle, and the difference is VERY visible. Still not as smooth as Windows but I can work on this now without getting irritated.

 

[Technotron]

Nice, good to hear. I've ordered a second hand magic trackpad, will also report back... 🙂

It can do 4k@120hz 4:2:2
Alan Spiegel does get with this Adapter RGB 4k@120hz, dont know how they can reach this. This Adapter has an VIA Billboard:

FYI I bought exactly this adapter and mine was VMM6100 🙁

Has anyone was able to make this hack working on Mac m1 + Sony A90j (which supports VRR).
I am asking because I tried changing EEID, updating firmware for Cable matters cable https://www.amazon.de/dp/B08QDV5H4M?psc=1&ref=ppx_yo2ov_dt_b_product_details&tag=macr05-21.

Same thing here. I ordered two more adapters (different ones) to play some more lottery on that...

I also haven’t had any luck with that one. Seems like it’s a no go, same with the Sabrent USB type c to HDMI 2.1

The Cable Matters usb type c to hdmi 2.1 adapter (VMM6100) will work at 422 with EDID changes.

But we have to talk about Bandwidth and Specifications.

Iam not a Pro so if @stevemr123 and @joev can Assist it will be perfect!

DP has a limitation of HBR3 width 32,4 Gbit/s with 4 Lanes, so it can do 4x8Gbps.

DisplayPort – Wikipedia

de.m.wikipedia.org

How DisplayPort Alt Mode is Enabled over a USB Type-C Cable

A USB Type-C cable connection can act as a USB host, USB device & as a DisplayPort video connection.

evision-webshop.de

Mac does not support DSC i think ?? So we need uncompressed Bandwidth to check. In my Case Mac does never use DSC with an USB-C/TB4 or USB4 Adapter/Station!

DP-ALT without DSC will be Limited to 4k@120hz 4:4:4 8-bit. 10-bit is not possible!

Theres also another things we have to know. Mac M1 can not use USB-C 3.2, they are Limited to 5-10Gbps.

Mac Studio (2022) - Technical Specifications – Apple Support (UK)

support.apple.com

Tests show Thunderbolt ports on M1 Macs don't fully support USB 3.1 Gen 2 speeds

New test results from Howard Oakley of The Eclectic Light Company show that the Thunderbolt ports on M1 Macs don't take full advantage of the promised speeds of USB 3.1 Gen 2 devices.

www.dpreview.com

This is how to get better USB-C speeds on M1 Mac (all models)

A new report published claims that M1 Macs don't truly support USB 3.1 Gen 2 and thus don't offer Thunderbolt 4 speeds. But there's a way you can get increased speed on M1 Macs. Here's how!

pocketnow.com

M1 Mac Thunderbolt 4 ports mostly don't support 10Gb/s speed - 9to5Mac

Pro users of M1 Macs have reported disappointing transfer speeds with external SSDs, and tests appear to show that most M1 Mac Thunderbolt 4.

9to5mac.com

Fallback to 5Gbps on all M1 Macs expect from Mac Studio front connections:

Apple: Thunderbolt in M1-Macs unterstützt wohl keine 10 GBit/s - Golem.de

Thunderbolt-Ports sollten auch USB 3.2 Gen2 mit 10 GBit/s unterstützen. Laut einem Test ist das wohl bei M1-Macs nicht immer der Fall.

www.golem.de

I did read Mac Studios have different types of connections. the Front ones can do USB 3.2 with 10-20Gbps, so this will be enough for full DP Bandwidth.

I dont know if this also will be a Problem. When the Chips only get 5-10 Gbps on 2 Lines( 2,5-5Gbps per Line) so DP Alt is maxed out 10-20Gbps ?? Is this limitation the reason why we only get 4:2:0 or sometimes 4:2:2 !?

I dont understand why the Anker works with 4:4:4 4k 120hz 8-bit, but this is the best whe can get with DP-ALT without DSC ! So the Anker does it right with Cable Matters Custom Firmware for VMM7100 Chips (https://forums.macrumors.com/threads/mac-mini-4k-120hz.2267035/post-31968090)

Can someone with Mac Studio M1 MAX and M1 Ultra test if it works better when u connect the Adapter on the 2 Front USB-C Connectors ?

The Mac Studio with the M1 Ultra has two TB4 ports on the front instead of two USB 3.2 ports. So, you get the full 40 Gbps bandwidth from the front ports on the Studio w. M1 Ultra.

Yeah but I dont think this Adapters utilize TB4 DP-ALT they will let Apple Hardware think its an USB-C Device and then it will be limited to around 10-20 Gbps !

You're the Man, AironMan. Ordered the Anker from Amazon here for $50.
Applied your firmware file using my Lenovo Legion 7 laptop=PROFIT
No need for EDID or 3rd party apps, I've got 4:4:4 4K120. I did have to switch to 60/120 twice to get it to work at 444 though. Not sure why, but mad props to you.

 

[Technotron]

So in the long run, I am considering the solution with the Anker dongle + itec dock, as I would also prefer a one-cable-does-all solution, but I am not about to spend another 250 EUR just yet (lol).

I am wondering if I can update the FW of my cable (https://www.amazon.nl/dp/B09MCXCWTQ?psc=1&ref=ppx_yo2ov_dt_b_product_details) to get the full RGB range out of it.

1. AironMan, where exactly can I see the chip used in my cable?
2. Could you hook me up with the exact flashing procedure once more?

Edit: weird, I don't see any info regarding my USB C - HDMI adapter... perhaps because I am already running a modified EDID?
