Quick question before I flash: I got the 201388-A version of the cable matters adapter, and VmmHIDTool says "Firmware version: 7.02.120", which seems newer than the 7.02.112 version from OP. should I flash the 112 one anyway?
Got a tip for us?

Read the OP there are some Dock where are confirmed:
I use this one:
i-tec Thunderbolt 4 Dockingstation mit Stromversorgung 96W - 2X TB 4, 1x HDMI, 1x 2.5GLAN, 4X USB 3.1 Gen2, 1x SD, 1x Audio/Mik
I-TEC Thunderbolt 4 Dual Ekranas Docking Station PD 96W IT version

Yes, the Firmwareversion Number is not nessasary, its the configuration in this special Firmware where is important.
Sorry I came across this thread and want to make sure what I need to do is possible before I go down the rabbit hole.
I have a 16" M2 Max Macbook Pro with a 42" LG C2. It does 4k/120hz with HDR. Every time I disconnect the HDMI the PC icon changes on the LG OLED to regular HDMI and I have to redo the PC icon to get correct settings. If I get one of these adapters, will the PC connection stay? Also allowing me to do the full 4k/120hz with HDR? Or am I losing anything?

HDMI PC switch is an LG thing, put a request to LG. This is also present on CX C1 C2 and so on.
So this won't fix that problem correct? No point for me to do this if the HDMI output on my M2 Max is alread giving 4k/120 HDR/VRR.
Yes. U can use a native Dock where are always connected to the Dongle and are always on to prevent this issue. There are some things that u can force on EDID override like RGB. But i never seen that LG TVs automatically switch to PC Mode, anyone else here ??
Can you explain this a bit better. So if I get the dongle, it won't fix my issue for PC Mode switching. BUT if I get a dock, it will? Since the HDMI will be locked in the dock? Wouldn't the same be said for the dongle?
Wanna buy dell wd22-tb4 dock, will it give 4k@120hz 4:4:4 hdr with vmm7100 cable or hdmi or display port?

Everything is clear. However, I have a question, do I need to buy both of these adapters?
Sorry if it is already answered, I didn't go through all of the pages.
Of course. Just that it's an expensive option already, hard to find on top of that, and I would have no use for my existing dock then.
Thank you.
What about using Picture-by-Picture (PbP) mode to combine two adapters and two cables to acheive 7680x2160?
My monitor supports PbP and 7680x2160 @ 240Hz. Can I patch the firmware of two Cable Matters 201388-A adapters to acheive this resolution smoothly?
I have a maxed out MacBook Pro 16" 2019 (Intel i9, not Apple Silicon), and a Samsung G95NC monitor.
I have flashed the 201388-A = VMM7100 Cable Matters adapter as indicated. For me the firware attached in the zip files on the first page of this thread, after flashing, did not work at all when trying to connect my windows laptop to my LG C2 and they did not work when trying to my MacBook Pro M1 16 to my LG C2. I have managed to flash the firmware files provided by Alec Sullivan in this youtube video ->
in his comments: https://l.linklyhq.com/l/1qSry. Flashing them on my 201388-A = VMM7100 Cable Matters adapter made the adapter work for both the Windows laptop and for the Macbook at 120 RBG 10b 4L10 on my LG C2.
However I am very very curios on the following aspect: I have noticed that the adapter gets a bit warm. I have not taken a direct temperature measurement but I will. It is my impression that the MacBooks battery is draining faster or at least A LITTLE FASTER than usual. To me, the fact that it is running at 120 FPS and getting warm indicates that there is a noteworthy amount of power going through, being drained from the battery.
Is there anyone here on the forum with similar experience of this particular adapter getting noticeably warm? Does anyone with a different adapter have the same issue?
Does anyone know of any way I might be able to monitor the power output going through the ThunderBolt port where the dongle is connected? I am very very curious to see what sort of impact this has on the power consumption... especially compared to the power consumption that would be expected via the normal HDMI output. Any thought?

On M1 Ultra, I am able to get 1440p or above with HDR at 120Hz, but I can't seem to get the same with the M2 Ultra. The HDR toggle disappears when at or above 1440p at 120Hz. HDR shows if I set it at 100Hz or if I go to 4K 120Hz. So weird, is anyone experiencing this?
Specs:
Mac Studio M2 Ultra
LG C2 42 OLED
8K UHD cable
Cable Matters VMM7100
Ventura 13.5
Mac Studio M1 Ultra works perfectly fine.

Btw I don't get HDR at 120 hz. I have to turn it down to 60 hz to get HDR. It's not really a problem though as most movies are 24fps.
I mean it makes sense too, display stream compression will only take you so far.
In my experience, keeping the adapter connected DOES fix this issue of the TV switching off of PC mode, no dock used here. However, you'll have a new issue of your machine not wanting to wake from sleep sometimes (have to disconnect and reconnect the adapter to the Mac). Doesn't happen very often, and I'd say it's less annoying than fumbling with the LG menus to get back to PC mode.
I'm not using HDR though so can't comment on that.
Is there anyone whose external display gets disconnected when closing the lid?
I can get my USB-C hub working for 4K 120hz 10bit external output but it disappears when i close the lid

What laptop? For my Macbook M2 I'm using this software that prevents the laptop from going to sleep when I close the lid and the laptop is not connected to the power. Otherwise the external display gets disconnected when I close the lid because the laptop is going to sleep.
