M2 Mac Studio HDMI 2.1 Limitations - How does it compare to the M2 Pro Mac mini?

The M2 Max and Ultra Mac Studio finally comes with HDMI 2.1, bringing it up to par with the M2 Pro Mac mini and MacBook Pros. But does it have the same limitations the other computers do?
I've made several videos previously testing the limits of how well HDMI 2.1 worked on the 14" MacBook Pro and Mac mini with my 48" LG C1 TV that I use as a monitor. I was eager to see if any there were any improvements with the Mac Studio. After all, I didn't have an M2 Max chip to test before.

Great video. Would love to see you test games.

So at the end, can we set the Mac Studio M2 max to 4K 120 Hz or not please?

I use a LG c2 4k with macmini m2 pro and hdmi 2.1 I have 4k res 120hz with HDR enabled correctly Altough sometimes (completly casual) The screen turns off and on (rarely) But most of The time it keeps The correct resolution with hdr on

[@AlfonzoKnowsBest]

Yeah I have the same setup with the same issues. For the most part it's ok, but will flicker and turn HDR off. Just picked up the C2 on Prime day, thought the Tv was a lemon because I never had these issue with my 27" 4K HDR monitor... but that was only at 60 hrtz. I guess 4k HDR 120 hrtz wasn't a high priority at Apple.

macbook pro 2019 15" intel based mac and have 2K 144hz through usb c to DP cable, and second screen with FHD 60hz thought both are 34" 2K 144hz also this macbook is running insane hot above 60 to 90 sometimes 100 degrees

This is making me want to buy a PC instead.

HDR and Apple, buy Apple Display XDR, they will not allow HDR for free)

Awesome Video & Thanks :)

That hdmi port can output a native resolution (non scaled) 4k 120hz (or pro motion) with hdr enabled?

[@Aurummorituri]

Nope. It's not real HDMI 2.1 most likely like the consoles. HDMI 2.1 at it's full 48Gb/s bandwidth can output 4K 144Hz HDR. Xbox Series X is only 40Gb/s, and the PS5 is 36Gb/s since they use legacy display controllers. M2 chip likely was not built for HDMI 2.1 speeds, so they added the name and some features while the bandwidth seems not much better than regular Displayport.

Good info. My LG C2 started going black every 30 seconds or so and I think it may have been the HDMI cable. Switched to a 2.1 cable and no issues so far. I am curious. When I turn HDR on it seems my ability to adjust the brightness is disabled so I just get a hella bright screen. I'm using a Mac Studio with M2 Max and Sonora. Any help would be appreciated.
