I have a monitor that support 4K/120HZ with an HDMI 2.1 input. If I get an adapter to connect to the TB4, will that get me to 4K/120Hz? The technical spec isn't clear as to whether that would work.
I have a Gigabyte M32U which supports 4K up to 144 Hz. I just tested it and that worked on my Mac but I put it back to 120Hz as I really can't tell the difference between 144Hz and 120Hz but 120Hz to 60Hz is very noticeable to someone like me who reads content as they scroll. It makes for a much better experience.
I connect by using a CablesMatter Usb-C to DP 1.4 adapter to connect to the DP 1.4 port in the monitor. I didn't try converting the USC-C to HDMI 2.1
Hdmi 2.1 supports 48Gbit/s. 4k@120Hz with 10bit is only around 36Gbit/s. No matter what the reason is all the new OLED tvs and similar use hdmi 2.1 and Apple is causing an unnecessary issue for their users.
In my opinion, Apple has already made its priorities quite clear.
The newest MacBook Pro M1 models offer an HDMI port, limited to HDMI 2.0, good for 4K at 60Hz, maximum.
The rest of the ports readily support variants of DisplayPort, such as DisplayPort-over-Thunderbolt, which can be run at higher resolutions and higher refresh rates.
If you want to use Macs, that is what is currently on offer. If that is not what you want, walk on by.
Hello MannyNYC,
We see that you need help connecting an external display to your Mac.

Cheers!
That's not correct, HDMI 2.1 has much higher bandwidth compared to DP 1.4, while both support 4k 120hz and 8k 60hz.
The Mac standard is that it must work with no data under-runs and no dropouts or partial blank lines at all under any circumstances. "Works without hardly any dropouts" is not good enough.
Windows leaves whether it actually works without data loss as an exercise for the User. Windows does not enforce ANY standards.
Grant, the cables are designed for the bandwidth and they already work in Windows. Apple should commit to this as it's important for its customers and will only become more so. I'm extremely disappointed that for years I cannot even get 4k 444 HDR even at 60hz out of an Apple via HDMI :( I ended up having to get a PC
There is nothing on that page about 4k/120Hz support - you sent me a link to how to connect a display, not what that connection supports in terms of resolution/refresh rate
This still doesn’t answer the question of whether the device supports 4K 120Hz through Thunderbolt 4 port. We already know that the HDMI 2.0 only supports 4K 60Hz, but that not what the question is.
That is great news!
Maybe Apple should change their specs to reflect that. You could suggest that here:
.
converting to HDMI is a step backward. HDMI has far less bandwidth overall.
Hey MannyNYC, how did you get this to work? I have a macbook pro 2019 with a M32U as well but it only gives the option of 60hz when using usb-c to usb-c with thunderbolt4
Hey Manny!
Are you confirming you get 4k at 120hz from your macbook with thunderbolt? :)
This is unfortunately very true regarding Apple's priorities. Apple not caring about its computers outputting properly to modern TVs for 3+ years is an embarrassing set of priorities in my opinion.
Your requirements sound like a job for an external GPU chassis.
You really don't think Apple should prioritize outputting even 60hz HDR 444 4k to modern TVs? Why are you calling requirements like that "my requirements" ;P
Can you get a 4K / 120Hz support from a Thunderbolt 4 port on 2021 MacBook Pro?
