Which cable are you using? Is it an active one?
Did you check in Windows that it is actually 4K@60 RGB and not just YCbCr?
Club 3D is one of the recommended brands for this scenario.

Hi there.
I thought that the HDMI port of Mac Pro 2013 was 1.4 and would only display 4k @ 30Hz maximum whereas the TB ports would do 4k @ 60Hz. You then just need to get an active TB to HDMI adapter to be able to use it as 60Hz. I could be wrong of course, it's been a while since I looked into it for mine.

The 2013 Mac Pro only supports HDMI 1.4, so you aren't actually getting 4k at 60Hz from that port.
Yeah, you clearly stated your connection and the screenshot shows that everything is set up correctly and works as intended on Windows.
Sorry, no idea then what the problem is with Monterey.
I had the same issue with an RX570 where I had to switch to a shorter HDMI cable to get 60Hz in macOS - for whatever reason.
Maybe the gurus @joevt or @Amethyst1 can shed some light on it.

Hi there, same problem.
I've purchased a MP 6,1 but it doesn't show 4k @ 60 Hz via HDMI port.
I've tried an adaptor thunderbolt 2 to hdmi but the mac literally crashed with refresh rate over 30 Hz.
I've seen the product you've mentioned.
Can be the solution to the problem? CAC-1170 or another model?
Thank you.

The 6,1 HDMI port only support 4K@30Hz
You need a miniDisplayPort to HDMI-Cable. If your Monitor has a DisplayPort, the Cable Matters mDP—>DP Cabel is working with 60Hz under macOS 12 and Windows 11. I will look what of my mDP—>HDMI cables will work.

As I wrote. Worked with macOS on 60 Hz with my 4K Eizo, but on Windows I got only 30 Hz
I've a LG49UN71 4K on MP 6,1.
The TV has no DisplayPort but HDMI 2.0.
Can 4K@60Hz work via HDMI to Thunderbolt 2?
Please write more exactly the port and direction.
The HDMI-Port on the MacPro 6,1 supports only 4K@30 Hz
A mini DisplayPort (Thunderbolt 2) to HDMI 2.x cable can give you 4K@60 Hz, but not every cable is working well.
I have not found any mDP -> HDMI cable that work with 60 Hz on macOS AND Windows.

Totally agree. I've bought several cables (mDP to HDMI; DP to HDMI), only one or 2 work fine and got me 4k@60Hz. The other can only produce 4k@30Hz.
I've bought these.
