HDMI currently supports up to 144Hz. Even HDMI 1.4 (2009) could reach 120Hz.

However, compatibility is hit and miss in general. You may have had luck replacing one or more cables or adapters, but switching to displayport is likely to get the best results, anyway.

HDMI supports >200hz if you've got compatible hardware (HDMI 2.1).

It's admittedly hard to get this hardware unless you're willing to pay for the top of the line versions, but it does exist.

Budget hardware usually works better with display port however, that's true
