Refresh rates
After this page you will know which refresh rates are worth asking for and why 59.94 is not 60.
Last updated 22 August 2026
A virtual display advertises the refresh rate its spec carries. Catalogue entries bring the rates the real panel offers; a display you define yourself gets the rate you type.
Can you get 120 Hz over a remote session
Three things have to be true, and only the first is up to this app.
- The display has to run at that rate. That part is easy.
- The compositor has to produce frames that fast. macOS will, when something is actually drawing. An idle desktop does not, and that is not a fault.
- The client and the link have to carry them. This is where it usually stops. Screen Sharing negotiates conservatively and rarely commits to 120. Jump Desktop and Parsec do reach it on a good local network. Over the public internet, plan for 60.
Setting the display to a high rate costs nothing when the client cannot use it. It only means the display is not the ceiling.
The exact rates
The rates derived from NTSC are exact fractions, not decimals that got rounded. 60000/1001 is 59.940059940… and is written 59.94 by convention; 24000/1001 is written 23.976.
The app stores and formats what you give it, keeping the fraction when there is one and dropping it when there is not, so a display set to 59.94 says 59.94 and a display set to 60 says 60.
What the catalogue brings
Catalogue entries list the rates the real panel offers, highest first, which is usually what you want selected. A Studio Display XDR entry offers 120 and 60; a MacBook Air panel offers 60. The notes field on an entry is where the caveats live, such as which Macs can actually drive a panel at its highest rate.
Dynamic range is a separate choice
Refresh rate and dynamic range are both properties of the display, set in the same place, and they have nothing to do with each other. A display can be 120 Hz and standard range, or 24 Hz and reference mode. HDR covers the three ranges and what each one measures.
What is not here
There is no colour profile assignment. Displays use the system’s default colour handling, and nothing in MoreDisplays changes it. If your work needs a specific colour pipeline on a remote machine, this app is not the piece that provides it.
