Override refresh rate

[CyberAP]

Some monitors support refresh rates past 144hz which is the highest one available out of the box. It would be nice to have an option to set a custom refresh rate if that's technically possible provided you have a cable and a monitor that can drive that refresh rate at a given resolution (I don't know if macs controllers can actually support that).

Clarification, this is not https://github.com/waydabber/BetterDisplay/issues/262, because it's not about dummy displays.

Custom refresh rates are possible now with EDID override support in BD (you can export the EDID, add the custom timing using AW EDID Editor - which is free - and then apply the EDID override). But I plan to add custom timing support in a future update in a more straightforward manner.

While you are at it, you could also add a force RGB mode option. This would eliminate the need for manual EDID editing for most users, since most probably use that feature to force 10-bit output.

@waydabber would that solve this issue too? On M1 macs, earlier versions of macos supported 4k 144Hz VRR with HDR but later versions don't support the same config with HDR. https://old.reddit.com/r/MacOS/comments/17hh371/hdr_option_is_not_available_on_macos_141_for_m1/

Sadly no, the issue is not EDID related, so this would not fix that.

Here is an explanation of the issue: https://github.com/waydabber/BetterDisplay/discussions/2706#discussioncomment-8609162

Ah bummer. Thanks for the detailed writeup!
