No. The M2 MacBook Air only supports 60Hz. It cannot support anything greater.

Other models can support greater refresh rates at different resolutions. The M2 cannot.

So if I get a 165hz display can't I get that framerate when I connect it to my M2 MacBook Air? Wow.


Why would you expect to get a 165 Hz refresh rate when Apple advertises that the computer supports a 60 Hz refresh rate?

"Simultaneously supports full native resolution on the built-in display at 1 billion colors and: One external display with up to 6K resolution at 60Hz"


Use an external display with your MacBook Air - Apple Support

(2022 – Monterey version)

"You can attach one external display with up to 6K resolution at 60Hz."


If the Mac is willing, say, to drive a 1080p display at 75 Hz - it's Christmas. You got more than the published specs promised. But from what I've seen in Technical Specifications and Support articles for newer Macs, when a Mac is able to drive a monitor at 144 Hz or more, that's specified openly. And it often comes with a cost, like "if you have a monitor with a high refresh rate, it reduces the total number of external monitors you can use at one time."

The world does not revolve around 165 Hz monitors.


165 Hz is not an integer multiple either of common video refresh rates, or of the number of frames per second which Hollywood used when shooting many old movies on film. 60 Hz or 120 Hz make much more sense for a television set, or a monitor used to watch TV shows and movies. 60 Hz because it is standard, 120 Hz because that would allow displaying 24 frame per second source material without a 3:2 pulldown.


Other than people who are impressed by large numbers for their own sake, I suspect that the only people who really care about 165 Hz refresh rates are fast-twitch gamers.
