I just purchased a monitor with 240hz refresh rate. I'm not a gamer and am trying it out to see if it helps with migraines from too much screen time. I'm not particularly tech savvy. I just set it up, but it says it's at 120hz. When I go to Display Preferences on my MacBook, the refresh rate options are 50, 60, and 120 hz.
- Monitor: Alienware - 24.5" IPS LED FHD FreeSync and G-SYNC Compatible Monitor - model # AW2521HFL
- Laptop: Macbook Air, MacOs Catalina, 2017
- Connected via HDMI cable (came with the monitor) to Insignia Mini Display Port to HDMI Adapter for Mac (4k ultra HD, just purchased)
