Increase refresh rate switchresx7/14/2023 The generally accepted level of refresh rate that leads to a satisfying image depends on the application. This number of changes per second is measured in hertz (Hz). The faster the refresh rate, the more times the image can update every second and the smoother the image will look. The refresh rate of a monitor is the speed (rate) at which the monitor’s image changes (refreshes). But what exactly is refresh rate and how does it relate to other aspects of monitor technology, such as panel type and response time? Read on to find out. Here, I have two external displays connected to my laptop (whose internal display is turned off and is not showing).What does refresh rate mean, and how does it affect gaming? We explain 144Hz monitors and beyond, and why more hertz isn’t always better (but usually is).įor years, the refresh rate has been the go-to number for gamers when buying a monitor. Select your display in the left pane and click the Custom Resolutions tab. In a Terminal window type: csrutil enableĭone. In the menu bar, go to Utilities -> Terminal to open a shell, and type:Īfter you’re done playing with SwitchResX, reboot the Mac and Cmd+R again.Release the keys and let it finish the boot process. Restart your Mac, holding Cmd+R until you see the Apple logo.The one thing to remember, is to turn SIP back on, after you’ve finished creating your resolution. Disabling SIPĭon’t ask me why we have to disable a system security feature to tweak our displays, but that’s how it is. Or, like me, if you’re bad with numbers use a resolution scale calculator to be on the safe side and get a list of compatible resolutions for your screen, based on its default resolution. Google you model if you’re not sure what it is. It’s 16:10, in my case, many displays are 16:9. Unless you want to see things distorted on your screen, your new resolution must use the same ratio as your display. But I know Active Horizontal, Active Vertical and Scan rate (the one defined in Hz, the rightmost at the bottom of the screen, not the one in KHz next to it) are the values to keep in mind. I have no idea what all these values mean. In the left pane, select your display and click the Current Resolutions tab. I repeat: you must not use settings over what your display is physically capable of, or things will go wrong, and getting them back in order is no fun if you don’t have a second screen.Īfter installing SwitchResX, go to System Preferences->SwitchResX. You need to install SwitchResX before you can do anything. Do not forget to turn it back on after you’ve created your custom resolution(s).
