![]() Here, I have two external displays connected to my laptop (whose internal display is turned off and is not showing). 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. Enter the percentage amount, click the button, then enter the number you want the percentage of, and then click equals. Percent button is used to find the percentage of a number. Enter a number, then click square root button. Disabling SIPĭon’t ask me why we have to disable a system security feature to tweak our displays, but that’s how it is. Square root button is used to calculate the square root of a number. 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). You will need to use the Terminal to deactivate SIP - what the heck is SIP?.So, take your time and if you don’t feel confident enough to do it by yourself, don’t do it by yourself. Playing with custom display resolution is not complex, but it’s easy to screw up and turn your monitor to full black without an easy way out.I will show how to check these in a moment. Also, you can’t use a screen refresh rate (the Hz thingy you will often see printed next to its resolution in product reviews) higher than what your screen is capable of– really, you don’t want to do that. SwitchResX is no magical wand, there is no way to turn your 1080p display into a 4 or 5K one. Maybe you want things on screen to be a bigger so you can see them from farther away? Or whatever. It has 3072 x 1440 resolution, a speedy 120 Hz refresh rate, up to 400 nits of brightness, and a steep 100 percent DCI-P3 color claim.Yesterday, I mentioned using SwitchResX to create custom screen resolutions when those provided by Apple are not enough to compensate for my bad eyesight.īut you don’t have to have a bad eyesight to create a custom resolution. The ThinkBook Plus Gen 3's ultrawide screen is a pretty beefy IPS. More recently, Acer's 2017 Predator 21 X used the 21:9 aspect ratio and a unique curve to claim supreme gaming immersion (again, with supported titles). The company's 21:9 Toshiba U845W laptop promised a superior experience for watching movies (at least ones made in the same aspect ratio) and multitasking. Horizontal resolution: pixels Vertical resolution: pixels Diagonal: inches (xx cm). If you have a resolution greater than 9000, it's covered. Attachment: ResHex3.PNG 10.9 KiB Downloaded 17042 times. This is calculated based on the IEEE 754 floating point standard. Toshiba tried to make it a thing in 2012. When you fill in multiple values, the combined hex value is shown in the Combined Hex window. We've seen ultrawide laptops before, but laptops with a screen that's wider than 16:9 are incredibly rare today. Lenovo says the ThinkBook Plus Gen 3 is the first machine to use a 17.3-inch 21:10 screen. Oh, and it has a second screen next to the keyboard, too. At CES this week, it announced a laptop with an ultrawide display. Lenovo, while also playing around with the likes of 16:10 laptop screens in other upcoming machines, is taking a wider approach. While the majority of laptops still use the 16:9 aspect ratio, we've seen many companies increasingly embrace taller aspect ratios over the last couple years.
