However, the fact that there are a few scattered reports from other devices too like the MacBook Air and the Mac Mini M1 implies that the problem is more widespread than initially thought. And even when it does, it fails to wake up from sleep mode.Īnd going by the vast majority of reports, the issue does seem limited to the previous year’s MacBook Pro 16” 2019. Others have lamented that their PC can’t detect the monitor at all. The refresh rate also takes a significant hit and may max out at just 30 FPS.

Somebody else had a similiar problem?Īs apparent from the above complaints, 4K monitors seem to run at non-optimal resolutions like 1080p or even 720p when connected to devices like the MacBook. I restarted and plug / unplug the monitor already several times but it will not work.

#SWITCHRESX 4K SCALED TO 1080P UPDATE#

But after the latest update to big sur 11.1 its no longer possible to use 4K Resolution… even with SwitchResX the resolution is unavailable. I am connected via USB-C on both ends and the resolution was fine before the update. MacOs updated today (Big Sur 11.1)and I can no longer get the 4K resolution for my external monitor (LG $K HDR 43) which I need. It appears that macOS’ latest update virtually breaks external 4K monitor support, giving users a really hard time.

The macOS Big Sur update 11.1 was released on December 14, and right afterward, a slew of complaints emerged on the Apple forums about issues related to 4k monitor support. Original story (published on December 22, 2020) follows: Here, I have two external displays connected to my laptop (whose internal display is turned off and is not showing).New updates are being added at the bottom of this story……. 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.

#SWITCHRESX 4K SCALED TO 1080P INSTALL#

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.

#SWITCHRESX 4K SCALED TO 1080P HOW TO#

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. 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.
