#SwitchResX Settings for LG 21:9 UltraWide

SwitchResX is a utility that allows users to override the default resolution settings in OSX. For more information, including download links, vist http://www.madrau.com/ .

##Disabling System Integrity Protection (SIP)

If you are running OSX 10.11 or higher, SIP must be disabled. To disable SIP do the following:

• Boot into the recovery partition by pressing CMD + R when starting up your Mac.
• Once in recovery mode, open a terminal window.
• Type the command csrutil disable
• Reboot

##Adding Custom Settings

• After launching SwitchResX, select the external monitor from the list on the left.
• Select the 'Custom Resolutions' tab.
• Add a new custom resolution be clicking the + symbol at the bottom of the window.
• Adjust the settings to match the appropriate PNG provided in this gist.
• Press 'Ok'
• Close SwitchResX and save when prompted.
• Restart your Mac.

After following these steps, you should be able to adjust the resolution of your external monitor through the 'Display' window in System Preferences.

• Add new custom resolution and fill values as in a text file (see screenshot below)

Thank you!! I have the same monitor as yours and just copied your configs : ), I also exported the file just to confirm.

Does anyone know if I can follow the same steps for the Samsung monitor?

Thanks. I set the parameters from the screen and rebooting. Everything stood up perfectly on the LG 29WN600-W, native resolution and clear fonts. Configured on macOS Big Sur on Mac Mini 2012

Can't set the res in a mac mini 2012 with LG Ultrawide 21.9. Its says resolution 'not installed' in swicthresx. AnyIdea how to solve?

I just tried app for the first time, and there's a serious bug/issue that I can't find a solution for.
It breaks the ability to command-click items in the Finder for multi-selecting.
I cannot find a work-round, but if I quit the SwitchResX Daemon, the issue goes away, so it's definitely a bug with the app.
There's nowhere I can change the key binding for command-click to fix this.
The closest setting I can find is under "Menus", "Contextual Menu", and I added "option" for "Command=option", but it doesn't fix the problem.
Even is I un-check the contextual menus to disable them, I still cannot command-click Finder items on my desktop.
Is there another fix, or something I'm missing?
