#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.
No need for additional software or SwitchResX as Mac Mini Mid 2010 supports via the display port 2560x1440. By an Adapter i.e. UGREEN Mini DisplayPort to HDMI+VGA Converter and reboot your computer. Plug your 1920x1080 display into the HDMI Port and the 2560x1080 LG WL500 B into the MiniDisplay Port.
Here is what they write at Apple Forum and that finally made it work. (Now I only need to check how to get completely rid again from SwitchResX as it isn't needed at all.

Go to Apple > System Preferences > Displays > hold the Alt (option) key and click on the Scaled button.
If the display does not work or you can not select a suitable resolution, then please answer the following ?'s.
What model is the LG display and what input connections does it have?
What cable and connection are you using between the Mac Mini and display?
FWIW the Mac Mini's Mini DisplayPort output supports the higher resolutions up to 2560x1600, while the HDMI port only supports up to 1920x1200. If you are using a direct HDMI to HDMI connection, then you may need to use a "Mini DisplayPort to DVI" or "Mini DisplayPort to DisplayPort" adapter from the Mac Mini's Mini DisplayPort output port.
