#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.

Does anyone have SwitchResX settings for the LG 34UC99 Curved UltraWide QHD (3440x1440) for HIDPI?

@minimumnz I'm not sure what you're asking for, but I was looking for 75Hz support as it only detected up to 60. I took this table from the manual

added a custom resolution where I changed the scan rate field for horizontal to 110,770 (this automatically updates the scan rate for vertical), and I checked the positive sync.check box for the vertical column (as according to the table in the manual). Seems to work fine here.

I just copied to the systems folder like this: 'sudo cp DisplayYearManufacture-2015-DisplayWeekManufacture-1 /System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-1e6d'.
After that I renamed the file to match the product ID: 'DisplayProductID-59f1 '.
Now you just need to restart the MacBook and choose the correct resolution (2560x1080) in SwitchResX.
Hope it helps =)

@nelsoncvides Sry, I'm beginner and bit stupidoo. Can you please write the whole code for the terminal? And I have problems with access right - I can't copy that file to the folder on mac. Thank you.

I think you don't need to make every steps I did. You just need to create this file
/System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-1e6d/DisplayProductID-59f1

with this content:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>DisplayPixelDimensions</key>
	<data>
	AAAKAAAABDg=
	</data>
	<key>DisplayProductID</key>
	<integer>23025</integer>
	<key>DisplayProductName</key>
	<string>SwitchResX4 - LG ULTRAWIDE</string>
	<key>DisplayVendorID</key>
	<integer>7789</integer>
	<key>SwitchResX backuped settings</key>
	<dict>
		<key>DisplayProductID</key>
		<integer>23025</integer>
		<key>DisplayVendorID</key>
		<integer>7789</integer>
	</dict>
	<key>default-resolution</key>
	<data>
	AAAKAAAABDgAPAAA
	</data>
	<key>dspc</key>
	<array>
		<data>
		izkAoKA4GUAwIDoAAAAAAAAa
		</data>
	</array>
</dict>
</plist>

Regarding the access right, you need to be super user to create this file.
After a restart you should be able to see the correct resolution (2560x1080) in SwitchResX.

Thank you!!!

In case someone is having the same problem with Big Sur:

You can not edit /System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-1e6d/DisplayProductID-59f1 since it's readonly. So you just have to add this mentioned file after mounting the drive using this step: https://apple.stackexchange.com/questions/395508/mount-root-as-writable-in-big-sur

Anyone else have the issue of their ultrawide not displaying anything (but still receiving a signal as the display doesn't go to sleep) on a 38WN95C via ThunderBolt 3?

The monitor works fine if the lid is open, OR a second HDMI monitor is also connected to the Macbook. With just the 38WN95C connected, the display is blank if I close the lid. After looking at the switchresx logs in the console viewer it seems to be warning on "Invalid display ".

Anyone got any tips?

This worked great on my Mac Mini (late 2012) and my LG-34WL500-B ultra wide monitor. Thanks Erich for a tremendous job!

After using High Sierra on a 2017 Razer Blade Pro with 4K display, using QuickRes to achieve a readable resolution, moving back to an Intel MacBook Pro was frustrating for a bit. Experiencing how Windows 10 can easily adjust resolutions on the main display, but easily drive 2 UPerfect 15 inch 4K displays with needing specialized software like DisplayPort to achieve changes in resolution by percentages made the limitations in choices in Big Sur underpowered.
This software, running as a daemon, fixed everything. I now have similar functionality in macOS. I know the daemon function will not push frame rate high enough to play demanding games. However it does make it possible to get work done by being able to see more. After seeing it work today for just a few minutes was enough to buy a license.
I know a lot of this can be done at CLI, however this software fills in the missing part in macOS. Thank you for making this software!

I upgraded my macbook air 2015 OS to Big sur and I'm having the same issue with Switchresx when I add a custom resolution I get status: not installed. Any advice or help will greatly appreciated!!!!

Hi all! All nice working on mac mini 2012 with LG 29 UM58 SwitchResX. But before the settings SwichResX - you need to specify the Ratio as wide in the settings of the monitor itself. Best Regards!

Thank you 👍 , it works for me LG WK600 29"

hey guys, im running 3840 x 2160 @ 50 hz or hidp 1080 on 13" MacBook Pro mid 2014 Mac OS Catalina. just wondering if I should upgrade to Big Sur. will it affect my usage?

Much appreciated! Fiddled around for about an hour and had serveral restarts til I found this repo. Thanks to it my LG 29WK500 connected to a Mac mini late 2012 works now like a charm. Also all other 21:9 resolutions showed up immediately !

Thank you...finally work on my Macbook MD101 and LG 34WL500-B... after trying with soooo many adapter...

I have an external monitor; LG 25UM58-P, 21:9 Ultrawide. I recently updated my mbpro mid 2012 non-retina. I managed to disable SIP and install macOS Big Sur by using OpenCore Patcher, can't seem to get the native resolution 2560x1080p in SwitchresX. it was fine when I was in macOS Mojave. is there a work around?

!!!!! thankyou 👍 😄 image settings worked with LG29kw500

Love you so much! Thanks!!!!!

Hello Guys,

I have a problem when tried to install a ultra wide resolution using SwitchresX in macOS Big Sur 11.6.1, and discovered that the path is readonly. But I found a patch that fix it, in the url:

https://gist.github.com/adaugherity/7435890

After applying the patch, just doing sudo ./patch-edid.rb, SwitchresX was able to write in the path /Library/Displays/Contents/Resources/Overrides/DisplayVendorID-1e6d/ saving the file DisplayProductId-7714, and my LG UltraWide now is using the resolution 2560 x 1080 in my MacBook Pro Late 2012.

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.
https://discussions.apple.com/thread/251212226?answerId=252323522022#252323522022

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.

I have t revise the above comment of ours. It worked only until we rebooted the second time and then no more. We don't know why it was displaying correctly after we had changed from HDMI in MacMini to the MDP with adapter UGREEN MDP>HDMI+VGA - It worked the first time only, unfortunately. We then rebooted again and got again the 1920x1080 for the ultrawide LG screen. We write to the SwicthResX Support and will see if they have any idea why it worked only one time - the first time after we started using the MDP>HDMI adapter.

@ipreppress Could you please send me a screenshot of your settings for the mac mini 2012 - I have one in Mid 2010 and can't get it working and seeing your settings might help Thanks.
By the way when I have switchresx daemon running then my github does not work like usual i.e. I can't post "@" via the mentions button and also when I like to edit a comment it shows me only an empty dropdown. On the computer with no switchresx installed everything works fine.

Thanks This worked great on my MacBook Pro 13 2017 Touch Bar and my LG-34WQ500 ultra wide monitor.

• 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?

I installed the application and it worked well on the first day, then entering pages with many colors or backgrounds with movement, or being on YouTube, the screen began to show green colors and then turn off, I have tried everything and I have not been able to solve it, any idea of how to solve it? Thank you.

I'm not quite sure if it matches my problem, but I'll post my experience and attempts to set up an external monitor for Mac mini M2 pro (MacOS 13.7.1):
I purchased an additional third micro-monitor for specific tasks for DAW performance monitoring (reaper & Logic pro X) like this:

• LESOWN 2.5 inch wide LCD w/HDMI-socket.
  vendor ID YXS-6713;
  DisplayProduct ID 6666;
  After arriving and unpacking, I couldn't run it on iMac 11.3 (MacOS 10.13.6 High Sierra and 11.7.6 Big Sure), but its functionality was checked by Win10.
  With the help of SwitchResX I managed to run it on mini M2 pro MacOS 13.7.1 Ventura.
  

But due to my inexperience, I myself did not understand how I set the monitor resolution to be too high 3840x880. Which was subsequently locked by the system:

and all other options for deleting and reinstalling SwitchResX did not allow me to restore or switching of lower LCD resolution settings for normal viewing of information at screen windows.
But in the end, I managed to restore the desired initial settings in SRX with a screen resolution of 960x220, by switching in MacOS:

• system settings -> Desktop & Dock settings -> Displays have separate Spaces => ON/OFF.
  But the problem with locking the new screen resolution still remained! Although I expected this...
  carrent settings:
  
  And for the next change, it is necessary to repeat all manipulations with switching the resolution parameters according to the above recommendations and because custom resolutions aren't supported on Apple Silicon.
