SwitchResX Configuration

#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.

I managed to connect my ultra-wide LG 25UM58 to my old macbook pro with intel graphics via belkin mini-dp_>hdmi converter and a generic hdmi cable. After applying this patch: https://github.com/Floris497/mac-pixel-clock-patch-V2, full 2560x1080 resolution became available in SwitchResX automatically. I'm enclosing the timings for reference, but you probably don't need them with the patch

Hi. I have a LG29UM58-P and a Late 2012 Mac Mini. The monitor only has 2 HDMI ports and an audio port.

I am unable to get the 2560x1080 resolution going straight to the HDMI port on the mini but I thought that I could drive that thru the Mini display/Thunderbolt port. So I got one of these... https://us.macally.com/products/mdhdmi4k

I have hooked it up to my 2015 MacBook Pro Retina and it gets the 2560x1080 resolution and looks awesome, but want this as my main screen for my mini.

Am I missing something? Can this be done with my setup?

Thanks.

After following these instruction I got it working. I tried different instructions a couple days ago which ended with an "Out of Range" error and a days worth of work trying different ways to fix it.

Didn't need the MacAlly adapter. Going to take that back and pay the $16 for SwitchResX.

According to @debdude about patch, I didn't install the patch, and tried to apply his setting. It didn't work on my setting (29UM68-P) and it's marked as invalid on SwitchResX. I guess I have to use the patch (as I really need 60Hz refresh rate).

Edit: Turned out even installed a patch, new native setting isn't showed up. I have to stick with the original setting of author of this gist to make it work without stretching. I have 10.12.5. Thanks

haxpor commented Jun 10, 2017

@skiabox FYI: I tried to achieve 60Hz, didn't work for my LG 29UM68-P. The best possible I can do is the topmost setting. I tried debdude's setting, but SwitchResX didn't accept. But I think that's because it's the limitation on HDMI 2.0 which chained via mini display. Anyway, all else works fine for me.
@aldwin Thank you! I can confirm that this works. I also upgraded to High Sierra. What I did is the same. If you don't want to maintain that new user, that's fine. After switching to install SwitchResX as new user, reboot, make sure everything fine. Then log out and log in as your main user (usually Administrator). Finally remove that new user you used to install SwitchResX, and if needed select 3rd option to delete all user home folder. The latter just make sure you install SwitchResX globally for all users. Everything works the same.

I suspect that this setting (pixel clock) is what's keeping my LG 4K TV from displaying correctly. Does anyone know how to determine what pixel clock settings correspond to one's TV? My tv is an LG 43UJ6300 4K LED TV.

Here's a summary of the issue:

I’m working on getting an i5 Mac mini to display to an LG 4K tv for a studio we’re building at the office. I bought a Club 3D mini DP to HDMI adapter and downloaded/bought SwitchResX to unlock and utilize the higher resolutions and refresh rates. I can get the highest resolution and frame rate combination to work through SwitchResX, but as soon as I reboot the Mac Mini, after the Apple logo loading bar screen passes, the screen flickers and flashes green. I then have to unplug the HDMI cable from the adapter and plug it directly into the Mac Mini which then displays the Mac’s desktop. I can then plug it back into the adapter to take advantage of the SwitchResX resolution for 4K. I’ve scoured different forums to no avail. Has anyone seen anything similar? Any help is appreciated.

HIGHSIERRA FIX!

I had the same problem, but I was able to fix it by resetting the factory settings in switchResX, then removing system preferences and deleting all records (i used cleanmymac3). After that, I created a new user and, following the same procedures, I was able to configure everything correctly. So I delete the user and it remained perfect. (Sorry for the translation, I used google translate)

ps: @haxpor, thanks for the tip, I got it because of your comment

Eu tive o mesmo problema, mas consegui corrigi-lo, redefinindo as configurações de fábrica no switchResX, removendo das preferências do sistema e excluindo todos os registros (usei o cleanmymac3). Depois disso, criei um novo usuário e, seguindo os mesmos procedimentos, consegui configurar tudo corretamente. Então eu exclui o usuário e permaneceu perfeito.

---- Update Nov 21 2017
Now it works.

I contacted Stephane Madrau and he explained that changes were made to SwitchResX. If you had been using it for longer than 10 days, while updating to High Sierra it will stop working. After purchasing the license (US$ 16.00), it works. Not ideal, but it's the only option I found.

Fix High Sierra Steps:

  1. Uninstall switchresX app, try to uninstall with app cleaner and try clean with MyCleanMac
  2. Create a new mac user with admin permissions
  3. Log out current user and login with your new user admin
  4. Install switchresX in new admin profile(install in all user when the installator asks you) Note: Follow the top steps in this gist/page(README.md)
  5. Log out admin user and login with your real user
  6. Install switchresX
    Note 1: Follow the top steps in this gist/page(README.md)
    Note 2: If for some reason your latest switchresX uninstall doesn't work properly, you need to find a license number to switchresX to save new changes.
  7. Launch switchresX
  • if in your custom resolutions tab has not your latest monitor configuration do the step 4
    screen shot 2017-12-03 at 8 46 04 pm
  • If you have your latest configuration simply choose the configuration on you current resolutions tab
    screen shot 2017-12-03 at 8 45 08 pm
  1. Restart your mac

NOTE: The above steps work in my case I hope works for you.

My fix:

  2. Create a new user on the mac (as an administrator)
  3. Reboot, and log in as the new user
  4. Download switchresx and install for all users, then enter in the settings noted in this image

I was having trouble with my Late 2011 MacBook Pro on High Sierra and LG 29UM69G-B not letting me choose the correct resolution and instead defaulting to a very stretched 1920x1080. Bought a Firebolt to DisplayPort cable and it is now working perfectly. This is the one I got:

https://www.amazon.co.uk/gp/product/B01N12FB0W/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Item Name: Mini DisplayPort to DisplayPort 4K@60Hz 3M Cable, Benfei Mini DP(Thunderbolt Compatible) to Display Port Adapter Male to Male Gold-Plated Cord for MacBook, Lenovo, Dell and other Brand

Alternatively, I did manage to create a SwitchResX profile that more or less worked, although it was at 53hz instead of 60hz and the monitor showed me a warning to tell me that. I didn't bother resolving it though because I had already ordered the new cable. For anybody interested, here are the settings:

I'm not sure if it works as I gave up bothering with HDMI on my late 2011 MBP but heres what my LG 29UM69G reports to SwtichResX over DisplayPort (I use HDMI 2.0 for my Linux/Windows PC instead of my prefered solution with HDMI for the MBP and DP for the way newer PC (luckily HDMI 2.0 still supports FreeSync on Windows :))).

The 75Hz setting requires FreeSync: Enable it in the Menu -> Picture -> Game Adjust -> FreeSync -> On

In general I'd suggest to use a Mini DisplayPort to DisplayPort cable for this screen (if your MacBook has Thunderbolt 1/2 it should support the full resolution out of the box -> if it's occupied with something else or you have a Thunderbolt Dock without a second TB connector you might have to go for HDMI).

I hope this helps (and works). Would be nice if someone could report back!

This is my little solution for LG 29WK600

  1. Open SwitchResX and press "Export EDID"
  2. Save file to your desktop or where you like
  3. Open in text editor and find your resolution stack
  4. Add new custom resolution and fill values as in a text file (see screenshot below)
  5. Save settings and push "Apply Now" button in right bottom corner
    If you lucky – Resolution will changing and status will sets to "Active"
    If nothing going on you need scale down "Pixel clock" value:
  6. Decrease value by one and repeat item number 5
    If no luck – do item number 6 again and again...

In my case value of PixelClock in EDID report was 181,25 MHz
But working value is 165 MHz

I tried the patch, and also installed the program, but i don't get the screen! i see when i connect the mbp screen shuts down for half a second. Also I tested the same adaptor and cable with a generic monitor and it works.

Just fixed my issue thanks to some of the help I found on here in conjunction with this page of the FAQs from SwitchResX. I started having my issue after upgrading to Mojave, and I've had black banding on the side of my monitor for like two weeks now. After disabling SIP, and going through the other steps on here, I realized that the actual issue was that my mid-2012 MacBook Pro connected to an LG 34UM68-P 34-Inch 21:9 UltraWide via Mini DisplayPort to HDMI didn't actually support 2560 X 1080 @ 60Hz. I had to try a few different values for the Hz before seeing that it actually could only handle 53Hz.

I kept seeing "Not Activated - in..." for my status after saving and rebooting, and it took a while to figure it out, but that just meant "Not Activated - invalid," meaning that the custom resolution wasn't a valid one. After trying a few, and rebooting, the picture below was the outcome, so it looks like 53Hz is the max my setup can run with, but it looks great, so I'm not complaining.
switchresx screenshot If anyone else is in a similar situation, it might benefit you to try a few other values that are less than 60. I'd be happy to help if you have similar issues with a similar setup!

Also, please support the dev!

I have a Late 2011 MacBook Pro connected to an LG Ultrawide 25UM58, I installed SwitchResX and I've been trying for hours to make it work in 21:9 but every time I add a custom resolution and click on Apply Now to try it my monitor image gets upside down (without any change on resolution) and SwitchRes displays this warning on my MacBook screen:
"The Display configuration has been modified
SwitchResX has detected that the display configuration has changed. All unsaved preferences are thus invalid and have been discarded."
Then I click OK and the screen goes back to normal, I tried many values and configurations and the same thing happens all the time, I already deactivated SIP and my MiniDP to HDMI adapter does support 21:9 (tested on my Late 2013 iMac that supports it natively) what should I do?

this is very important! in case anyone is stuck upon having a working version of your widescreen, and suddenly it stopped working:

  • Have a backup of your previously working settings, or at least remember where you took them from

OR

  • Use @Dreamer-4pda suggestion upon starting point: in fact, use the parameters, as suggested, and just duplicate the custom resolution and change the vertical Hz value

And, the most important thing is: have another video adapter available to test. In my case, my LG 29UM68-P worked connected to a j5 create hub, but one day it just stopped working. I tried changing settings (custom resolutions) at SwitchResX, and always got back a "Not activated - invalid?" message back.

After days, I read some comment, regarding trying to connect directly to thunderbolt/displayport. I had another adapter (hdmi/vga to displayport), connected my monitor to it, and the very same custom resolutions just worked!

It was just an adapter issue. Wish I have had this under my vision before trying for days to fix SwitchResX.

This is my little solution for LG 29WK600

  1. Open SwitchResX and press "Export EDID"
  2. Save file to your desktop or where you like
  3. Open in text editor and find your resolution stack
  4. Add new custom resolution and fill values as in a text file (see screenshot below)
  5. Save settings and push "Apply Now" button in right bottom corner
    If you lucky – Resolution will changing and status will sets to "Active"
    If nothing going on you need scale down "Pixel clock" value:
  6. Decrease value by one and repeat item number 5
    If no luck – do item number 6 again and again...

In my case value of PixelClock in EDID report was 181,25 MHz
But working value is 165 MHz

I'm not sure if it works as I gave up bothering with HDMI on my late 2011 MBP but heres what my LG 29UM69G reports to SwtichResX over DisplayPort (I use HDMI 2.0 for my Linux/Windows PC instead of my prefered solution with HDMI for the MBP and DP for the way newer PC (luckily HDMI 2.0 still supports FreeSync on Windows :))).

The 75Hz setting requires FreeSync: Enable it in the Menu -> Picture -> Game Adjust -> FreeSync -> On

In general I'd suggest to use a Mini DisplayPort to DisplayPort cable for this screen (if your MacBook has Thunderbolt 1/2 it should support the full resolution out of the box -> if it's occupied with something else or you have a Thunderbolt Dock without a second TB connector you might have to go for HDMI).

I hope this helps (and works). Would be nice if someone could report back!

Folks - I got this to work using the suggestion by @ohboyd above. My Specs - macOS Catalina 10.15.13 - macbook pro 2012 15 inch - LG ultrawide 34UM61 - thunderbolt to hdmi. Use switchResX to export EDID settings. Then set these in custom resolutions in ResX - but set the frequency to 53 Hz. That is the highest frequency it will go to for 2560 x 1080 resolution - I can live with that. For me, the resolution on the LG seems to work properly only when the mac lid is closed.

For those using Catalina and having trouble with LG UltraWide displays, try not to use any HDMI adaptor between Mac and Display, instead connect the LG UW Display using the DisplayPort on its back, to the Display Port on your MacBook (considering it has one display port) and Catalina natively detects 2560x1080@60Hz and 2560x1080@75Hz.

Just select the resolution and use it. There is absolutely no necessity to any other trick, configs or software [ like SwitchResX ].

Only works perfectly if connected via Display Port cable.

But if using any HDMI adapter, all the above replies and configurations must be done.

Launching SwitchResX on MacBook Pro 2018 with Catalina installed, will do nothing. The application gets quit as soon as possible without any hint. I also tried it out in the terminal. Maybe its worth that the Download-Link on the official madrau.com Website will result in an 404 though.
I found another Download path on a german IT-News-Site (Heise.de), but this will end up that the app won't start.
Any ideas of the state of SwutchResX? Or are there any alternatives available?

Hardware-
Monitor: LG 25UM56-P

Would I be able to use this monitor at its native resolution if I get a mini display port to HDMI cable (https://www.amazon.com/Rankie-Mini-DisplayPort-Cable-Ready/dp/B00YONKZ72)?

After updating my MacBook Air (Mid 2015) to Catalina my monitor (LG 25UM58-P) resolution changed to 1920x1080. I tried a lot of stuff (using SwitchResX and other apps) without any success. Then I saw a new folder in my desktop called 'Relocated Items' . Inside this folder there's another one with the DisplayVendorID-1e6d.

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 '.

Hi guys, need a little help here, appreciate if you guys could help.
My 13" MacBook Pro mid 2014 display broke down weeks ago, I ordered a Dell U2720Q with a native resolution of 3840 x 2160 @ 60hz.
I am running Mac OS 10.15.4, connected my mbp to the display using mini dp to dp in attempt to get 60hz display. However, I was so disappointed when I could only run 720p @ 59.5hz while the other options only work at 29.5hz and below.
4k @ 60hz is not what I wanted, I only want to run 2560 x 1440 @ 60hz or 2304 x 1296 @ 60hz and yet my mbp doesn't allow this to happen. However, my friend's 2015 mbp can run easily 4k @ 60hz with my setup. That is ridiculous!

I tried this patch file ( https://raw.githubusercontent.com/Floris497/mac-pixel-clock-patch-V2/master/CoreDisplay-patcher.command ), disable SIP, install SwitchResX and yet it doesn't work. I am very lost and almost give up.
Could anyone tell me if it will ever work? if it is not, I will just stop trying.
Also, please let me know if I need to disable (reverse) this attached patch code if I do not need to use it anymore.

Thank you!
