In case someone is having the same problem with Big Sur: Regarding the access right, you need to be super user to create this file.Īfter a restart you should be able to see the correct resolution (2560x1080) in SwitchResX. System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-1e6d/DisplayProductID-59f1 I think you don't need to make every steps I did.
#SWITCHRESX 4K CODE#
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. Hope it helps Sry, I'm beginner and bit stupidoo. Now you just need to restart the MacBook and choose the correct resolution (2560x1080) in SwitchResX. I just copied to the systems folder like this: 'sudo cp DisplayYearManufacture-2015-DisplayWeekManufacture-1 /System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-1e6d'.Īfter that I renamed the file to match the product ID: 'DisplayProductID-59f1 '. you might save yourself a which cable are you using? I don't know how this works with other resolutions but for 2560 x 1080, if you have displayport and are not super techie (as I am not). Can even do 60Hz vs the reduced amount that was required to get SwitchResX working on High Sierra. Then I tried switching from HDMI to Display Port and now everything works fine on my old MBP without SwitchResX.
#SWITCHRESX 4K DRIVERS#
I reached out to the developer and he helped me troubleshoot but was ultimately told that the video drivers in Catalina had a restriction that was not in the previous OS and there was nothing that could be done, my machine just could no longer support 2560 x 1080.
#SWITCHRESX 4K UPDATE#
I tried all of the solutions above: uninstall and reinstall as a new user, update using EDID, renaming the relocated items file, etc. When I upgraded to Catalina SwitchResX no longer worked and I received the "Not activated - invalid?" message. I was using SwitchResX to display 2560 x 1080 on High Sierra without issue. Thought I should share in case anyone has the same issue I did.
