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 '. In my case value of PixelClock in EDID report was 181,25 MHz If no luck – do item number 6 again and again.

I had to try a few different values for the Hz before seeing that it actually could only handle 53Hz.

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. Just fixed my issue thanks to some of the help I found on here in conjunction with this page of the FAQs from SwitchResX.
