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. I am very lost and almost give up.Ĭould anyone tell me if it will ever work? if it is not, I will just stop trying.Īlso, please let me know if I need to disable (reverse) this attached patch code if I do not need to use it anymore. I tried this patch file ( ), disable SIP, install SwitchResX and yet it doesn't work. However, my friend's 2015 mbp can run easily 4k 60hz with my setup. However, I was so disappointed when I could only run 720p 59.5hz while the other options only work at 29.5hz and below.Ĥk 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. 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. 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. Hi guys, need a little help here, appreciate if you guys could help. 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. 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.
