I follow your comments and it created a 2560x180  but no matter how many times y click on the resolution it doesn't change 

s 1720 * 720 useable and which GPU are you on? Yes, Radeon Pro 560X 4 GB Intel UHD Graphics 630 1536 MB

i really didnt know how to compile it but i tried sudo mount -uw/ killall Finder and click the desired resolution but still dint work :(

thanks for the quick explanation, it didnt work on my mac as well, i will stick with the none hpdi until i found a workaround

Hi, this is my output, am the monitor is connected using thunderbolt 3 | | | | | "IODisplayPrefsKey" = "Alias:0/AppleBacklightDisplay-610-a040" | | | | | "IODisplayPrefsKey" = "IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/PEG0@1/IOPP/GFX0@0/ATY,Palena@1/AMDFramebufferVIB/display0/AppleDisplay-1e6d-772b"

/System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-1e6d/DisplayProductID-772b [systemlibrary.txt](https://github.com/usr-sse2/RDM/files/5210875/systemlibrary.txt) this one /Library/Displays/Contents/Resources/Overrides/DisplayVendorID-1e6d/DisplayProductID-772b doesn't exists

also maybe important to mention i previously used https://github.com/xzhih/one-key-hidpi

hi, deleted the file, this erased the resolutions, i recreated the resolution reboot the machine and if i click the resolution didnt change osx 10.15.6 System Integrity Protection status: disabled....

its funny the built in display can reach the desired resolution on hpi but the external cant, but i can have a resolution twice, any who, i tried the install...
