Hey, thanks a lot for the tutorial and the files, this is exactly what I have been looking for!

 

However, I am running into a problem:

 

When trying to move the "DisplayProduct..." file into the /System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-10ac/ folder, I do not get permissions to this. I tried granting permission both via Finder and via Terminal, did not work (i have no permissions for changing permissions...)

 

Does anyone have a hint how to work around this?

 

Thanks a lot in advance!

Found the solution for gaining permissions to the Systems folder:

Hi,

my new Dell U2515H is connected via DisplayPort to a Intel HD4600.

I like this monitor very much but with the native resolution of 2560x1440 pixel system-font looks really small.

So I activated HiDPI from the terminal:

sudo defaults write /Library/Preferences/com.apple.windowserver.plist DisplayResolutionEnabled -bool true

but with the "1280x720 HiDPI" resolution the screen is to small

 

After a long search I found a solution - display overrides.

 

For this I put an override-file 'DisplayProductID-d06f' with the code below to

/System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-10ac/DisplayProductID-d06f

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>DisplayProductName</key>
  <string>Dell U2515H (HiDPI)</string>
  <key>DisplayVendorID</key>
  <integer>4268</integer>
  <key>DisplayProductID</key>
  <integer>53359</integer>
  <key>scale-resolutions</key>
  <array>
    <data>AAAPAAAACHAAAAAB</data> <!-- 3840x2160 to get 1920x1080 HiDPI -->
    <data>AAAMgAAABwgAAAAB</data> <!-- 3200x1800 to get 1600x900 HiDPI -->
    <data>AAALQAAABlQAAAAB</data> <!-- 2880x1620 to get 1440x810 HiDPI -->
  </array>
</dict>
</plist>
 

The Monitor use another ProductID if it's connected to HDMI.

Therefore I need another override file. To verify the ProductID, I use this from terminal:

ioreg -l -w0 -d0 -r -c AppleDisplay | grep ID | grep -v IO

This override has a patched EDID to support RGB color mode with HDMI (see http://embdev.net/topic/284710 for more info)

  </array>
</dict>
</plist>

Reboot and done

 

For easy resolution switching I wrote a command-line tool based on RetinaDisplayMenu.

I put SetDisplayResolution to /usr/local/bin and use Karabiner to create the keyboard shortcuts.

From my private.xml

Have Fun!

 

Hi

My Dell u2515 is connected via DisplayPort to a Intel Iris Graphics (mac mini late 2014)

I did all operations in instruction, but in my screen option add only screen resolution 1600x900HiDPI. I can’t set 1920x1080 HiDPI of screen resolution.

help me please.

thanks

Did you managed to fix it?

I have the same problem, I cant use 2560x1440@144Hz in Catalina...
