  1. 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) <?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 + RGB)</string> <key>IODisplayEDID</key> <data>AP///////wAQrG/QTEE0MCkZAQSlNx94JkRVqVVNnSYPUFSlSwCzANEAcU+p QIGAd4ABAQEBVl4AoKCgKVAwIDUAKTchAAAaAAAA/wBYWFhYWFhYWFhYWFgK AAAA/ABERUxMIFUyNTE1SAogAAAA/QA4Vh5xHgEKICAgICAgAKM=</data> <key>DisplayVendorID</key> <integer>4268</integer> <key>DisplayProductID</key> <integer>53360</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> 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.
