Instead, I opted for the Dell UltraSharp UP2414Q. It’s a beautiful display, and normally I’m opposed to buying nearly any item from Dell, but I sure am lovin’ this thing. It’s default resolution is a staggering 3840×2160, and EVERYTHING is tiny in that mode. To get it working in OS X as a Retina display I had to follow these steps:
- Connect the monitor via DisplayPort
- Run the following command in Terminal:
sudo defaults write /Library/Preferences/com.apple.windowserver.plist DisplayResolutionEnabled -bool true
- Restart the computer
- Open Display settings on another monitor (your 4K display won’t work because there are two 30hz settings for the default resolution, one of which doesn’t work).
- On another display (assuming you have more than one, like I do), hit “Gather Windows” at the bottom of the Display settings window.
- Switch to the window for your new monitor’s settings.
- Click the radiobutton for “Scaled” resolution.
- Select the new display mode listed as “1920 x 1080 (HiDPI)
And that’s it! You now have an ultra cool Retina display! While really amazing looking, this is for more than just kicks. Development in Retina is a different world. The 2x scaling factory is requiring a lot of code changes for my products, and will make them even more enticing for my customer base.
