Making an External Display a Monitor, Not a TV

Erica Sadun:

What I didn’t expect was how awful the text looked on it. I hooked up the monitor to the MBP using my Apple TV HDMI cable. The text was unreadable. I use similar TV-style monitors for my main system and they display text just fine. However, I’m using normal display ports and cables for my mini. This is the first time I’ve gone HDMI direct.

All the searches lead to this ruby script. The script builds a display override file containing a vendor and product ID with 4:4:4 RGB color support. The trick lies in getting macOS to install, read, and use it properly. That’s because you can’t install the file directly to /System/Library/Displays/Contents/Resources/Overrides/ in modern macOS. Instead, you have to disable “rootless”.

Question: Is there a 30-inch monitor with 16:9 or 16:10 form factor that works with new MBP? I could not get my old 30-inch Cinema displays or my relatively new Dell U3014 monitors to work. The Cinema displays do not work at all. The Dells work only with the HDMI cable, but the fonts are broken. I don't really want to purchase new monitors, but it looks like I have to.

@joe Wow, seriously? I have a U3014 and assumed it would just work. Which non-HDMI cable did you use?
