My projector only supports limited RGB color. That means it expects all RGB values to be in the range of 16–235.

macOS High Sierra appears to be outputting full RGB (0–255) color to my projector. This means the darkest blacks and highest whites get crushed, and the detail lost.

How can I make macOS output limited RGB color, instead of full?

  • @IconDaemon Thanks, but that won't do anything in my situation. It's intended for force macOS to output RGB instead of YCBCR. My Mac is already outputting RGB, but it's RGB full instead of RGB limited. (I tried it last night anyway—it's super easy if SIP is turned off—and it predictably had no effect.) – Wowfunhappy Apr 29 at 19:55
  • I am responsible for > 100 projectors (mostly Epson) and have never experienced this problem. Maybe a new projector is warranted? There's nothing you can set on the projector itself? BTW/ what are you using to connect to the projector? HDMI, VGA, MiniDisplay Port? – IconDaemon Apr 29 at 20:25
  • @IconDaemon Connected via HDMI. I semi-lied in the question for the sake of simplification—I technically can set the projector to full RGB, but then all my other sources which are set to limited RGB will look wrong, and going into the projector's menu to change the setting every time is a major PITA. These other sources include old-ish game consoles (like the Wii U) that simply don't support full RGB, so limited is the standard I need everything to output. – Wowfunhappy Apr 29 at 21:21
  • @IconDaemon BTW, this isn't necessarily a problem you'd notice if you're not (A) watching movies and (B) looking for it. I basically discovered last night that I've had this misconfigured for the past year. – Wowfunhappy Apr 29 at 21:25
