I am sensitive to flicker, and I can spot a DLP projector from a mile away when it’s a mostly dark background with a few bright objects, as the famous rainbow effect. --- End quote --- That's exactly why it has not caught on. I'm not sure why so far, nobody has tried that in a device that's primarily monochrome with colors mostly just for minor things like accents, for example, an ebook reader. (The tablet tried to be a normal tablet with "eink mode".) |

I haven't looked at the state of the art, but B&W CRTs were very common for medical imaging like ultrasound, they provide a sharper more detailed display than color CRTs and the same is likely true for LCDs. Back in the day at least TV studios also used B&W monitors alongside color because they tend to show more detail and make some types of flaws in the image more visible. |

Eizo makes a bunch of them for medical applications. Prices are in the 4-5 figure range. |

You could say a 4K lcd actually has 12K horizontal pixels whereas a monochrome one would only have 4K. Wouldn’t the colour one give better resolution if it used sub pixel rendering? |
| james_s:
Perhaps? But maybe the color filters would result in a less clear image? There must be a reason these things exist. |
