Ok, I'll look into it, read your guide for a start, thanks.

It is a CRT projector. It behaves differently to a digital. It can do peak white very well, but not a full white field.

Colorfacts can measure with a small field, rather than a full screen (like the HCFR inbuilt stuff). A field suits a CRT projector better.

Subjectively it's as bright as most HT dedicated digital projectors.



As for the 20% being low, again that's a CRT thing. Some people put a bump in their gamma curve to address this, but I found that causes streaking (another CRT thing) on mine.

I can raise the brightness, which will lift 20%, but then black won't be BLACK. I've never seen a digital where black is completely black, always grey.

I can choose to crush a bit of the low end, and have BLACK blacks, or slightly lit blacks (like a digital) and better shadow detail. At least I have a choice
