The fun path would be to modify the display to run at 3Hz (and also implying the much slower horizontal scan rate), but due to the phosphor coating's short persistence, you'd at best see only a small sliver of the full picture at any time. Exactly like you see if you point a video camera to a CRT whose frequency does not match up exactly.
But if you'd take a long exposure photo of the CRT, it would likely work! (EDIT: Might fry your phosphor, though... as for any other components, like filters or components that may get damaged by the now only slowly changing current, I just assume you replaced or retuned that as part of the conversion process.)
- userbinator 3y agoThere are CRTs with long-persistence phosphors too; they found applications in radar and the like: https://en.wikipedia.org/wiki/Phosphor#Standard_phosphor_types https://en.wikipedia.org/wiki/Phosphor#Standard_phosphor_typ... https://tubetime.us/index.php/2015/10/31/crt-phosphor-video/ https://tubetime.us/index.php/2015/10/31/crt-phosphor-video/ http://www.labguysworld.com/crt_phosphor_research.pdf http://www.labguysworld.com/crt_phosphor_research.pdf The P10 phosphor there claims "Persistence from several seconds to several months"(!)
