[game_preservation] Fwd: End of the arcade CRT monitor

[Martin Goldberg]

We need to clarify the terminology here - you guys are talking more
about video monitors than CRTs in general. CRT != video, a CRT can be
either an XY or a raster (video) display, and both use very different
display technology. Scanlines and the artificating you're talking
about refers to raster/video displays.

Scanlines, artifacting and the like are already simulated in emulators
like MAME and various computer and console emulators. Simulation those
effects are always decent but never the same as the real thing.

And while video CRTs may eventually be scarce (they're nowhere near
that right now), XY or vector monitors are currently very scarce.
