Sony made a portable 1920x720 laser projector. Kicking myself for not getting it just for fun. . That’s the only consumer model I’m aware of. It had four diodes: 1 red, 1 green and 2 blue. Was rated for 2000 hours of useful laser diode life.Oh, interesting find. I can't see any price for current models and it probably costs a kidney or two given the giant display surface, but the technology is definitively interesting.
