From my somewhat limited background in laser technology...The color issues could be overcome. The big issue is controlling the beam. Getting the beams to pass the screen over 15,000 times a second (just to start with) is dificult. The trick with tubes is that relitively simple magnetics can redirect a beam of electrons before it hits the phosphor. With lasers, you have a raw light source. Ever try bending light with amagnet? Redirecting a beam of light is easy with mirrors, but not at the scan rates required for video display.
I've been trying to dream up a way to do it for years.
