Get a CRT.

Crt shaders is the television equivalent to transsexualism.
you can dress your HDTV/monitor however you like, you can call it whatever you like, you can pretend it's just like a real CRT, you can have your little communities where you affirm each other and exchange pleasantries, but it's still not a CRT, it'll never be like a CRT and it's just plain ugly to everyone outside your fantasy bubble.
