Question Projections fading when far from camera

Hi everyone, this is my first time on the Unity forums and I'm very much a newbie but I'm having some trouble with a projector.
It works just fine, I've copied and pasted an additive tint shader that I'm using on the material for the projector to project a green reticle onto the ground. However, when I move the projector far away from the camera there seem to be lines it crosses where the projected image becomes worse in quality until it eventually disappears.
I assume this is some automatic culling issue but I honestly have no idea.

I've attached a video of the problem. Thanks for any help :^)

 

Looks like a texture mip mapping problem.

Try setting the Aniso Level on the texture to 16.
