A television set, displaying a television signal is analog.  A computer    
monitor, displaying a computer image is digital.  The best way to 
approximate the TV's analog picture, is with a larger range of discrete colors.
Obviously, painting a 2D image with 16 million colors is overkill, but to 
render 3D images, 24-bit color is still not overkill.  The reason a television
doesn't have those awful aliasing lines, is because the dithering is inherent
in the generation of the image.  To get an equivilent picture we would need
analog rastor images, but that's not how a computer likes to remember things
(remember our image is always stored digitally unless its on tape.)  This means
that no matter how many colors the eye can detect, (I have normal vision and 
can barely tell the difference between HAM colors) the creation of lifelike, 
non-surrealistic images depends on huge amounts of colors.
