Artifacts are not cause by the CRT but rather the NTSC format. The 
rapidly changing pixels appear to the composite demodulators as color 
information as the rate of change has the same frequency as the color 
burst. Difference in phase with the color burst gives the color.

So if the LCD TV has a composite input which conforms to NTSC standards, 
you ought to see artifact effects.
