Which among the following is not merit (advantage) of the Cathode Ray Tube?
It runs at highest pixel ratio
It is less expensive than any other display technology
It is very large, heavy and bulgy
None of the above
Correct Answer :
C. It is very large, heavy and bulgy
Being large, heavy, and bulgy cannot be taken as an advantage of the cathode ray tube. Other displays technologies are available now which are light weighted, flat, and much more advanced.
