Comparison of CRT & LCD monitors

Summary

Ultimately, it cannot be said that LCD monitors are superior to CRT monitors or vice-versa either.
Rather when choosing which device to use you need to weigh up the advantages and disadvantages
in order to decide which technology to use.

In the public and presentational arena, LC displays are definitely preferable over CRT monitors. In
relation to the display workstation order, the small footprint is also an important argument and in
this respect more favours flat panel displays. On the other hand, when it comes to particular colour
depth, or you need a large viewable diagonal, the choice of a CRT monitor is still unrivalled.
