LCD VERSUS CRT
One disatvantage LCDs have is having fixed
pixels which makes it more difficult to scale
video than a CRT. A CRT can change the pixel
size by adjusting the size of the beam, LCDs
use a processor called a Scalar. LCDs feature
their best picture quality at their native
resolution (or max res) and CRTs feature good
quality at any resolution up to their maximum
resolution.
