The CRT's display works by scanning an electron beam across the screen
of colored phosphor dots. It has its limits too, in the spacing of the
phosphor dots and, usually more significantly, the tightness of the
beam, but it is able to vary the spacing of the scans. Dots that are
half-hit or grazed mostly glow only, I believe, where they are hit.
On an LCD the "scan line" equivalents are fixed. Displaying, for
example, a 2048x1536 display mode on a native 1024x768 LCD is more
like making a comparable reduction in an image file. Pixels will be
combined and averaged, effectively giving you the lower-resolution
display while still using all the video memory & processor time of the
higher resolution.
