Greg,
You are confusing two sorts of "pixels".
When I worked on CAD graphics drivers a few years ago I
added anti-aliassing into the lines drawn into the video ram, where a pixel is (usually these days) 3 bytes or 24 bits.
That is software antialiassing.
But that signal gets transformed from a digital list of
values in a scanline into an analog signal which gets
transferred to the outpt of your video card.
At the other end of the (analog) black cable connecting
your computer to the video card is a CRT or an LCD.
What happens there depends on the physical "pixels" which make up the actual physical stuff which emits
light.
In CRTs it is a glowing phosphor.
In LCDs it is a semi-conductor.
Either way they are arranged in an array of pixels
which may or may not correspond to pixels of the
video card. But the signal which arrives there is
analog, and remains analog in CRTs and gets changed
into digital in LCDs.
Problems occur because what was a wonderful high
quality analog signal for CRTs, may not match up
so well with LCDs.
Mismatches between the two sorts of pixels is what
causes problems:
bits in memory
vs
physical light emmitting matter on the display surface.
Whatever montor you buy you need to test it well
with the application you’d like to use.
