The video card's so-called "resolution" specifies how many dots it is
capable of displaying, vertically and horizontally. It can be changed over a
wide range of settings. But this does not specify the resolution.
(Resolution is specified in dots per inch (or pixels per inch). The video
card only specifies total dots.)
Your monitor's resolution determines what you can actually see. The monitor,
whether CRT or LCD, has a fixed number of active elements (pixels) per inch
(or per millimeter). The number of pixels per inch sets an upper limit on
your display resolution. This usually runs somewhere around 100 dots per
inch.
If your video card is set to display 1024x768, then your 1024 horizontal
pixels are spread across the horizontal width of your monitor. If that width
is, say, 16 inches (typical 21" CRT), then you're seeing 64 dots per inch.
(On a screen twice the size, you'll only get 64 dots per inch!)
If you set the card to 1280x1024, then the 1280 horizontal pixels yield 80
dots per inch.
Crank it up to 1600x1200, and you're getting 100 dots per inch. (A good 21"
CRT can be pushed to about 110 per inch, so 1600x1200 is nearly the most you
can do.)
But these numbers only apply if your monitor's pixel pitch can provide at
least that much resolution. CRTs specs show their dot pitch as millimeters
between pixels. A good CRT might have a dot pitch of about 0.22 mm. That's
115 dots per inch.
