DVI out allows you to connect to a monitor that has a DVI socket. Low
end LCD's are SVGA, higher end ones usually accept both.

DVI out means you can connect to an LCD with a DVI socket.
Analog LCDs do not use DVI.

The cheaper LCD monitors use an analog (VGA) connection from the video card.
The better LCD monitors use a digital (DVI) connection from the video card.
The digital connections give a better quality image on the LCD screen. A few
LCD models contain both types of connectors so you have your choice.

First of all, on almost all video cards with dvi ouputs, it's a DVI-I
output. That means that the card actually has both DVI and analog VGA
outputs, all on a single connector. Those cards can generally work with
any monitor using either a vga or DVI connection.
Most CRT monitors and many lcd monitors have analog VGA inputs.
Higher-end lcd monitors have dvi inputs. It's conceptually possible for
a CRT monitor to have a dvi input, dvi is not inherintly LCD specific,
but I'm not aware of any crt monitors that do, and even if some do, it's
very rare.
Almost all monitors that have dvi inputs have dual dvi and analog
inputs. There are very few "DVI only" displays.
Where both input types are available, always use DVI, it will produce a
higher quality image (the extent of the difference is variable, and in
some cases may be essentially zero, but the DVI connection should never
be inferior to the analog input and will usually be somewhat to
substantially superior).
You may occasionally run into older digital LCD monitors that use
previous digital interfaces, in particular "P&D" ("plug and display",
used primarily by IBM) and "DFP" (digital flat panel, used by Gateway,
Compaq and Princeton, as well as others). These older, earlier digital
display stanards are largely subsets of the current DVI standard with
different connectors. There are adapters available that will convert
these older inputs to take DVI cables. However, because of differences
in the DDC signals (Display Data Channel), this conversion will not work
with all combinations of monitors and video cards. Indeed when using
such a cable to connect, for example, a Gateway FPD1500 to an ATI Radeon
video card, one finds that whether or not it works ends up depending on
the firmware revision of the internal converter board in the Gateway
monitor and, interesting, the earlier monitors work, the later ones
often do not.

Hi, Billy.
Have you ever tried to plug your toaster into a phone jack? It won't go, of
course, because the electrical plug and the phone jack are quite different
shapes. (Let's not even think about what might happen if you could plug it
in!)
If you look at the physical shape of the connector on the end of the
monitor's cord, then compare it to the physical connectors on the video
card, you should be able to see whether they will actually plug together at
all.
If you can't get to a computer store to actually SEE both a monitor and a
video card, then you'll have to rely on literature describing them, I guess.
Or simply compare the plug at the end of the monitor's cable with the plug
on the CRT you are using now. As others have said, SOME video cards have
BOTH jacks; some monitors have BOTH plugs.
Someone here should be able to point us to a web page that shows pictures of
the analog and DVI plugs and jacks so that you can see the physical
differences. Until someone posts a better one, have a look at this:
http://www.dvdo.com/faq/faq_cables.html
If your (LCD or CRT) monitor's cord has a plug on the end that will
physically plug into the connector on the backplane bracket of your video
card, then the monitor almost certainly will work with that card if you have
the right driver for the card.
