Monitors are your visual link to the
computer. The single most important thing you can do to make
your computing experience more comfortable is to buy a decent
monitor. Monitors run at various resolutions and refresh rates.
640x480 is the default resolution for the Windows operating
systems (this is a low resolution where objects appear large
and blocky). 640x480 just means that 640 pixels are fit across
the top of your monitor and 480 up and down. Most users prefer
higher resolutions such as 800x600 or 1024x768 all the way
up to 1600x1200 (and higher for graphics professionals). The
higher resolutions make objects smaller, but clearer (because
more pixels are fit in the screen). You can fit more objects
on a screen when it is in a higher resolution. Larger monitors
are better for running at the higher resolutions. If you run
a high resolution on a small monitor, the text may be hard
to read because of its small size, despite the clarity. The
refresh rate is how fast the monitor can refresh (redraw)
the images on the screen. The faster it can do this, the smoother
your picture will be and the less "flicker" you will see.
Monitor resolution is measured in terms
of dot pitch. The smaller the dot pitch, the higher the resolution.
The smallest acceptable dot pitch for a 17 inch monitor is
.28.
Try to get at least a 17 inch monitor.
At this point that is the standard for most computer users.
If space or money is an issue than go for a "15 monitor.
If you plan on using your computer to watch DVD movies or
to play action games you might want to spend a bit more and
go for a "19 or higher monitor or even larger if you
can afford it.
