Dot
Pitch
Dot
pitch is the distance between phosphor dots that are alike
in color. These phosphor dots are tiny red, green and blue
phosphors. The image you see on the display is composed of
these tiny phosphors (called triads - a group of one red,
one blue and one green colored phosphor) that produce colored
light patterns. The display creates the illusion of other
colors by lighting these phosphors up in different concentrations.
Dot pitch is sometimes referred to as phosphor pitch. The
image displayed will be more detailed and graphic the more
minute and less distance the dots are to one another. The
image will look grainer when the dots are furtherer apart.

Vertical
Refresh 
Vertical Refresh or Refresh Rate in interlaced* mode this
is the number of fields written to the screen every second.
In non-interlaced mode it is the number of frames (complete
pictures) written to the screen every second. Higher frequencies
reduce flicker, because they light the pixels more frequently,
reducing the dimming that causes flicker.

Resolution
Resolution
is the number of pixels per unit of area. In a monitor, this
is the number of pixels the graphicscard describes the desktop
with expressed as a horizontal and  vertical
figure. A display with a finer grid contains more pixels and
has a higher resolution therefore it is capable of reproducing
more detail in an image. This allows more of an image to be
seen, reducing the need for scrolling or panning. The two
most common resolutions are SVGA (800x600 pixels) and XGA
(1024x768 pixels).
