dot pitch

[′dät ‚pich]
(graphic arts)
The width of a dot in a dot matrix.

dot pitch

(hardware)
The distance between a dot and the closest dot of the same colour (red, green or blue) on a color CRT. Dot pitch is typically from 0.28 to 0.51 mm but large presentation monitors may go up to 1.0 mm. The smaller the dot pitch, the crisper the image, 0.31 or less provides a sharp image, especially when displaying text.

Dot pitch measurements between conventional tubes and Sony's Trinitron tubes are roughly, but not exactly comparable. Sony's CRTs use vertical stripes, not dots, and its measurement is the distance between stripes, not the diagonal distance between dots.

dot pitch

The distance between a red (or green or blue) dot and the closest red (or green or blue) dot on a color monitor. Also known as "pixel pitch." The smaller the dot pitch, measured in fractions of millimeters, the crisper the image. For example, a .28 dot pitch means dots are 28/100ths of a millimeter apart. A dot pitch of .31 or less provides a sharp image, especially on text.

On CRTs, the dot pitch is typically from .28 to .51mm, while large presentation monitors may go up to 1mm. On LCD monitors, dot pitch is typically from .16 to .29mm. On microdisplay-based rear-projection TVs, the dot pitch may measure the microdisplay's pixels, not the pixels on the viewer's screen. Thus, an 8µm rear-projection dot pitch is not 30 times smaller than a .24mm (240µm) dot pitch on a CRT or flat panel display, because 8µm refers to the source pixel, while .24mm is the screen pixel (what you see). See rear-projection TV and slot pitch.

No, it does not work the same, since for CRTs, you can have different dot pitches on the same size monitor.
I will discuss these upgrades in a future article, but basically you are looking for a better video card, more video RAM, an enhanced sound card, a larger monitor, or a monitor with a lower dot pitch rating.
It features an impressive 400:1 contrast ratio, a 0.279 mm dot pitch and two built-in stereo 3-Watt speakers.
The GDO 18 TFT LCD provides 235 nits of brightness with SXGA resolution of 1280 x 1024 pixels, 16 M colors, 0.281 dot pitch, and an optional resistive touchscreen.
The displays utilizing Ultra Fine Dot pitches ranging from 0.27" down to 0.26 inch for the CRT models and 0.27-0.297 dot pitch on the LCD models.
The CRT screen is 277 mm wide and has a 0.28 mm dot pitch (i.e., the screen image consists of a series of dots placed 0.28 mm apart).
Dot pitch is said to be 36 percent finer than that of conventional TVs, and the built-in VGA compatibility provides immediate hookup to DOS-based computers.
So, if your tasks include graphics applications, you'll want a monitor that has a higher resolution, generally with a dot pitch of .28mm or smaller.
"Dot pitch" is the distance between the dots on the screen (.33, .28, or .25); smaller is better.
It features desirable image quality with .299 mm dot pitch, 225 nits luminance and a contrast ratio of 500:1, providing exceptional resolution with a 176[degrees] viewing angle.
