COMPUTER MONITORS Technology, Uses & Costs

liquidation is often touch on by and a combined result of bandwidth, sexually transmitted disease frame and the intenses adapter's block. There are deuce-ace types of graphics standards, VGA, XGA and super VGA. All three have a divers(prenominal) resolution value and color capabilities:

Video Graphics wander (VGA) ? 640 x 480 resolution in 16 colors

Extended Graphics Array (XGA) ? 1024 x 768 resolution in 256 colors

Super VGA (SVGA) ? 1280 x 1024 in 16 or 256 colors

The resolution represents the graphic adapter's potential. In early(a) words, a graphic adapter that has a resolution of 1280 x 1024 is able to paint 1280 pixels across the classify and 1024 lines crosswisely. The more pixels that you piece of ass electronically paint on the dissemble, the more you can contact on it. When there are more pixels, they are set up in a tighter spatial arrangement, thus producing sharper and clearer images than graphic adapters with lower resolution capability.

Dot pitch is important for scarcely the reason mentioned above-clarity. The sprinkle pitch measures the distance between separately pixel on the screen. However, the phospors are arranged in groups of three (red, green, and blue) and the dot pitch is the space between phospors of the same color. The littler the distance between pixels, the sharper and clearer the images portrayed on the screen, " normal dot pitches measure from 0.24 mm to 0.51 mm. The smaller the dot pitch, t

Size is also related to resolution. The large the screen the higher the resolution capability. At the highest resolution, screen size is very portentous. Further, when size is being considered, one must dream up that the observe size advertised is often non the exhibit image size on the actual glass screen. For example, the monitoring device size is usually measured diagonally from one box seat of the screen to another. However, this screen measurement is often lower than the size of the advertised monitor. For instance, 15- border monitors typically only have a screen size that is 13.4 to 14.2 inches. Computer monitors range in size from 9 to 39 inches, but the ones that have sold the most during the prehistorical decade have been in the 14 to 17 inch range.

High cost and a lack of sophisticated engineering science were obstacles to selling larger monitors until recently because of new technologies and a significant reduction in price for computer hardware across the spectrum.

he crisper and cleaner the picture" (James 3). A computer monitor with a dot pitch of 0.24 would have a some(prenominal) brighter image than one with a dot pitch of 0.51. The dot pitch you need is directly related to the size of the screen you want. Smaller screens typically require a smaller dot pitch.

The refresh rate is significant, because, as mentioned earlier, if the refresh rate is not high enough there will be an galling flicker on the computer monitor. This is because the electronic paint gasolene is not able to spray electrons quickly enough to keep the screen image from fading somewhat before it is replenished. The yearner it takes to draw the lines on the screen, the longer is the refresh rate. The horizontal gulp and vertical drawing are measured in different units, "The horizontal scan rate (also called the line scan rate, the horizontal frequency, vertical refresh rate, or simply refresh rate) is a measure of how many horizontal lines it dr
