With LCD monitors and screens, resolution
generally is proportional to the size of
the device. For example, a widescreen 19-inch
LCD monitor typically has a resolu tion of 1440
3 900, while a widescreen 22-inch LCD monitor
has a resolution of 1680 3 1050. LCDs are
geared for a specific resolution, called the native
resolution. Although you can change the resolution
to any setting, for optimal results, use the
monitor’s native resolution setting.
With game consoles, such as Microsoft’s Xbox
360, Nintendo’s Wii, and Sony’s PlayStation 3,
the output device often is a television.
Users plug one end of a cable in the game
console and the other end in the video port on
the television. Home users often prefer the larger
television displays for game playing, watching
movies, and browsing the Internet on a television
connected to a game console.

printers create images that are of
applications requiring high image quality, such
as photography studios, medical labs, and security
identification systems, use dye-sublimation
printers. These high-end printers cost thousands
of dollars and print images in a wide
range of sizes. Most dye-sublimation printers
for the home or small business user, by contrast,
typically print images in only one or two sizes
and are much slower than their professional
counterparts. These lower-end dye-sublimation
printers are comparable in cost to a photo
printer based on ink-jet technology. Some are
small enough for the mobile user to carry the
printer in a briefcase.
Audio resolution, which is the number of bytes
that represent sound in a given time, is stated as
a bit rate such as 8-bit, 16-bit, or 24-bit. A sound
card using 8-bit resolution, for example, represents
a sound with any 1 of 256 values (28), and a
16-bit sound card uses any 1 of 65,536 values (216).
Higher resolutions result in better sound quality.
With 8-bit resolution, the sound quality is similar
to an AM radio; 16-bit resolution yields optical
disc-quality sound; and 24-bit resolution is used
for high-quality digital audio editing.
