If you are looking for a new display, you should consider the differences between CRT and LCD monitors. 1. _______________________________________________________________

Advantages of LCD Monitors
- Require less power: power consumption varies greatly with different technologies. CRT displays are somewhat power-hungry, at about 100 watts for a typical 19-inch display. The average is about 45 watts for a 19-inch LCD display. LCDs also produce less heat.
- Smaller and weigh less: an LCD monitor is significantly thinner and lighter than a CRT monitor, typically weighing less than half as much. In addition, you can mount an LCD on an arm or a wall, which also takes up less desktop space.
- More adjustable: LCD displays are much more adjustable than CRT displays. With LCDs, you can adjust the tilt, height, swivel, and orientation from horizontal to vertical mode. As noted previously, you can also mount them on the wall or on an arm.
- Less eye strain: because LCD displays turn each pixel off individually, they do not produce a flicker like CRT displays do. 2. __________________________________________________

Advantages of CRT Monitors
- Less expensive: although LCD monitor prices have decreased, comparable CRT displays still cost less.
- Better color representation: CRT displays have historically represented colors and different gradations of color more accurately than LCD displays. 3. _______________________________

- More responsive: historically, CRT monitors have had fewer problems with ghosting and blurring because they redrew the screen image faster than LCD monitors. Again, LCD manufacturers are improving on this with displays that have faster response times than they did in the past.
- Multiple resolution: if you need to change your display's resolution for different applications, you are better off with a CRT monitor because LCD monitors don't handle multiple resolutions as well.
- More rugged: although they are bigger and heavier than LCD displays, CRT displays are also less fragile and harder to damage.
So now that you know about LCD and CRT monitors, let's talk about how you can use two monitors at once. They say, "Two heads are better than one." Maybe the same is true of monitors!

Dual Monitors
One way to expand your computer's display is to add a second monitor. 4. _______________
_____________________________________________________________________________
With two monitors, you can:
- View large spreadsheets;
- Make changes to a web page's code on one monitor and view the results on the second;
- Open two different applications, such as a Word document on one monitor and your web browser on the second.
Besides two displays and two sets of the appropriate video cables, the only other thing you need is a video adapter with two display connections. The connections can be analog or digital; they need only to match the type of connections on the monitors. It does not matter what type of monitor you use; two LCDs, two CRTs, or one of each works fine as long as the video adapter has compatible connections.
If you don't have a video adapter with two connections, you can purchase one and replace your current adapter. This generally works better than simply installing another video card with a single connection. Combination cards also come with more features, such as a TV-out port.
In addition to verifying your hardware, you should also double-check your computer's operating system to be sure it supports the use of dual monitors. For example, Windows 98 SE, Me, 2000, and XP support multiple monitors.
If you really want to increase your screen real estate, especially for applications such as financial trading or 3-D design, you can even implement three or more monitors.
Other technologies include:
Touch-screen Monitors
Displays with touch-screen technology let you input information or navigate applications by touching the surface of the display. 5. _______________________________________________

Wireless Monitors
Similar in looks to a tablet PC, wireless monitors use technology such as 802.11b/g to connect to your computer without a cable. Most include buttons and controls for mousing and web surfing, and some also include keyboards. The displays are battery-powered and relatively lightweight. Most also include touch-screen capabilities.

Television and HDTV Integration
Some displays have built-in television tuners that you can use for viewing cable TV on your computer. You can also find displays that accept S-video input directly from a video device. Additional features include picture-in-picture or picture-on-picture capability, a remote control and support for high-definition television (HDTV).
A. However, LCD displays are gaining ground in this area, especially with higher-end models
that include color-calibration technology.
B. The technology can be implemented through a variety of methods, including infrared sensors,
pressure-sensitive resistors or electronic capacitors.
C. This limitation derives from the fact that most touch-screen displays today use a single sheet
of glass as the top layer.
D. Choose the type of monitor that best serves your specific needs, the typical applications you
use, and your budget.
E. Using dual monitors can make you more productive and add a lot to your computing
experience.
F. In addition, LCD displays do a better job of displaying text compared with CRT displays.
