Monitor (Computer Display)

Important Factors for Selecting Monitor:

 

1- CRT or LCD

2- Size  (15 inch - 21 inch)

 

A larger monitor is important for business and power users, plus anyone who wants a more comfortable viewing experience. A larger monitor means:
 
  •  No squinting
     
  • Less scrolling
     
  • More room to view windows, palettes and multiple documents
     
In addition, larger monitors are linked to increased productivity. Research suggests that an employee may reclaim more than 17 hours per month working on a larger screen.* Replacing 15" monitors with 19" monitors may actually earn back 204 hours of work annually for each employee. For businesses (large and small) choosing 19" monitors, the monitors may pay for themselves in just a few months.

Keep in mind that seemingly small increases in diagonal screen measurements mean significant increases in screen area: A 17" monitor has almost 30% more viewable area than a 15" monitor, and the viewable area of a 19" monitor is 25% larger than a 17".
 

 

3- Native resolution (Upto 1280 by 1024 pixel)

4- Aspect ratio

    Most LCDs have a screen aspect ratio of about 4:3, much like a regular-format TV. However, wide-screen monitors have an aspect ratio closer to the 16:9 aspect ratio of HDTVs.

 

 

5- Viewing angle (Measured in degrees)

6- Flat screen (Only for CRT)

A flat panel  monitor  may be either a plasma or LCD . These Monitors have wide screens, but are also very thin (a few inches) and have the ability to be hung on the wall like a painting. On the other hand, a flat screen monitor may not be thin at all and may appear more bulky like traditional monitor. It simply has a flat screen across the front of it so viewing angle is no longer reduced by tube curvature. Also, anyone who can see the screen will be able to see the entire picture, and the flat screen eliminates unwanted reflection.

7- the p and i stand for after the format numbers

The p and i stand for progressive or interlaced which refers to the scanning system. In an interlaced format, the screen shows every odd line at one scan of the screen, and then follows that up with the even lines in a second scan. Since there are 30 frames shown per second, the screen shows one half of the frame every sixtieth of a second. For smaller screens, this is less noticeable. As screens get larger, the problem with interlacing is flicker. Progressive scanning shows the whole picture, every line in one showing, every sixtieth of a second. This provides for a much smoother picture.

8- Contrast ratio

This term refers to the difference in light intensity between the brightest white and the darkest black that an LCD can produce. Look for a contrast ratio of 400:1 or better--with anything lower, colors may wash out when you turn up the brightness and may disappear when you turn it down.

9- Brightness
Expressed as candelas per square meter (cd/m2) or nits, this specification measures the greatest amount of light that comes from a screen displaying pure white. Nearly all LCDs have a brightness level of 250cd/m2 or greater, which should be more than sufficient. (In comparison, CRT monitors typically average about 100 cd/m2--though you might see some high-brightness CRTs.)

10- Digital versus analog

 If you have a graphics card with digital video-out--and if your computer is less than two years old, you probably do--choose an LCD that has DVI digital input. The image won't have to convert from analog to digital and back again, so it will be clearer.

11- TV Tuner

12- Dot Pitch

The distance between dots of the same color (red, green, or blue) on the screen. The smaller the dot pitch, the crisper the image. Standard is .24mm horizontal dot pitch. 

13- Primary Use
The setting in which you'll use your monitor is an important factor in selecting the right monitor. Will you be using it in your home office? Are you purchasing multiple monitors for an enterprise solution? For an education setting?

ViewSonic's Product Finder lets you identify your primary use from among the following categories:
 
Top reasons to choose LCD:

Sleek, space-saving design. LCDs use as much as 75% less desk space than CRTs (and can be wall-mounted, too).

Ergonomic features. A brighter, flicker-free screen with perfect geometry and virtually no glare reduces eye strain.

Better total cost of ownership. LCDs have twice the lifespan, one-third the electricity usage and minimal heat output compared to similar-sized CRT monitors.

Safety. LCDs are safer to use because they have no electromagnetic radiation.

Price. LCDs are more affordable than ever.

Top reasons to choose CRT:

Excellent value. CRTs have become very inexpensive for entry-level models, and high-end full-featured displays are now more affordable than ever.

True-to-life color. CRTs provide a rich, full spectrum of brilliant hues and precise color fidelity.

Vibrant, realistic images-even in motion. The full spectrum of saturated colors with incredible depth and superior video response makes CRTs perfect for gaming, graphic design or even watching TV.
