Give your PC a monitor makeover

Aim for a rate of 75 Hz for a monitor up to 17 inches in size and 85 Hz for any larger monitor.

Another consideration for CRTs is dot pitch. The smallerrepparttar dot pitch,repparttar 149667 sharperrepparttar 149668 image. Opt for a dot pitch of 0.26 mm or smaller.

CRTs function very well at multiple resolutions, can display detailed graphics and can be viewed comfortably from wider angles.

*LCD screens*

One ofrepparttar 149669 primary disadvantages of LCDs when compared to CRTs is their limited viewing angle. When viewing a LCD straight on, it looks great. Butrepparttar 149670 screen will appear washed-out if you move your head over torepparttar 149671 side and look at it from a wider angle.

Also, LCDs are optimised to perform at a single resolution. Low-end LCDs have viewing angles of only 100 degrees, which won't give everyone crowded round your desk a clear view.

For a standard 15-inch LCD, try to get a 140 degree viewing angle. Increase that by 20-40 degrees when shopping for an 18-inch LCD.

The brightness of LCD monitors is an important factor. LCD monitors have several backlights that provide illumination. The backlights in a LCD are good for 10,000 to 50,000 hours of operation. Ensure thatrepparttar 149672 backlights come with at least a one-year warranty. Messenger:

*Making a choice*

LCD screens generally cause lesser strain to eyes than CRT monitors.

CRTs have better graphics, but they tend to occupy five times as much space.

If you are a gaming freak, then a CRT is a better option as it is best for any graphic interface.

If you wantrepparttar 149673 sleek look, an LCD is meant for you. It is widely used in banks and treasury and trading rooms.
