Whether you’re buying a new monitor or replacing the display on your existing machine, there are a few points to consider. Technology has progressed quite a lot in the recent years giving users a lot more options when it comes to monitors. First it’s important to know if you require a CRT monitor, an LCD or a new HDTV.
CRT – Cathode Ray Tube Monitors
CRT or Cathode Ray Tube Monitors are big and bulky and have been used in conjunction with PCs for many years. They are relatively cheap compared to newer LCD and HDTV monitors, and are compatible with all PCs. Resolution is high quality and can be changed to suit screen size or the users preferences, but as the signal is analog, CRT monitor will not have a DVI port and therefore will not directly support High Definition. If you have an up-to-date graphics card graphics card you may be able to connect your HD cable, satellite box top or HD-DVD to your computer however you will loose quality as the HD signal is converted into analog to be displayed on the CRT.
LCD – Liquid Crystal Displays
LCD or Liquid Crystal Displays were first produced in the US back in 1972; however it took quite a few years before LCD monitors were available on the consumer market. Over the last 10 years Flat Screen LCD monitors have become increasing popular as they save space and have better options for newer digital connections like HDTV, plus they usually have more audio option for home theater style set-ups. LCD monitors can produce crisper images than CRT monitors but they can only do so in their native resolution. Attempting to run LCD panels at non-native resolutions can result blurriness and multiple kinds of HDTV Blur. In general LCD monitors can not truly display as many colors as a CRT. LCD’s can also cause migraines and eyestrain problems due to flicker from fluorescent backlights fed at 50 or 60 Hz however this quite rare.
Plasma Screen Monitors
Plasma Screen Monitors are commonly used for large TV displays. Plasma Displays were introduced around the same time as LCD monitor but due to the nature of the components; they are the most expensive type of display monitors. They produce a much crisper image at a higher resolution than LCD monitors. They also support a wide array of video and audio connections for digital or analog use. The superior brightness, faster response time, greater color spectrum, and wider viewing angle of a plasma monitor makes them one of the most popular forms of display for HDTV, however recent improvements in LCD technology have narrowed the technological gap.

Specifications to consider when choosing between the different types of monitors:
Resolution: This is the amount of pixels that can be displayed horizontally x vertically. A higher resolution means bigger and better quality graphics. Standard and most easily viewed CRT resolutions are usually:
- 15″-800 x 600 / 1,024 x 76817″
- 17″-1,280 x 1,024
- 19″-1,280 x 1024
- 21″-1,600 x 1,200
Plasma technology enables bigger screens and higher resolutions in excess of 1920 x 1080. LCD screens also come in large sizes but will have a native resolution for optimal viewing.
Refresh rate: The refresh rate is the measurement of the number of times per second the screen is redrawn. This measurement is measured in hertz, the faster the refresh rate the better quality the picture.
Dot Pitch: This measurement is found on most monitors. It defines the amount of space (in millimeters) that separates two adjacent pixels that are the same color, the smaller the Dot Pitch, the sharper the image.
HDTV Compatible: If you’re looking for a monitor to incorporate your full home theater then HDTV compatibility is certainly something you should look for.
