A positive trend in the computer market is the declining prices of the Liquid Crystal Display Monitors. There was a time when the LCD monitors were used only in the portable computers. They were considered expensive and invariably used in the sophisticated units like notebooks. Now that the high quality product is offered at lower rates and that too with special features by prominent manufacturers, it has become affordable to even low end users. Many of the latest introductions in the market are with DVI and HDMI inputs. They are light weight and sleek. Further the LCD monitors consume less power than the CRT counterparts.
LCD monitors are available in different sizes from 19 inches to 24 inches and also wide screen category for gaming. 19 inches flat panel displays are also available for basic users. The shoppers should know that the screen dimensions mentioned in the case of LCD monitors are the actual size (diagonal). It will be difficult for the ordinary computer user, who is not very much conversant with the technical jargon to understand the significance of the various standards and dimensions mentioned in the product information brochures. It is therefore better to consult friends or reliable dealers before buying a LCD monitor.
Apart from screen dimension and aspect ratio, there are other factors like Native Resolution, Contrast Ratio, Viewing angles and Response time which are important while choosing LCD monitor. To put it vaguely, Aspect Ratio represents the vertical and horizontal measurement. It will be similar to television screen and in most cases will have 4:3 ratios. The LCD screens display only in a single resolution technically called Native Resolution. Actually it is the number of horizontal and vertical pixels that constitutes LCD matrix. Contrast ratio is an indicator of the differences in the density of light and dark presentations on the screen. Viewing angle represents the preferred position of the viewer. Generally 180 degree is the most ideal viewing angle, but at least 160 degrees will be comfortable. Another factor is the Response time which is the time taken for images to appear through the crystals.
If the consumer is contemplating on replacing the existing monitor with the LCD, it is essential to verify whether it is compatible with the system. The type of connector makes the difference, which is to be ascertained. Make sure whether the connector can be used with the existing video card. Alternatively find out what type of connector will be suitable for the video card.
The consumer can obtain valuable information from the internet in this regard. However it is better to visit a computer dealer and personally verify the various factors mentioned above. A reliable dealer will be able to guide the customer with necessary information. It is needless to state that LCD monitor is an expensive component of the computer and therefore it is necessary to exercise caution. The credibility of the dealer, return policy, discount offers, warranty and above all after sale service are to be considered before finalizing the purchase.
