With technology progressing as fast as it is at the present, it is a wonder we do not have a new mass-marketed gadget appearing every few minutes. Personal computers, once predicted to be owned by a mere handful of individuals, are everywhere nowadays. If you are a student a personal computer is virtually a necessity. Accompanying the ever-increasing popularity of the personal computer is a plethora of gadgets and technological advancements. Though it may not be every few minutes, it seems as though every couple of months we hear about a computer with more storage space or a new device that one can connect to their computer.

Some devices that appear on the market are either completely superfluous or not so accessible to the entirety of the population, whether it is because of their cost or their limited supply. The costly devices are reserved to those who can afford them, until some new gadget replaces them and the price of these machines decreases, much like any new technology that appears on the market. Those gadgets, which are unnecessary, are not overly practical and the market for these creations is comprised mainly of those with an affinity for such devices. Inventions like webcams, while they are certainly fun to play with, are essentially unnecessary as they have no bearing on the actual operation of the computer and are used largely for leisure computer activities.

The more purposeful advancements in computer technology revolve around those, which increase the computers ability to manage certain tasks and those, which increase the storage space of the computer. Many personal computer owners find themselves craving more space to store songs or various other files and often wishing that their computer were faster. Though many computers produced today have a excessive storage space, that is, it is nearly impossible to fill a personal computer to capacity, these types of advancements permit a much speedier and more efficient functioning computer.

Well Monty! When shopping for a monitor for gaming or multimedia you will see manufactures brag about their response time. Although response rate or latency is extremely important when it comes to games, the manufactures derive this number in various ways.

Generally, manufactures report their fastest time, whether that is gray-to-gray or active black to inactive white and back. They may not disclose which they used to determine their typical time. The formal definition characterizes response time as the time it takes for an LCD pixel to change from completely active black to inactive white then back again. However, manufactures often report their gray-to-gray speed (or color to color). The Video Electronics Standards Association (VESA) will soon introduce specifications to standardize response time to make manufacturers’ numbers more comparable.

Nevertheless, despite the discrepancies over reported numbers, response time does matter. As recent as 2005, monitor manufacturers and gaming experts were recommending a response time of under 16ms to avoid blurring and ghosting. However, a year later we are seeing response times of less than 5ms, or more typically, less than 8ms. This in turn means that game manufacturers are going to utilize these new capabilities and create games that demand this faster response time.

For now, to view your games at their best, look for a monitor with the fastest time possible; it does matter. Keep in mind that display quality is also important, so look for a high contrast ratio and small dot pitch coupled with a powerful graphics card to give you the best view possible.

In technology, response time is the time a system or functional unit takes to react to a given input.
Response time is the amount of time a pixel in an LCD monitor takes to go from black to white and back to black again. It is measured in milliseconds (ms). Lower numbers mean faster transitions and therefore fewer visible image artifacts.

Older monitors with long response times would create a smear or blur pattern around moving objects, making them unacceptable for moving video. Long response times can be annoying to a viewer depending on the type of data being displayed and how rapidly the image is changing or moving. Many current LCDs' monitor models have improved to the point that this is rarely seen.

A figure of 8 to 16 ms for rise + fall times is typical. The response time was traditionally recorded at the full black > white transition which became the ISO standard for this specification on LCDs. Grey transitions are far more common in practice but in terms of pixel latency, they remained significantly behind the ISO transition. In recent years there have been a wide range of Response Time Compensation (RTC) / overdrive technologies[1] introduced which have allowed panel manufacturers to significantly reduce grey transitions. Response times are now commonly quoted in "G2G" (alternately "GTG," meaning: "grey-to-grey"[2]) or "GLRT" (meaning: "Gray Level Response Time"[3]) figures and specs of 6ms, 4ms and 2ms G2G are widely available. There are various names used for RTC technologies, and these vary from one manufacturer to another. Terms such as ClearMotiv (Viewsonic), AMA (BenQ), MagicSpeed (Samsung) and ODC (LG.Philips) are widely used to identify RTC enabled displays.

In comparison, a CRT displaying a picture with an update frequency of 60 to 80 Hz could be said to have a response time of 12.5 ms and upwards. However, as the picture is updated completely (and virtually instantly) each time the electron beam passes over the screen, CRTs do not have the same problems with smearing or ghosting. The same is true for plasma displays (however, both CRTs and plasma displays can have problems with flicker).

LCD screens with a high response time value are often unsuitable to play fast paced computer games. The pixel response time is often confused with the LCD input lag which adds another form of latency to pictures displayed by LCD screens. An LCD screen with high response time and significant input lag will not give satisfactory results when playing fast paced computer games or performing fast high accuracy operations on the screen (e.g. CAD). Manufacturers only state the response time of their displays and do not inform customers of the input lag value.
