Monitor Response Time - Is It Really That Important in a Gaming Monitor?

By Kevin Oleary


If you have been shopping for a computer monitor in recent months, you could have recognized a great deal of consideration being given to just one spec specifically: response time. Also known as response rate or maybe latency, an LCD's response time really means that how quickly it is able to display moving images. The majority of previous year's Liquid crystal displays came with 16-millisecond (ms) response times--fast enough for decent-looking Dvd playback, although with a few ghosting along with distortion. But yet response times are falling, and with Samsung and then ViewSonic debuting Lcds by working with 3ms and 4ms response times much earlier this year, Liquid crystal displays would appear to be nearing the performance offered by CRTs. But nonetheless , exactly what do response time numbers definitely really mean?

A quicker response time is undoubtedly better--it indicates how fast your display can refresh a video image. If LCD's response time is actually slow, the display's pixels won't be able to maintain the material sent from your computer's graphics card, and you will see ghosting and digital distractions as a result. But just considering that a vendor promotes a fast response time doesn't mean that the Liquid crystal display will handle moving visuals far better.

Response time is described as the time needed for a good Liquid crystal display pixel to change starting from fully active (black color) to fully inactive (white), and then back to fully active again. A lot of vendors, on the contrary, document their particular LCDs' gray-to-gray response times. Pixels are rarely completely on or even off--instead they period between gray states, that is colors--and, generally, changing between gray states is much less quickly when compared with switching between white and black.

Nevertheless, some also believe that testing gray-to-gray response time is actually pointless, considering that the suppliers almost never inform where in the cycle they begin as well as end their particular measurements. To help remedy this misconceptions, the Video Electronics Standards Association (VESA) intends to introduce a new spec standardizing response time way of measuring sometime in the year 2006.

Today, in spite of this, providers continues to report the "fastest possible" response time, rather than the average and also common response time that you and I would observe in daily usage. And, sometimes manufacturers can't figure out precisely how fast their very own items are, as with ViewSonic's September '05 announcement that its ViewSonic VX924 Lcd actually had a 3ms response rate rather than the recently announced 4ms rate.

In any case, while response time specs can help when shopping for a new monitor for viewing Digital video disks or gaming, we highly recommend testing the display screen yourself before purchasing. CNET does not formally test response times, but we judge game playing as well as Dvd efficiency with our own eyes, and that we suggest that you to do the same.

Here are several displays we have analyzed with relatively quick response times of 8ms or maybe less. Their functionality in different gaming assessments varied substantially.
