All depends on how they are spec'ing it. 16ms G-G is pretty pathetic by even modern IPS standards, but 16ms B-B isn't too shabby. That's pretty typical for a good H-IPS type with proper overdrive like the NEC 2490WUXi which specifies 16ms B-B and 8ms G-G. Of course, there's all sorts of G-G specifications, too, which is often how those silly 2ms type numbers are pulled out of various orifaces. TN and VA type panels do tend to have better response times than IPS, though sometimes there are processing delays (latency - see below) to achieve those response times. However, they sacrifice color gamut and viewing angle to do it. Color gamut is probably not a concern for you, but viewing angle probably is. Most TN displays will start to at least dim and usually color shift when viewed off-angle by as little as 10-15 degrees in either direction. VA type panels do OK horizontally, but usually have the same problem with vertical off-angle viewing as TN. S-IPS is by far the best technology out there, but H-IPS represents little compromise and gets you notably better response times. Unfortunately, IPS panels are hard to come by these days due to cost pressure: IPS panels cost a lot. That 24" NEC monitor retails for ~$1000. As several have pointed out, response time != display latency ("lag"). Response time is the time during which the pixel is "in transition" before it arrives at its commanded state. This effectively looks like a blur effect. Latency is (usually) caused by digital scaler chains, and just results in a video stream that is delayed. PC monitors rarely exhibit notable latency (cheap monitors are usually at worst a frame or two), but all LCDs have response time. I consider ANY measureable latency (greater than one frame) unacceptable in a monitor application, but I'll take at most 1 frame on a TV if I don't have serious gaming intent (I just returned a TV with such latency though - it lagged too much for some of my games). It is noticeable on games like beatmaniaIIDX and pop'n music which involve very precise timing, even tigher than some fighters. |

Microseconds I'd say maybe... but still think response rate is faster than that. That is... if you're even talking about pixel response rate. 50 Microseconds would put it faster than any LCD out there. For reference, my Samsung LED DLP has a pixel response time of 16MICROsecond response time... putting it at .016 Millisecond refresh. --- Quote ---In contrast to LCD displays, plasma televisions and CRT TVs have a virtually instantaneous response time. http://www.practical-home-theater-guide.com/lcd-response-time.html --- End quote --- Also, go for 8millisecond or lower pixel response time when shopping for an LCD as already mentioned above, as a general rule of thumb. --- Quote ---Our experience show that even with some 8msec LCD display panels, the discerning eye may still be able to detect a slight 'trailer' or blurring effect, where the individual pixels on the LCD display appear to be just out of step with the image on the screen during very fast sports events and action movie scenes. http://www.practical-home-theater-guide.com/lcd-response-time.html --- End quote --- |
