HardwareZone has reviewed ViewSonic VX924 TFT LCD monitor, which is the first 19”  product to boast with grey to grey pixel response time of 4ms (note that usually manufacturers indicate of response time as the total time it takes the pixel to change its state from black to white and to black again). ViewSonic states that its Advanced Overdrive Technology, which is basically a higher voltage stepping to boost pixel responsiveness, and Amplified Impulse Technology, which dynamically controls the amount of overdrive required, allowed the company to improve the response time of its monitors.

“We found that the VX924 to have an excellent panel which was free from image distortions and was able to display very sharp images. This could very well be due to ViewSonic’s Advanced Overdrive and the monitor’s good contrast ratio. Images looked more distinct, therefore giving the impression that they were sharper, better outlined and contrasted.  Colors in general were decently represented. The VX924 managed to render very vibrant backgrounds, though we would have much preferred a livelier tint on human tones. While ViewSonic has kept mum about the monitor’s color capabilities in all documents and specifications we looked at, we are quite confident that it uses a 6-bit panel. During our tests, the monitor exhibited a regular amount of dithering usually attributed to such panels. This doesn't really come as any surprise as the VX924 is designed for gaming and entertainment purposes. While the monitor does perform excellently in these environments, color fidelity was still not high enough for professional graphics authoring,” concludes HardwareZone.
