The Monitor

The VX1940w is not the best looking monitor from Viewsonic, but its simple matte black and silver finish do make it look quite smart. It measures 17.4x15.1x7.7 inches (with the stand).

It has a 16.1x10 inch (19-inch diagonal) viewing area that has a maximum resolution of 1680x1050 pixels (max); that's as many pixels as a 22-incher can support. The panel surface is anti-glare type and has a 40,000 hour rated lifetime for the light source. It has a maximum brightness of 300 cd/m2 and contrast ratios are 1000:1 (static) and 3000:1 (dynamic), respectively. The response time is 2 ms for gray-to-gray and 5ms for black-white-black transitions.

The monitor has a DVI-D connector as well as a VGA (D-Sub) connector for input. It operates at a frequency of 24-82 kHz (horizontal) and 50-85 Hz (vertical), respectively.

It also uses Amplified Impulse technology to deliver better picture quality. Let's see what it's all about.

The 2ms response time that the VX1940w delivers is large due to the use of this new Amplified Impulse Technology.

Amplified Impulse Technology is an intelligent overdrive technique that works by applying a "full-white" drive signal to a pixel for a brief duration, in order to give them a "jump-start".

Amplified Impulse Technology allows gray-to-gray transitions to be completed up to 12 times faster than typical "fast-response" LCD displays. With no tradeoffs other than manufacturing cost, Amplified Impulse Technology provides for a dramatic improvement in gray-to-gray response time and motion video performance.

The image below shows how Amplified Impulse uses variable signal modulation to accelerate grayscale transitions for superior motion video and gaming. The dotted lines represent an idealized response, the black lines represent the response from a traditional LCD, and the red lines represent the expected improvement from Amplified Impulse Technology.
