Acer p191w vs ViewSonic VP2770 LED: 20 facts in comparison

1. response time

Response time is how long it takes for a display to change the state of pixels, in order to show new content. The less time it takes to respond, the less likely it is to blur fast-changing images.

2. every pixel has three subpixels

The device has a display with three full subpixels per pixel, resulting in a sharp and crisp picture. Pixels in some displays (like AMOLED) share one subpixel to preserve space. This can result in a less crisp, slightly blurred image.
