A-TW Polarizer

The NEC 2490WUXi was born with a A-TW (Advanced True Wide) Polarizer - a unique feature that cannot be underestimated.
This feature prevents LCD glow from angle view. It keeps colors, especially black, stable.
This quality is never reflected in traditional picture quality measurements (brightness, color accuracy, contrast ratio, etc.). This quality is not measurable but it's invaluable.
A-TW Polarizer makes NEC 2490/2690WUXi a class of their own.

2490 owners can observe some very light color tint on a pure black screen in darkness from exreme angles: greenish from the left and dark purple from the right - both not visible in real applications. Is it bad? No. It's great. It indicates A-TW polarizer.

What does A-TW polarizer do in practice?
You'll the video in a moment.
