VA (Vertical Alignment) panels are the middle option in LCD panels. They were originally designed to offer better color reproduction and wider viewing angles (up to 178-degrees) than TN displays, and faster response than IPS. Their main strength is in better blacks and higher contrast ratios compared to other display types. This makes VA panels good for video playback and movie watching.
However, because of the way VA panels are designed, they have an inherent flaw that’s known as color shifting. Color shifting is when an image viewed from different angles appears to change position when view from another angle, due to uneven brightness levels. The color shifting also has another side effect in that shadow details are lost in dark scenes, especially when viewed from the center.
Also, while other display types (TN and IPS) have progressed to address their initial flaws, VA panels haven’t really been able to keep up. Primarily, it’s one of the slower panels around, with average response times in the ballpark of 8-16ms. Who is it for: VA panels were originally the choice for those who wanted a better multimedia experience since it produced greater blacks, which is good for movies. It is also considered an upgrade over TN panels for most general tasks except gaming. However, as both TN and IPS technologies have caught up, many companies have reduced support for VA-type panels.
The BenQ XR3501 is an example of a VA display.
