Superior Contrast and Black Levels:
The vertical alignment of the liquid crystals gives VA panels their deep blacks and excellent contrast ratios. This makes them great for dark-room viewing, movies, and content where high contrast is needed.
Better Viewing Angles than TN:
Compared to TN panels, VA displays have wider viewing angles and maintain better image quality when viewed from the side, although not as wide as IPS panels.
High Brightness:
VA panels can achieve high peak brightness levels, making them suitable for both bright and dark environments. However, the peak brightness might still be lower than that of high-end IPS or OLED displays.

Disadvantages of VA LCDs:
Limited Viewing Angles (Compared to IPS):
Although VA panels provide better viewing angles than TN, their viewing angles are still narrower than those of IPS panels. Colors and contrast may degrade when viewed from extreme angles (such as from the side or top/bottom).
Motion Blur:
VA panels have slightly slower response times than TN panels, meaning they may exhibit motion blur in fast-moving content, such as gaming or sports broadcasts. This can lead to ghosting or smearing of fast-moving objects.
Color Shift at Wider Angles:
While VA displays have better viewing angles than TN, they still suffer from color shifting when viewed from wide angles. This can be noticeable in applications where color accuracy is critical or when multiple people are viewing the screen at once.
