Final answer:
Vertical Alignment (VA) display technology is characterized by wide viewing angles and deep black levels, but not necessarily by fast refresh rates.
Step-by-step explanation:
Vertical Alignment (VA) display technology is known for a few distinct characteristics that are particularly beneficial for certain types of usage scenarios. One of the most notable features is its ability to deliver deep black levels, which contribute to a high contrast ratio and richer colors in the viewing experience. In addition to deep blacks, VA panels typically offer wide viewing angles, allowing the content on the screen to remain consistent even when viewed from an off-center position. However, VA technology is not typically known for fast refresh rates; this feature is more commonly associated with TN (Twisted Nematic) panels. Thus, when characterizing VA display technology, the correct answer would be 'b) Wide viewing angles' and 'c) Deep black levels'.
