VA stands for vertical alignment, again referring to the crystal alignment. They can also have poor color and contrast due to this twist mechanism not being the most precise or accurate. TN panels are cheap but suffer from poor viewing angles due to the “twist” only being aligned in one direction for viewing the panel straight on. Consequently, TN panels are the only 240 hertz (Hz) gaming monitors available right now. This design allows for fast response times (the time between the panel getting the frame it’s supposed to display and actually displaying it).

Depending on the on or off (or in between) state, this crystal can twist polarization of the light 90°, thus matching the orientation of the second polarizer and letting it through. With TN panels, once the backlight is polarized into one direction, it enters the liquid crystals. These were the first LCD panels, and the tech behind them dates back to the 1980s.
