FAQ

Q: What is VA LCD display?

A: VA stands for vertical alignment. The name comes from the vertical alignment of crystals. They are known as a cheaper but not the lowest cost option and are really a jack of all trades. VA panels still offer good colors especially when looking at contrast ratios, allowing for brighter whites and darker blacks.

Q: Is VA a good screen type?

A: VA panels strike a balance between performance and affordability, with good colour accuracy, high brightness, and excellent contrast, making them versatile for a range of use cases.

Q: Is LCD VA good?

A: Great All-Around, the Best Contrast, but Not the Fastest. When vertical alignment panel manufacturing emerged, LCDs gained color and improved viewing angles. VA panels produce a much bigger color space than TNs and have the most contrast of any LCD variety.

Q: Are all curved screens VA?

A: Contrary to popular belief, curved monitors can have other panel types, such as IPS (In-Plane Switching) and TN (Twisted Nematic). However, VA panels are often preferred for curved monitors due to their unique properties and advantages.

Q: Are VA screens LCD?

A: Contrast Ratio: VA panels typically offer the best contrast ratios among the three main types of LCD panels. This is due to their ability to block light more effectively when displaying dark scenes, resulting in deeper blacks and more vivid colors.

Q: Do VA monitors have bad viewing angles?

A: VA Panels: VA panels provide better viewing angles than TN, but picture quality still degrades if viewed from extreme angles. You can expect some color shift and contrast loss, though the effect is less severe than TN panels.
