What is the minimum refresh rate required by the Super VGA (SVGA) standard?

The minimum refresh rate required by the Super VGA (SVGA) standard is indeed 70 Hz. This standard was introduced to improve upon the capabilities of the original VGA (Video Graphics Array) standard, which typically supported a refresh rate of around 60 Hz at lower resolutions. The increase to 70 Hz was significant because it allows for a smoother display experience, reducing flicker, particularly at higher resolutions.

Refresh rates are critical in determining how comfortably users can view displays for extended periods; higher rates typically result in less strain on the eyes. The SVGA standard brought enhancements not only in resolution but also in refresh rates to align better with user preferences for visual clarity and performance. Therefore, a refresh rate of 70 Hz became a baseline requirement to accommodate these advancements in display technology and provide users with a more stable viewing experience.
