Refresh rate refers to how many times per second a screen updates its image, measured in Hertz (Hz). For example, a 60Hz panel refreshes 60 times per second.
In simple words — higher refresh rates make visuals look smoother, especially when moving objects, animations, or scrolling content are involved.
Smooth Writing & Drawing: On smart boards, a higher refresh rate ensures lag-free touch response.
Better Video Playback: Makes motion look fluid during presentations or recorded lessons.
Reduced Eye Strain: Minimises flicker, providing a more comfortable viewing experience.
60Hz: Standard and sufficient for most educational and business needs.
75Hz–120Hz: Offers smoother interaction for advanced touch and video use.
When choosing an interactive display, go for at least 60Hz refresh rate — higher if your sessions involve video playback or fast-touch interaction.
