What is Refresh Rate on a Screen?

Understand what refresh rate means, how it affects your viewing experience, and what to consider when choosing a screen.

Applies To

All CommBox Touchscreens and Commercial Displays

Step-by-Step Instructions

Step 1

Know what refresh rate means
Refresh rate is the number of times your screen updates the image every second. It’s measured in Hertz (Hz).

  • For example, a 60Hz screen refreshes 60 times per second.

Refer to CommBox Product Spec Sheets for the details of the refresh rates for each screen.

Step 2

Understand why refresh rate matters
A higher refresh rate creates smoother motion on your screen.

  • 60Hz: Standard for most tasks like web browsing, presentations, and documents.

  • 120Hz: Smoother visuals, ideal for video playback and light animation.

  • 144Hz and above: Great for gaming or high-speed content, where fast refresh reduces motion blur.

💡 Tip: For classrooms and meeting rooms, 60Hz is more than enough for smooth writing and video playback.

Step 3

Check or change your refresh rate settings
On most operating systems or devices, you can check or adjust the refresh rate in the display settings.

  • Windows: Right-click on the desktop > Display Settings > Advanced Display > Choose refresh rate

  • Mac: System Settings > Displays > Refresh Rate

  • CommBox Touchscreens: Settings may depend on the input source (e.g. OPS, external PC)

💡 Note: Your device and cable must support the higher refresh rate. HDMI 2.0 or DisplayPort is required for rates above 60Hz.

Troubleshooting / What to Do If It Doesn’t Work

  • Image looks choppy? Check if your refresh rate is set too low.

  • Can’t select a higher rate? Make sure your device, cable, and screen all support the desired refresh rate.

  • Using a third-party device? It might default to a lower refresh rate—check display settings on that device.
