Plan Perfect Video Wall Timings with DEXON’s Free Tool

In professional AV projects, timing precision is critical. When integrating video walls, LED displays, or multi-display systems, a mismatched signal can cause issues like flickering, black screens, or pixel misalignment. To simplify system planning and reduce on-site troubleshooting, DEXON Systems offers a powerful and free tool: the Video Timing Calculator.

This online video wall timing calculator allows integrators to input any resolution and refresh rate — including non-standard or custom values — and instantly get the full timing breakdown according to multiple industry standards like CVT, CVT-RB, CVT-RBv2, and CEA-861. These standards define how video signals are structured at the pixel and line level, which is critical for seamless operation across source devices and displays.

Real-World Example of the video wall timing calculator:

1920x1080 at 60 Hz

Let’s say you're setting up a 1080p video wall running at a standard 60 Hz refresh rate — commonly used across professional AV environments.

Using the DEXON Video Wall Video Timing Calculator, here are the results you’ll get:

This level of detail is essential when you need to:

• Ensure compatibility between sources and devices
• Avoid visual artifacts like frame tearing or unsupported signal formats
• Optimize pixel clock for cabling scenarios such as long HDMI or SDVoE transmission

Whether you're working with LED walls, LCD screens or multi-screen video walls, understanding blanking intervals and sync values ensures smooth playback, accurate scaling, and a better overall user experience.

How the video wall calculator works?

Fully Customizable – Any Timing, Any Standard

This calculator is especially useful when you're using it with DEXON systems' Custom Output Timing and Custom EDID functions. For instance, in one of our recent projects, a monitor failed to recognize a 2160p50 signal when using default CVT timings. But once we set up a CEA-type custom timing and applied it via Custom Output Timing, the monitor accepted the signal flawlessly.

If you're preparing a setup with a non-standard aspect ratio, this calculator will also help you generate valid timing values for both EDID configurations and the Custom Output Timing function.

One of the best features of DEXON’s tool is that you can input any combination of resolution and refresh rate — not just standard ones. This makes it ideal for environments requiring custom resolutions, asymmetrical displays, or unusual frame rates (e.g., 50 Hz, 75 Hz, 100 Hz).

Even if you're preparing a setup with a custom-built LED wall or non-standard aspect ratio, the calculator will help you generate valid timing values.

Thanks to this flexibility, the calculator becomes a natural extension of your AV system design workflow and helps you save time, avoid signal errors, and deliver smoother installs.
