Having Video Wall Blues

You’ve just acquired a video wall, and it looks awesome in person! You can’t wait to show it off, so you take out your phone to capture a video, and then you notice something peculiar. Your video wall doesn’t look good on camera. It’s covered with strange lines and patterns. This is a catastrophe! You live-stream your event every week, and you need your video wall to look great. You have just witnessed the moiré effect.

What is the Moiré Effect?

The moiré effect occurs when two regular patterns overlap or are slightly out of alignment, creating an unwanted visual interference pattern. In the context of LED video walls, this effect can manifest as distracting, wavy patterns or shimmering lines across the display, particularly when capturing images or videos with cameras. This phenomenon is present across all video walls regardless of manufacturer.

Causes of the Moiré Effect

Several factors can contribute to the moiré effect on LED video walls:

  1. Pixel Misalignment: If the pixel pitch of the LED panels is not uniform or if there is misalignment during installation, it can lead to interference patterns.
  2. Camera Interaction: When capturing images or videos of the LED display, the camera’s sensor grid can interfere with the pixel structure of the display, causing moiré patterns.
  3. Content Resolution: Content with fine patterns or high-frequency details may exacerbate the moiré effect.

Combatting the Moiré Effect

To mitigate the moiré effect and ensure a superior viewing experience, it’s essential to implement effective strategies:

  1. Optimal Refresh Rate: Setting a high refresh rate, helps minimize flickering and reduces the likelihood of moiré patterns appearing, especially when capturing video footage.
  2. Pixel Configuration: Ensuring precise pixel configuration and alignment during installation can significantly reduce the occurrence of moiré patterns on the display.
  3. Content Optimization: Avoiding content with intricate patterns or high-frequency details can help prevent the moiré effect from becoming noticeable.
  4. Camera Settings and Positioning: Pre-setting the camera’s settings and position to align with the LED display’s pixel structure can help minimize interference patterns in live streams or recordings. Adjusting the focus, aperture, and shutter speed can further optimize the capture quality and reduce moiré effects.
