4:4:4 Test Pattern

The Extron 4:4:4 Test Pattern is an indispensable tool you can use to determine the color processing performance of your system. To ensure the best quality image, Extron scalers utilize 4:4:4 chroma processing which provides the most accurate reproduction of fine color detail. Scalers that employ 4:2:2 or 4:2:0 chroma processing may be adequate for full motion video, but significant signal degradation may be visible when viewing detailed computer generated content.

How to Use the Pattern

1. Open the pattern using the Launch button in the sidebar.
2. Click the “Download” button on the pattern to save a local copy to your computer (optional).
3. Double click the pattern to open it full screen.
4. Use your computer as a reference source by connecting it to one of your system’s video inputs.
5. View the pattern on one of the system’s displays.

What to Look For

The pattern will reveal if a device in the signal chain is processing at 4:2:2 or 4:2:0. This will result in loss of color information. Pay close attention to single-pixel lines and text. 4:2:2 or 4:2:0 processing will alter line color, thickness, or produce smearing. 4:4:4 processing retains fine color detail and maintains sharp transitions between colors.
