Display test patterns

SMPTE/EBU bars, PLUGE, grayscale, geometry grid, solid fills. Fullscreen + downloadable.

The patterns that live on a USB stick in every commissioning bag. Pick a pattern, click Fullscreen to take over the browser window on the target display, or download as a PNG at 1080p / 4K / 8K to play through your normal media chain. SMPTE bars include the proper PLUGE sub-band so you can set black level at the same time.
