Key Features    

  • Left/right swap
  • Left/right sync
  • Subsampling (side-by-side, top-and-bottom, quincunx)
  • Subsampling phase: even/even, even/odd
  • Display crosstalk (ghosting) measurement


  • Visually determine which monitors have the best ghosting performance without expensive test gear
  • Improve quality by avoiding cascaded and mismatched subsampling
  • Reduce viewer discomfort by eliminating left/right delay
  • Quickly measure lip-sync offset
  • Qualify equipment before purchase
  • Verify equipment designs
  • Quickly measure left/right sync

Visualizer test pattern screen

The Visualizer™ test pattern offers a comprehensive way to evaluate more than 20 key parameters of video quality from a single screen. Users can easily identify processing errors throughout the digital signal chain.

The CSM Color Space and Monitor test pattern suite tests displays and image processing systems for color space correctness and performance. CSM’s “eyes-only” design also reveals tradeoffs being made during conversion among various color spaces including High Dynamic Range (HDR) and Wide Color Gamut...

computer monitor with "VERIFY" on-screen

Using SRI’s Emmy® award-winning technology, the Sarnoff® Bitstreams™ suite is the de facto standard for systematically and unambiguously testing decoders against industry standards. It works in a matter of seconds and does not require a reference signal or specialized decoder.
