...is crucial.

Therefore, only flat-square shadow-mask, or aperture-grille tubes are recommended.

• Aperture-grille tubes with multiple comb filters are the traditional choice, but recent advances in shadow mask technology, such as multiple inline electron scanning guns to both increase overall lunimosity and cut down on lateral artifacts, and engineering techniques which help minimize moire distortion, are making shadow mask display devises and interesting and fully functional alternative.
  
  
• For precision multimedia work, a display device should support vertical refresh rates of 75Hz or higher at all resolutions the device supports. This feature is increasingly becoming standard in most multiscanning monitors. Of course, non-interlacing display is mandatory.
  
  
• Connectors are also an element to consider. BNC-5 locking connectors provide the best results, with color channel isolation and bi-directional sync separation. For proper calibration to local environmental conditions, control over pincushioning, barreling, and color convergence, color temperature, gamma, and gun focus for each color channel are important.
