Factors affecting cathode ray tube display performance.

Monitors are a complex combination of analog circuits that perform absolutely amazing feats of current and voltage control at both low and high frequency. Digital circuits can reduce the complexity of interfacing with the adjustments and even be used to build complex waveforms, but they cannot replace the point at which pure power is required. Five main topic areas are covered, each building on the other in how they relate to display performance. They are glass composition, resolution and addressability, phosphor selection and aging characteristics, light output and uniformity, and the tools available to assess display performance.
