Progressive Scan

It is used for most Cathode Ray Tube computer monitors. The other CRT-type displays, as televisions, classically use interlacing. This is also appearing increasingly general in high-end television element.

Advantages of progressive scan comprise:

  • raised vertical resolution. The perceived vertical resolution of an interlaced picture is generally equivalent to multiplying the active lines through about 1.6
  • No flickering of narrow horizontal models
  • Simpler video processing element
  • Easier compression
