It has been speculated that the JVC TM series uses some prefix and suffix letters to denote what features the monitor has:

  • A ??
  • H indicates monitor has a high-TVL M-class tube. For JVC this usually means > 750 TVL Chunghwa tubes.
  • C indicates the monitor has one or more option card slots on the back for input expansion.
  • G indicates global signal compatibility, which simply means the monitor supports both NTSC and PAL formats, as well as 120/240 volt AC input.
  • SU indicates the monitor has multiple additional features for video production such as external sync input, support for 16:9 mode, underscan, blue only, and other front panel toggles. In some cases all of these features are present on the monitor while in other cases only one or two.
  • CV may abbreviate "Color Video". Generally indicates the monitor is designed for CCTV applications (24/7 operation).
