Notes

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).

RGB Mod Information

The JVC TM Series can all be RGB-Modded using a method developed by immerhax. If your monitor has an option card slot, you are better off trying to find the RGB option card first before attempting to modify the monitor internally. There is a budget clone of the option card currently under development by immerhax.

The RGB Mod method involves using a programmed Arduino to help direct the monitor's blanking circuit while RGB is injected. In most cases the injection is done in factory RGB mode, meaning the monitor is aware it's displaying RGB content and therefore blocks any chroma/color adjustments on the front panel (displays "Not allowed" when you try).

The instructions can be found on immerhax. If the website ever goes down, here is a mirror for the TM-A101G instructions.
