Summary
19" (18" viewable) professional monitor from JVC. It is similar to the TM-1950CG, but is missing the input card slot and some of the broadcast-specific features like the tally light and blue-only mode. It includes two composite and one S-Video inputs, and can also modified for RGB.

Notes
This model shares the same chassis design as the TM-H1700G, and can be modified for RGB input using the same method (see instructions above).
The plastic used in this model (and other JVC monitors from this time period) is very brittle, and the front buttons often break off (especially the power button). Patterns for 3D printed replacements are available.
Also, the front bezel is susceptible to cracks; for this reason it should be handled with care. These monitors are difficult to ship safely, and often suffer damage in transit.
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).
