CRT:TM-A210G

The TM-A210G is a 21" low end professional video monitor made by JVC. This monitor was marketed as a robust, yet economical CCTV color video monitor. Like most JVC monitors of the time, it uses a curved shadow mask tube. The monitor has a fairly low resolution 21" tube with 450 TV lines. Interestingly, the 17" version (TM-A170G) has a higher resolution tube of 750TVL.

Features
This monitor supports 480i/240p and 576i/288p only. Two composite inputs and one s-video input are provided at the back, without an option for input cards.

A brightness peak suppression feature is available, which is intended to extend tube life.

RGB Support
This monitor only supports composite and s-video out of the box.

The jungle IC allows for RGB insertion, but the CPU will normally continuously disable RGB via I2C. It is possible to intercept the I2C and filter out the "disable" commands. Immerhax has made a guide on how this can be done.
