CMC‐1412A Monitor

The CMC−1412A was a VGA monitor offered by Leading Edge Products starting in 1991. The monitor had a 14" screen size with a non−glare coating with a maximum resolution of 640x480. The CMC−1412A was only compatible with VGA input signals, so it was unable to use signal output from CGA, EGA, MGA, or Hercules video adaptors. Leading Edge's CMC−1412A manual describes the monitor as, "…ideal for a wide variety of uses; from simple word processing to complex graphics programs. With its high quality screen and its compatibility with many types of computers and software, the Leading Edge Monitor is the perfect solution for any computing need".

Physical proportions of the CMC−1412A are a relatively standard size for its time. Measured from top to bottom including the angle adjusting stand, the monitor stood at 14" tall when adjusted to its maximum upward angle; at its maximum downward angle, it measured in at 12 ½" tall. From front to back, a user could have expected to allocate at the bare minimum 15 ¾", 17 ¾" would have been recommended to accommodate the fixed power and VGA input cables. Finally, the monitor's width measured in at 13 ¾". Leading Edge's CMC−1412A sported the styling typical of Leading Edge at the time. The monitor was wrapped in a business−like off−white plastic with subtle side and top ventilation grills. Back to the front of the monitor, at the right−hand side, the power switch was now a push−button switch that kept the button level with the rest of the monitor's' plastic bezel. Directly above the power button was a two−phase LED indicator that showed green when both power and signal was received, but amber when only power was received. To the monitor's front left, was the high−contrasting dark blue "LEADING EDGE" text and triple triangle logo.

To adjust the monitor, the typical user only needed two options via the two potentiometers on the lower right side of the monitor, brightness and contrast. Indeed, the monitor had a lot of adjustment available, but these adjustment potentiometers required a long slender and preferably plastic flathead screwdriver. A total of eight adjustment potentiometers were available from outside of the case's rear, these included: horizontal hold, horizontal phase, vertical line, vertical size with three additional fine tuners, focus, and screen ‐ which would adjust brightness with each push.

The tilt / swivel stand was easily removed if the user desired to lower the monitor to a fixed position. Simply inverting the monitor onto its top and carefully depressing two hold latches would have allowed the user to slide the stand off and out of the way. Reinstallation was an even simpler process after inverting the monitor with only the need to slide the stand into its guide slots until a click was heard.
