UNSPSC 43211901: Cathode ray tube CRT monitors

A cathode-ray tube and associated electronics connected to a computers video output. A monitor may be either monochrome (black and white) or colour (RGB). Colour monitors may show either digital colour (each of the red,green and blue signals may be either on or off, giving eight possible colours: black, white, red, green, blue, cyan,magenta and yellow) or analog colour (red, green and blue signals are continuously variable following any combination to be displayed).

Digital monitors are sometimes known as TTL because the voltages on the red, green and blue inputs are compatible with TTL logic chips.

UNSPSC 43211901 Cathode ray tube CRT monitors is a Commodity code that shows no relevant recent activity in state and local procurement. The recent opportunities tagged under this code — including 10-inch Poseidon Celeron tablets procured by Hillsborough County Public Schools, a rural health data visualization platform from the South Dakota Department of Health, statewide Apple products from the Texas Department of Information Resources, a CAD-to-CAD interoperability system from the Washington Military Department, and SCADA system equipment upgrades from the City of Flowery Branch, Georgia — are plainly unrelated to cathode ray tube monitors. The code's nominal scope (CRT display technology) does not match the actual goods and services being solicited under its designation in the current marketplace.

The mismatch signals either a tagging error at the issuing-body level or a category designation that no longer reflects active state and local procurement practice. CRT monitor demand has effectively ceased in state and local government procurement; the opportunities showing up under this code are modern computing devices, cloud platforms, and industrial control systems. Business development professionals should not allocate pursuit resources to this code based on recent posting patterns.
