Where is the terminal display workstation (TDW) monitor's brightness controlled?

The terminal display workstation (TDW) monitor's brightness is controlled at the remote bright control box. This control box is typically used for adjusting the brightness settings without needing to access the monitor directly. It allows personnel using the TDW to easily make brightness adjustments from a distance, which is particularly useful in settings where direct access to the monitor may be limited or less convenient. By using a remote control method, operators can ensure optimal visibility and comfort during use, enhancing the overall user experience.

Adjusting brightness at a local port would not provide the flexibility that a remote control box allows, and while the contrast/brightness control panel on the DEC might sound plausible, it typically does not directly handle brightness for the TDW monitor specifically.
