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

• A. Remote bright control box
• B. Central power panel
• C. Local brightness dial
• D. Operator console knob

Answer: (A)

Brightness for the terminal display workstation monitor is controlled with a remote brightness control box. This setup lets a central device set and standardize the luminance for the TDW displays, ensuring consistent visibility across different consoles and ambient lighting conditions. It also prevents individual operators from tweaking brightness on a monitor, which could lead to uneven or unintentionally altered levels during critical operations.

The other options don’t fit this standard arrangement: a central power panel handles power, not brightness; a local brightness dial on the monitor would allow each user to change settings independently, hurting uniformity; and an operator console knob isn’t the designated control path for this system.
