What must the TMA monitor display before shutting down the computer?

• A. Searching or no video
• B. Video is active
• C. Standby
• D. Error

Answer: (A)

The main idea is that you should only power down when there isn’t an active video signal showing on the display. The TMA monitor should be in a state where it’s either actively trying to find a signal but hasn’t found one yet, or it’s showing no video input. These states confirm there’s no ongoing display of content that could be interrupted by shutting down.

If video is currently active, shutting down could cut off something that’s being shown or processed, which isn’t safe. If the monitor is in standby or shows an error, there may be unresolved conditions that could cause issues when you power everything off. So, the recommended condition is that the monitor displays searching or no video before shutting down.
