A Boland 8.4 HD monitor can exhibit inverted image display at startup, including reversed color bars and negative-looking video feed
The display issue may be temperature-dependent, with the monitor requiring several minutes to stabilize to normal operation after being powered on
Gently tapping the monitor case can restore normal display operation, suggesting an internal connection issue such as a cold solder joint or unseated component
The startup instability may be caused by a loose connection or component requiring reseating on the circuit board

The issue was specific to one unit and may not affect all Boland 8.4 HD monitors
The workaround of tapping the case is temporary; permanent repair requires internal inspection and potential component reseating
The root cause was not definitively identified without opening the device
