CompTIA A+ 220-1101 Practice Question
A newly installed high-end projector in an executive boardroom is projecting a clear image along the edges but displays a noticeable blur in the center areas during its first use in a presentation. Prior inspection indicates the lens and external components are clean and unobstructed. After ensuring connection integrity, which of the following should be executed next to effectively mitigate this specific issue?
Perform a firmware software update for the projector to the latest version.
Recalibrate lens properties directly via projector settings if adjustable.
Decrease the output resolution to reduce strain on projector's lens clarity.
Clean the lens internally presuming a possible overlooked contamination.
