Which of the following steps should you take when maintaining monitors? (Choose all that apply.)
a. Do not block ventilation holes in CRT and LCD displays.
b. Use antistatic cleaners made for electronics to clean screens and other surfaces.
c. Do not spray cleaners directly onto screens or enclosures.
d. Use thumbscrews to hold CGA and DVI cables in place on displays, projectors, and video cards.
e. When a system is opened for upgrades or service, check the condition of the cooling features of the video card. Remove hair, dust, or durt in or on the heat sink, cooling fan, fan shroud, or heat pipe radiator. Make sure airflow around and behind the video card is not obstructed by cables, dirt, dust, or other components.
f. Allow plenty of clearance around the video card slot. Don't use the slot next to the video card if the card would limit airflow to the video card's cooling features.
