A user needs a technician's help connecting a laptop to a projector The projector is old and only has analog input. Which of the following cable types should the technician use to connect the laptop to the proJector?
Correct Answer: C
VGA stands for Video Graphics Array, and it is a type of cable that can be used to transmit analog video signals between devices, such as laptops, monitors, or projectors. VGA cables have 15 pins arranged in three rows, and they are usually color-coded blue. VGA cables can support resolutions up to 2048 x 1536 pixels, but they have low quality and limited color depth compared to modern digital standards such as HDMI or DisplayPort .
A projector is a device that projects an image or a video onto a large surface, such as a wall or a screen. A projector can have different types of input ports, such as VGA, HDMI, DVI, or USB. A projector can also have different types of output technologies, such as LCD, DLP, or LED .
In this scenario, the user needs a technician's help connecting a laptop to a projector. The projector is old and only has analog input. This means that the projector can only accept analog video signals, and not digital ones.
Therefore, the technician should use a VGA cable to connect the laptop to the projector, as it is the most common type of analog video cable. The technician should also make sure that the laptop and the projector have compatible VGA ports, and that the laptop's display settings are adjusted to match the projector's resolution and aspect ratio.
