The correct way to connect two monitors to the same video source is to use a(n) ______.

To connect two monitors to the same video source effectively, utilizing a loop-through configuration is an appropriate method. A loop-through connection allows the video signal from the source to pass through to one monitor and then continue to the second monitor. This ensures that both monitors receive the same video signal without signal degradation.

In contrast, a splitter could theoretically duplicate the signal to both monitors, but it may lead to issues such as reduced quality or signal loss, especially if the monitors have varying resolutions or refresh rates. An adapter typically changes the format of the signal (for example, HDMI to VGA) rather than connecting multiple devices to the same source. A converter serves a similar purpose, changing one type of signal to another rather than facilitating connections between multiple monitors.

Loop-through connections maintain the integrity of the video signal, making it the most reliable option for simultaneously displaying the same video output on two separate monitors from a single source.
