What is the result of incorrectly connecting the input cable to a splitter's output port and the TV cable to the input port?

When the input cable is incorrectly connected to a splitter's output port and the TV cable is connected to the input port, the designed function of the splitter is compromised. A splitter's primary purpose is to divide the signal from a single input source into multiple outputs for various devices, such as TVs.

In this scenario, the signal intended to be divided and sent to multiple TVs is not being properly routed. Instead, the signal is likely only reaching the TV connected to the designated input port of the splitter. Since this TV is still accessing the signal meant for the input but without proper distribution from the splitter, it may display a good picture if the signal strength is sufficient and the TV is properly tuned.

Conversely, the other TVs connected to the output ports may not receive any usable signal; thus, they are not able to display a picture. The faulty configuration means that only the single TV connected to the splitter’s input will potentially display a good picture, while the others either face disruption or complete lack of signal.

This clarifies why the selected answer accurately reflects the result of the misconnection.
