What is the Role of Connectors in This Process?

If you have a problem with your LCD monitor, then the first thing you should do is check all of the plugged cables. They might be loose, not connected, or even disconnected from one another. How can you tell which cable goes where? First, try looking on either side of the back of the computer for any plugs and sockets. There will be labels telling how each socket is used and an illustration depicting what plug fits into which socket. If there isn’t information about this, look at the cord itself – each end has tiny colored dots near its edges. Connectors on those cords correspond to connectors on their respective devices according to these colors, making sure they match up and insert them properly onto both ends before trying to power up the monitor again.

If none of this works, you might want to try plugging your computer into a different outlet if there’s some problem with the electricity going to it and turning on both devices simultaneously. This should fix any electrical problems that could be causing horizontal lines on an LCD monitor, but if not, it may need to be replaced entirely.
