How do I hook two monitors together?

why hook together ?
Just curious.

Do you mean setting up dual monitors? It can be a bit complicated. You should firstly check out your laptop or PC output and monitor input. In most cases, you should use different adapters. For instance, if your computer uses VGA output and your monitor supports an HDMI port, you may need a VGA to HDMI cable or adapter.
Repeat the same operation for your second monitor. Then you should adjust the “Multiple Displays” setting.
