If you only have a single display for you PC, you will soon be interested in dual monitors, and then triple monitors, and so on and on. Monitors are like your paddles, and they proliferate autonomously regardless of your intention.
This is my first trial to use a monitor arm, which is now clamped on my new wooden rack. As soon as either of the two monitors proliferates, maybe on one of the long nights when there are no DX signals on the band, I will have a triple monitor system.
