Why do some clients require dual monitors?
Dual monitors make it easier to navigate through multiple screens. When I first started out years ago, I only had one monitor. Now that I use two, I can’t imagine going back to one. Monitors only need an HDMI or USB cord to connect to your computer, and the client typically does not provide this. However you can pick up one at Best Buy for around $15. Personally, I use my television as my second monitor. (just a tip)
