How to Use Your Laptop as a Monitor

If you’ve ever seen one of those movies that involved some high tech dude who appeared to be some sort of hacking genius working some magic in his lair, you would have noticed that it’s almost inevitable that this tech dude used more than one monitor at the same time.

Why Use More than One Monitor?

Truth is, using multiple monitors can prove to be extremely useful especially when functioning several different types of windows at the same time. According to Business.com, by simply adding an additional monitor as part and parcel of your daily technical requirements, you could be boosting your productivity by at least 20 to 30 percent. If you’re working an 8 hour shift, that’s 1.6 hours more efficiency you can achieve than if you were to stick with using just a single monitor.

If you walked into any investor’s office, you will notice that they operate their activities by using a multitude of screens ranging anywhere from the minimum two to four monitors at a time. Why? It’s handy especially when you need to make comparisons between windows as well as keeping track of all activities from different sources.

By using multiple monitors, you are able to drag your mouse to and fro between the monitors as well as drag programs and windows between them. Rather than having to switch between tabs and windows, you have expanded your screen’s real estate allowing you to look at all windows at the same time.

There are several applications to using multiple screens such as for the coder who wants to see different codes side to side, the gamer who wants to keep an eye on different gaming worlds at the same time, the multi-taskers who want to perform multiple activities simultaneously, and many more.
