2nd Laptop Makes A Great Monitor [Quick and Easy Trick]

2nd Laptop Makes A Great Monitor

A 2nd Laptop Makes A Great Monitor?

Hooking up a monitor to your laptop gives you more desktop space for apps or simply a bigger display to work on when you’re at a desk. We show you how to make it work. Laptops have become increasingly powerful over the last few years, but there’s one compromise that’s hard to overcome: a small screen.

Unless you’re going to carry a 17-inch monster around – and even a 17-inch screen is tiny by today’s standards – you’re forced to work on a display between around 11-15 inches.

So when you’re at a desk, it pays to hook up a large monitor to make things a bit easier. And you can even carry on using the laptop screen for extra desktop real estate.

An increasingly popular option is a portable monitor which you can carry around with your laptop and power from a USB-C port. Lenovo’s M14 – shown above – is a good example and isn’t horribly expensive at $199

Most laptops have at least one connector that can be used to plug in a monitor, be it HDMI, VGA, DVI, or Display Port. Some of the very thin laptops require an adapter as there isn’t room for a full-size Display Port or HDMI output, and this isn’t always supplied in the box. Although we’re talking about laptops, it is just as easy to connect a second screen to a PC: just have a look and see which ports are on the back.

If you haven’t already got a screen, then be sure to choose one with an input that matches your laptop’s output. Sometimes it’s possible to mix and match some of the digital options. For example, you can convert DVI to HDMI with a basic cable. But you cannot convert an analog signal (such as VGA) to digital, such as HDMI, without a box of active electronics: any passive cable you find for sale will not work.

The newest laptops may have only a USB-C port. This is the same physical connector you’ll find on most new Android phones,

Another option is to use a USB docking station that boasts one or more HDMI, DisplayPort, DVI or VGA ports, as well as extra USB ports, memory-card readers, Gigabit Ethernet for wired Internet access, and more.

You connect to the dock with a single USB cable and immediately gain access to all the dock’s ports.

Check if your laptop uses USB-C or the older USB-A (also known as USB 3.0) to choose the right dock.

How To Set Up A Second Screen in Windows?

Once you’ve connected the appropriate wire between your laptop and monitor (and supplied power to the monitor, if required) it’s time to configure Windows to use both screens.

In most cases, Windows will automatically detect when a monitor is plugged in and turned on and duplicate the contents of your laptop screen on it. If you don’t see anything on the screen, use its buttons to find the menu and see if you can select the correct video input as not all will automatically switch to an input with a video signal coming in.

Next, right-click on the Windows desktop and choose Display Settings. Or, click Start, Settings, and System. Here you’ll find options such as orientation, text size, and resolution.
