How do I connect a second monitor in Windows 10?

One of the features that has made personal computers so incredibly popular and revolutionized every aspect of our lives is their modularity. Thanks to hundreds of different types of connectors and ports, we can connect thousands of external devices to them. We’re talking about a very wide range of products—from drives providing additional terabytes of storage to precise controllers enabling convenient program control, to additional monitors that significantly enhance work comfort. This last solution is now very common—both in offices and private homes. However, how do you connect two monitorsso you can enjoy an expanded workspace while working on your computer?

How do I connect a second monitor to my computer? Choosing the right equipment

The first step is, of course, to buy a monitor. There are many products available on the market with different specifications, sizes, and technologies—for example, monitors with 15-inch or 17-inch screen sizes, which were still popular just a few years ago, are becoming increasingly rare, while large displays with screen sizes of 24, 27, or even 30 inches have become commonplace.

In addition to screen size, the technologies used are also important. CRT monitors, colloquially known as "tubes," are now considered retro equipment and are no longer mass-produced. This comes as no surprise—they clearly lag behind modern models in terms of performance and user-friendliness (not to mention their size!). In stores, you’ll still most often find LCD/LED monitors and slightly newer, but more expensive, OLED monitors. When it comes to LCD screens, the type of panel (IPS, VA, or TN). However, it all depends on the specific model and manufacturer.

An important factor from the user's perspective is the resolution supported by the monitor. For years, Full HD (1920 x 1080 pixels) was the standard, but as prices for 4K (3840 x 2160 pixels) and even 8K (7680 x 4320 pixels) monitors continue to drop, higher resolutions are slowly taking the lead. It’s worth remembering that the maximum resolution doesn’t determine how the monitor is used on a daily basis—for example, a 4K monitor will also support Full HD if we choose those settings. This is important, among other things, for technically demanding games, where the need to generate a huge number of pixels at high resolutions can exceed the computer’s processing capabilities. As a result, instead of a game, we’ll end up watching a slow “slideshow.”

If you want to know how to connect a second monitor, you need to remember that another important consideration is choosing how to connect it to your computer. Modern motherboards usually offer several types of video outputs:

• HDMI,

• DisplayPort,

• VGA (also known as D-sub),

• DVI (including DVI-A, DVI-I, and DVI-D).

While the last two types of connectors can still be found in desktop computers, laptops are usually equipped exclusively with newer ports such as HDMI or DisplayPort.

How to connect two monitors to a PC? Step-by-step guide

Connecting monitors with a cable isn’t the whole story. You still need to configure the system so that it displays the image on both screens correctly. Fortunately, Windows 10 includes built-in tools that make it easy to set up and use two monitors.

In the vast majority of cases, the system will automatically detect both monitors connected to the computer. In Windows 10, all you need to do is click Start, then Settings → Display → System. In Windows 11, the path is Start –> Settings –> System –> Display.

If the monitors haven't been identified, just click Detect, and the system will recheck the connected screens and assign them to the system settings Screen 1 or Screen 2 (you can assign these values manually later). In this menu, you can also set the desired resolution.

Working with two monitors in Windows

When you have two monitors connected, there are several ways to use them. Simply choose from the following options:

• Extend these screens – at this point, both monitors form a single workspace, and when the cursor crosses the “border” of the left screen, it immediately moves to the right screen (and vice versa),

• Duplicate – both screens display the same content, and you’re effectively working on a single screen. This makes sense, for example, when connecting a second monitor to a laptop, when you want to work on a large screen and don’t need the smaller display of the mobile device,

• Only the first screen and Only the second screen – turns off one of the monitors.

FAQ – Frequently Asked Questions

Can I connect monitors to different ports on the same computer?

Yes, the two monitors do not have to be connected via the same type of input.

Do two computer monitors have to be the same size?

No, you can connect, for example, a 15-inch and a 30-inch monitor and place them side by side.

Is DisplayPort better than HDMI?

This is a newer technology, so in theory it offers slightly better performance. However, for everyday computer use, this won’t make much of a difference. It’s also important to note that both HDMI and DisplayPort have several versions with different specifications.
