The ability to attach a second monitor to your computer through HDMI, DisplayPort, or even an older model's VGA connector makes it simple to set up different displays on your computer. If you want to add a second monitor to your computer, here is an easy-to-follow guide.

  • Plug the two monitors into the back of your graphics card.
  • Many users mistakenly plug a monitor into the motherboard instead of the graphics card, resulting in a faulty display.
  • To change your desktop's display settings, right-click on the desktop and choose Display Settings.
  • Display Settings should automatically detect and represent both monitors by showing two boxes labeled "1" and "2" if two monitors are connected.
  • If your second monitor isn't listed here, click the Detect button to make your computer recognize both displays.
  • To configure the other monitor, select the grey box on the right. The presently preferred monitor is shown in bold on the settings page, and you may make changes to it by clicking on the arrow in the highlighted area.


As soon as you attach a second monitor to your laptop or desktop system, Windows will instantly recognize the monitor and display the computer's desktop screen. Once you've decided how you want your desktop screen to look, you may adjust things like display style (clone mode), screen resolution settings (just for the first screen), and color depth. It is possible to set up a multi-monitor arrangement with Windows 7 and above, which improves productivity.

Double Your Screen With Two Monitors!

Having numerous windows open on your desktop can make even a 24-inch display feel small. If you're confined to a laptop screen, it's considerably worse. Fortunately, adding a second monitor to your PC setup and spreading out are both simple processes.

Modern desktop and laptop PCs are equipped with graphics to operate two displays simultaneously. A second display is all that is needed. The supply of monitors has shrunk, as has been the case with so many other digital products this year. A few years ago, several decent monitors were available for under $100. You'll be hard-pressed to find a PC monitor with a 21-inch or larger screen for less than $150 nowadays. A 19.5-inch diagonal HP V20 HD+ Monitor costs $95, with TN technology for faster response times but less clarity off-axis. In terms of screen size, Dell's $140 SE2222H has a 22-inch screen with thin bezels that are great for keeping your two monitors from interfering with each other. For $145, you can get a 24-inch IPS panel with even smaller bezels from HP's V24i FHD Monitor. For an additional $190, you can get a 27-inch IPS panel from Dell with a resolution of 1920 x 1080.

VGA, DVI, HDMI, and DisplayPort connectors are commonly seen on today's monitors. To put it another way, you'll have a few options when it comes to connecting your PC display. Unlike VGA and DVI cables, which are typically bundled with displays, HDMI and DisplayPort cables may need to be purchased separately. Amazon has a wide selection of those.

You can also use your television as a second display by tapping it in an emergency, but this has some disadvantages. Everything you need to know about utilizing your TV as a computer monitor is included in this comprehensive guide. It doesn't matter whatever version of Windows you use; the procedure for configuring your monitors is the same.

How To Use Two Monitors At Once

  • The first step is straightforward. Connect your second monitor to a power outlet and a free port on your computer to get the best out of both monitors.

  • The next step is to instruct Windows on how to handle the two displays you've got. Display settings (Windows 7) or Screen resolution (Windows 8) can be selected from the desktop right-click menu (Windows 10). The configuration of the displays can be specified in the dialogue box that appears as a consequence. The Multiple Displays pull-down menu lets you configure how the two screens function together. When you select Extend these displays, Windows will handle all of your presentations as if they were a single unit.

  • Arrange your monitors in the order you want them to appear. Drag the screen icons at the top of the dialogue box to the left or right to inform Windows which monitor is left or right. If you get this wrong, you'll have difficulty scrolling the mouse.

  • It is the final step in the process. The taskbar and Start button are displayed on the monitor selected by selecting Make this my main display from the Display menu. Unless you see that option, your primary monitor is already the one you currently have selected.

If you right-click on the desktop and select your graphics control panel, you can change many of these settings.
