Uses and Benefits to Extend Windows Screen

Extending Windows screen will provide more space for open windows and a larger view of websites, documents, and other content. It improves productivity for various tasks. Some of the key benefits of extending display on Windows include:

Gain more space for open windows, documents, and applications. With a larger display, you can comfortably view more items side by side.
Easier viewing of multiple windows side by side. An extended display gives you more width to arrange windows with less overlap.
Easier viewing of photos, websites, spreadsheets, or any other content. A bigger screen lets you see more detail without constantly zooming in and out.
Simplified multitasking. Having dedicated screens for different types of tasks makes it much easier to be productive. For example, keep email on one screen and browse the web on another.
Watch videos or play games on one screen while working on the other. Dual monitors give you the flexibility to have both recreational and productive content displayed at once.
Mirrored displays are great for presentations, teaching, and collaborating. You can show the same content on both screens so everyone has a clear view.

Prerequisites for Extending Your Windows Screen

To extend the display on Windows, you'll need:

A minimum of two monitors and the appropriate connection ports (HDMI, VGA, etc.). Use screens that are about the same size and have the same resolution for the best possible viewing experience.
Dual-screen support in your graphics card. Check the specifications to be sure, although most recent graphics cards can support two monitors. If it's an old system, then you may need to install a new graphics card.
Have the appropriate display drivers installed on your computer. Display issues sometimes stem from outdated driver software.

You will need to correctly connect and set up your second monitor to your Windows computer, and then you can start configuring the display settings to extend monitor.

Dual Monitor Not Extending? Here's What You Can Do?

If your Windows display is not extending to second monitor, or, according to some Windows users, dual monitor duplicates but not extending, try these fixes:

Fix 1: Double check that the correct option (Extend these displays) is selected under Settings > System > Display > Multiple Displays. If "Show desktop only on 1" or "Mirror displays" is chosen, the screens will not extend. Also, don’t forget to click the Detect button.

Fix 2: Ensure all monitor cables are properly and securely connected to both the displays and the PC. Loose or faulty cables frequently cause issues with dual monitors.

Fix 3: Try power cycling your monitors and restarting your PC. This refreshes the display settings and can resolve any temporary software issues preventing the displays from extending.

Fix 4: Update your graphics card driver to the latest version. Outdated drivers often cause problems with dual monitors and screen extensions. Downloading the latest drivers usually fixes these types of issues. Windows users can manually update or reinstall drivers using Device Manager in the taskbar. To do this:

Step 1.First launch the “Start” menu and search for “Device Manager”. Then left click on the app icon in the search results.
Step 2.In Device Manager, find your Display adapters, and locate the graphics adapter that is having a problem, then right-click your actual device and choose “Update driver”.

Step 3.Then follow the on-screen instructions to finish the process.
Step 4.If Windows doesn't find a new driver, you can try looking for one on the device manufacturer's website and follow their instructions.
Step 5.For example, you can go to the graphics card manufacturer's website (nvidia.com for NVIDIA graphics cards, amd.com for AMD graphics cards, etc.) and find your specific graphics card model.
Step 6.Then, click the "Download Center" or "Drivers & Support" section for your card model.
Step 7.Next, on the download page, select your operating system as Windows from the list. Then check the box next to the latest graphics driver for your card model and click "Download".

Step 8.When the download completes, double-click the installer file. Follow the prompts to install the driver. You may need to restart your PC to complete the installation.
Step 9.After the restart, check if your dual monitor setup is extending the displays as desired. If not, proceed to the other fixes.

Fix 5: If the previous steps haven't worked, the problem could be a hardware issue with your graphics card. You may need to reseat or replace the card to properly enable the screen extension. It's suggested that you contact a professional for assistance with hardware changes or repairs.

Fix 6: Check for any recently installed or updated software that may be interfering with the display settings. Some applications can disrupt the ability to extend screens. Uninstalling the problematic software may resolve the issue.

Extending Screen vs Mirroring Screen: Which One Is Better?

Extending your screen means each display shows a separate desktop, providing more total screen space. Mirroring or duplicating mode shows the exact same content on both screens. Here are the pros and cons of each method:

About Screen Extending:

Pros

Gives more usable space to view more open windows, files, and applications.
Allows each screen to have different content based on your current task.
Higher screen resolution than mirroring.

Cons

Can be difficult to setup correctly.
May require frequent adjustment of display settings as you arrange and open new windows.

About Screen Mirroring:

Pros

Simple to enable through Windows display settings.
Convenient for presentations, watching videos, or sharing content with others.
You are not limited to connecting a second monitor to your Windows computer, while you can screen mirror your Windows screen wirelessly.

Cons

Both displays are constrained to the lowest possible resolution, limiting screen space.
It is not practical for most productivity purposes where separate content on each screen is needed.

For typical day-to-day work or personal use, extending your Windows desktop across dual monitors offers significant advantages over mirroring mode. However, mirrored displays are useful in certain temporary situations, like giving a presentation or demonstration. The ideal setup for maximum productivity would be to extend your screen by default, then quickly enable mirroring mode when needed for sharing content.

More importantly, mirroring your Windows screen can be very easy, simply by a few clicks and you are done. What is surprising you is that you don’t need to set up a second monitor to mirror your Windows screen to any device using a third-party mirroring software. Wondering how to approach it? Check the following information.
