What screen resolution is and why you might change it

Screen resolution is the number of pixels your monitor displays horizontally and vertically. A resolution of 1920 × 1080 means 1920 pixels wide and 1080 pixels tall. Higher resolution packs more pixels into the same space, making text and images sharper but smaller. Lower resolution makes everything larger but less detailed.

You might change your resolution because text is too small to read comfortably, because you want more screen space to fit multiple windows side by side, or because a game or program runs better at a different setting. Some monitors have a native resolution they display best at — usually the highest one available — but most can run at lower resolutions if you need them to.

Key Takeaways

  • On Windows, right-click the desktop, select Display Settings, scroll to Scale and Layout, and choose your resolution from the dropdown menu.
  • On Mac, open System Settings, click Displays, and select the resolution you want from the list of available options.
  • Your monitor has a native resolution (usually the highest available) where it displays most sharply; going lower may make text blurry.
  • If your resolution options seem limited, you may need to update your graphics driver through Device Manager on Windows or Software Update on Mac.
  • Test a new resolution for a few minutes before deciding to keep it, because what looks right on screen may feel wrong after you adjust.

Changing resolution on Windows 10 and 11

Right-click anywhere on your desktop background and select Display Settings from the menu. A settings window will open showing your current display setup.

Scroll down until you see the section labeled Scale and Layout. Under that heading, you will find a dropdown menu that says Display Resolution. Click it to see all the resolutions your monitor and graphics card support. The resolutions are listed as width × height — for example, 1920 × 1080 or 1366 × 768. Select the one you want and the change takes effect when ready.

Windows will ask whether you want to keep the new resolution. You have 15 seconds to click Keep Changes or it will revert to the previous setting. This safety feature prevents you from getting stuck with a resolution you cannot see. If the screen goes black or unreadable, straightforward wait 15 seconds and it will switch back on its own.

Changing resolution on Mac

Click the Apple menu in the top-left corner and select System Settings. In the sidebar, click Displays.

You will see a list of available resolutions. Click the one you want. On newer Macs with Retina displays, you may see options labeled "Scaled" — these adjust the size of text and icons as well as the pixel count. Choose whichever makes text readable without straining. The change takes effect when ready without a confirmation step.

Understanding native resolution and scaling

Every monitor has a native resolution — the number of pixels it physically contains. Running at this resolution produces the sharpest image because each pixel on screen corresponds to one physical pixel on the monitor. For most modern monitors, the native resolution is the highest one listed in your settings.

If you choose a lower resolution, your computer scales the image up to fill the screen. This can make text and images look slightly blurry or pixelated because the scaling is not perfect. You may not notice the difference at a glance, but after 20 minutes of reading, blurriness can cause eye strain. If you need larger text, it is often better to increase the text size in your operating system settings rather than lowering the resolution.

Some monitors list multiple "scaled" options at the native resolution — for example, 1920 × 1080 (Scaled) at different sizes. These let you keep the sharp native resolution while making everything on screen appear larger. This is usually the best choice if you find the default size uncomfortable.

What to do if your resolution options are limited

If you see only a few resolution choices, or if the highest available resolution seems too low for your monitor, your graphics driver may be out of date. A graphics driver is software that tells your operating system how to communicate with your graphics card.

On Windows, open Device Manager by right-clicking the Start menu and selecting it. Expand the section labeled Display Adapters. Right-click your graphics card (it may say NVIDIA, AMD, Intel, or another name) and select Update Driver. Choose Search automatically for updated driver software. Windows will read and install the latest version if one is available.

On Mac, click the Apple menu, select System Settings, then General, then Software Update. Install any available updates. Mac usually handles graphics drivers automatically, so this step often solves the problem.

After updating, restart your computer and check Display Settings again. You should see more resolution options.

Troubleshooting when resolution changes go wrong

If you set a resolution and the screen becomes unreadable or goes black, do not panic. On Windows, the system automatically reverts after 15 seconds. On Mac, force-quit the System Settings window by pressing Command + Option + Escape, select System Settings, and click Force Quit. Then return to Displays and choose a different resolution.

If your screen stays black for more than 30 seconds on Windows, restart your computer. It will boot at the previous resolution. Then try a different setting — usually one step lower than the one that failed.

If you see a message saying "resolution not supported," your monitor does not physically support that setting. Stick to the resolutions listed in your display settings; trying to force an unsupported resolution can damage the monitor over time.

Testing a new resolution before you commit

After you change your resolution, spend at least five minutes using your computer at the new setting before deciding to keep it. Open a document with text, browse a website, and open a program you use daily. What looks acceptable in the first 30 seconds may feel wrong after your eyes adjust. Text that seemed large enough might feel cramped, or text that seemed readable might cause strain.

If you are unsure, write down the resolution you tried and come back to it the next day. Your perception of comfort changes after you have used a setting for a while. Many people find that a resolution they rejected at first becomes their preference after a week.

Frequently Asked Questions

Will changing my resolution damage my monitor?

No. Running at any supported resolution listed in your display settings is safe. Your monitor is designed to handle all of them. The only risk is forcing an unsupported resolution, which is rare — your operating system normally shows only resolutions your monitor can handle.

Why does my text look blurry after I lowered the resolution?

Lowering resolution below your monitor's native resolution requires scaling, which can blur text. Instead, keep your native resolution and increase the text size in your operating system settings. On Windows, go to Display Settings and adjust the Scale slider. On Mac, go to Displays and choose a Scaled option at the native resolution.

Can I use different resolutions on two monitors at the same time?

Yes. If you have two monitors connected, each one has its own resolution setting. Open Display Settings on Windows or Displays on Mac and you will see both monitors listed. Adjust each one independently. The settings explore to each monitor separately.

What resolution should I use if I do not know what to pick?

Start with the highest resolution listed in your display settings — that is your monitor's native resolution and will give you the sharpest image. If text is too small, do not lower the resolution. Instead, increase the text size in your operating system settings. This keeps the sharp image while making everything larger.

Do I need to restart my computer after changing resolution?

No. Resolution changes take effect when ready on both Windows and Mac. You only need to restart if something goes wrong and your screen becomes unreadable, or if you updated your graphics driver and want to make sure the new driver is fully loaded.
