Finding your screen resolution in Windows, Mac, and Linux

Your screen resolution is the number of pixels displayed horizontally and vertically on your monitor — for example, 1920 × 1080 means 1920 pixels wide and 1080 pixels tall. You can check it in your operating system's display settings in under a minute, and the steps differ slightly depending on whether you use Windows, Mac, or Linux.

The fastest way on any system is to search your settings for "resolution" or "display" and look for a line that shows two numbers separated by an × symbol. If you need to change your resolution after checking it, the same settings panel will let you do that.

Key Takeaways

  • Windows users can find resolution by right-clicking the desktop, selecting Display Settings, and scrolling to the Resolution dropdown.
  • Mac users open System Settings, click Displays, and read the resolution listed under the monitor name at the top of the window.
  • Linux users open Settings, navigate to Displays, and see the resolution in the dropdown menu or as text on the screen.
  • Your resolution affects how sharp text and images appear — higher numbers mean more pixels packed into the same physical space.

Checking resolution on Windows 10 and Windows 11

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

Scroll down until you see a section labeled Resolution. The current resolution appears in a dropdown menu. If you see a number like 1920 × 1080 or 2560 × 1440, that is your resolution. Windows also shows a recommended resolution below the dropdown — if your current resolution does not match the recommendation, your monitor may look slightly blurry or stretched.

If you cannot find Display Settings by right-clicking, open the Settings app directly by pressing the Windows key and typing "display settings," then press Enter.

Checking resolution on Mac

Click the Apple menu in the top-left corner and select System Settings (on newer Macs) or System Preferences (on older ones). Then click Displays in the sidebar.

At the top of the window, you will see your monitor's name. Below it, look for a line showing the resolution — it will appear as two numbers with an × between them, such as 2560 × 1600. If you see the word Scaled next to the resolution, your Mac is adjusting the display to make text larger or smaller than the native resolution.

Checking resolution on Linux

Open your system's Settings application — the exact name and location varies by Linux distribution, but it is usually called Settings, System Settings, or Control Center. Look for a Displays or Screen option in the sidebar.

Your resolution will appear in a dropdown menu or as text on the screen, typically showing a number like 1920 × 1080. Some Linux systems also show the refresh rate (how many times per second the image updates) next to the resolution.

What the numbers mean

Resolution is measured in pixels — tiny dots of light that make up everything you see on screen. The first number is how many pixels stretch across the width of your monitor, and the second is how many stack from top to bottom. A 1920 × 1080 monitor has 1920 pixels horizontally and 1080 vertically, for a total of about 2 million pixels.

Higher resolution means more pixels in the same physical space, which makes text and images appear sharper. A 27-inch monitor at 1440 × 2560 will show sharper detail than the same monitor at 1920 × 1080, because the pixels are smaller and closer together. However, higher resolution also makes text and buttons smaller on screen, which is why some people prefer lower resolutions on large monitors.

Why your resolution might not match the recommendation

Windows and Mac both show a recommended resolution for your monitor. If your current resolution is lower than recommended, your monitor is not displaying at its native resolution — the resolution it was designed for. This usually makes text look slightly blurry or soft.

If you are seeing a lower resolution than recommended, your graphics driver may need an update, or you may have accidentally changed the setting. Updating your graphics driver (the software that controls your monitor) often fixes the problem. On Windows, you can update drivers through Device Manager; on Mac, check for system updates in System Settings.

Changing your resolution if needed

If you want to change your resolution, the same settings panel where you checked it will let you do so. In Windows, click the Resolution dropdown and select a different option. On Mac, click the Scaled button and choose a different resolution. On Linux, click the resolution dropdown and select a new one.

After you change the resolution, your screen may go blank for a few seconds while it adjusts. If the new resolution makes text too small or too large to read comfortably, you can change it back the same way. Most systems give you 15 to 30 seconds to confirm the change before reverting automatically.

Frequently Asked Questions

What if I do not see a resolution option in my settings?

Your graphics driver may be missing or outdated. On Windows, open Device Manager, find Display Adapters, right-click your graphics card, and select Update Driver. On Mac, check for system updates in System Settings. If you are using an external monitor, make sure it is connected with a working cable.

Why does my resolution show as lower than what my monitor supports?

Your graphics driver may not recognize the monitor's full capabilities, or the cable connecting the monitor to your computer may not support higher resolutions. Try updating your graphics driver first. If that does not work, check whether you are using the correct cable type — HDMI 2.0 and DisplayPort support higher resolutions than older HDMI 1.4 cables.

Does higher resolution use more battery power?

Yes, slightly. Higher resolution means your graphics processor works harder to draw more pixels, which drains battery faster on laptops. If you are trying to extend battery life, lowering your resolution will help, though the difference is usually small — around 5 to 10 percent.

Can I set a custom resolution that is not in the dropdown?

On Windows, you can create a custom resolution through your graphics card's control panel — right-click the desktop and look for NVIDIA Control Panel, AMD Radeon Settings, or Intel Graphics Settings depending on your card. On Mac and Linux, custom resolutions are not normally supported without advanced configuration.
