Check resolution in Windows settings

Open Settings by pressing the Windows key and typing "settings", then select the app. Go to System in the left menu, then Display. Scroll down to the section labeled Display resolution. The number shown there — something like 1920 × 1080 or 2560 × 1440 — is your monitor's current resolution.

If you have multiple monitors connected, click on the monitor you want to check in the diagram at the top of the Display settings page. The resolution shown will update to match whichever monitor you select. Windows lists the primary monitor first.

You can also right-click on your desktop, select Display settings, and you'll land on the same page. Some older Windows versions may show this under Settings > System > Display > Advanced display settings instead.

Find resolution on a Mac

Click the Apple menu in the top-left corner and select System Settings (or System Preferences on older macOS versions). Go to Displays. The resolution appears under a section labeled Resolution — you may see options like "1440 × 900" or "Scaled" with a resolution listed below it.

If you see "Scaled" selected, that means macOS is running at a different resolution than the monitor's native one. Click the resolution dropdown to see what options are available. The topmost option marked "Default for display" is usually the monitor's native resolution.

For external monitors connected to a Mac, the Displays settings will show each one separately. Select the monitor you want to check from the list on the left side of the window.

Check resolution in Linux

The steps vary depending on your desktop environment. In GNOME (used by Ubuntu and Fedora), click the system menu in the top-right corner, select Settings, then go to Displays. Your resolution appears under the monitor's name.

In KDE Plasma, open System Settings, go to Startup and Shutdown, then Display and Monitor. The resolution for each connected monitor is listed there. In XFCE, right-click the desktop, select Display Settings, and the resolution shows in the window that opens.

If you're using a terminal, you can type xrandr and press Enter to see all connected monitors and their resolutions listed in the output. Look for the line with a plus sign (+) next to it — that's your current resolution.

What the numbers mean

Resolution is always shown as two numbers: width × height, measured in pixels. A monitor set to 1920 × 1080 displays 1920 pixels across and 1080 pixels down. Common resolutions include 1366 × 768 (older laptops), 1920 × 1080 (standard for many desktop monitors), 2560 × 1440 (higher-end monitors), and 3840 × 2160 (4K monitors).

The first number is almost always larger because monitors are wider than they are tall. The ratio between the two numbers determines the monitor's aspect ratio — 1920 × 1080 is a 16:9 ratio, which is standard for most modern displays.

Higher resolution means more pixels packed into the same screen size, which makes text and images sharper. However, it also makes everything smaller on screen, so Windows and Mac offer scaling options to enlarge text and icons if needed.

Understand native versus current resolution

Your monitor has a native resolution — the number of pixels it was physically built to display. This is the sharpest setting. Your system may be running at a different resolution, which Windows or Mac then scales to fit your monitor. You can usually see both in your display settings.

If your current resolution is lower than the native resolution, text and images may look blurry because the system is stretching fewer pixels across the screen. If it's higher, everything becomes very small. Most of the time, setting your resolution to match the native resolution gives the clearest picture.

On laptops, the native resolution is fixed — you can't change the physical pixels. On desktop monitors connected to a computer, you can change the resolution in settings, but the monitor will look best at its native resolution.

Find the native resolution if settings don't show it

Check your monitor's manual or the manufacturer's website. Search for your monitor model number (usually printed on the back or bottom of the monitor) and look for the specifications sheet. The native resolution is listed there as "Maximum resolution" or "Native resolution".

You can also look at the monitor's on-screen menu. Press the menu button (usually near the power button) and navigate to Information or About. Some monitors display their native resolution in this menu.

If you're using a laptop, the native resolution matches what your operating system shows in display settings — laptops can't run at a resolution higher than what the screen physically supports.

Key Takeaways

  • In Windows, go to Settings > System > Display to find your resolution listed under "Display resolution".
  • On Mac, open System Settings > Displays to see your resolution, with the "Default for display" option showing the native resolution.
  • In Linux, the steps depend on your desktop environment, but GNOME, KDE, and XFCE all show resolution in their display settings.
  • Resolution is shown as width × height in pixels, and your monitor looks sharpest when running at its native resolution.
  • If you can't find the native resolution in settings, check your monitor's manual or manufacturer's website for the specifications.

Frequently Asked Questions

Why does my resolution look blurry even though I found the right number?

Your system may be running at a resolution lower than your monitor's native resolution, and Windows or Mac is stretching the image to fill the screen. Go back to display settings and select the highest resolution available — that's usually the native one. If blurriness continues, your monitor's native resolution may not match what your graphics card supports.

Can I change my resolution to something higher than what's shown?

No. The resolutions listed in your display settings are the only ones your graphics card and monitor can produce together. Choosing a resolution higher than what's available won't make your monitor sharper — it will either fail to explore or make everything look worse. Stick with the options your system shows.

My laptop shows a different resolution than my external monitor. Is that normal?

Yes. Each monitor has its own native resolution. Your laptop screen and an external monitor are different physical devices, so they can have different resolutions. Check each one separately in your display settings to see what each is running at.

What does "scaled" mean on my Mac?

Scaled means macOS is running at a resolution different from the monitor's native one and adjusting the display to fit. This makes text larger or smaller depending on which scaled option you pick. The "Default for display" option uses the native resolution, which is usually the clearest choice.

Does higher resolution use more battery on a laptop?

Slightly, but the difference is small. Higher resolution means your graphics card works a bit harder, which uses more power. However, the impact on battery life is usually less noticeable than screen brightness or what programs you're running.
