Check your monitor resolution right now in your system settings

Your monitor's resolution is the number of pixels displayed horizontally and vertically on your screen — something like 1920 × 1080 or 2560 × 1440. You can find it in your operating system's display settings in under a minute, and you may already be using the resolution your monitor supports best.

The fastest way is to right-click on your desktop (Windows) or go to System Preferences (Mac), then look for Display or Screen Resolution. On Windows 11, search for "display settings" in the taskbar. On Mac, click the Apple menu, then System Settings, then Displays. Both will show your current resolution immediately.

If you want to know what resolution your monitor is capable of — not just what it's set to now — you'll need to check your monitor's manual or the manufacturer's website. Your computer might be running at 1920 × 1080 even though your monitor can handle 2560 × 1440. That's usually fine, but if you want sharper text or more screen space, changing the resolution might help.

Key Takeaways

  • On Windows 11, search "display settings" in the taskbar and look for the resolution listed under Scale and Layout.
  • On Mac, go to System Settings, click Displays, and the resolution appears at the top of the window.
  • On Linux, right-click the desktop and look for Display Settings, or open Settings and search for Displays.
  • Your monitor's maximum resolution is in its manual or on the manufacturer's website, not in your operating system.
  • Changing your resolution can make text sharper or give you more screen space, but very high resolutions on small monitors can make everything tiny.

Finding resolution on Windows 10 and Windows 11

On Windows 11, right-click anywhere on your desktop and select "Display settings" from the menu. A Settings window will open. Look for the section labeled "Scale and layout" — your current resolution appears there as a number like "1920 × 1080" or "2560 × 1440".

If you don't see it immediately, scroll down slightly. Windows also shows a dropdown menu that says "Recommended" next to the resolution number — that's the resolution Windows thinks works best for your monitor and text size.

On Windows 10, the path is slightly different. Right-click the desktop, select "Display settings," and scroll down to find "Resolution" listed under "Display." The current resolution appears in a dropdown menu. Click the dropdown to see other resolutions your monitor supports.

Finding resolution on Mac

Click the Apple menu in the top-left corner, then select "System Settings" (or "System Preferences" on older macOS versions). In the sidebar, click "Displays."

The resolution appears at the top of the window next to "Resolution:" — you'll see something like "1920 × 1200" or "3456 × 2234." If your Mac is connected to an external monitor, click the monitor's name in the sidebar first to see its resolution separately from your built-in display.

Mac also shows "Scaled" or "Default" next to the resolution. "Scaled" means your Mac is adjusting how large text and icons appear on screen, which can make everything look sharper but use more of your monitor's pixels. This is normal and doesn't mean anything is wrong.

Finding resolution on Linux

On most Linux desktop environments, right-click on the desktop background and look for "Display Settings" or "Settings." If that menu doesn't appear, open your applications menu and search for "Displays."

In the Displays window, your monitor will be listed by name (like "HDMI-1" or "DP-2"). Click it, and the resolution appears in a dropdown menu. The resolution marked with a checkmark or dot is your current one.

If you're using a Linux distribution without a graphical settings menu, you can also open a terminal and type xrandr to see all connected monitors and their resolutions. Look for the line with your monitor's name — the resolution appears after the monitor name with an asterisk next to the active one.

Understanding what the numbers mean

Resolution is written as width × height in pixels. A resolution of 1920 × 1080 means your screen displays 1920 pixels across and 1080 pixels top to bottom. Higher numbers mean more pixels packed into the same physical screen size, which usually makes text and images sharper.

Common resolutions include 1920 × 1080 (Full HD, standard for 24-inch monitors), 2560 × 1440 (2K, common on 27-inch monitors), and 3840 × 2160 (4K, used on larger monitors and TVs). Older or smaller monitors might run at 1366 × 768 or 1280 × 1024.

The relationship between resolution and screen size matters. A 27-inch monitor at 1920 × 1080 will have larger, blockier pixels than a 27-inch monitor at 2560 × 1440. A 24-inch monitor at 2560 × 1440 might make text so small it's hard to read without scaling.

Changing your resolution if you want to

If you want to try a different resolution, go back to your display settings and click the resolution dropdown. You'll see a list of resolutions your monitor supports. Select one and click "Apply" or "Keep Changes." Windows and Mac will ask you to confirm the change within 15 seconds — if you don't respond, it reverts automatically.

Higher resolutions give you more screen space but can make text smaller. Lower resolutions make everything larger but give you less room to work. If text becomes hard to read at a higher resolution, you can use your operating system's scaling or zoom feature to enlarge it without lowering the resolution.

Not all resolutions will be available for every monitor. Your computer only shows resolutions that your monitor actually supports. If a resolution you want isn't in the list, your monitor can't display it.

Finding your monitor's maximum resolution if it's not currently set

Your monitor might support a higher resolution than it's currently running at. To find out what your monitor is capable of, check its manual or the manufacturer's website — not your operating system settings.

Search for your monitor's model number (usually printed on the back or bottom of the monitor) plus the word "specifications" or "manual." The spec sheet will list the maximum resolution, refresh rate, and other details. If you can't find the model number, look for the brand name and approximate screen size — "Dell 27 inch monitor specifications" will usually get you there.

If your monitor supports a higher resolution than what's currently showing in your settings, you may need to update your graphics driver. On Windows, right-click the desktop and look for "NVIDIA Control Panel," "AMD Radeon Settings," or "Intel Graphics Settings" depending on your graphics card. On Mac, drivers usually update automatically. On Linux, check your distribution's package manager for graphics driver updates.

Frequently Asked Questions

Why does my monitor show a lower resolution than the manual says it supports?

Your graphics driver might be outdated, or your cable might not support the higher resolution. Try updating your graphics driver first. If that doesn't work, check that you're using the right cable — HDMI 1.4 and older versions don't support high resolutions, but DisplayPort and HDMI 2.0 do.

Will changing my resolution damage my monitor?

No. Your monitor can only display resolutions it physically supports, so your operating system won't let you set something it can't handle. Changing resolution is safe and reversible.

My resolution looks blurry after I changed it. What's wrong?

You may have set a resolution your monitor doesn't natively support, and Windows or Mac is scaling it, which can look fuzzy. Go back to display settings and choose the resolution marked "Recommended" — that's usually your monitor's native resolution, where everything will look sharpest.

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

Yes. In your display settings, click each monitor separately and set its resolution independently. Windows, Mac, and Linux all support this.
