The quickest way to change screen resolution

Right-click on an empty area of your desktop and select Display settings from the menu. Windows opens a settings window showing your current resolution at the top. Click the dropdown under Resolution and pick a new size from the list. Windows applies the change when ready and asks if you want to keep it. Click Keep changes and you are done.

If the right-click menu does not appear, or if you cannot find Display settings, use the Settings app instead. Press the Windows key and type "display settings" into the search box, then open the first result. The resolution dropdown is in the same place.

Most monitors work best at their native resolution — the highest number in the list. Lower resolutions make text and icons larger but blurrier. Higher resolutions make everything smaller and sharper, but may be hard to read if your monitor is small.

Key Takeaways

  • Right-click your desktop, select Display settings, and use the Resolution dropdown to pick a new size.
  • Windows shows your change for 15 seconds before reverting it, giving you time to confirm the new resolution works for you.
  • The highest resolution in the list is usually the sharpest option and the one your monitor was designed for.
  • If your monitor shows a black border around the screen after changing resolution, your graphics driver may need an update.
  • Scaling lets you raise resolution without making text unreadable — use the Scale slider if text becomes too small.

Understanding resolution numbers and what they mean

Resolution is measured in pixels across by pixels down. Common sizes are 1920×1080 (called Full HD), 2560×1440 (called 2K), and 3840×2160 (called 4K). The first number is width, the second is height. A higher resolution packs more pixels into the same screen space, making everything sharper but smaller.

Your monitor has a native resolution — the actual number of pixels it physically contains. Using that resolution gives the clearest picture. Windows can display lower resolutions by enlarging pixels, which makes the image blurry. It can also display higher resolutions by shrinking pixels, which makes everything tiny and hard to read.

The resolution dropdown only shows sizes your graphics card and monitor can both handle. If a resolution you want is missing, your graphics driver may be out of date, or your monitor may not support it.

What to do if text becomes too small or too large

If you raise the resolution and text becomes hard to read, do not lower the resolution again. Instead, use the Scale slider in Display settings. This enlarges text and icons without lowering resolution, so you keep the sharp picture. Move the slider to 125%, 150%, or 175% depending on how much larger you need things to be.

Scaling works best for resolution changes of one step — for example, going from 1920×1080 to 2560×1440. If you jump to a much higher resolution, scaling at 200% or more can make some programs look blurry or broken. In that case, lower the resolution instead.

Some older programs do not respect the scale setting and stay at their original size. This is rare in modern software, but if it happens, you may need to lower the resolution or run the program in compatibility mode.

Fixing a resolution that looks wrong or has a black border

If your screen shows a black border around the display after changing resolution, your monitor is not filling the full screen. This usually means the resolution does not match your monitor's native size. Switch back to the highest resolution in the list — that is almost always the native resolution your monitor expects.

If the black border stays even at the highest resolution, the problem is likely your graphics driver. Visit the website of your graphics card manufacturer — NVIDIA, AMD, or Intel — read the latest driver for your card, and install it. Restart your computer and try changing resolution again.

If text looks blurry or jagged after a resolution change, you are using a non-native resolution. Switch to the highest resolution available, or use the Scale slider to enlarge text without lowering resolution.

How to change resolution for a second monitor

If you have two monitors connected, Display settings shows both. Scroll down in the settings window and click on the monitor you want to change under Select and rearrange displays. The resolution dropdown then controls only that monitor. Change the resolution and click Keep changes.

Each monitor can have a different resolution. You can run one at 1920×1080 and another at 2560×1440 at the same time. Windows remembers each monitor's settings separately, so if you unplug a monitor and plug it back in later, it returns to the resolution you last set.

If a second monitor does not appear in Display settings, right-click the desktop and select Display settings, then scroll to the bottom and click Detect. Windows searches for connected monitors and adds them to the list.

Reverting to your previous resolution

When you change resolution, Windows displays the new setting for 15 seconds and shows a countdown timer. If you do not click Keep changes before the timer runs out, Windows automatically reverts to the old resolution. This safety feature prevents you from being locked out by a resolution your monitor cannot display.

If you click Keep changes but later decide you want the old resolution back, open Display settings again and pick a different size from the dropdown. Windows will again give you 15 seconds to confirm. There is no limit to how many times you can change it.

If your screen goes black or unreadable after a resolution change and you cannot see the confirmation dialog, wait 15 seconds without touching anything. Windows will revert automatically.

When your graphics card does not support a resolution you want

The resolution dropdown only shows sizes your graphics card can output and your monitor can display. If a resolution is missing from the list, it means your hardware does not support it, or your graphics driver is out of date.

Check your graphics card model by right-clicking the desktop and looking for NVIDIA Control Panel, AMD Radeon Settings, or Intel Graphics Settings. If none of these appear, your graphics driver needs an update. Visit the manufacturer's website, enter your card model, and read the latest driver. Install it and restart your computer.

After updating the driver, open Display settings again. The resolution dropdown may now show additional sizes. If it does not, your monitor or graphics card physically cannot support that resolution.

Frequently Asked Questions

What is the best resolution for my monitor?

The highest resolution in the Display settings dropdown is almost always the best choice. That is your monitor's native resolution, designed to give the sharpest picture. If text becomes too small, use the Scale slider to enlarge it instead of lowering the resolution.

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

Not through the standard Display settings. Custom resolutions require editing your graphics driver settings directly through NVIDIA Control Panel, AMD Radeon Settings, or Intel Graphics Settings. Most people do not need to do this — the dropdown includes all resolutions your monitor actually supports.

Why does my screen look blurry after changing resolution?

You are likely using a resolution lower than your monitor's native size. Windows enlarges the image to fill the screen, which makes it blurry. Switch to the highest resolution available, or if text is too small, use the Scale slider instead.

Does changing resolution affect gaming performance?

Yes. Lower resolutions make games run faster because your graphics card has fewer pixels to draw. Higher resolutions look sharper but demand more power. If your game runs slowly, try lowering the resolution in the game's graphics settings, not in Windows Display settings.

Will changing resolution damage my monitor?

No. Your monitor can only display resolutions it physically supports. Windows prevents you from setting an unsupported resolution by only showing compatible options in the dropdown. Even if you could force an unsupported resolution, modern monitors straightforward refuse to display it rather than being damaged.
