How to Change DPI Settings in Windows 10

This guide shows you how to adjust the DPI (dots per inch) scaling in Windows 10 to make text, apps, and icons larger or smaller on your display. You’ll learn the built-in methods for changing scaling per display and per app, plus what to do when things look blurry or don’t apply correctly.

What You’ll Need

• A Windows 10 PC with an administrator account (for system-wide changes).
• Access to the Settings app (Windows key + I).
• Knowledge of your display’s native resolution (right-click desktop > Display settings > check under “Resolution”).

Step-by-Step

1. Open Display Settings: Right-click anywhere on your desktop and select Display settings from the context menu. Alternatively, press Windows key + I to open Settings, then click System > Display.
2. Locate Scale and Layout: In the Display settings window, scroll down to the Scale and layout section. This is where you control DPI scaling.
3. Choose a Scaling Percentage: Click the drop-down menu under Change the size of text, apps, and other items. You’ll see options like 100%, 125%, 150%, and 175% (the available options depend on your display and resolution). Select the percentage that suits your preference. Windows will apply the change immediately.
4. Sign Out and Back In (if prompted): Some changes require you to sign out and sign back in to apply fully to all apps. If you see a prompt, click Sign out now, then log back in. If you don’t see a prompt, the change is already active.
5. Custom Scaling (Optional): If the preset percentages aren’t enough, click Advanced scaling settings (under the drop-down). Turn on the toggle for Let Windows try to fix apps so they’re not blurry. Then, under Custom scaling, enter a value between 100% and 500% (e.g., 110 or 135). Click Apply. Note: custom scaling may cause some apps to appear blurry or be cut off.
6. Change DPI for a Specific App: If one app looks blurry or too small, right-click its shortcut (on desktop or Start menu) and select Properties. Go to the Compatibility tab, click Change high DPI settings, then check Override high DPI scaling behavior. Choose Application from the drop-down (or System if the app is old). Click OK twice. This forces the app to use its own scaling instead of Windows’ scaling.
7. Restart the App or PC: After applying changes, close and reopen the app, or restart your PC if changes don’t take effect immediately.

Common Mistakes

• Choosing too high a scaling percentage: Setting 150% or higher on a small screen (e.g., 13-inch laptop) can make elements too large, cutting off content.
• Ignoring resolution: If your display is set to a non-native resolution, scaling will look blurry. Always use the recommended resolution (usually marked “Recommended” in Settings).
• Using custom scaling without testing: Custom values like 110% or 135% can cause inconsistent scaling across apps, leading to blurriness or misaligned windows.
• Not signing out after a change: Some apps (especially older ones) won’t respond to scaling until you sign out and back in.
• Overriding DPI for every app: Only use the per-app override for apps that are actually problematic. Forcing it on all apps can cause layout issues.

Tips

• Use the recommended scaling: Windows suggests a scaling percentage based on your screen size and resolution. Start there and adjust only if needed.
• Keep your display at native resolution: This ensures text is sharp, regardless of scaling.
• For multiple monitors: Each monitor can have its own scaling. Select the monitor you want to adjust in the Display settings (click the numbered box) before changing the percentage.
• If text is too small but apps are fine: Use the “Make text bigger” slider under Ease of Access > Display instead of changing the overall scaling.
• Check for app updates: Many apps (like Adobe, Office) have their own DPI settings. Update them to ensure compatibility with Windows scaling.

Troubleshooting

• Change doesn’t apply: If the scaling percentage reverts or doesn’t stick, sign out and back in. If that fails, restart your PC. Also, make sure you have the latest Windows updates installed (Settings > Update & Security > Windows Update).
• Blurry text or apps: This often happens with custom scaling or older apps. Go to Advanced scaling settings and enable “Let Windows try to fix apps so they’re not blurry.” For specific apps, use the per-app override (step 6) and set it to Application.
• Some apps are cut off or have tiny text: The app may not support high DPI. Right-click the app’s shortcut, go to Properties > Compatibility > Change high DPI settings, and try setting the override to System (this lets Windows scale the app like a bitmap, which can fix cut-off text but may blur it).
• Scaling options are grayed out: This can happen if you’re using a remote desktop connection or if the display driver is outdated. Update your graphics driver (check manufacturer’s website) and ensure you’re connected directly to the monitor (not through a KVM switch).
• Custom scaling doesn’t appear in the drop-down: Custom scaling is only available via the “Advanced scaling settings” link. If you don’t see it, your Windows version may not support it (it’s available in Windows 10 version 1703 and later). Update Windows.

Frequently Asked Questions

What is DPI scaling in Windows 10?

DPI (dots per inch) scaling is a feature that adjusts the size of text, icons, and UI elements to make them readable on high-resolution displays. A 100% scaling uses the physical pixels as-is, while 150% makes everything 1.5 times larger.

What’s the difference between scaling and resolution?

Resolution is the number of physical pixels on your screen (e.g., 1920×1080). Scaling is a software multiplier that makes elements larger by using more pixels. You can have a high resolution with a low scaling (making things small) or a low resolution with high scaling (making things large but blurry).

Can I set a custom scaling percentage like 120%?

Yes, Windows 10 allows custom scaling from 100% to 500% via Advanced scaling settings. However, custom values may cause some apps to appear blurry or have layout issues, so test carefully.

Why do some apps look blurry after changing DPI?

Older apps that were not designed for high DPI displays may not scale properly. Windows tries to fix this automatically, but you can manually override scaling for a specific app via its Properties > Compatibility > Change high DPI settings.

How do I change DPI settings for only one monitor?

In Display settings, you’ll see multiple numbered boxes representing your monitors. Click the box corresponding to the monitor you want to change, then adjust the scaling percentage under “Scale and layout” for that monitor.

Will changing DPI affect gaming performance?

Yes, increasing DPI scaling means the GPU has to render at a higher internal resolution (if the game scales accordingly), which can reduce FPS. For games, it’s usually better to keep scaling at 100% and adjust the game’s own resolution or UI scale settings.
