Display scaling issues are a surprisingly complex problem. Microsoft has been trying to improve display scaling for a long time. They have come a long way in making the best scaling experience for the users.
Different versions of Windows have various scaling capabilities and limitations. Not to mention older monitors tend to have more problems when connected to modern PCs. In the same way, your old PC may not be able to render proper graphics on modern high-end monitors.
What Causes the Display Scaling Issue in Windows?
Windows 10 has a built-in known issue with display scaling with Full HD and Ultra HD devices. This becomes problematic, particularly when used with external monitors. The following are some of the causes of display scaling in Windows 10:
Moving application windows between monitors that are using different display resolutions.
Using separate docked and undocked configurations on Windows. This includes detachable screens, docking stations, and tablet mode.
Using Remote Desktop session and then later direct login using the same credentials. This occurs primarily when the user doesn’t log off from the remote desktop session first.
Mixing high-resolution monitors with older monitors that don’t support High Definition displays.
How to Identify a Display Scaling Issue?
When you encounter a display scaling issue, you will see the following problems.
Applications, taskbar, icons, toolbars, and dialog boxes appear to be fuzzy
Some UI elements look larger or too small compared to other elements.
Blurry text across the screen or even in applications
External display blanking out for no reasons
How to Fix Display Scaling Issues
You may face the display scaling issue more than once if you use multiple monitors. Or even if you connect to one external display. Continue reading to find out how you can finally fix this issue for good. Try each of the following methods before moving to the next one below it to fix display scaling issues for good.
Match Screen Resolutions
When using more than one monitor, match the display resolutions as much as possible—the greater their difference, the more scaling issues. Older monitors have a limit on their display capacity. You need to set them to the recommended resolution. Then, on the high-resolution monitor, decrease the resolution to bring them as close together. Obviously, this will limit you from enjoying the full feature of the better monitor. But it should solve the scaling issue.
Log Out and Log Back in
Login/logout events determine the display information. Every time you log out and log back in, Windows resets the display configuration. This will fix your scaling issues right away.
Check for Software Updates
Software updates are the best way to fix known bugs and occurrences. If you haven’t updated your Windows, you may face display driver compatibility issues. Install the latest updates to improve the user experience and keep the system free of bugs.
Use UWP Applications
UWP or Universal Windows Platform applications are modern-looking applications that scale better. They look a lot better and perform better. UWP applications auto-adapt to the type of display you’re connected to. For example, Edge is a great UWP application compared to the legacy Internet Explorer app. Edge is built with newer tools with newer hardware in mind. So it is less likely to face scaling issues compared to Internet Explorer.
Disable Display Scaling

For example C:\Program Files\DAUM\PotPlayer.

Disable GPU Scaling.
Set Scaling Mode to Preserve aspect ratio.
Turn off Center or Fullscreen.
Set render resolutions to your Windows recommended display resolution.
