How to Fix AMD Radeon Screen Resize Problem in Windows 10?

Are you using an old version of AMD Radeon graphics like 3000 series?

Upgraded your monitor to full HD or even to a 4K monitor?

Then probably your Windows 10 doesn’t fit the screen. Right?

I just recently upgraded my monitor to BenQ which is a full HD monitor with resolution 1920×1080 and did face this issue.

Later upon installing the available AMD Radeon graphics driver, it doesn’t help me. But after some research, I got to know that editing the Windows 10 registry will fix this overscan or underscan problem of AMD graphics card. So, I just gave a try.

Voila! It worked.

Users of the forum even posted that this tweak to the registry did fix the 4000 series of AMD graphics too. So, if you have an outdated 4000 series of AMD graphics cards, you should try this one.
