Why Are Black and White Squares Destroying Your Windows 11 Screen Experience?

How Can You Instantly Fix Those Terrible Black Squares Ruining Your Windows 11 Display?

Those black and white squares on your Windows 11 screen are more than just a minor inconvenience. They’re a clear sign something needs attention. Your computer is trying to tell you something important.

You’re working on an important project. Suddenly, strange squares appear everywhere. Your screen looks broken. This happens to many Windows 11 users. The good news? You can fix it.

What Causes These Screen Problems?

Several things can make these squares appear:

• Bad drivers – Your graphics card talks to Windows through drivers. When these go wrong, squares appear.
• Loose cables – A wobbly connection creates display problems.
• Overheating – Hot computers show visual glitches.
• Wrong settings – Incorrect display options confuse your screen.
• Software conflicts – Some programs don’t play nice with your graphics card.
