Screen Resolution vs Display Scaling

Sometimes changing resolution is not the right solution. If text looks too small or too large, adjust scaling instead.

Scaling affects how CSS pixels map to physical pixels. Learn more here: What Is Device Pixel Ratio?

What Is the Best Screen Resolution?

The best resolution is usually the native (recommended) resolution of your monitor.

• 1080p monitor → Use 1920 × 1080
• 1440p monitor → Use 2560 × 1440
• 4K monitor → Use 3840 × 2160

Using a lower resolution than native may cause blurriness.
