Computer Display Adjustment Tips by Brand — Resolution, Refresh Rate, Color Calibration, and HDR
Proper computer display adjustment makes text sharper, colors more accurate, and games smoother. Apply the five-minute routine and brand-specific utilities below to improve most issues right away.
5-Minute Quick-Fix Routine
- Resolution/scaling: Use Windows’ recommended resolution and scale; use the recommended scaling option in macOS.
- Refresh rate: Set it to 120/144/165/240Hz in Advanced display settings.
- Sharpness: Use Windows ClearType; on macOS, confirm that you are using the native resolution.
- Color: Turn OFF Night Light/True Tone and apply the monitor-specific ICC profile.
- HDR/VRR: Turn them ON only when needed, and enable VRR for gaming.
Key Concepts
- Resolution = number of pixels (native is recommended); scaling = text size; refresh rate = smoothness
- Understand color spaces/ICC profiles and the characteristics of HDR
