Does a white screen drain battery?

On LCD/IPS screens, a white screen consumes standard power. However, on OLED/AMOLED displays , displaying pure white uses maximum power because every pixel is fully lit. If you need to save battery on an OLED device, use our Black Screen Tool instead.

How do I fix a stuck pixel?

A stuck pixel (red, green, or blue dot) can sometimes be fixed by rapidly flashing colors. Try our Color Game or use a specialized pixel fixer tool that cycles colors at high speed to "unstick" the liquid crystal.

The Art of Contrast

Ratio Explained

Contrast Ratio is the difference between the brightest white and darkest black. High ratios (3000:1+) deliver inky blacks, while lower ratios (1000:1) can look gray in dark environments.

Dynamic Range

This test checks your panel's ability to show detail in both shadows and highlights simultaneously. "Crushing blacks" means losing subtle shadow detail, a common issue in poorly calibrated panels.

Professional Use Cases

HDR Mastering

HDR requires precise tone mapping. Verify your monitor's EOTF accuracy and highlight retention.

Print Proofing

Paper has limited contrast. Ensure your on-screen detail translates correctly to physical ink.

Competitive Strategy

Boost "Black Equalizer" settings to see enemies in shadows without washing out the image.
