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.

Comment jouer

Color Discrimination

This challenge tests your Delta E sensitivity. Professionals can distinguish differences as low as dE 1.0, while untrained eyes often struggle under 3.0.

The Monitor Factor

Low-quality TN panels with poor viewing angles make this game nearly impossible. IPS and OLED panels provide the color accuracy needed for high levels.
