ComfortView
Blue light is a color in the light spectrum which has a short wavelength and high energy. Chronic exposure to blue light, particularly from digital sources, may disrupt sleep patterns and cause long-term effects such as eye strain, eye fatigue, or damage to the eyes.
Dell ComfortView software technology reduces harmful blue light emissions to make extended screen time easy on your eyes.
ComfortView mode can be enabled and configured using the Dell CinemaColor application.
ComfortView mode complies with TÜV Rheinland's requirement for low blue light displays.
To reduce the risk of eye strain, it is also recommended that you:
- Position the display at a comfortable viewing distance between 20 and 28 inches (50 cm and 70 cm) from your eyes.
- Blink frequently to moisten your eyes, wet your eyes with water, or apply suitable eye drops.
- Take an extended break for 20 minutes every two hours.
- Look away from your display, and gaze at a distant object at 20 ft (609.60 cm) away for at least 20 seconds during each break.
Dell Optimizer
Dell Optimizer is an AI-based software application that allows you to customize your computer settings for power and battery, and more.
- Extend the battery life of your computer with Intelligent Battery Extender and Dynamic Charge.
