Dell low blue light display
WARNING: Prolonged exposure to blue light from the display may lead to long- term effects such as eye strain, eye fatigue, or damage to the eyes. The ComfortView feature on Dell laptops and displays is designed to minimize blue light emitted from the display for better eye comfort. To reduce the risk of eye strain after looking at the laptop’s display for an extended period of time, it is recommended that you: 1. Set the laptop’s display at a comfortable viewing distance between 20 inches and 28 inches (50 cm and 70 cm) from your eyes. 2. Blink frequently to moisten your eyes, or wet your eyes with water. 3. Take a break for 20 minutes every two hours. 4. 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.

Keyboard shortcuts of Precision 5550

NOTE: Keyboard characters may differ depending on the keyboard language configuration. Keys used for shortcuts remain the same across all language configurations.
Some keys on your keyboard have two symbols on them. These keys can be used to type alternate characters or to perform secondary functions. The symbol shown on the lower part of the key refers to the character that is typed out when the key is pressed. If you press shift and the key, the symbol shown on the upper part of the key is typed out. For example, if you press 2, 2 is typed out; if you press Shift + 2, @ is typed out.
The keys F1-F12 at the top row of the keyboard are function keys for multi- media control, as indicated by the icon at the bottom of the key. Press the function key to invoke the task represented by the icon. For example, pressing F1 mutes the audio (refer to the table below).
However, if the function keys F1-F12 are needed for specific software applications, multi-media functionality can be disabled by pressing Fn + esc. Subsequently, multimedia control can be invoked by pressing Fn and the respective function key. For example, mute audio by pressing Fn + F1.
NOTE: You can also define the primary behavior of the function keys (F1-F12) by changing Function Key Behavior in BIOS setup program.
