ComfortView Plus
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.
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.
The display on this computer is designed to minimize blue light and complies with TÜV Rheinland's requirement for low blue light
displays.
Low blue light mode is enabled at the factory, so no further configuration is necessary.
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 and 70 cm) from your eyes.
● Blink frequently to moisten your eyes, wet your eyes with water, or apply suitable eye drops.
● 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.
● Take an extended break for 20 minutes every two hours.

Keyboard shortcuts of Latitude 7440
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, multi-media 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.

Table 28. List of keyboard shortcuts

Function key Primary behavior
F1 Mute audio
F2 Decrease volume
F3 Increase volume
F4 Play previous track/chapter
F5 Play/Pause
F6 Play next track/chapter.
F8 Switch to external display
F9 Search
F10 Click keyboard backlight (optional).
NOTE: Non-backlight keyboards have F10 function key without the
backlight icon and do not support toggle keyboard backlight function.

NOTE: Toggle to cycle the keyboard backlight status through off, low-
backlight, and high-backlight

F11 Decrease brightness

F12 Increase brightness

The Fn key is also used with selected keys on the keyboard to invoke other secondary functions.
