Touchpad
A touchpad is available on most laptops and provides the functionality of a mouse. It has a touch-sensitive surface that senses the
motion and position of your fingers. You can use the touchpad to move the cursor, drag or move selected items, and click by tapping
the surface. Gesture‑enabled touchpads support gestures such as zoom, pinch, rotate, scroll, and so on. You can also purchase
external touchpads. A precision touchpad is a new class of input device that provides high precision pointer input and gesture
functionality. Precision touchpads interact with the operating system directly without the need for a driver.
NOTE: For more information, see Using your touchpad.
Display
Displays are classified according to their screen size, resolution, color gamut, and so on. Generally, a screen with higher resolution
and better color support provides better image quality. Some external displays also have USB ports, media-card readers, and so on.
Displays may also support features such as, touch screen, 3D, and wireless connection.
Touch screen
Touch screen is a display device that lets you interact with the objects on the screen by touching the display instead of using a mouse,
touch pad, or a keyboard. You can operate a touch screen with a finger, or another passive object, such as a stylus. Touch screens
are commonly used in phones, tablets, computers, and so on. Commonly used touch screen technologies are capacitive touch and
resistive touch.
NOTE: Touch screen may not be supported on all computers.
NOTE: For more information, see Using your touch screen.
3D
3D-capable displays can display 3D images and videos. 3D works by presenting separate 2D images to the left and right eye. These
images are combined and interpreted by the brain as one image with depth.
NOTE: You may need specially designed 3D glasses to view 3D images.
Wireless display
The wireless display feature enables you to share your computer display with a compatible TV without the use of cables. To check if
your TV supports this feature, see the documentation of the TV.
NOTE: Wireless display may not be supported on all computers. For more information, see www.intel.com.
