As dp is a physical unit it has an absolute value which can be measured in traditional units, e.g. for Android devices 1 dp equals 1/160 of inch or 0.15875 mm. While traditional pixels only refer to the display of information, device-independent pixels may also be used to measure user input such as input on a touch screen device.
DisplayPort connector A DisplayPort port (top right) on a laptop from 2010, near an Ethernet port (center) and a USB port (bottom right). DisplayPort (DP) is a proprietary [a] digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA).
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
Since Android 1.6 "Donut" (September 2009) [12] Android has provided support for multiple screen sizes and densities. Android expresses layout dimensions and position via the density-independent pixel or "dp" which is defined as one physical pixel on a 160 dpi screen. At runtime, the system transparently handles any scaling of the dp units, as ...
Byte number (decimal) within this block where the 18-byte DTDs begin. If no non-DTD data is present in this extension block, the value should be set to 04 (the byte after next). If set to 00, there are no DTDs present in this block and no non-DTD data. 3 With version 2 and up: number of Native DTDs present, other information.
The aspect ratio also affects the perceived size of objects on the screen. [5] The native screen resolution together with the physical dimensions of the graphics display can be used to calculate its pixel density. An increase in the pixel density often correlates with a decrease in the size of individual pixels on a display.

On two-dimensional display devices such as computer monitors the display size or viewable image size is the actual amount of screen space that is available to display a picture, video or working space, without obstruction from the bezel or other aspects of the unit's design. The main measurements for display devices are width, height, total ...
