4K resolution
This resolution is used mainly in digital cinema production, and has a total of 8,847,360 pixels with an aspect ratio 256135 (≈1910). It was standardized as the resolution of the 4K container format defined by Digital Cinema Initiatives in the Digital Cinema System Specification, and is the native resolution of all DCI-compliant 4K digital projectors and monitors. The DCI specification allows several different resolutions for the content inside the container, depending on the desired aspect ratio. The allowed resolutions are defined in SMPTE 428-1: The DCI 4K standard has twice the horizontal and vertical resolution of DCI 2K (), with four times as many pixels overall.
Phantom (UAV)
The 4K was released in early 2016. Although both the controller and the aircraft appear to look similar to the Phantom 3 Advanced/Professional, the system is very much like the Phantom 3 Standard in that it uses 5.8 ghz for control and uses a 2.4 ghz wifi signal for FPV and telemetery. The range is slightly improved. The controller lacks hdmi / usb ports. The aircraft includes the Visual Positioning System module seen on the Professional/Advanced models.
