BenQ TK860i 4K UHD Home Cinema Projector

Projector
Smart projector
Screen size compatibility The different screen sizes which the device can work with.	2540 - 3810 mm (100 - 150")
Projection distance The maximum length at which an image can be projected.	2.5 - 3.8 m
Projector brightness	3300 ANSI lumens
Projection technology	DLP
Projector native resolution	2160p (3840x2160)
Contrast ratio (typical) The difference in light intensity between the brightest white and the darkest black.	50000:1
Native aspect ratio The aspect ratio is the ratio of the width of an image to its height. The native aspect ratio is the one which the projector/display is particularly designed for. Images shown in native aspect ratio will utilize the entire resolution of the display and achieve maximum brightness. Images shown in other than native aspect ratio will always have less resolution and less brightness than images shown in native aspect ratio.	16:9
Number of colours	1.07 billion colours
Horizontal scan range	15 - 135 kHz
Vertical scan range	23 - 120 Hz
Keystone correction, horizontal	-30 - 30°
Keystone correction, vertical	-30 - 30°

Light source
Light source type	Lamp
Service life of light source	4000 h
Service life of light source (economic mode)	15000 h

Lens system
Focus	Auto
Focal length range Measure of how strongly the system converges or diverges light. For an optical system in air, it is the distance over which initially collimated rays are brought to a focus. A system with a shorter focal length has greater optical power than one with a long focal length; that is, it bends the rays more strongly, bringing them to a focus in a shorter distance.For an optical system in air, the effective focal length (f and f′) gives the distance from the front and rear principal planes (H and H′) to the corresponding focal points (F and F′).	12 - 15.6 mm
Aperture range (F-F) Aperture range of the device's optics, expressed in f-stops.	1.9 - 2.47
Zoom capability The amount that the camera lens can zoom.
Zoom ratio Measures how much the camera can adjust its focus for distance shots. A 3x zoom ratio changes the camera's focal length by a factor of three, from 35 mm to 105 mm for example.	1.3:1
Throw ratio	1.13 ~ 1.47

Video
Full HD Full High Definition (HD) means that a display supports a resolution of 1920 x 1080 pixel, and has a digital TV connection.

Microphone in The socket where a microphone is connected to the device.
Serial interface type	RS-232
S/PDIF out port S/PDIF (Sony/Philips Digital Interconnect Format) is a digital audio interconnect used in consumer audio equipment over relatively short distances. The signal is transmitted over either a coaxial cable with RCA connectors or a fibre optic cable with TOSLINK connectors.
HDMI ports quantity The number of sockets (ports) for HDMI connections. HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transferring uncompressed video data and compressed/uncompressed digital audio data from a HDMI-compliant device ("the source device") to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for existing analog video standards.	3
DVI port Digital Visual Interface (DVI) is a video display interface to connect a video source to a display device, such as a computer monitor.
AC (power) in
Audio Return Channel (ARC)
