Projector
Supported aspect ratios The aspect ratio is the ratio of the width of an image to its height. The supported aspect ratios are the aspect ratios that can be shown by the device.	16:9
Smart projector
Screen size compatibility The different screen sizes which the device can work with.	2032 - 3048 mm (80 - 120")
Projector brightness	2500 ANSI lumens
Contrast enhancer
Projection technology	DLP
Projector native resolution	UHD 4K (3840x2160)
Contrast ratio (typical) The difference in light intensity between the brightest white and the darkest black.	2000000:1
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

Lens system
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′).	10.55 - 13.7 mm
Aperture range (F-F) Aperture range of the device's optics, expressed in f-stops.	1.8 - 1.85
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 - 1.3
Vertical lens shift range	-5 - 5%
Offset	100%

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.
3D The device can be used with 3D technology.
Supported graphics resolutions The graphic resolutions that can be displayed by the device. The graphic resolution describes the width and height dimensions of a display, such as a computer monitor, measured in pixels.	640 x 480 (VGA), 3840 x 2160

VGA (D-Sub) ports quantity Number of VGA (D-Sub) ports (connecting interfaces) in the device. The VGA (D-Sub) connector is a 15 pin connector between a computer and a monitor. It was first introduced in 1987 by IBM.	1
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
