Optoma EW556 3D Projector with DLP Technology

Indicates how many audio input connectors are available on the product, such as 3.5 mm jacks, mini‑jacks or optical inputs. The value is a simple integer representing the total count of these ports, regardless of their specific type or version.

The amount of light emitted by a display or projector, expressed in lumens (cd/m² for luminance). It indicates how bright the screen will appear under typical viewing conditions.

The colour or combination of colours that a product’s outer shell or enclosure is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the case for consumers.

The contrast ratio is the proportion between the brightest and darkest luminance a display can produce, expressed as a simple ratio such as 1000:1. It indicates how well a screen can differentiate light from dark areas, affecting image clarity and color depth.

The linear measurement of an object from front to back or top to bottom, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the item is and can be used for fitting, compatibility, or spatial planning.

The type of display panel used in a visual device, such as LED‑backlit LCD, IPS, TN, VA, OLED, or AMOLED. It indicates the underlying technology that determines image quality, color accuracy, viewing angles, response time and power consumption.

The frequency of the alternating current supplied to a device, expressed in hertz (Hz). It indicates the acceptable operating range for the electrical mains that powers the product and ensures proper functionality and safety.

The range of alternating current voltage that the product accepts from its power source, expressed in volts (V). It indicates the minimum and maximum mains supply voltages compatible with the device across different regions.

Specifies the physical configuration or design of a product, such as ATX, Micro‑ATX, Mini‑ITX, tower, case with cover, etc. It describes how the device is built and what mounting or expansion options it supports.

The vertical dimension of a product measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and applies to any item where height is relevant, including books, electronics, furniture and other objects.

The highest pixel dimensions that a device can output or support, expressed as width by height (e.g., 1920x1080). It indicates the maximum resolution available for display content on the product.

The total count of distinct colours that a display can render, typically expressed in millions or billions. This figure reflects the colour depth and determines how smoothly gradients and subtle hues are reproduced on the screen.

The optical system used by a projector to generate an image, such as DLP, LCD, LED, or 3LCD. It determines how light is processed and projected onto the screen, influencing brightness, color accuracy, contrast, and overall visual performance.

The pixel dimensions of a display or image, expressed as width by height (e.g., 1920x1080). It indicates how many pixels are used to render the visual content and is commonly applied to monitors, TVs, projectors, laptops, smartphones, and other devices that output video.

The highest pixel dimensions that a device can output or support, expressed as width by height (e.g., 1920x1080). It indicates the maximum resolution available for visual content on the product and is commonly used for monitors, TVs, smartphones, cameras, and digital images.

The pixel dimensions that a product’s screen can output or support, expressed as width by height (e.g., 1920x1080). It indicates how many pixels are used to render visual content and is commonly applied to monitors, TVs, projectors, and other display devices.

The pixel dimensions of a display or image, expressed as width by height (e.g., 1920x1080). It indicates how many pixels are used to render the visual content and is commonly used for monitors, TVs, smartphones, cameras, and digital images.

Indicates whether a product includes a dedicated Kensington lock slot, which is a physical opening designed to accept a Kensington-style cable lock or similar locking mechanism for preventing unauthorized removal or theft of the device.

Indicates the type of audio system integrated into a speaker or audio device, such as stereo, mono, or an integrated sound system.

The proportion between the distance from a projector to its screen and the width of the projected image, expressed as a simple ratio such as 2:1 or 1.5:1. It indicates how far the projector must be placed to achieve a desired screen size and is useful for planning installation space.

The total count and type of VGA input ports available on the device, expressed as a quantity followed by the connector name (e.g., "1 x 15-pin D-sub"). This attribute indicates how many VGA connections the product supports.

Specifies the type of VGA output connector on a device, such as "1 x 15-pin D-Sub" or "1 x VGA Out". This attribute indicates the physical connector used for video output and is applicable to projectors, docking stations, document cameras, and other electronic equipment that provide a VGA interface.

The horizontal measurement of a product, expressed in a linear unit such as millimetres or inches. It indicates how wide the item is from one side to the other and is used for sizing, fitting, and compatibility purposes.
