DynaScan DS491LT4 48.5" High Brightness LCD

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

Indicates the total count of left‑and‑right (L/R) audio output ports available on a product, such as headphone jacks or speaker connectors that provide stereo sound. The value is an integer representing how many separate L/R pairs can be used to connect external audio devices.

The colour or combination of colours that a product 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 item for consumers.

List of the memory card types that a device can read or write, such as MicroSD (TransFlash), SD, MMC, CompactFlash, and others. Each value represents a format that the device’s slot or reader supports for storage expansion.

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 visual content and is commonly used for monitors, TVs, smartphones, cameras, and digital images.

The type of visual panel or display technology used in a product, such as LCD, LED, OLED, TFT, IPS, AMOLED, or analog. It indicates the underlying technology that determines image quality, color reproduction, power consumption and suitability for different use cases.

Represents how many DVI‑D connectors are present on the product. The value is a simple integer indicating the total count of DVI‑D ports, regardless of version or configuration.

Indicates whether the product’s graphics adapter supports the OpenGL standard, which determines its ability to render 3D graphics and run applications that rely on this API.

The total amount of internal memory available in a device, expressed as a data size such as megabytes (MB) or gigabytes (GB). It indicates how much information the component can hold for active processes and affects multitasking performance.

The total amount of digital storage available inside a device for holding files, applications and other data. It is expressed as a numeric value with an appropriate unit such as GB, MB or TB, allowing users to compare how much information the device can store.

The amount of internal memory reserved for a processor’s L2 cache, expressed as a pair of values: the number of banks and the capacity per bank (e.g., "4 x 256 KB"). This format allows specification of both the count of cache banks and the capacity of each bank, which together determine the total L2 cache available to the CPU.

The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

The total duration that a product or device operates before requiring recharge, maintenance, or rest. It is expressed in standard time units such as hours, minutes, or days and applies to appliances, electronics, and media items.

Indicates the preferred or supported orientation of a product, such as landscape, portrait, horizontal/vertical, or other directional settings. This attribute helps users understand how the device can be positioned for optimal use.

A list of natural languages that can be displayed on the screen‑on‑display (OSD) interface of a device, such as a monitor or TV. Each entry represents a language option available for menu navigation, subtitles, and other on‑screen text.

A list of the positions or mounting options where a product can be installed, such as indoor, outdoor, wall, desk, floor, ceiling, or universal. Each value represents a distinct placement scenario that the device supports.

The total number of physical processing units in a single central processing unit (CPU). This value indicates how many independent tasks the CPU can handle simultaneously, influencing multitasking and parallel performance.

The processor family identifies the group or series of CPU models that share a common architecture, design, and performance characteristics. It helps users compare processors across brands and generations by indicating the underlying technology used in the chip.

The fundamental operating frequency of a processor, expressed in hertz (Hz). It indicates the speed at which the CPU runs under normal conditions and is typically reported in gigahertz (GHz) or megahertz (MHz). This value helps users compare performance potential across different models.

The range of temperatures in which a device can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

Indicates the dimensions of VESA mounting patterns supported by the product, expressed as pairs of horizontal and vertical measurements in millimetres (e.g., "100×100 mm"). The value may be a single pattern or a comma‑separated list of multiple compatible sizes.

A list of video file formats that the product can play or record, including both the compression codec and the file extension. Each value represents a valid combination of technology and format supported by the device’s hardware or software.
