Maximum power consumption
The highest electrical power that a device can draw or consume during operation, expressed in watts (W). It represents the peak energy usage of the product and is useful for estimating maximum power requirements, comparing efficiency across similar devices, and ensuring compatibility with power supplies.
127 W
Native aspect ratio
The proportion between the width and height of a screen or image, expressed as two numbers separated by a colon (e.g., 16:9). It indicates whether content is designed for widescreen, square, or other aspect ratios and helps users match devices to their media formats.
16:9
Operating relative humidity
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.
10 - 80 %
Panel mounting interface
The pair of horizontal and vertical dimensions in millimetres that a product supports for VESA mounting (e.g., "100 × 100 mm"). This value indicates the exact hole spacing required by a mounting bracket to secure the device. It is used for monitors, TVs, projectors and other display equipment that can be wall‑mounted or attached to stands.
