| Display | |
| Display diagonal Size of the display for this product, measured diagonally, usually in inches. | 139.7 cm (55") |
| Display technology The technology used in the display e.g. plasma, LED. | LED |
| Display resolution The number of distinct pixels in each dimension that can be displayed. It is usually quoted as width × height, with the units in pixels: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels. The higher the number of pixels, the sharper the image. | 3840 x 2160 pixels |
| Display brightness Brightness is the amount of radiating light emitted from the screen. The brightness rating is measured in candellas per square meter, commonly known as 'nits'. | 700 cd/m² |
| HD type Type of supported High Definition (e.g. Full HD, 4K Ultra HD). | 4K Ultra HD |
| Touchscreen A screen of a laptop, smartphone, etc., that responds to touch so you can control the interface using your fingers. |
 |
| 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 |
| Response time The response time is the time difference between the moment that a source (for example a video card) sends a signal and that equipment (for example a monitor) receives or display the signal. (Used abbreviations: R/F = Rise and Fall.) | 8 ms |
| Contrast ratio (typical) The difference in light intensity between the brightest white and the darkest black. | 1000:1 |
| Viewing angle, horizontal Maximum horizontal angle at which a display can be viewed with acceptable visual performance. | 178° |
| Viewing angle, vertical Maximum vertical angle at which a display can be viewed with acceptable visual performance. | 178° |
| Display number of colours | 1.07 billion colours |
| Panel life The length of time that the panel can be used for. | 30000 h |
| Ports & interfaces | |
| 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.
