Display
Display diagonal Size of the display for this product, measured diagonally, usually in inches.	86.7 cm (34.1")
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.	3440 x 1440 pixels
HD type Type of supported High Definition (e.g. Full HD, 4K Ultra HD).	Wide Quad HD
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.	21:9
Display technology The technology used in the display e.g. plasma, LED.	LCD
Panel type	IPS
Backlight type	LED
Touchscreen A screen of a laptop, smartphone, etc., that responds to touch so you can control the interface using your fingers.
Display brightness (typical) Display brightness, measured by its Luminance, presented as a figure in candela per square meter (cd/m2). Typical brightness ratings for monitors range from 250 to 350 cd/m2 with a target value of between 80 to 120 cd/m2 being suitable for most displays in a normal viewing environment.	300 cd/m²
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
