2.17 m (85.6")
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.

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
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'.
350 cd/m²
Contrast ratio (typical)
The difference in light intensity between the brightest white and the darkest black.
1200:1
Pixel pitch
This is the parameter of a picture tube, which specifies the shortest distance between two dots of the same colour. The principle is: the smaller the dot pitch, the better sharpness of image.

Backlight type
LED
LED backlight
A backlight is a form of illumination used in liquid crystal displays (LCDs). One type of backlight is made by LEDs, which can be either white or RGB (red green blue). White LEDs are used most often in notebooks and desktop screens, and in virtually all mobile LCD screens. RGB LEDs for backlighting are found in high-end color proofing displays such as HP DreamColor LP2480zx monitor or selected HP EliteBook notebooks, as well as newer consumer grade displays such as Dell's Studio series laptops which have an optional RGB LED display.
