Display
Display diagonal Size of the display for this product, measured diagonally, usually in inches.	101.6 cm (40")
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.	5120 x 2160 pixels
