4K refers to a monitor resolution that is roughly 4,000 pixels wide, sometimes also called 2160p because of the number of horizontal lines. Other well-known resolutions are 720p and 1080p that have less than 25% of the pixels found in 4K.
• 1080p resolution (FHD or Full HD) is 1920 x 1080 lines = 2 million pixels
• 1440p resolution (QHD or Quad HD) is 2560 x 1440 = 3.6 million pixels
• 2160p resolution (4K, UHD, or Ultra HD) is 3840 x 2160 = 8.3 million pixels
4K and UHD (which stands for ultra-high-definition) simply refer to the resolution of the screen, which affects the sharpness of the image. On the other hand, HDR (high-dynamic-range) enhances the contrast ratio, which is the luminance difference between the brightest part and darkest part of one image.
With its larger contrast ratio, HDR reveals more details in very bright and dark scenes, delivering pristinely bright whites, superbly deep blacks, and intensely saturated and vibrant colours. All this results in HDR images that appear more realistic and vividly stand out.
HDR enhances the brightness, contrast, colour, and detail performance of displays independently from the monitor’s resolution. HD, FHD, QHD, and 4K UHD can all support HDR, but only when they meet the minimum technical specifications in terms of contrast ratio and brightness according to HDR standards.
*HDR and B.I.+ are available in some models, please see product specifications before purchase.
