November 4, 2023 by Harry Ford HD and FHD are two terms often used to discuss the resolution of images and videos. HD means "High Definition," and "FHD" means "Full High Definition." These resolutions are used in many devices, like TVs, computer monitors, and cell phones. However, what do these terms exactly mean, and how do they differ? 1080p (1920 × 1080 progressively displayed pixels; also known as Full HD or FHD, and BT.709) is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; [1] the p stands for progressive scan, i.e. non- interlaced. FHD stands for Full HD or Full High Definition and refers to 1080p video resolution, which is 1,920-pixel columns by 1,080-pixel rows. That equates to 2,073,600 total pixels or about 2 megapixels. The "p" in 1080p refers to progressive scanning, which means each row of pixels is scanned in sequential order. These days when we say HD we're talking about what gets called 'Full HD', a resolution which measures 1,920 x 1,080 pixels, often called 1080p. This display resolution is common on Smart TVs .
