1080p resolution, often referred to as Full HD, is a display resolution that offers a pixel count of 1920 by 1080. The “1080” refers to the number of vertical lines (or rows of pixels), while the “p” stands for progressive scan, meaning the image is drawn in a single pass, from top to bottom. This results in a smoother image compared to interlaced video, where the image is drawn in two passes, which can cause a flickering effect. The pixel dimensions of 1920×1080 provide a wide aspect ratio of 16:9, which is ideal for modern widescreen displays.
When compared to 720p, which has 1280 by 720 pixels, 1080p offers a significant upgrade in detail and clarity. While 720p is still considered high definition, 1080p provides a more immersive viewing experience, especially on larger screens. On the other hand, 4K resolution, which has 3840 by 2160 pixels, is four times the resolution of 1080p, offering even greater detail but also requiring more bandwidth and storage.
