HD full form is High Definition — referring to video and image resolution that is significantly higher than standard definition (SD). In technology, HD commonly means 720p (1280×720 pixels) or 1080p (1920×1080 pixels) resolution. In computing, HD also stands for Hard Disk. In medicine, HD stands for Hemodialysis.
HD full form = High Definition (video/display).
HD resolution: 720p (1280×720) or 1080p Full HD (1920×1080).
HD also = Hard Disk/Hard Drive (HDD) in computing.
HD also = Hemodialysis (kidney dialysis treatment) in medicine.
Higher than HD: Full HD (1080p), 4K (2160p), 8K (4320p).
SD (Standard Definition) = 480p — lower quality than HD.
Full Form 1: High Definition (Video/Display) • HD = High Definition — higher resolution video/image quality • HD resolution: 720p (1280×720 pixels) or 1080p Full HD (1920×1080) • Compared to SD (Standard Definition): 480p or lower • Common in: HD TV, HD cameras, YouTube video quality, streaming
