Standard Definition (SD), High Definition (HD), Full High Definition (FHD) and Ultra High definition (UHD) refer to the clarity or resolution of a moving image via a television, display device or monitor. Definition is measured as width x height in pixels.
When holding an event, definition is an important consideration to ensure a good quality viewer experience. But how much definition do you need? Let’s look at the options.
SD
Standard Definition refers to the image resolution of most older televisions and DVDs which are usually 720×576 or 720×480.
HD or FHD
High Definition refers to the image resolution of newer televisions, HDTV and Blu-Ray. There are three major formats of HD – 720p (1280×720), 1080i (1920×1080) and 1080p (1920×1080). 1080i and 1080p are often marketed as FHD to highlight the improved clarity over 720p.
UHD
Ultra high definition refers to the image resolution of the very latest higher definition screens and is usually 4K (3840×2160) and 8K (7680×4320).
So which should you choose? One consideration is the quality of the input which can limit your options. If, for example, you are transmitting SD video, using a FHD television or screen isn’t going to improve upon the clarity.
Other things to keep in mind include how many screens you’ll have at your event and how far away from the screens your audiences will be. Speak to your AV provider to get expert advice on what will work best for your event.
