One of the greatest advantages HDTV (High Definition Television) enjoys over the standard TV is its resolution. More than a million pixels appear together on the screen at the same time to give you a sharper picture quality. Here we help you understand HDTV picture resolution better.
Instructions
1. Understand native resolution is the innate pixel capacity of your HDTV display or monitor. If the pixels in the incoming picture are more than the native resolution, your set will scale the picture down. The picture may lose some sharpness in this process. If the incoming picture has lesser pixels than the native resolution, your set will not be able to enhance the picture in any way.
2. Acquaint yourself with the source resolution. The main resolutions are 1080i, 720p and 1080p. 1080i has a pixel resolution of 1920 x 1080 but is not a progressive scan resolution. Several major networks, CBS, NBC, PBS, DiscoveryHD and Xbox 360, offer this resolution. 720p has a pixel resolution of 1,280 x 720, much less than that of 1080i, but is a progressive scan resolution, resulting in smooth images, which don't distort in motion. The major networks offering this resolution are ABC, ESPNHD and Fox.
3. Understand that 1080p is a relatively new resolution, which combines the goodness of both the above resolutions. It offers the pixel resolution of 1920 x 1080, along with the progressive scan picture quality. But the flipside with this resolution is the fact that no major network offers it. Though it promises to catch up in the future. Other than these three, there are lower resolutions like 480p and regular TV resolution, which do not offer quite the same quality.
4. Understand display resolution. The main HD display resolutions are 1080p, 768p, 720p and HDTV plasma. 1080p comes with a native resolution of 1920 x 1080 and is an emerging resolution. Though rare now, it is picking up momentum and has a promising future. This resolution is adopted by flat-panel LCD, DLP, LCD, LCoS projection and very high-end plasma TVs. 768p has a native resolution of 1366 x 768 and can be seen in flat-panel LCDs and 50-inch plasmas.
5. 720p has a native resolution of 1280 x 720. This display resolution is commonly found in rear-projection screens. It is adopted by DLP, LCD and LCoS projection. The HDTV plasma has a native resolution of 1024 x 768 and is the most common plasma resolution. It is found in 37 and 42 inch plasma TVs.
