Knowing the standard of your HDTV helps your devices communicate with one another.
Different HDTV technologies will have different resolutions, which will dictate whether your TV is 720p or 1080i. But what do all the letters and numbers mean, and how will they affect the quality of your picture?
Resolution refers to how many pixels will make up your TV screen, and is important in dictating the quality of a high definition TV. The higher the resolution, the better the quality of your image will be.
'Interlaced' resolution verses 'Progressive' resolution also different, with progressive resolution better at conveying high definition pictures and those images that are fast moving.
The following table dictates the common technologies and what resolutions they operate by.
