What is HDTV?
HDTV (High-definition television) is a new system of television that improves both production and reception of broadcasts for a picture quality up to 10 times better than standard definition. HDTV features increased lines of resolution and an improved aspect ratio (relationship of width:height): 16:9 as opposed to the 4:3 ratio of conventional screens.

Although many devices support a native resolution of 1280*720 or more, some cannot accept a 720p or 1080i signal at 50Hz and require that the frequency be increased to 60Hz, which usually involves using a scaler.
