Is High-Definition in Wide-Screen only?

Need to know, are all high-definition televisions in widescreen? Can there be a regular 4:3 television that supports hi-def signals?

1. no

3. no u can get small hdtvs for about $500
4. High Definition calls for the 16:9 format.
5. The short answer to your question is NO. regular television SD ( Standard Display) supports only 480 horizontal lines maximum. High Def is a minimum of 720 with a maximum of 1080 horizontal lines.
6. No not all in wide screen format. Some old TV that HD ready it's still in 4:3, but when you watch HD-signal which is 16:9 the picture will be cut off in top and bottom.
