Will an HD receiver work on a non-HD television?

Almost all HD sources, whether they are receivers or disc players, will have a standard definition output. They will all have an HDMI connector to provide the HD output as well. Receivers with an SD output will deliver a signal that is standard definition regardless of the original source resolution. Be aware that the quality will ALWAYS be standard definition when viewed on a standard definition television. It is still worthwhile to purchase an HD receiver now because the HD quality will be available as soon as an HD television is added to the system. HD televisions cost little more than SD televisions, so the next TV purchase will very likely be an HD model. It is important to check that a receiver has the SD output before buying one. Although most will have SD outputs, don't get caught out by buying one of the few models that is HD only.
