Display-only TV Sets – (a.k.a. Monitor) - In this scenario, the TV receiver that’s used for reception and decoding of the signal, is not built into the TV set. This is a term used more frequently concerning HDTV as a HDTV receiver can come in the form of the TV provider's set-top box. If you have an HDTV receiver already, generally all you would need is an HDTV monitor.
