i have been contemplating the use of a LCD monitor as a Television but i have not really seen this done anywhere. by monitor i mean the kind generally sold for use with computers as opposed to a TV without a built in tuner. is there any reason this practice is uncommon? PC LCD's have very good resolutions and refresh rates (down to 8ms) and it would seem would make great TV's coupled with a HD set top box. also are LCD's natively progressive? i only see some advertised as such so am unsure. thanks.
