I am new to HDTV. I have a direct view CRT widescreen HDTV monitor (RCA D34W20). According to the specs sheet, my HDTV has 910 lines of horizontal resolution. I'd like to know how to translate this into HDTV format. Does this mean that it has 1618 vertical lines or horizontal dots (910x16/9=1618) or simply 910 lines or dots? How many lines of horizontal resolution for 910 vertical lines or horizontal dots? Also, how many scan lines or vertical dots are there according to the ATSC standard and how many for typical direct view CRT HDTVs? Thanks.
