    After looking at the website www.progressivescan.co.uk it seems that progressive scan offers a much better picture. Do you think CRT TV's will eventually start offering Progressive Scan? How long do you reckon before we start seeing some nice range of PS TV's?
    Does Progressive Scan facility put the price up a lot, or will it only cost a few hundred quid extra?

    Thanks

    It can do if done properly, but there are other issues to solve, such as many consumers not liking 50Hz flicker.

    Yes; not because it is in high demand but because the technology will naturally carry over from American and Japanese HDTV models. Progressive scanning at least 480lines @60Hz is part of the DTV/HDTV spec in the USA so that feature will become widely available on most half decent TVs in the USA fairly soon. However, here in the UK/Europe 50Hz flicker and 25Hz line flicker is considered the major image artifact to eliminate so we have had progress in 100Hz scanning technologies which scan at the same rate as progressive TVs but are still interlaced although they do mostly perform interlaced to progressive proccesing to achieve the extra 50 fields per second. 100Hz technology has brought flicker free and stable images along with other digital manipulation features so progressive scanning at 50Hz is not considered particularly desirable/marketable etc.

    BTW, I am perfectly aware of the fact that some 100Hz processing and other digital features are poor quality and dubious, so please don't turn this thread into a slagging match over 50Hz vs 100Hz.

    Should see the range increase steadily over the coming couple of years, hard to say how many models as I explained above the feature is not a priority for UK/European CE manufacturers.

    As for the expense, the answer is no, not a lot of difference compared with current large screen 100Hz TVs because they use de-interlacers and the same scanning rate anyway. However, some manufacturers are testing the feasibility of 100Hz progressive displays, but so far they do cost a lot more to produce and are not yet suitable for the domestic market.
