    Ok, I've done a search one this, but all the posts I've turned up seem to be talking about using a PC as the source going into the Loewe set. (Apologies if this particular question has been asked before, but I couldn't find an answer. Perhaps someone could run up a summary of Loewe's progresive scan abilities?)

    I'm looking at getting a Loewe set (duh!), although not until later on in the year (going to be pretty much skint for the next few months as I'm moving in with the gf and we need stuff like furniture).

    At the moment I'm looking at either an Aconda or the new Mimo. However, I also want a set which has progressive scan.

    Now as far as i can tell from Loewe's site, the Mimo & Aconda (or at least the 9381ZW) have some form of internal de-interlacing (Loewe's Digital Line Interpolation or DLI if I'm making the right assumptions), but that more than likely isn't going to be as good as an external unit.

    Now from what i understand, the Loewe VGA module accepts a progressive signal (and lots of people use a HTPC to connect to this). But what about non-PC sources?

    For example, if i were to feed my source units into, say, an IScan Pro and then into the VGA module, would this actually sync? If so, would this be a big improvement (i.e. worth the financial layout) on the sets own deinterlacing and other digital processing?

    Sorry - this won't help much - but have you thought about the Vitros as it's cheapr than the Aconda?

    Some people have discussed in this forum about it.
    This is what the German Customer Service Center says:

    It's possible, but if it really is beter is the question.
    In their own words:
    'Es ist richtig, dass sowohl der Q2400 als auch der Q2500 Aconda 93102 ZW progressive Signale über VGA (muß nachgerüstet werden) darstellen können, solange diese, wie beschrieben im Format RGB +H +V (VGA Standard) sind. ...
    Über die AV Buchsen des TV ist eine Verarbeitung von Progressive Scan Signalen nicht möglich, ...

    Die Darstellung über diesen Weg hat aber gravierende Nachteile, zum einen wird ein PAL Signal in dieser Form dann mit 50 Hz Bildwiederholfrequenz dargestellt, was zum bekannten Großflächenflimmern führt. Wegen dieses Großflächenflimmerns wurde ja die 100 Hz Technik erst eingeführt.
    Zum anderen sind in dieser Betriebsart keinerlei Bildverbessernde Funktionen des TV aktiv, da das Signal fast direkt an die Bildröhre weiter gegeben wird, ohne zuvor von der Elektronik verarbeitet worden zu sein. Dies betrifft die:
    - Bewegungsinterpolation DMI
    - Zeileninterpolation DLI
    - Rauschunterdrückung DNC
    - Reduktion des Zeilenflimmerns DLC
    - Kontrast optimierung DSC
    - Farbflankenversteilerung DTI
    - Digitaler Kammfilter
    - Schärfe kontroll System (SCS)

    Gleiches gilt auch für die Darstellung von NTSC Signalen über diesen Weg, wenn auch das Großflächenflimmern durch 60 Hz Bildwiederholfrequenz nicht mehr so stark wahrnehmbar sein dürfte.

    Die Summe all dieser Einschränkungen läßt den Schluß zu, dass die Bildqualität nicht der entspricht, die Sie beispielsweise von der Wiedergabe einer DVD über Scart gewohnt sind, auch wenn natürlich grundsätzlich das progressive Signal das bessere ist.'

    But I have not heard of read of anyone who really made use of a progressive DVD-player via a Loewe TV and tell comparative about the quality. Some people work with an external interlacer and then the question is: should I use the internal or an external interlacer?

    Unfortunately it doesn't pass the crucial GFAF (girlfriend acceptance factor). The gf's seen both and definitely dislkied the Virtos chassis.
