    Hi,.

    Does anyone know what improvements/differences the Sharp Aquos LC-30HV4E has over the LC-30HV2E model?

    Thanks for any info...

    I am not 100% sure. But the difference is internal scaler type.
    I think 2E had the first generation c-vic, and 4E has the 2nd generation c-vic II.

    Also, as far as US model goes, difference between 2U, and 4U (European 2E, and 4E euqivalent) is DVI/HDCP.

    So, would this improvement result in much difference in picture quality?

    Yes, the difference between c-vic, and c-vic II is quite big.
    But I'm not sure if 4E has the c-vic II or not.

    I've read on AVS forum, and one of them seems to own both, and he says the difference is not noticable. This probably mean that he doesn't have a clue, or 2E, and 4E both are about the same, and have old c-vic scaler which is bad.

    So what does the c-vic scaler do? Is it a third party designed chip?

    No, c-vic is Sharp's proprietary scaler. And what they do is scale. :)

    LCD, DLP, LCoS, and Plasma are fixed pannel devices. Which mean incoming signal (NTSC, PAL, HD) has to be deinterlaced(if source is interlaced), and scale to fit native resolution of the pannels. (native resolution of the pannel is 1280x768 in case of 30HV4E, and 2E).

    I used Sharp z9000 DLP projector for many month, and this has first generation c-vic scaler. Its performance was pretty bad.

    New Sharp z10000 has c-vic II which is far superior to the first one. It also has enough horsepower to do motion apative deinterlacing on 1080i sources, and it does it very well. (does 2:3 inverse-telecine on 1080i film-based sources as well.)

    So if 4E does have c-vic II inside, its performance would be miles better in terms of scaling, and deinterlacing specially with 1080i HD sources.

    Hi again,

    Did you ever find out if it does use the newer chip? I'm considering buying the HV4E model
