    Yes, just select Movie Plus or Progressive Scan from the Digital Options menu

    Pixel Plus 2 is on all the time, but just operating at different levels.

    Full whack is PP2 on.
    Reduced processing, more natural colours - Movie Plus
    No pixel multiplication and fewer other processes - Progressive Scan.

    It is possible to run the 9986 with PP1 instead, but I don't know why you'd want to do that, so I'll not mention it again....sorry...bye.

    I did some experiments with a static picture displayed from the PC (via VGA cable).
    The 3 different levels of digital processing show some difference, but some artifacts of threshold processing remain visible in every level.
    Interestingly enough, when you select the "Pixel Plus 2 demo" screen, the left part of the screen (where it says "off") is free from artifacts.
    However, I have seen no method of selecting this mode for the full screen.

    I should say the difference is only visible with a static picture which has large evenly coloured areas and sharp lines between them. On normal TV content it is difficult to show.

    First time that I looked at a 9986 last June I viewed the PP2 demo screen. I put down PP2 as a negative on my shortlist.

    It seems like its a marmite function.

    Listen guys, you really wouldn't want to turn PP2 off completely. The picture on poorer signals completely falls to bits without it.

    I'm watching ER right now on C4. With the PP2 off that side of the screen shows the following flaws:
    Yellow whites.
    Juddery motion.
    Blurry picture generally.
    Grain.
    Aliasing.

    On the plus side no PP2 with a good signal does look smoother, but still suffers from 'dirty' colours and whites. (I can hear the Washing Powder jokes already!) Setting the PP2 to Progressive Scan has a similar effect, but keeps the whites Whiter! Movie Plus is my favourite - slightly softer edges and better colours. PP2 has its place, with the really ropey stuff...truly Biological!

    The effect depends on the source material. From analog PAL it works fine in its default settings, but when the source is MPEG it tends to amplify any blocking in the image, giving the result you describe.
    There is a "sharpness" setting that can be reduced to overcome this.
    (unfortunately it is not saved independently for each source, like screen size... however it is saved separately for DVI)

    What are the differences between pp1 and pp2. I am thinking of getting a 9976 and would like to know if pp1 is worth it or not. Does it have the same modes as pp2?
