Motion blur - is there a difference when using HD as opposed to SD?

    Hi all,

    We have a Sony Bravia KDL 40w4500 (100hz, whatever that means) which we use with bog standard sky plus. I've noticed that when watching tennis or snooker, the amount of motion blur (the ball leaves a trail on the screen, or you see two balls moving) is quite bad, regardless of whether motion flow is turned on or not.

    We are having HD installed next week and I'm just wondering if that will make things any better, being through a HDMI cable and all, or whether the refresh rate (I think that's the reason) is simply not good enough to have perfect-ish picture?

    Ta.

    Unfortunately it's inherent in the LCD technology. Older sets like yours suffer from it more so than newer ones, but they still have it.

    If you wanted to, plasma is the way to go for natural motion on screen.

    Agreed, I have a NeoPDP 600Hz Panasonic Plasma and and there is no blur, it is the 2009 Model but is brilliant.

    HD will make it better. We watch a lot of rugby and it was very noticeable. Watched the Six Nations on the BBC in HD and it was much, much better. Like yours ours is quite an old (relatively) HDTV.

    The problem is there isn't much on in HD.

    Yeah I notice it a bit too on non HD channels (sky hd box, samsung 1080p lcd tv)

    Picture is perfect however on the HD channels.

    There is ZERO inherent difference between HD and SD. Some HDTVs may process SD poorly.

    Nor is it anything to do with Plasma vs LCD. At this stage a Plasma has no advantages over LCD.

    This could be an inappropriate telecine setting on the TV for whatever input you are using. I got motion blur on my Pioneer TV until I changed "drive mode" to 2.
    If in doubt, switch mode to "cinema" or "movie", see it that helps.
    You could check if frame interpolation is on/off - that may impact it.
    Also, if there is any post-processing going on, like NR, switch them all off.

    I find that the Sky HD did improve the motion blur a little, aside from definition.
    I too have a Sony LCD, but I put it down to the Sky digitial data volume coming through.

    Have you tried a DVD of Tennis to see if it really is your LCD or actually SKY? If you try a DVD or even a BluRay and you'll see the real difference. One scene that is a good test is the David Attenborough Blue Planet series , particularly the Bait Ball scene where you have fast rotating fish.
