    Amazed you havent seen it before the V20s I had were awful, this years are far better.

    Using IFC helped my V20 and GT30.

    I had 42PX80 which is 720 p set. It being non-3D, non HD and being 42" doesnt show any DFC and was non-existent to me. Only with ST60 i started seeing it. Is it so that putting IFC to min or med will improve the DFC but will start to show video effect on movies?

    I have px80 but when I went to demo VT / GT 60 I was disappointed to see unusual quirks like DFC on them, the pictures don't seem clean like px80. Samsung F8500 fared better.

    IFC on min will not add visible issues like artifacts or video like motion.

    Disagree the reason you see more on the other sets is due to the less clean image on the PX80.
    I went from a PX80 to a V20 and it was like a vale had been lifted, the V20 had a far cleaner image, sadly a cleaner image means issues like DFC are more evident. The Samsungs have more dither so again the issue isn't as obvious on those.

    It seems that i see this only on some SD channels and others i dont see it. If the DFC is due to the panel, shouldnt i see it on every channel?

    Yes its basically always there but the content makes a huge difference, some programs are simply awful low bit rate content will look bad on any set pretty much, Being less 'noisy' Panasonic sets can reviel the issue more, processing effects things too, Samsung are better as far as Im aware.

    I've noticed too, but in my case I think is do to with me trying to find the correct skin tone, right now besides DFC sometimes faces has a brightness in them.

    The best thing you can do is use test patterns, a meter if you can or get a calibration done.
    Hard to judge what skin should look like, given different lighting on sets, peoples skin varying greatly and artistic differences in the look of films.

    Playing all Content in 60Hz instead of 24 Hz helps a lot against DFC :)

    Agree. Never had DFC in my old PX80 but now just upgraded to latest GT60 and DFC is frequently seen, especially in faces, which are usually not defined, unless in a studio. Don't get me wrong the colours, black level and brightness are way better in the GT but they were no DFC in my old set.

    I see it too. But with dfc set to medium it doesn't seem to bother so much. But, i understand that dfc is most visible with 50hz (cable TV) and not with 60hz (media player on hdmi). Am i right?

    Nope it depends on bitrate, you're talking about the 50hz bug, thats like a double image like effect.

    DFC and Line Bleed is worse on my latest gen Panasonic than my older PX80 too.

    Things have gone backwards imo.

    + The latest LEDs this year are so good you do wonder how long Plasma has left is basics like this have still not been fixed. (this also includes, poor whites, buzzing, posterization, flicker and uniformity issues as well as the DFC and bleeding)

    i used to have a "working" VT50. hated it so much !!!! this was one of the reasons. drove me crazy. so distracting. you maybe able to get a good picture from some of these plasmas, but it comes at too high a price for me.

    I have both the ST60 and PX80 at my place, but in different floors. I have to say that the whites and blacks on my ST60 is way better than my PX80. Ok, there are some DFC problems and 50Hz bug but then its definitley not going backwards. ST60 is just having a much cleaner image and with it comes issues that is more visible. I am enjoying my ST60 much more as time passes by. I would compare a bottle of single malt whiskey to Panasonic plasma, always getting better with age. :thumbsup:

    I have had last years Samsung LCD which went back in 2 record days, swore since then never to look back at an LCD. Hello OLED!

    I kind of agree. My GT60 can produce some stunning images, blu rays look incredible, ps3 better than ever, but it can also produce some of the worst looking pictures using sky HD, to the point where i want to change channel.

    In all honesty I probably would buy this TV again. If it broke and i got a refund Id still go and get another, the good definitely outweighs the bad.

    Interestingly, when 50 and 60 series came out, many reviews were claiming there was much less dithering, that 50Hz 'bug' is solved etc
    Some people here claiming just the opposite
    Checked ST60 last week in the store and - my impression is that everything is about the same as in 30 series, except that black level is probably better, which wasn't possible to observe there .. despite big promises by Panasonic with FFD and other marketing tricks ...

    The 'bug' isn't solved this year for those of us sensitive to it. However it does appear to affect only neo-PDPs, i.e. not the PX80, etc..

    It will never be entirely resolved, because there is a "600 Hz bug" in the background :D So on other plasmas it just looks a bit different

    It's damn annoying. I would go with LED but with most having DSE (which my 8 year LCD suffers with permanently and pretty badly) and most having only passive 3D I've no choice but to hope it isn't as bad as it's made out!!!

    At a risk of going off-topic, I think that Samsung PDPs better hide such motion artefacts and note that this year's high-end models go plenty dark.

    Yes, we were also discussing that. It's just that those 12 subfields are probably arranged a bit differently than on Panasonic, so brightest subfields are not that apart, - but picture is always composed of subfield and when the object moves, in our eyes edges decompose into those subfields (as I simulated in some other threads) causing problems this way or another

    Don't the newer Panasonics have a higher drive frequency?

    I haven't seen anything DFC-like on the VT65. But perhaps I have just been lucky so far - I haven't watched Come Dine With Me.
