Even using 3:2 pulldown on the Panasonic (which yes, you must do because the 48hz mode DOES have flicker), the overall movie experience on the Panny is still going to be MUCH superior to 99% of the 120hz lcds out there running in 5:5 mode. Even with some mild judder from 3:2 pulldown (which most people won't notice), the panny will still produce far superior overall motion quality, deeper blacks, superior saturation over most 120hz lcds and excellent colour accuracy to boot (One main advantage over the z85). Most 120hz lcds still can only produce 600 vertical lines of motion resolution. Even the average plasma can produce 900 equivalent lines of motion resolution.
There is no question that the Panny z800 is one of the absolute best HDTVS out there for movie watching, and IMO better than 99% of 120hz lcds for sports as well, despite the necessity to use 3:2 pulldown mode for movies on the Panny. Read some reviews if you must. Check out the CNET review perhaps. That shows how important this 5:5 pulldown is right there if one of the best movie tvs around which receives excellent reviews all over the place, still must do 3:2 pulldown.
Truth be told, its best to take a look at both a 120 hertz and 60 hertz lcd side by side and see if YOU the buyer see a worthy difference.
I totally agree with this, only the "difference" might not necessarily be percieved as "better". The main difference I percieve for instance on most 120hz lcds (with exception to the top of the line ones), over 60hz models, is the effect of the frame interpolation, which IMO, on most 120hz lcds, does more harm than good for overall viewing in most instances other than sports and sometimes video games. Not just because of the creepyness of them being overaly smooth, but the artifacting and enhanced background detail which was not meant to be seen by movie producers, sometimes revealing props, taking away a sense of spaciousness, and completely altering the way the movie was intended to be seen. I will not argue however that a 120hz lcd using motion interplatoin looks superior for sports than a 60hz lcd. Because IMO it does, but still not as good and natural and a good plasma.
Since this is an LCD section and not plasma, I will clearify my point:
Although most 120hz lcds offer other improvements other than refresh and motion interpolation, weither you need it or not, or even like it or percieve it as better is up to the individual, and since the original purpose of 120hz originally was to improve motoin quality by reducing blur, it was worth noting that one can get FAR superior overall motion quality from a plasma over 120hz lcds for the price, while still mainting the vision movie producers intended. Do you NEED 120hz? Well if you care enough about motion to think so, it doesn't make sense to go lcd over plasma anyway in most cases especially considering a price to performance ratio.
