Euro version, because, as I stated, I'm in Switzerland, and I'm not silly enough to buy a TV overseas.
And, as I said too, I bought the ZT60, so nothing for me to worry about here.
Thanks for your concerns, but I think after 5 years and 16200 hours of computer use on my panel, I know how to deal with burn-in.
Never have I any "fixed" component on the screen, that means no still menu bar, nothing. I also have a small script which "erases" the small burn-ins that may occur in a day to day basis. Everytime I leave the computer, that script puts the TV in a 15 minutes timer, and while doing so, starts a sort of fullscreen slideshow, composed of pictures with only one color in it, and a 30 seconds white noise video. They alternate every second for 15 minutes.
I have no way of knowing if this has actually had any good impact on the screen, but I have never seen any image retention whatsoever...
