I have the P65-C1 and have it connected up to an HTPC.. I can confirm it does a pseudo 4:4:4, like the RTINGS review talks about.
We have concluded that all current Vizio TVs that we have reviewed do not display 4:4:4, but something quite close. This is due to the TV inputs accepting 4:4:4 but the image is not as clear as 4:4:4 on other TVs. This is most obvious when looking at the test pattern from very close.
.. So yes, text is completely legible but not as pixel perfect clear as a set that does true 4:4:4, which my old Samsung did. Without being a fanboy, the set is so overwhelmingly good at everything else, it was an easy decision to keep.
Not a deal breaker (I'm very picky) but I don't know if I would want to use this as my primary monitor, i.e. if I was sitting super close to the screen. One other thing to keep in mind, I'm making my 4:4:4 comparisons at 1080p, my current video card does not do 2160p.
