Yes, 2D->3D using the 3D-goggles (this is the only way i can get it to run 120hz, 60fps per eye, half the frames being faked for 3D effect). I think it uses 4:4:4, at least text and images look normal and crisp and reviews say so. I recall reading some review stating 4:2:2, but the official panasonic product page says: 1080p pure direct "Offering colours that are faithful to the original 1080 content, Pure Direct increases the transmission efficency of high quality 30 Bit YUV 4:4:4 content. YUV refers to the three types of data the TV receives; the more data transmitted and displayed the higher the quality picture. Y = Brightness UV = Colour Signal YUV = Image produced *VT60, WT60, DT60" "The VT60 also adds a 1080p Pure Direct mode that enables support of a 4:4:4" So, afaik, it supports 4:4:4. I have also set hdmi range full both in nvidia panel and in the monitor's settings, 1080p Pure Direct on. I could definitely be wrong though, i searched for some tests, and the best thing i found was to create a colored background in paint, and draw single pixel wide lines/scribble on it. Blue on red looked normal, red on blue looked a touch odd, like vertical lines were a touch brighter red than horizontal lines, but every pixel was certainly displayed as red. Black on white/white on black looks normal. I don't know much about chroma subsampling, and am not very picky with colors unless its quite far off.. such as IPS/TN being completely unable to display black.. (I see color errors briefly, after a minute or so it fades away due to adjusting to it, i guess).
