Un autre test (en anglais) que je partage entièrement : http://www.blu-ray.com/movies/Avatar-Bl ... view/7847/

Reference quality. Demo worthy. Grade-A eye candy. Whatever you want to call it, Avatar on Blu-ray is the kind of material that not only sells discs, it sells entire home theater systems. It's a visual showpiece from start to finish, and if the big box stores start playing Avatar on their floor displays—maybe they already are—I guarantee they'll see a spike in HDTV and Blu-ray player sales. I don't want to gush. I'm not a gusher by nature. But put quite simply, Avatar's 1080p/AVC-encoded transfer—framed in James Cameron's preferred 1.78:1 aspect ratio, filling up almost the entirety of a 50 GB disc, and coasting along at an extremely high bit rate—is nothing short of superlative in nearly every objectively measurable or subjectively eye-balled category. Clarity is astounding. The texture work and resolve of the various CGI creations shows a degree of fine detail that's unprecedented. The skin of the Na'vi is defined and has a palpable presence, keenly reflecting light and glistening with perspiration. You can even make out each bead on the high priestesses' intricate beadwork shawl. Live action elements are just as well attributed. In establishing shots of the environment, individual blades of grass can be seen bending in the wind of a helicopter's blades. The human actors are crisp and, with very few exceptions, blend in seamlessly with the gorgeous digital backgrounds.
Color is nothing if not eye-popping, with deep jungle greens, phosphorescent purples, bright orange bursts of fire, and, of course, the Na'vi's Smurf blue, all contrasted against the bleak fluorescence and gunmetal grays of the human military base. Just as impressive are the deep black levels and right-on contrast, which sculpt out an image that's frequently so dimensional that you really don't miss the 3D. My notes while watching the film looked something like this: "This is the most vivid, immersive scene I've seen yet on Blu-ray." A few minutes pass. "Wait, no, this is the most vivid, immersive scene I've seen." And so on, with the film constantly one-upping itself. On the technical side of things, the encode is flawless, with no compression-related concerns whatsoever and practically zero noise. My expectations were certainly surpassed. Like it did in the theaters with 3D, Avatar has just raised the bar for home video on Blu-ray.
