AMD's Trinity-based laptop was the most impressive demo at the company's CES 2012 booth, but we couldn't pass up the chance to play Battlefield 3 across three nearly bezel-free screens on a pair of Radeon HD 7970s — especially when flanked by an additional pair of screens doing multipoint video conferencing. One of the little-known features that AMD added in the new Radeon HD 7000 series is Digital Discrete Multipoint Audio, or DDMA for short, which basically means you can assign audio, not just video, to a particular monitor, and always hear audio from the direction of the program it belongs to. In this case, the booms and bangs of Battlefield came from ahead, while the friendly AMD reps spoke to us on either side, though you could also theoretically use DDMA to send different video streams to entirely different rooms of your house. Witness our editor Vlad Savov succumb to the technology's charms (or a hail of virtual bullets, take your pick) in the video below.
