At the NVIDIA booth, I caught up with their mobile chip, Tegra 2, on two high profile phones. The Motorola Atrix 4G
and LG Optimus 2X
were there to show off the video output feature via HDMI as well as letting you some hands on time with gaming. Check out the video of the LG's Optimus 2X doing a mirror of the phone's display while playing a game and the Atrix 4G outputting 1080P video with the phone acting as a secondary display, being a control pad for the video.
