Executive Summary This paper characterizes the latest Intel® Atom™ processor E6xx series B1 stepping system-on-chip platform. In this paper, necessary details on hardware capability are presented along with information on display resolution characterizations (or limitations) for maximum display resolutions allowed on each of the display outputs ...using the Intel® Embedded Media and Graphics Driver (Intel® EMGD). In summary, the only limitation that occurred was when SDVO was set as Primary screen at the SDVO's highest resolutions using dual display combination. This is a hardware limitation of the silicon and not an errata.
