Rotation uses the 3D engine so the largest desktop size that can be rotated with hardware is limited to the max texture size: 2048x2048 for your card. For desktops larger than that, software is used for rotation. 1280 + 1920 > 2048. Due current architectural limitations, the max size is per-desktop rather than per monitor.
