I experience the following with this configuration: SP3, Win 8.1, docking station: mdp (on docking station) to hdmi, the view-able screen on my SP3 gets noticeably smaller when the mdp to hdmi is connected to my TV which is set to input from SP3; the SP3 is set to duplicate the image onto the TV, though the TV screen is full all around the TV (LG 49 UB8500). Image on TV is excellent. Image on SP3 is also excellent, but smaller, as noted above. Has anyone experienced any reduction in SP3 screen size in your SP3 docking station using mdp to hdmi connection? Anyone have any recommendations if this is inconsistent with the way things are supposed to be with this setup.
