Follow up: Just hooked up a 2nd panel. Will continue to give feedback on the user experience. When I plugged it in, it made the mDP output the primary and the HDMI output secondary. I'm using a mDP to DP cable (native cable, no adapters) and a regular HDMI cable no frills from startech.
Other specs are:
Crucial MX200 250GB SSD
Crucial 8GB DDR4 memory kit CTK4G4SFS8213 (2x4GB DDR4)
