What steps will reproduce the problem?
1. Chromebox CN60 with Display Port & HDMI out + 2 Monitors
2. DP out to left monitor, HDMI to right (tested using HDMI > DVI)
3. Before enabling display spanning set the left monitor as Primary and move it to the left in the display properties.
4. Enable Spanning


What is the expected result?

Spanning would enable and honour the monitor setup. I have my DP monitor on the left and HDMI on the right and without spanning it is setup like this.


What happens instead of that?

Switches the monitors, makes the right (HDMI) monitor primary and then spans by wrapping around to the left monitor. No way to change this.
