I have a BayTrail board with two HDMI ports and running the default Tizen 3.0M1 release. The first HDMI shows up just fine but I can't get the second screen to display anything. I tried enabling the second screen through the kernel command line parameters (video=HDMI-1:e video=HDMI-2:e) and running xrandr. This is my output from xrandr -q
Screen 0: minimum 320 x 200, current 640 x 480, maximum 8192 x 8192
VGA1 connected 640x480+0+0 (normal left inverted right x axis y axis) 0mm x 0mm

DP1 disconnected (normal left inverted right x axis y axis)
Is there some other configuration I need? I tried this on both X and Wayland. Seems more like a DRM issue at this point.
