--- Comment #4 from Jeff Zheng <jeff.zheng at intel.com> ---
I tried with latest BIOS (V53), connected the second HDMI port (not the default
HDMI port) to Acer HS244HQ. HDMI screen shows nothing yet. But testdisplay -i
shows :
Connectors:
id      encoder status          type    size (mm)       modes
40      39      connected       eDP     280x160         1
  modes:

.......

If I connect to the default HDMI port, testdisplay -i show all HDMI port is
disconnected.
