--- Comment #3 from Jeff Zheng <jeff.zheng at intel.com> ---
OK. Sometime I saw this issue and sometime I didn't see this issue. It's
weired... WhenI saw one behavior, I tried to do following steps and saw the
same behavior:
1. Press monitor power button to turn the monitor off
2. Press DUT power button to turn the DUT off
3. Turn on the monitor
4. Turn on the DUT
