HDMI Hot plug sporadically cause ERROR. Only connecting with ASUS(PB238)
monitor can get a high reproduction rate. I enumerate some situations like
below:
1 Connecting with other monitor, plug in and unplug HDMI ten times, I can't get
this ERROR
2 Connecting with ASUS(PB238) monitor,plug in and unplug HDMI ten times, I get
at least 5 times.
3 Connecting with ASUS(PB238) monitor,plug in and unplug HDMI until get ERROR.
Then connect with other monitor, plug in and unplug HDMI ten times, I get at
least 4 times.
