--- Comment #25 from Mahesh Kumar <mahesh1.kumar at intel.com> ---
Hi,

Can you please help here to understand the issue little better.

Is only second monitor going blank or both the monitors are going blank?
I could see multiple hot-plug events and under-runs around those events, Is hot
plug/un-plug is involved in test scenario or this is monitor/cable problem
which is triggering hotplug?

Is it particular 4K monitor in which issue is reproducible or all 4K monitor
are causing this issue. Can you please try with some other 4K monitor to see if
issue is still reproducible.
