Issue 2:

Do not use both HDMI and
DisplayPort™ video connections

Troubleshooting of the issue determined that both the High Definition Multi-media Interface (HDMI) connection and the DisplayPort™ (DP) connections were connected to the same graphics adapter at the same time. Both of these display connections carry video and audio signals. Using both at the same time attached to the same graphics adapter causes audio interference (Buzzing).

Only one of these connections is required for normal operation (see the setup guide page 18). If both DP and HDMI connections are available, the DP connection is generally the preferred connection to use.
