I connect this amp to my PC using an optical cable (SPDIF). I have now purchased a 4K monitor (LG 27MU67) which has all the connectivity to suit my requirements. This monitor supports HDMI2 and HDCP2.2
As you can image the unit is full of connectivity options. My main requirement was support for 4K video, including HDMI2 and HDCP2.2 which this unit provides. This unit also has Bluetooth, WiFi (5G) and LAN so it can be accessed from other rooms via mobiles and tablets etc.
