MULTI CHANNEL AV RECEIVER
STR-ZA3100ES/STR-ZA2100ES/STR-ZA1100ES
Connecting a 4K TV
All HDMI jacks on the receiver support 4K resolution and HDCP 2.2 (High-bandwidth Digital Content Protection System
Revision 2.2).
HDCP 2.2 is newly enhanced copyright protection technology that is used to protect content such as 4K movies.
To watch HDCP 2.2 protected content such as 4K content, connect the HDMI jacks to jacks that support HDCP 2.2 on
the TV and AV device. For details on whether the TV and AV device are equipped with HDCP 2.2-compatible HDMI jack,
refer to the operating instructions of the connected device.
When you use high bandwidth video formats such as 4K/60p 4:4:4, 4:2:2, and 4K/60p 4:2:0 10 bit, etc., be sure to set
the HDMI signal format. For details, see
When an HDCP 2.2-compatible HDMI jack on the TV is labeled "eARC" or "ARC" (*)
HDMI cable (not supplied)
*
The eARC or ARC function sends digital sound from a TV to the receiver using only an HDMI cable.
Note
Sony recommends that you use an HDMI cable made by Sony or another HDMI-authorized cable. Be sure to use a High Speed
HDMI Cable with Ethernet. Premium High Speed HDMI Cable with Ethernet that supports 18 Gbps is required for 4K/60p 4:4:4,
4:2:2, and 4K/60p 4:2:0 10 bit, etc.
When you want to watch HDCP 2.2 protected content and the non-HDCP 2.2-compatible HDMI jack
on the TV is labeled "eARC" or "ARC"
If the HDMI jack on the TV is labeled "eARC" or "ARC" and is not HDCP 2.2-compatible, connect the receiver to the
HDCP 2.2-compatible HDMI jack on the TV using a Premium High Speed HDMI Cable with Ethernet that supports 18
Gbps. Then, connect an optical digital cable to the optical output jack of the TV to listen to digital sound.
