HDMI Into an AV Receiver: The Chain Is the Risk
Quick answer / TL;DR: Short answer: use 18 Gbps Premium High Speed cables on both the source-to-receiver and receiver-to-display links for 4K60 HDR, and 48 Gbps if either end is HDMI 2.1. Confirm the receiver supports HDCP 2.2 and HDR pass-through. If it does not, connect the source directly to the display and return audio over eARC.
Four versions, four bandwidth ceilings: the cable must match the signal.An AV receiver sits between sources and the display, so it must pass both video and audio. An older receiver caps the whole chain.
Two cables are involved, and both must meet the same tier.
Chain Requirements
| Element | Requirement | Failure |
|---|
| Source to AVR | 18 Gbps | 4K60 drops |
| AVR pass-through | HDCP 2.2, HDR | Black screen |
| AVR to display | 18 Gbps | Mode fallback |
| Audio return | ARC or eARC | No TV audio |
The pass-through row is the usual culprit: the receiver negotiates with the display and reports its own limits to the source.
Practical Checks
- Confirm the receiver input supports HDCP 2.2
- Enable enhanced HDMI mode if present
- Update firmware
- Test with a 4K HDR source
- Try a direct connection to isolate the AVR
The direct-connection test takes two minutes and immediately identifies whether the receiver is the limit.
Real-World Applications
A 2018 receiver passes 4K60 HDR and needs only two 18 Gbps cables. A 2014 receiver without HDCP 2.2 forces the direct-to-display arrangement, with audio returned over ARC.
Standards and Verification

Practical Notes
Label both HDMI runs by function. In a cabinet, source-to-AVR and AVR-to-display are easy to swap by mistake.

Frequently Asked Questions
Do both cables need to match?
Yes. The chain runs at the lowest tier.
Why does 4K fail through the receiver?
No HDCP 2.2 or HDR pass-through.
What is eARC for?
Returning TV audio to the receiver.
