An AV receiver is another device in the signal chain and must support the selected video mode. Its HDMI inputs, output settings and firmware can affect resolution, HDR and refresh compatibility. A successful direct connection helps locate the limitation but does not identify the exact receiver fault by itself.
Map the complete route
Write down which player output, receiver input and television input are connected. A receiver may have different capabilities across sockets or require a specific signal setting. Check the exact model’s documentation, including any restrictions that apply when multiple displays or zones are connected.
Use a controlled bypass test
Keep the same source, app and programme while connecting the player directly to the television. If practical, use the same suitable cable for one segment at a time. If the desired mode works directly, return to the receiver and compare its documented supported modes rather than changing subscription credentials.
Preserve sound requirements
A direct video route may alter how audio reaches the sound system. Before adopting it permanently, check the television’s ARC or eARC support and the formats each device accepts. Do not assume a picture fix automatically preserves surround sound. Document a stable combination of video and audio settings for everyday household use.
