Xg1v4 4K resolution not working when using A/V receiver

I recently upgraded my TV to a 4K-compatible TV (LG OLED65CXPUA). I also use an A/V receiver that I have confirmed is capable of 4K pass through (Sony STR DN-1040). I use HDMI cables that are certified for 4K throughput. I have the TV connected to the receiver via the ARC-capable HDMI port on the TV and the ARC-capable output port on the receiver. The X1 XG1v4 is, of course, connected to the receiver via HDMI as well.


The X1 box doesn't recognize the 4K compatibility of my setup. Oddly (as an aside), despite selecting LG as the brand during remote pairing, the X1 box thinks the TV is a Sony. If I connect the HDMI cable from the TV directly to the X1 box, the box then recognizes the 4K compatibility and I am able to set 4K resolution in the video display settings for the XG1v4 box. But then I'm stuck with the internal TV speakers. 

So the issue is clearly the X1 box not recognizing the 4K compatibility of the TV via the 4K pass through of the receiver. And, thus, the video display settings of the XG1v4 limits me to 1080p HD as the best possible setting. Is there a way to fix this issue?

connect the set top box to the TV's HDMI1 or HDMI2 (check TV's owner's manual). connect the TV to the sound bar via ARC to return your audio to the receiver (ARC is Audio return channel). working?

Hey Wheaties,

This appears to have something to do with the DN1040 not supporting HDCP 2.2. I'll let you Google around and find more detail. Sorry. My DN1080 does pass through 4k / HDR from all my sources. It's a pretty good amp, although now kind of old, and not too expensive. I guess people now like the Denons a little better in the same class. Best Christmas presents are the ones we give ourselves ...

Oof. Thanks for the tip about HDCP 2.2. I was unfamiliar with that copy protection standard. You're correct that Sony receivers before the STR-DN1060 appear to not support it. Ugh. 

Looks like I'll have to put a new receiver on my wish list.

Thanks for the quick reply. Your suggestion makes sense. The direct connection between the XG1v4 and the TV would allow for the 4K image while the ARC-equipped HDMI connection run from the TV to the receiver would push the audio to my speakers. (I'm using a 2-speaker bi-amp setup).

 

Giving it a try, it indeed seems to work now. Thank you!
