Denon AVC-X3700H and HDR question (for PS5 upgrade)

[JGreg]

Hi pros.

I'm looking to upgrade my setup for the imminent PS5. Think I've settled on the LG OLED65CX5LB and the Denon X3700H.

The only question mark still hanging is the Dolby Vision support. The tv does it but the Denon website seems to conflict with the whathifi review on that amp. Denon has a dash through Dolby Vision support but the review seems to state it can still do it just like the previous years model.

So.... will I get Dolby Vision passing through that amp or not?

Cheers!

According to the USA site the denon does support Dolby Vision, look in overview.

However the X3700h supports eARC as does the TV, there is no need to for some devices to be plugged into the Denon.

For example AppleTV 4K (for Dolby Vision content) only supports Dolby 5.1 Atmos, & PCM 7.1 both of which work over eARC.

PS5 optimal output would be PCM 7.1 for games, that works over eARC, there is no information on the PS5 and whether it will support DV.

Yeah, just use eARC.

omgad. So I can just buy the TV and leave the amp. that's very affordable..... Doesn't that mean the tv has to support certain levels of passthrough for sound though?

what about playing 4k Blurays out of the PS5. Will the LG OLED pass through all decent 4k audio formats?

If you want 7.1 sound over eARC you need a compatible eARC sound system like the Denon X3700H.

LG CX eARC supports
PCM 7.1
Dolby Digital 5.1 + Atmos
Dolby True HD 7.1 + Atmos
Dolby MAT (PCM 7.1 + Atmos)

LG do not support DTS 5.1, DTS-HD 7.1 or DTS:X over eARC.

The Playstation can decode all audio to PCM 7.1 over eARC so even if the 4k Blu-ray is DTS-HD it will be output as (no quality loss) PCM 7.1

The only thing you would miss is DTS:X (their equivalent to Atmos), that would require plugging the PS5 into the Denon X3700H directly.

Ok I'm with you now. I really appreciate your help next010!

I've ordered the tele now thinking I didn't need the Denon, but sounds like I need the Denon anyway. I didn't realise the receiver had to support 7.1 over eARC.

So my last question (hopefully) is if I had the Denon amp, which is hdmi 2.1 - why wouldn't I just plug the PS5 into that and forget about eARC? It doesn't really give me anything if the amp has HDMI 2.1 sockets right?

If the AVR supports all the audio and video formats you want to use, then yes - you would plug everything into the AVR and just have the one eARC HDMI connection to the TV.

This gets around any limitations the TV has with outputting certain audio formats you might want to make use of from sources like a BluRay player, but would allow you to output certain audio formats (such as Atmos) to the AVR from the TV's internal apps via eARC that a normal ARC connection would not.

Hi, I just found this thread as I’m considering the same TV, PS5 and AVR setup. One of the guys said I was best to double check with someone who has the PS5 to see if there were any issues with HDMI2.1 bugs that were seen on the denon with the x-box.

Are you all setup and sorted now? Any issues?

Thanks
