The boxes that feed the AVR. What each one actually outputs — max resolution and frame rate, the HDR formats, and (the part that bites people) which Dolby and DTS streams it will bitstream or pass through to your processor. Verified against each maker's spec page, June 2026.

Consoles

Device	Video	HDR	Gaming	Lossless / object audio
Sony PlayStation 5 / PS5 Pro	4K/120, 8K (HDMI 2.1)	HDR10 only	VRR + ALLM	LPCM 7.1; bitstream Dolby Digital + Atmos (games & apps). From a UHD disc: TrueHD/Atmos, DTS-HD MA/DTS:X No Dolby Vision — HDR10 only, even for movies. Disc audio needs the disc model; the Digital edition has no drive.
Microsoft Xbox Series X	4K/120, 8K signal	Dolby Vision, HDR10, HLG	VRR + ALLM + Dolby Vision gaming	Dolby Atmos + DTS:X bitstream, DD/DD+; from a UHD disc: TrueHD & DTS-HD passthrough The only console that does Dolby Vision for games. Series S is the same A/V but has no disc drive.
Nintendo Switch 2	4K/60 docked; 1080p/1440p up to 120 fps	HDR10	VRR	Linear PCM 5.1 — no Dolby or DTS bitstream Surround is uncompressed PCM only; your AVR shows "Multich PCM," never "Dolby Atmos."

Media streamers

Device	Video	HDR	Gaming	Lossless / object audio
Apple TV 4K (3rd gen)	4K/60, Match Frame Rate (24/25/30/50/60)	Dolby Vision, HDR10, HDR10+, HLG	ALLM (Match Range/Rate)	Dolby Atmos (in Dolby Digital Plus), DD/DD+, lossless PCM No DTS of any kind and no TrueHD passthrough — its "Atmos" is always the lossy DD+ version.
Nvidia Shield TV Pro	4K/60	Dolby Vision, HDR10	—	Full passthrough: Atmos, Dolby TrueHD, DTS:X, DTS-HD MA, DD+ The reference passthrough box — passes the lossless TrueHD/DTS-HD that Apple TV and Roku cannot.
Google TV Streamer (4K)	4K/60 (HDMI 2.1)	Dolby Vision, HDR10, HDR10+, HLG	—	Dolby Atmos (in DD+), DD/DD+; DTS/TrueHD passthrough is app-dependent Atmos rides Dolby Digital Plus; no guaranteed lossless or DTS passthrough.
Roku Ultra (2024)	4K/60	Dolby Vision, HDR10, HDR10+, HLG	—	Dolby Atmos (in DD+), DTS Digital Surround passthrough Passes the lossy DTS core but not lossless TrueHD or DTS-HD Master Audio.

UHD Blu-rays

Device	Video	HDR	Gaming	Lossless / object audio
Panasonic DP-UB820	4K/60 disc	Dolby Vision, HDR10, HDR10+, HLG	—	Bitstream Dolby TrueHD/Atmos & DTS-HD MA/DTS:X; 7.1 analog out; DSD Plays every HDR and lossless format there is — the all-rounder reference disc player.
Sony UBP-X700	4K/60 disc	Dolby Vision, HDR10 (no HDR10+)	—	Bitstream Atmos/DTS:X; decodes TrueHD & DTS-HD MA to 7.1 Budget Dolby Vision disc player; no HDR10+ and no analog outputs.

What trips people up

▸Neither the PS5/PS5 Pro nor the Xbox plays a UHD disc in Dolby Vision — both are HDR10-only for movies, even though most 4K discs are mastered in Dolby Vision. Only the Xbox does Dolby Vision for games.
▸Apple TV and Roku can’t pass lossless TrueHD or DTS-HD Master Audio — their “Atmos” is the lossy Dolby Digital Plus version. For lossless object audio from a ripped disc you need a Shield Pro or a real UHD player.
▸Nintendo’s Switch 2 outputs surround as uncompressed PCM only; there is no Dolby/DTS bitstream, so an AVR reports “Multich PCM,” not “Dolby Atmos.”
▸Bitstream vs PCM: a source set to “PCM” decodes Atmos internally and sends multichannel PCM (which strips the Atmos metadata over plain ARC). Set the source to “bitstream” and use eARC to keep object audio intact to the processor.
