The verdict
Trusted Reviews calls it a polished, good-value receiver that suits most living-room and media-room systems. It is the step to take over the X1800H if you want a second HDMI output or a bit more power. Owners of large rooms should consider the nine-channel X3900H.
The AVR-X2900H succeeds the AVR-X2800H in Denon's X-Series. It has seven amplified channels rated at 95 W, Dolby Atmos and DTS:X, six HDMI inputs and two HDMI outputs, and Audyssey MultEQ XT with an optional Dirac Live upgrade. Reviewers like its clean, well-organised sound and connectivity. The main caveats are that only three inputs carry 8K and 4K/120 Hz, and that very large rooms may want more power.
Strengths
- Two HDMI outputs, with eARC on the main one, so a TV and a projector can both be connected.
- Three HDMI inputs take 4K/120 Hz and 8K, with VRR and ALLM listed for gaming.
- Reviewers describe a precise, spacious soundstage with strong multichannel steering.
- Audyssey MultEQ XT is included and a Dirac Live upgrade is available.
- HEOS multiroom, AirPlay 2, Roon Ready and Spotify, TIDAL and Qobuz Connect.
Weak spots
- Only three of six HDMI inputs support 8K and 4K high-frame-rate sources.
- Reviewers suggest larger rooms may want more power or a nine-channel model.
- No front HDMI input.
- Dirac Live is an optional paid upgrade, not included.
Great for
- Medium and larger living rooms and media rooms
- Systems with both a TV and a projector
- Buyers who may add Dirac Live room correction later
Skip if
- Very large theaters that need nine amplified channels
- Setups with more than three 4K/120 Hz sources

Praises its poised, immersive sound, good connectivity and value, and finds it can drive a wide range of speakers. Notes that only three HDMI inputs support native 8K and that larger rooms may want more power.
Read the originalReview of the predecessor, the X2800H, which shares the 7-channel, 95 W layout and two HDMI outputs. Found an open, authoritative sound and strong connectivity, with a dated look and slightly light bass as minor negatives.

Questions
How does the AVR-X2900H differ from the X2800H?
It is the newer model in the same position in Denon's range, with the same seven channels and two HDMI outputs. Denon still lists the X2800H too, and the maker page does not publish a point-by-point comparison.
How many inputs support 4K at 120 Hz?
Three of the six, according to Trusted Reviews. Denon lists the same three as 8K inputs.
Does it support eARC?
Yes. Denon lists eARC, and Trusted Reviews says the TV output is the eARC one.
Is Dirac Live included?
No. Audyssey MultEQ XT is included, and Dirac Live is an optional paid upgrade that the receiver is ready for.
