Main trade-off
Denon AVR-S980H
Its second HDMI monitor output repeats the same source. It cannot separate a game in one room from a film in another.
Head-to-head
Denon AVR-S980H vs Onkyo TX-NR6100: Onkyo offers more second-room routes, neither powers 5.1.2 plus stereo Zone 2
The short answer
Choose TX-NR6100 when a separate room needs a supported HDMI source or an external stereo amplifier. Its Zone 2 routes are more flexible, but input and audio-format restrictions matter. Choose S980H for a same-source TV/projector arrangement or an existing compatible HEOS household. Neither can power 5.1.2 in the main room and a stereo second room from its seven built-in amplifier channels.
Before you choose
The reasoning and the trade-offs
A console and a film need two source paths, not just two screens
If one person plays in the living room while another watches a player in a second room, S980H’s two outputs do not separate the programs. TX-NR6100 offers the more suitable route through its configurable HDMI Zone 2 output. That recommendation comes with a wiring plan: Onkyo identifies HDMI IN1 to IN3 for external zone sources, and its zone audio restrictions must be met. A single player cannot become two different programs either. List the actual sources and where each must appear before buying.
What this is based on
Denon documents same-image monitor outputs. Onkyo documents separate zone sources, SUB/ZONE 2 assignment and HDMI IN1 to IN3 restrictions. No unrestricted 4K120 or every-format zone promise is made.
Main trade-off
Onkyo TX-NR6100
Zone 2 is restricted to suitable inputs and formats. NET and Bluetooth playback cannot become two independent streams simply by selecting different rooms.

- Choose it for
- Both displays show the same source and you want the receiver to join existing compatible HEOS equipment.
- You need the documented 1440p100/120 route and do not need an independent HDMI Zone 2 program.
- Main trade-off
- Its second HDMI monitor output repeats the same source. It cannot separate a game in one room from a film in another.
Onkyo TX-NR6100
- Choose it for
- A second room needs its own supported HDMI source, with the required Zone 2 input and signal settings.
- An external stereo amplifier can power second-room speakers while the receiver keeps its main-room height channels.

About this comparison
S980H or TX-NR6100 for movies, gaming and a second room? Compare shared HDMI outputs, independent zone sources and the limits behind multiroom audio.
These are plausible alternatives for a seven-channel living room that also serves another screen or listening area. The distinction is how the second room connects. Onkyo has configurable HDMI Zone 2 and analog line outputs, while Denon offers same-source monitor outputs and HEOS integration.
Winner by situation
Start with what you need it to do
A game and a film from separate supported HDMI players
Onkyo offers HDMI Zone 2. Plan IN1 to IN3 and the required zone formats.

Main-room heights plus a separately amplified kitchen
Onkyo’s LINE OUT avoids using main-room height amplifiers for the kitchen.

Same-source TV/projector use within an existing HEOS setup

Two unrelated NET/Bluetooth streams on the Onkyo receiver
Onkyo shares those selections. Denon needs its own exact multiroom service check rather than an assumed win.

What matters in practice
The differences that matter
A console and a film need two source paths, not just two screens
If one person plays in the living room while another watches a player in a second room, S980H’s two outputs do not separate the programs. TX-NR6100 offers the more suitable route through its configurable HDMI Zone 2 output.

How we reached this conclusion
Denon documents same-image monitor outputs. Onkyo documents separate zone sources, SUB/ZONE 2 assignment and HDMI IN1 to IN3 restrictions. No unrestricted 4K120 or every-format zone promise is made.
An external kitchen amplifier prevents a hidden Atmos compromise
When someone cooks while others watch a film, TX-NR6100’s LINE OUT can feed a suitable kitchen amplifier without assigning the receiver’s height channels to that room. Using Onkyo’s powered Zone 2 terminals instead stops height or surround-back playback. S980H has the same seven-amplifier bottleneck when it powers another room, but lacks this external Zone 2 line-out alternative. Onkyo makes more sense if independent kitchen listening is frequent and you can accommodate the extra amplifier.
How we reached this conclusion
Both powered-zone layouts consume two channels from a seven-amplifier system. Onkyo separately documents Zone 2 LINE OUT and external volume control. The inference is about preserving channel assignment, not guaranteed source compatibility or measured sound.
Two rooms cannot always choose two different streams
Onkyo is more flexible with supported separate sources, but its NET and Bluetooth selections are shared between rooms. Someone choosing Bluetooth in the kitchen can change what a NET listener hears in the main room. That matters if the purchase is meant to stop household arguments over music. S980H is worth considering when compatible HEOS speakers already handle the other rooms and you want that established setup to remain. Check the exact streaming services and simultaneous-playback rules on either system. The brand badge alone does not answer that question.
How we reached this conclusion
Onkyo explicitly states that NET/Bluetooth selections share a source across rooms and switching one can switch the other. Denon documents HEOS compatibility. No claim of unlimited independent HEOS subscriptions, accounts or streams is inferred.

A powered subwoofer is separate from the speaker-channel count. This checks one main room. Zone 2, bi-amping and unusual speaker assignments need another manual check. Allow ventilation space and confirm HDMI settings, cables and speaker impedance before installing.

Meaningful differences
What changes the fit
| What changes | Denon AVR-S980H | Onkyo TX-NR6100 | Why it matters |
|---|---|---|---|
| Second HDMI destination | Same-source monitor output | SUB/ZONE 2 output can be configured for a second room | A second screen and a second independent activity are different requirements. |
| External second-room amplifier | No Zone 2 line-level output | ZONE 2 LINE OUT supports an external amplifier | Onkyo can avoid taking main-room amplifier channels to power another room. |
| Powered Zone 2 and heights | Five main channels plus stereo Zone 2 | Height or surround-back playback stops during powered Zone 2 output | Neither provides nine powered channels from seven amplifiers. |
| External HDMI sources to Zone 2 | No independent HDMI Zone 2 output | HDMI IN1 to IN3, with documented zone signal limits | Plan the input assignment before filling the sockets with game systems and players. |
| Second-room audio format | No equivalent Zone 2 line-out route | External source audio must be analog or two-channel PCM | A surround-bitstream source may need a changed setting before the second room hears it. |
| Existing streaming equipment | HEOS integration with compatible devices | NET/Bluetooth selections are shared across its rooms | Check the intended simultaneous sources. Multiroom labels do not promise independent streaming everywhere. |
What you give up
Every choice has a cost
If you choose Denon AVR-S980H
- Powered second-room speakers use the channels otherwise available for main-room height or rear speakers.
If you choose Onkyo TX-NR6100
- Preserving main-room heights while playing second-room speakers needs an external amplifier through LINE OUT, not the powered Zone 2 terminals.
Recommendation switch
The decision flips if...
Your compatible HEOS equipment already handles other rooms
Choose Denon AVR-S980H. S980H preserves that route when same-source monitor outputs are sufficient.
A supported separate HDMI source or external zone amplifier is essential
Choose Onkyo TX-NR6100. TX-NR6100 provides those routes, with input and audio-format restrictions.
The receiver alone must power 5.1.2 plus two kitchen speakers
Choose neither. Both have seven main amplifier channels, while this combination needs nine.
What matters in practice
Before you choose
You want one receiver to simplify two rooms, but sharing hardware can force the two people using it to share a source or give up speakers.
What this comparison cannot tell you
- No unrestricted resolution or Dolby bitstream promise is made for HDMI Zone 2.
- Streaming compatibility is service-dependent. Existing HEOS ownership is a conditional reason to choose Denon, not a claim of superior sound.
