AV Receivers Compared for Low Lag Gaming Audio
Denon AVR-X3800H carries 4K 120Hz on all six HDMI inputs, so a PS5, a Series X and a gaming PC connect at once. Marantz Cinema 50 uses the same platform with cinema voicing. On a tight budget, Onkyo TX-NR6100 keeps VRR and ALLM across three inputs.
Denon AVR-X3800H is the pick for a multi console living room, since every one of its six HDMI inputs carries 4K 120Hz with VRR and ALLM. Marantz Cinema 50 shares that platform and switches into game mode faster. Onkyo TX-NR6100 covers a single console for far less.
Shopping here is awkward because port count and gaming bandwidth are different numbers. Several models advertise 8K while routing full bandwidth to one or two sockets, and early HDMI 2.1 units dropped 4K 120Hz from certain consoles until a firmware fix landed. We checked manuals for which specific inputs carry 4K 120Hz, confirmed VRR and ALLM in the published feature lists, then weighed channel count, room correction and firmware history.
The top picks, ranked
Denon AVR-X3800H
Six inputs carry 8K 60Hz and 4K 120Hz, which removes the switch box from a three console setup. VRR, ALLM, QMS and QFT all pass through, and Audyssey MultEQ XT32 calibrates from a supplied measurement microphone. Nine amplified channels cover a 7.1.2 or 5.1.4 Atmos layout alongside the gaming duties.
Pros
- All six HDMI inputs pass full 4K 120Hz
- MultEQ XT32 is the strongest correction system here
- Drives a 7.1.2 Atmos layout without extra amplifiers
Cons
- Setup menus are dense for a first receiver
- Chassis depth demands a deep rack shelf
Marantz Cinema 50
Cinema 50 runs the same HDMI 2.1 platform as the Denon picks, with six inputs at 8K and 4K 120Hz plus VRR and ALLM. Owners report the handoff into low latency mode settles quicker when a console wakes from rest. Marantz voicing and a shielded front panel suit a system that plays films as seriously as games.
Pros
- Six full bandwidth inputs, matching the Denon
- Quick automatic switch into game mode
- Smoother presentation on film soundtracks
Cons
- Sits well above the Denon on outlay
- Heavy chassis needs ventilation clearance
Onkyo TX-NR6100
Three of its HDMI inputs carry 4K 120Hz with VRR and ALLM, which is everything a single console needs. Seven channels cover a 5.1.2 Atmos room rather than a large layout. THX certification on the amplifier section is rare at this level, and AccuEQ handles basic room correction.
Pros
- Lowest outlay route to 4K 120Hz and VRR
- THX certified amplifier section
- Compact enough for a narrow TV stand
Cons
- Three gaming inputs cap future sources
- AccuEQ trails Audyssey on room tuning
Yamaha RX-A4A Aventage
YPAO measures from several seating positions, which helps in rooms with a bay window or an open kitchen behind the sofa. Three HDMI inputs pass 4K 120Hz with VRR and ALLM. Aventage construction adds a fifth centre foot and heavier internal damping, and stereo music stays clean rather than merely loud.
Pros
- Multi point YPAO copes with awkward room shapes
- Aventage chassis damping reduces cabinet vibration
- Music playback beyond most gaming receivers
Cons
- Only three inputs carry 4K 120Hz
- Control app is less intuitive than rivals
Sony STR-AN1000
Sony links this receiver to a connected PS5, switching picture and sound settings by content through Auto HDR Tone Mapping and Auto Genre Picture Mode. Two HDMI inputs carry 4K 120Hz with VRR and ALLM. 360 Spatial Sound Mapping places height cues without ceiling speakers, useful where mounting is not allowed.
Pros
- Recognises a PS5 and sets modes automatically
- Height effects without ceiling speakers
- Straightforward remote and front panel
Cons
- Two 4K 120Hz inputs is the fewest here
- D.C.A.C. IX is less detailed than MultEQ XT32
Onkyo TX-NR7100
Nine amplified channels drive a 7.1.2 layout, which is the reason to step up from the 6100. Three HDMI inputs carry 4K 120Hz with VRR and ALLM. Dirac Live can be licensed on top of AccuEQ for measurement based correction, and THX certification covers the amplifier section.
Pros
- Drives a full 7.1.2 Atmos speaker layout
- Dirac Live upgrade path from AccuEQ
- THX certified with headroom for larger rooms
Cons
- Dirac Live licence is a separate purchase
- Deep chassis and high power draw
Denon AVR-X1800H
Three HDMI inputs pass 8K and 4K 120Hz with VRR, ALLM and QFT, so a console runs at full refresh in a bedroom system. Seven channels cap the layout at 5.1.2. Audyssey MultEQ is included and the paid app allows custom target curves, though no pre outs means external amplification is off the table later.
Pros
- 8K and 4K 120Hz across three inputs
- Audyssey app allows custom target curves
- Fits shallow stands and apartment setups
Cons
- Amplifier power suits smaller rooms only
- No pre outs for external power amps

How to pick the right one
What to look for in a gaming AV receiver Start with the number of inputs that actually carry 4K 120Hz, not the total socket count. Confirm VRR and ALLM appear in the gaming feature list, because 8K on its own means little today. Channel count follows from your speaker plan rather than from the games. Room correction quality separates otherwise similar models, and Audyssey MultEQ XT32 sits at the top of that ladder here. Check the manual last, since marketing copy blurs which port does what.
Which HDMI 2.1 features actually matter for consoles Variable Refresh Rate syncs the display to the console frame rate, removing tearing when a game dips below its target. Auto Low Latency Mode flips the whole chain into game mode without touching a remote. Quick Frame Transport shaves latency further by sending each frame faster inside the same refresh window. 8K passthrough is the least useful of the group, since neither current console outputs 8K gameplay. Read the gaming line on the specification sheet, because a receiver can list 8K and omit VRR entirely.
How to match channel count to your room Channel count changes your speaker layout, never your gaming features. Seven channels cover 5.1.2, which fits a bedroom or apartment where ceiling speakers sit ahead of the seating. Nine channels open 7.1.2 or 5.1.4, worth having in a room over roughly 300 square feet with space behind the sofa. Pre outs decide whether external amplification is possible later, and budget models frequently leave them off. Size the amplifier to the room before comparing gaming specifications.
What the 4K 120Hz firmware issue was and how to check for it Early HDMI 2.1 receivers carried a chipset fault that blanked the screen when a PS5, an Xbox Series X or an RTX card sent 4K 120Hz. Manufacturers issued firmware updates, and some units needed an external adapter instead. Current stock ships corrected, though confirming costs nothing. Update firmware before mounting anything, then test each console at its highest refresh rate. Owners report the failure appears as a black screen rather than a lower resolution picture, which makes the cable an easy thing to blame wrongly.
Questions worth asking
Do you need HDMI 2.1 for PS5 and Xbox Series X?
For 4K at 120Hz you do, since HDMI 2.0 cannot carry that bandwidth. Gaming at 4K 60Hz or 1080p works fine on an older receiver. Every model here leaves room to move up later.
What is VRR and does it matter for console gaming?
Variable Refresh Rate lets the display follow the console frame rate instead of a fixed clock. Tearing and stutter disappear when frame rates fluctuate mid scene. All seven receivers here pass VRR through to a compatible television.
Does an AV receiver add input lag?
A modern receiver in game mode adds only a small delay, and ALLM engages that mode automatically. Owners report the difference is not noticeable in normal play. Competitive players sometimes run the console straight to the television and return audio over eARC.
How many HDMI 2.1 ports do you actually need?
Count your high refresh sources, since each one occupies a full bandwidth input. A single console needs one, while a PS5, an Xbox and a gaming PC need three. Denon AVR-X3800H and Marantz Cinema 50 leave the most room to expand.
What was the 4K 120Hz bug on HDMI 2.1 receivers?
A chipset fault on early units blanked the picture when a source output 4K 120Hz. Firmware updates and, in some cases, an adapter resolved it. Update on day one and test every console before committing to a wall mounted install.
Can these receivers pass 8K as well as 4K 120Hz?
The Denon and Marantz models pass 8K 60Hz alongside 4K 120Hz. Cheaper picks here focus on 4K 120Hz only. With no 8K console content shipping, that limitation costs nothing today.
Which HDMI cable is needed for 4K 120Hz?
Use an Ultra High Speed cable certified for 48Gbps. Older high speed cables cause dropouts, sparkles or a blank screen even when both devices are capable. Cable length matters too, since passive runs beyond about 3 metres get less reliable.
Is a 7.2 or 9.2 channel receiver better for gaming?
Gaming features are identical across both, so the choice is about speakers. A 7.2 model handles 5.1.2 in a normal room for less. A 9.2 model is needed for 7.1.2 or 5.1.4 in a larger space.
Can you connect the console to the TV and take audio back?
Yes, through eARC on the television, which returns lossless Atmos to the receiver. That route bypasses the receiver’s video processing entirely, so a single HDMI 2.1 input on the receiver becomes enough. Check the television has eARC rather than plain ARC before planning around it.
Which AV receiver is best for a PS5?
Sony STR-AN1000 pairs most tightly, recognising the console and switching picture and sound modes by content. Denon AVR-X3800H is the better answer where an Xbox or a PC shares the system. Both pass 4K 120Hz, VRR and ALLM without compromise.
The verdict
Denon AVR-X3800H is the receiver to buy for a household with more than one high refresh source, because six full bandwidth inputs mean nothing gets unplugged. Marantz Cinema 50 earns its step up when films matter as much as frame rates. For one console and a compact Atmos layout, Onkyo TX-NR6100 covers the same gaming features for far less.
