The catch
Sony STR-AZ1000ES
A third fast source may need another route, since there are two high-refresh inputs. There is no full bank of main-channel pre-outs.
Side by side
Direct TV-and-projector connections or compatible optional wireless rears point to Sony, which has two HDMI outputs while Denon has one. Three high-refresh sources or a documented front-channel external amplifier connection point to the US X1800H. Sony has two fast inputs and no full main-channel pre-outs. Both remain seven-main-channel receivers, so neither front amplification nor wireless rears create a four-height 5.1.4 system.
Before you buy
In some rooms the TV gets used most days and a projector comes out for the occasional film, and nobody wants to swap cables behind the receiver. With two outputs, Sony lets both display cables stay plugged in. Denon has one output, so that arrangement needs another verified routing solution. If you already have a switch that supports the required formats, Sony’s output advantage may count for less. Two outputs also don’t promise unrestricted simultaneous display modes, so check the display combination you’ll use.
Where this comes from
Two displays that stay connected, matched against one HDMI output versus two. The conditions on shared formats and simultaneous output still apply.

The catch
With one HDMI output, a TV and a projector can’t both stay connected directly.

Sony AZ1000ES vs US Denon X1800H for a TV-and-projector room, three gaming sources or an existing stereo amp, plus the connections that matter behind 5.1.2.
Either seven-channel receiver works for a 5.1.2 room. A single buyer could reasonably weigh Sony’s display and rear options against Denon’s additional fast input or front-amplifier route.
Which one fits
Two HDMI outputs are on Sony.
Three of Denon’s inputs are capable.
That connection is documented in the US Denon manual.
Each tops out at seven main channels.

Two consoles can take up both high-refresh inputs on Sony. A compatible gaming PC added after that needs a route through the TV input, a suitable switch or another cable change. Denon has three high-refresh inputs and can keep all three connected directly. Both have six total inputs, so the socket count alone hides the difference that matters. A spare suitable TV input and working eARC could solve the Sony routing problem, but check the whole source-to-display path.
Three fast sources, each connected on its own, set against two capable inputs and three. No blanket format compatibility is assumed for every source.
A front-channel external amplifier connection is documented for the US X1800H, so a suitable stereo amp you already have can keep working for the front speakers. Sony has no such main-channel pre-out route. Denon still processes just seven main channels, so putting the fronts on another amp won’t turn 5.1.2 into 5.1.4. What you get is reuse of your equipment and its established wiring. It adds no extra channels or better sound.
The exact US front-amplifier connection, matched against equipment already owned and a seven-channel processing ceiling that does not change.

Handles your setup
Runs 5.1.2 on its own built-in amplifiers. Takes 3 HDMI devices, 1 of them at 4K/120Hz.

A powered subwoofer does not count toward the speaker channels. This checks one main room. Check Zone 2, bi-amping and unusual speaker assignments yourself. Leave room for ventilation, and confirm HDMI settings, cables and speaker impedance before you install.

Your TV and projector need to stay connected with no external display switch.

Denon, AVR-X1800H
Three direct high-refresh inputs are needed for two consoles and a compatible gaming PC.
Spec by spec
| Spec | Sony STR-AZ1000ES | Denon AVR-X1800H | In practice |
|---|---|---|---|
| Direct displays | Two HDMI outputs | One HDMI output | On Sony, the TV and projector each keep their own cable. |
| High-refresh sources | Two inputs | Three inputs | Denon connects one more compatible fast source directly. |
| Front stereo amplifier | No full-range main pre-out route | Documented front-channel external amp connection | Denon can put suitable existing front amplification to use again. |
| Main speaker ceiling | Seven channels, 5.1.2 or 7.1 | Seven channels, 5.1.2 or 7.1 | More output hardware doesn’t make four physical heights possible alongside five ear-level speakers. |
Trade-offs
Change of plan
Go with Sony STR-AZ1000ES. Sony comes with two outputs.
Go with Denon AVR-X1800H. The input or amplifier connection that applies comes from Denon.
Decision guide
Keeping two screens connected is the goal, but three high-refresh sources or an existing stereo amp may call for a different connection plan.
