In terms of the design, the AOC Agon AG405UXC is about as stealthy as its possible to be considering the sheer size of this screen. It's almost entirely black, with just a small AGON logo printed in red on the bottom bezel. The top and side bezels are nice and slim too, measuring about 6mm, though the chin is thicker at approximately 1.9mm.
The stand uses a v-shaped metal base and while it is quite wide at 66cm, if you're buying a 40in monitor it's safe to say you will have a large enough desk to accommodate this!
Speaking of the stand, it offers a good range of ergonomic adjustments. We get up to 150mm of height adjust, 30 degrees of swivel both left and right, as well as tilt from 3.5 degrees downards to 21.5 degrees upwards. There's no pivot functionality here, which is understandable considering the size of the screen, though third-party Vesa 100×100 mounts are supported.
General ports and connectivity options are split in two areas. The left hand side is home to power input and a power switch, while all the video inputs are found on the right hand-side. These include 2x HDMI 2.0, 1x DisplayPort 1.4 an 1x USB-C that supports DP Alt mode as well as 90W power delivery. There's also an audio jack, USB upstream port, and then 4x USB Type-A downstreams.
On the chin we also find six buttons used to control the monitor's OSD. More convenient is the included remote control which I much prefer to using fiddly buttons – a joystick would have been even better in my opinion as you can't lose it, but the remote works fine.
