The AOC AGON AG322QC4 takes its predecessor, the AG322QCX, and kicks it up a notch by adding VESA certified DisplayHDR 400 support as well as the second generation FreeSync technology.

Other specs remain the same including the 2560×1440 QHD screen resolution and the 144Hz refresh rate.

Furthermore, the AOC AG322QC4 features a stylish design with full ergonomic support and rich connectivity.

Image Quality

The DisplayHDR 400 certification indicates that the AOC AG322QC4 display features a true 8-bit color support and a 400-nit peak brightness which makes for a slight but noticeable difference over the standard monitors.

Based on a VA panel with a 2,000:1 static contrast ratio, black colors are truly black while the whites remain bright giving you eye-catching details in return.

Moving on, the implemented AMD FreeSync 2 technology means that the display meets at least 90% of the DCI-P3 color gamut coverage.

Other panel related specs include the 178-degree viewing angles and a 4ms response time speed both of which should be taken with a grain of salt as the VA panel monitors usually shift in contrast when viewed from certain angles while the fast-paced games suffer from trailing of the fast-moving objects.

Lastly, the WQHD resolution on the 31.5-inch screen offers fairly rich pixel density. Although some folk would prefer the 4K resolution at such monitor size, this way you also get the rapid refresh rate of 144Hz and therefore a much smoother gameplay experience.


For a display to qualify for AMD FreeSync 2, it must meet certain criteria when it comes to the input lag performance. Moreover, AMD’s LFC (Low Framerate Compensation) must be supported which means that the higher end of the dynamic refresh rate range (144Hz) is at least 2.5 times greater than the lower end.

This allows the framerate to be doubled when it falls below the dynamic range ensuring smooth performance.

All AMD graphics cards that support first-generation FreeSync are fully compatible with the FreeSync 2 displays. In essence, this technology eliminates screen tearing and stuttering by synchronizing the monitor’s refresh rate to the graphics card’s GPU. You can learn more about FreeSync here.

Those with NVIDIA cards will also be able to use the monitor, but without the dynamic refresh rate technology.

The AOC AG322QC4 HDR monitor also packs its bundle of gaming-related features common to AOC. These include ‘Low Input Lag’ which bypasses certain image processing to further reduce the input lag, ‘Shadow Control’ for better visibility in dark areas of games, and finally, the Game Mode which consists of pre-calibrated gaming picture presets.

Design & Connectivity

As far as the design is concerned, the AOC AG322QC4 offers full ergonomic support including the ability to tilt, swivel, pivot, height adjustment, and VESA mount the monitor to the wall via 100 x 100 hole pattern.

Also included are the headphones hook, a light matte screen coating, and the LED strips at the back which can glow in red, green, or blue color at three different intensity levels.

The monitor features a 1800R curvature for added immersion.

The extensive connectivity includes two HDMI 2.0, two DisplayPort 1.2a, a VGA, an audio line-out for the headphones, line-in for the 2x5W integrated speakers, a microphone jack, and a dual-USB 3.0 hub.

Price & Similar Monitors

The AOC AG322QC4 price is €600 MSRP while the release date is June 2018. The previous model without HDR and FreeSync 2 is available for €100 less which you can read more about here.

We warmly welcome the latest addition of FreeSync 2 gaming monitors to the market which finally gives the AMD users choice for variable refresh rate displays without compromises which is the case with the previous generation FreeSync monitors with usually very narrow dynamic refresh rate range.
