For competitive play and those simply enjoying strong fluidity, high refresh rates are attractive. Continuing the expansion of their their AGON PRO series, the AOC AG274QS is built with speed in mind. The monitor offers familiar ‘gamery’ styling shared with others from the series. This includes a black and red theme with coated metal stand base and dark matte plastics used elsewhere at the front. The top and side bezels are dual-stage, with a slim panel border flush with the rest of the screen plus a thin hard plastic outer component. The bottom bezel includes customisable ‘Light FX’ RGB LED lighting on its underside. A projector is also included which can illuminate the desk with one of two logo designs, in your preferred colour choice. The OSD (On Screen Display) is controlled by a joystick at the rear, towards the right side as viewed from the front. Or alternatively using the included wired ‘QuickSwitch’ remote.

AGON styling with some RGB LEDs

A 27″ 2560 x 1440 (WQHD or 1440p) IPS-type panel is adopted. This supports a 300Hz refresh rate, a bump up from the usual 240Hz or mild overclock from there – marketed towards Esport players but potentially gaining broader appreciation. Adaptive-Sync also features – including AMD FreeSync Premium with a 48 – 300Hz VRR range, plus LFC. Other aspects to note include a matte anti-glare screen surface, 178°/178° viewing angles, 1000:1 static contrast ratio and 8-bit colour support. A WLED backlight provides a 94% DCI-P3 (122% sRGB, 91% Adobe RGB) colour gamut, 350 cd/m² typical maximum luminance and 600 cd/m² HDR peak luminance. Low Blue Light (LBL) settings are also included to provide a more relaxing viewing experience. VESA DisplayHDR 600 support is offered, allowing the screen to put its reasonably generous gamut to good use alongside 10-bit colour processing and some decent bursts of brightness. A degree of local dimming is also included to provide a situational contrast boost, with 8 edge-lit dimming zones included.

A 1ms grey to grey response time is specified (pinch of salt required) alongside a 0.5ms MPRT response time, using the included MBR (Motion Blur Reduction) strobe backlight setting. The stand offers full adjustability, including 130mm (5.12 inches) height adjustment and pivot into portrait. It attaches centrally via a quick-release mechanism and can be removed to reveal 100 x 100mm VESA holes for alternative mounting. Either side of the attachment point are strips of customisable ‘Light FX’ RGB LEDs, shown red in the image below. The ports face downwards and include; DC power input (external ‘power brick’), 2 DP 1.4 (with DSC) ports, 2 HDMI 2.0 ports, a 3.5mm headphone jack, a 3.5mm microphone jack and 4 USB 3.2 Gen1 ports (plus upstream). 2 x 5W DTS speakers are included for sound output which is potentially a bit richer than some integrated speakers. The monitor supports up to 2560 x 1440 @120Hz for the Xbox Series X and up to 1920 x 1080 @120Hz for the PS5.

Side profile with retractable headphone hook

The monitor is listed with an RRP of ~£930. No current confirmation of a US release for this model.
