Further information on supporting our work.The 3440 x 1440 UltraWide experience can be very rewarding for gamers. And also nice to have on the desktop or when watching video content that suits the 21:9 aspect ratio. The AOC CU34G3S (CU34G3S-BK owing to mainly black stand) of the AGON G3 Series features a 34″ screen of this resolution, combined with a generous curve to help draw you into the experience. Design cues are taken from older models such as the popular CU34G2X, with an interestingly-shaped stand base and plenty of matte black plastic combined with some red plastic elements. In our experience these tend to look more subdued and less eye-catching than in marketing images of the product. The top and side bezels are dual-stage, with a slim panel border flush with the rest of the screen plus a slim hard plastic outer part. The OSD (On Screen Display) is controlled by buttons which face downwards on the underside of the bottom bezel, towards the right side.
The monitor uses a 34″ 3440 x 1440 (21:9 UltraWide) VA panel with steep 1000R curve. A 165Hz refresh rate is supported alongside Adaptive-Sync, including AMD FreeSync Premium and Nvidia’s ‘G-SYNC Compatible Mode’. A 48 – 165Hz VRR range plus LFC is offered. Other aspects of note include a light matte anti-glare screen surface, 3000:1 static contrast ratio, 178°/178° viewing angles and true 8-bit colour output. A flicker-free WLED backlight delivers 300 cd/m² typical maximum luminance and 89% DCI-P3 coverage (119% sRGB). HDR10 support is included, very basic HDR support that falls short of even the lowest VESA DisplayHDR level. Allowing 10-bit colour processing to be used with the aid of GPU dithering and allowing the reasonably generous colour gamut to be put to good use. But not requiring a particularly high luminance or local dimming on the backlight to enhance contrast.
A 4ms grey to grey response time is specified (approach with caution) alongside a 1ms MPRT response time using the MBR (Motion Blur Reduction) strobe backlight setting. The stand is attached centrally using a quick-release mechanism and can be removed to make way for an alternative 100 x 100mm VESA compatible solution. The stand offers tilt, swivel and height (130mm or 5.12 inches) adjustment. The ports face downwards and include; AC power input (internal power converter), a 3.5mm headphone jack, 2 DP 1.4 ports, 2 HDMI 2.0 ports and 4 USB 3.2 Gen1 ports (plus upstream). 2 x 5W speakers are included for potentially fairly rich and powerful sound output.
Further details can be found on the manufacturer’s product page. The monitor is listed for ~$430 USD.
