AOC CU34G2X: Ports
Compared to most other current gaming monitors, the 34-inch display offers two DisplayPort inputs instead of just one. There are also two HDMI ports and a headphone jack on board. Four USB 3.0 outputs supplement the range of interfaces, but you won’t find any speakers, so you will need to provide your own.

AOC CU34G2X: Features and menu
The tabular and clearly structured screen menu offers various special game settings. There are six predefined game modes, including FPS, RTS, and racing games. There are also two game presets that the player can define on their own for further customization. One shortcoming is that the setting buttons on the bottom-right of the case are too small to allow quick and easy configuration.
The AOC CU34G2X can be adjusted in height by just over 5 inches, rotated, and tilted, and it can thus be adapted very well to any desktop situation, guaranteeing fatigue-free gaming even over a long period when set up correctly.

The curved monitor also offers special gaming settings.

AOC CU34G2X: Power consumption
The power consumption of the gaming monitor is quite high at around 65 watts at maximum brightness. Accordingly, the curved monitor only gets a lowly “C” on the energy label. In standby mode, consumption drops to a low 0.5 watts.
Final thoughts
The AOC CU34G2X monitor will no doubt impress gamers with its list of gaming presets and how well the top games perform on it. The refresh rate is more than adequate for most fast-paced games, which means you can shoot or race your way to victory without worrying about screen tearing or input lag. To take advantage of this monitor’s full range of features, you’ll need a decent gaming setup with top-quality hardware, though.
While the video processing and image quality are not exactly outstanding, they are still very solid. The CU34G2X teeters on the edge of premium quality, both in regards to its performance and its price, but relatively speaking it will run you about the same or slightly cheaper than other 34-inch ultrawide displays. You could upgrade to get better HDR performance and better image quality, but you would pay significantly more for both. So for the money, there aren’t many other ultrawide options that offer better value.
