The CU34G2X is slightly more expensive than the 27-inch 16: 9 1440-pixel screen with similar feature sets, but the extra screen width and narrow curvature of the 1500R should provide a more immersive experience in first-person games and flight regulators.

The AOC CU34G2X provides a high-quality stand and rigid base for tool-less-attaching. Carton also includes DisplayPort, HDMI and USB cables. The IEC power cord provides the electrons needed for the panel to pull 47 watts when the backlight is set to 200 nits.
One thing we rarely see associated with gaming monitors is the calibration data sheet. AOC provides less than 3 color error information for delta E (dE) and also measures screen uniformity. Our tests matched the data; This very accurate screen is out of the box.
The CU34G2X features a thin bezel with a flush-mounted anti-glare coating that appears unsightly when the power is off. The photo shows an 8mm border with a wide trim strip at the bottom. There is almost no air gap in the front layer, which removes any grain from the image and greatly accelerates it. The sample has excellent uniformity with no bleeding, glare or hot spots.
The design is clearly gaming-oriented, but AOC has abandoned the RGB lighting system. The photos appear to glow red, but this is simply its reflective surface in action. The only LED lights are a small power indicator that flashes white during operation and orange in standby mode. The red trim runs behind the panel with two large slats and a vertical bar perpendicular to the top.
The stand is sturdy and has 5-inch height adjustment with 30-degree curves for both sides and 21.5-degree back tilt. The moves are firm and vigorous with no play. If you prefer an aftermarket mounting solution, unlock the mount to reveal a 100mm VESA bolt pattern. However you must provide your fasteners.
The control buttons are located where expected at the bottom right, but AOC has chosen to make it very small and comfortable. Although it is hard to tap, it is difficult to operate by feel. On the plus side, it doesn’t really show up, but we really wish it was bigger – or better yet, replaced with a joystick.
There are no side-mounted USB ports, but you’ll get four v3.2 connections for download on another input board for the upstream. You also get two each, DisplayPort 1.4 and HDMI 2.0. FreeSync will work with HDR with any video input but it normally requires DisplayPort for G-Sync playback (informally). They all support the full native resolution CU34G2X at 144Hz.
The OSD is the normal AOC bar at the bottom of the screen. It is divided into seven sections and includes everything needed for calibration and games. However you do not need color control. The CU34G2X is very accurate by default.
The luminance menu features brightness and contrast sliders with eight Eco modes and three gamma presets. HDR mode options are available only with HDR signals.
You can calibrate the CU34G2X by specifying the user’s color temperature, but in our tests, we were unable to optimize the display’s default grayscale or gamma tracking. The precise sRGB mode in the color temperature options and the only way to reduce the screen range from the original DCI-P3. The brightness slider is still available so this mode is useful for those who want to display their SDR content in the correct color space.
The game settings menu has all the necessary features to tweak your gameplay, including adaptive-sync toggles, MBRs, frame rate counters, and overclocking. For overclocking, a setting higher than any weak produced any shadows, but at frame rates above 80 fps, there was no blur to speak of anyway. Additionally, to access the MBR feature you have to turn off adaptive-sync, which has 20 levels of control. Each becomes darker, reducing the stain. There is also a slider to adjust color saturation and low blue reading modes here.
HDR support is becoming increasingly important to get the best gaming screen. We all agree that AMD FreeSync or Nvidia G-Sync is a must do regardless of the monitor’s maximum refresh rate. But more games are emerging that take advantage of the HDR and extended color of the DCI-P3 series. To fully realize the intent of the content creator, one should consider adding these features to their shopping list.
AOC produced several high-performance gaming monitors, and today we’re seeing one with HDR and FreeSync, the AOC CU34G2X. It promises an ultra-wide, curved panel, 34 ” diagonal, 3440 x 1440 resolution and high performance, thanks to the 144Hz refresh rate and 1ms response time.
AOC starts with a curved plate of radius 1500 mm. It features 300 NIT brightness, and although the AOC product page does not advertise the CU34G2X as an HDR display, it does support HDR with HDR10 and an expanded color gamut. FreeSync is the preferred friendly refresh technology, but we have confirmed in our tests that the CU34G2X will also run G-Sync (follow our instructions on turning on G-Sync on the FreeSync display), and both with Flavor HDR Work. The color depth is 8 bits, so 10-bit HDR signals are compressed, but this is a common practice on all basic 10-bit monitors except for the most common 10-bit.
It also includes the latest connectivity with DisplayPort 1.4 and HDMI 2.0 (see DisplayPort vs HDMI for comparison), and USB ports are version 3.2. For purists who like to dispense with adaptive-sync, there is a noise reduction option similar to GR-Sync’s option called MMB, and it works at speeds up to 144Hz refresh. FreeSync has a minimum range of 48 Hz. You won’t need the best graphics card or high-end card to run it, but you’ll need enough power to keep the speed over 48 frames per second (fps).
