AOC CU34G2X: Overview

Support for HDR is becoming increasingly crucial when it comes to selecting the finest gaming monitor. We can all agree that AMD FreeSync or Nvidia G-Sync are required regardless of the maximum refresh rate of a display. However, more games are utilizing HDR and the wider color range of the DCI-P3 standard. To fully understand the creator’s aim, it is necessary to consider adding these qualities to one’s shopping list.

AOC has created several high-performance gaming monitors, and now we’re looking at the AOC CU34G2X, which features HDR and FreeSync. It’s a 34-inch diagonal, 3440×1440 resolution curved VA panel that promises outstanding performance thanks to a 144 Hz refresh rate and a stated 1ms reaction time.

AOC begins with a curved panel having a radius of 1500mm. It boasts a stated 300 nits of brightness, and while AOC does not identify the CU34G2X as an HDR monitor on its product page, it does support HDR via HDR10 and an extended color gamut. While FreeSync is the preferred adaptive refresh technology, we confirmed in our tests that the CU34G2X supports G-Sync as well, and both varieties supported HDR. Because the color depth in AOC CU34G2X of 10-bit HDR signals is 8 bits, they are compressed, but this is standard practice for all except the most costly 10-bit native monitors.

Additionally, AOC CU34G2X supports the newest communication standards, including DisplayPort 1.4 and HDMI 2.0 (for a comparison, see our DisplayPort vs. HDMI article), and the USB ports are version 3.2. For purists who would prefer to forego Adaptive-Sync, there is a blur-reduction option called MBR that works at frame rates up to 144 Hz, akin to G-ULMB. Sync’s FreeSync’s minimum frequency is 48Hz. You won’t need the best or even a high-end graphics card to drive it, but you will need enough horsepower to maintain the action above 48 frames per second (fps).

The AOC CU34G2X is slightly more expensive than 27-inch 16:9 1440p displays with comparable feature sets, but the wider screen and tight 1500R curvature could provide a more immersive experience in first-person shooter games and flight simulators.

Accessories and Unpacking

AOC includes a high-quality stand and a sturdy base for the CU34G2X that easily mounts to the panel. Additionally, the box contains DisplayPort, HDMI, and USB cables. An IEC power cord supplies the electrons required by a panel that consumes 47 watts with the backlight set to 200 nits.

A calibration data-sheet is something we rarely see included with gaming monitors. AOC also provides information on color errors with a Delta E (dE) of less than three and a screen uniformity measurement. Our tests confirmed the data; this monitor is quite accurate straight out of the box.

Design

When the power is turned off, the CU34G2X features a narrow bezel with a flush-mounted anti-glare coating that appears frameless. The illustration depicts an 8mm border with a broader bottom trim strip. The front layer has a little air gap, which eliminates grain and produces an extremely sharp image.

The AOC CU34G2X’s styling is unmistakably gaming-oriented with RGB lighting. While the red trim appears to glow in the photographs, this is only the reflecting surface of the trim in action. The only LED illumination is a tiny power indicator that shines white when in use and orange when on standby. The red trim continues around the back, accented by two huge chevrons and a vertical stripe on the upright.

The stand is sturdy and adjustable to a 5-inch height with a 30-degree swivel to each side and a 21.5-degree back tilt. Without any play, the movements are strong and certain. If you choose to use a third-party mount, the stand unsnaps to reveal a 100mm VESA bolt pattern. You will, however, need to supply your own fasteners.

The control buttons are located beneath and to the right, as expected, however, AOC chose to make them extremely small and recessed. While they click securely, they are difficult to manipulate intuitively. On the plus side, they do not protrude visibly, but we wish they were larger – or, better yet, replaced by a joystick.

There are no side-mounted USB ports, however, the input panel features one upstream and four downstream v3.2 connections. Additionally, you receive two DisplayPort 1.4 and two HDMI 2.0 ports. While FreeSync with HDR is compatible with any video input, running G-Sync (unofficially) requires DisplayPort. All of these models support the AOC CU34G2X’s native resolution of 144 Hz.

AOC CU34G2X 34 Review: Gaming FPS

Without a doubt, AOC CU34G2X performed admirably when used to play SDR games such as Tomb Raider. Due to the increased color and contrast, elements such as granite faces and metallic textures practically leaped off the screen. You can tell AOC did an excellent job with the color engineering here because the reds never appeared oversaturated, and the critical flesh tones appeared completely realistic. The highlights were lovely and brilliant, while the shadows remained deep and detailed. We did not need to use the shadow control option to see clearly in the game’s darkest areas.

With FreeSync enabled and Tomb Raider set at the medium setting, frame rates were between 65 and 70 frames per second on an AMD Radeon R9 285-powered system. While the AOC CU34G2X is not officially G-Sync compatible, we tested it with an Nvidia GeForce GTX 1080 Ti and saw 120-130 frames per second with all settings enabled. Additionally, we experimented with several overdrive settings and determined that Weak was the best option. It added some motion resolution without introducing ghosting.

Changing Windows to HDR proved to be an intriguing experiment. Because the AOC CU34G2X isn’t particularly bright, we increased the brightness slider on the control panel and then launched Call of Duty: WWII. A few adjustments to the in-game controls resulted in acceptable highlights and deep blacks with adequate shadow detail. When the offered changes are used, this title is very well-designed to deliver an excellent visual on any display.

AOC CU34G2X 34 Review: Other High End Games

Frame rates averaged approximately 50 frames per second while using FreeSync and a Radeon R9 285 and 100 frames per second when using G-Sync and a 1080 Ti. Call of Duty: WWII requires some additional processing power, and HDR slowed things down slightly. In either scenario, the image was stunning. We spent some time examining a Paris office building that included rooms that were either well illuminated or obscured by heavy lamp shadows. The additional color assisted in bringing murky elements out of the fog while highlighting highlights. While we wished for a bit more brightness, the vista was quite entertaining after our eyes acclimated. This is the allure of a closely curved monitor such as the AOC CU34G2X. When seated approximately 3 feet away, it’s 1500mm radius wrapped the image to the boundary of our peripheral vision. With 109ppi available, pixel density was never an issue.

As with other curved monitors with superior video processing and a rapid refresh rate, the CU34G2X delivers a gaming experience that is unmatched by any 16:9 flat panel. While we’ve been quite content with flat panels 32 inches and more, the ultra-wide remains our preferred gaming device.

Conclusion

Although the AOC CU34G2X is not the brightest monitor available, its high natural contrast and extremely accurate color give an amazing image. With a refresh rate of 144 Hz and support for FreeSync and G-Sync (unofficially) with HDR, game functionality is among the best at this price point. It without a doubt deserves significant consideration for ultra-wide seekers.
