AOC CU34P2C review: a versatile and affordable 34-inch 100 Hz widescreen monitor

AOC CU34P2C, a very classic screen in a black dress.

The AOC CU34P2C monitor is completely black. The finishes are excellent and the matte black plastic seems built to last. Its foot is very nice (27.5 x 27.5 cm).

Rotate up to 180° left and right.

AOC CU34P2C offers height adjustment over 15 cm and tilt between -5 and +23°. The foot can also be rotatable by ± 180 ° through a Pad located below the entire plinth. However, there is no portrait orientation – a rare and almost useless feature of a widescreen monitor.

The back of the monitor.

Like the front, the back is as minimal as possible. The connectors are pointed at the bottom, except for two USB ports on the edge. At the foot of the foot, there is a basic cable management system that allows them to be grouped in the same place.

The connection.

The connection consists of an HDMI 2.0 input, a DisplayPort 1.2, a USB-C port that delivers 65 W, two USB 3.0 ports and a headphone output. There are also two USB 3.0 ports on the edge, very practical for connecting a storage device such as a USB key or hard drive. It also has two 3 W speakers whose quality is not exceptional, but sufficient for watching short videos.

Remember that the USB-C port allows you to charge the laptop, to use the two USB 2.0 ports located on the back to connect a keyboard and a mouse, for example, as well as two USB 3.0 ports located on the edge and sent. the video signal on the screen. In short, one cable is enough and it allows you to transform the monitor into a kind of docking station. Thus the screen can mirror the computer’s clone or extend its display. The 65 W of the USB-C port charges almost all laptops on the market. Only the most powerful computers, such as 14-, 15- and 16-inch MacBook Pros, whose original power supply delivers more than 85 watts, can be prevented. In fact, it works perfectly and the integrated battery takes over during heavy loads.

The buttons to access the settings.

The buttons to access the settings.

To change settings, AOC opted for five buttons, a less practical system than the clickable joystick that many competitors have… The dated menus don’t help matters and the interface is worth 90. In short, it should not be pleasant to change the settings of this monitor.

The AOC CU34P2C was quite comfortable on our 120 x 80 cm table. The 27.5cm leg depth isn’t too much of a problem on an 80cm deep table, but it would still take up a lot of space on a shallower table. The Ultra Wide Quad HD definition of 3440 x 1440 px is still nice to use, even for office tasks with a comfortable workspace or in games where this definition remains at a good average for modern graphics cards. The resolution remains average with 110 pixels per inch, but it is enough to take a step back to 60 cm. It is still necessary to provide a powerful card to properly use this frequency definition of 100 Hz.

Colors and contrast



Out of the box and without changing the settings, the AOC CU34P2C shows a quality picture. The color temperature curve is stable throughout the spectrum and the average measured at 6820 K is close to the reference 6500 K (video standard). The gamma curve also shows good stability, with an average similar to the target value (2.2). Finally, the colors can be considered honest, because the average delta E is measured at 2 – a value below 3, the threshold below which the human eye can no longer see colorimetric drifts. Only the blue drift (5.9) remains visible. If the brightness is reduced to 23 – to get a white of 150 cd / m² – the measurements taken remain very close. The gamma remains at 2.2 while the color temperature is more equal (6800 K). After calibration, the rendering is impeccable with an average Delta E of 1.1 and no shade exceeding 3. The average color temperature goes to 6530K and the gamma is still perfect. You can download the color profile in ICC format by clicking this link.

3640:1

This monitor shows excellent contrast. Black down to 0.04 cd/m² translates into a ratio of over 3600:1. The AOC CU34P2C does not perform as well as the best VA monitors, such as the MSI Optix MAG271CR, the Philips BDM4037UW or the Huawei MateView GT 34, whose contrast exceeds 4000:1, but it shows a better contrast than AOC CU34P2C. monitors with IPS panels. This results in deep enough blacks, even in the dark.

The average difference in light homogeneity is measured at 10% across the entire 34-inch panel. Note that the model we tested was not affected by any event of dawned cloudy.

Reactivity

This screen does not use pulse width modulation (PWM or “Pulse Width Modulation“) to manage the LEDs in the backlighting system, which makes it possible to reduce the brightness without risking a flickering effect then causing eye fatigue and headaches for people who are sensitive to it. This feature is often called free flicker. It also includes a blue light reduction mode via a software setting.

This monitor is compatible with FreeSync Premium between 48 and 100 Hz and therefore works best when graphics cards send between 48 and 100 frames per second. We would still recommend a high-performance graphics card (like the GeForce RTX 3070 Ti or the Radeon RX 6700 XT) to take advantage of the native Ultra Wide Quad HD definition and very high frame rates. In all cases, fluidity is present and the image does not suffer from tearing problems (rent) or fools (microstuttering).

9.5ms

We measured the afterglow time at 9.5 ms using theoverdrive (“Superintensive” in OSD) is set to “Medium”. By pushing theoverdrive at the highest level (Strength), an effect of reverse ghosting see The AOC CU34P2C is a little less responsive than the Iiyama GB3461WQSU-B1, with an illumination time of 8 ms, but it is not a monitor dedicated to gaming and this value remains correct for an occasional gamer. . Only Samsung models like the Odyssey G7 27 or the 49G9 are better and offer an illumination time limited to 4.5 ms, but they are aimed at competitive gamers and e-sports enthusiasts. Display delay was measured at 11.3 ms at 60 Hz, a very low value that translates into almost zero lag between the action performed with the mouse or keyboard and its impact on the screen.
