AOC CU34G2X Curved Gaming Monitor Review: Speed, Immersion and HDR

The speed you need, but HDR’s lacking.

Applying an HDR signal to the CU34G2X automatically switches it to HDR mode, where you’ll find four picture options. DisplayHDR, the default, is by far the best, and it’s the only one that doesn’t apply edge enhancement to contrasting objects.

We had hoped to see more light output from the CU34G2X in HDR mode, but it topped out at about the same level as with SDR. The result was the same whether we measured full field or window patterns. Some sort of dynamic contrast or selective overdrive of the backlight would be a great improvement here. Many of today’s HDR screens can exceed 400 nits as the other monitors here do, and we prefer to hit at least 600 nits with HDR gaming. 

Fortunately, that is somewhat made up for by an excellent black level. The HDR contrast level is about the same as SDR, which isn’t ideal, but the CU34G2X still looks better than the FI27Q or EW3280U HDR monitors. Dynamic range is king, and no edge-lit monitor does it better than the Dell S3220DGF with over 18,000:1 contrast, achieved by some clever engineering of its firmware.

    I thought for sure I had already read a review on Tom's for this monitor, not long ago. Hmmmmmmmmm. I've also been looking at this monitor very hard lately. But there are others I'm looking at as well. This seems to be a well like monitor, from what I have read around the web.

    Some of the quotes make me laugh. Such as

    "While the best VR headsets still provide a greater sense of sensory deprivation, a curved 21:9 screen manages to capture much of that feeling without a bulky apparatus on your head"

    I have a widescreen monitor and a VR headset. While I love widescreen monitors they don't even come close to the impressiveness of VR. Not even a little bit.

    It seems all the stock for this monitor went to reviewers. I bought this monitor in February and I think I won't get it before next year.
