Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Uncalibrated – Maximum Backlight Level

To compare the G27QC’s performance, we have a collection of 27-inch QHD screens. There's the Cooler Master GM27-CF, ViewSonic Elite XG270QC, Asus ROG Strix XG279Q and Aorus FI27Q. We also included the Gigabyte G32QC, which packs the same specs into a 32-inch QHD panel.

The G27QC offers average brightness with a maximum of just over 318 nits. For gaming, video and apps; this is plenty of light in an indoor environment. Where this monitor excels is in its black levels which are the lowest of the bunch with the backlight turned up all the way. As you can see, Gigabyte manages some impressive contrast numbers for both its screens; over 4000:1 for the G27QC. Only its stablemate, the G32QC boasts more dynamic range. This bodes well for SDR and HDR content alike. 

After Calibration to 200 nits

When the playing field is leveled at 200 nits, the G32QC squeaks ahead in the calibrated black level test. But the G27QC is still comfortably darker than the other panels. This is why VA is our tech of choice for gaming monitors. Contrast is king. Even with adjustment, contrast is still nearly 4000:1 in SDR mode. It doesn’t get much better without a FALD backlight.

An ANSI contrast ratio over 3000:1 is a rare achievement for any monitor. Both Gigabyte screens can manage it. Image depth is superb and with so much contrast available, this QHD screen could pass for a 4K resolution monitor. A wide dynamic range goes a long way towards improving perceived resolution. The G27QC looks stunning.

    This is right up my alley. Ive been looking for a larger monitor to game on. And it's actually a good value. Wish it was flat though as the curve is just a marketing gimmick if you ask me. Do they have a flat version?

    Yes there's a flat one of the same model aptly named G27Q without the C at the end. (C=curve)

    I will never understand how tech sites can recommend any VA monitors for gaming with their huge issues like black smearing and certain flickering textures.

    VA for gaming ...

    27" - been on it for about a decade now, its time to move up
    2k - not even a wide 2k, just 2k, in light of the new GPUs and upcoming CPUs, seriously ?
    VA - VA for gaming is hit and miss at best, usually its the miss despite marketing claims.
    Curved - preger flat,though this isn't necessarily a con as some people might prefer curved so I did not list it as such.
