AOC C27G2Z 27 curved frameless ultra-fast gaming monitor review


The monitor has a matte black chassis with red streaks, so even if its an aging gaming monitor color scheme, it doesn’t look tacky from the front. The display is bezel-free on three sides, but you will still see panel borders when its in use.

The plastics feel sturdy enough to withstand a few hits while the panels fit each other perfectly without uneven seams. The monitor also doesn’t wobble once fully assembled, so you can be assured that it won’t shake or rumble when your inputs become a bit more intense.


The back has a simple design similar to other AOC monitors we’ve tested. There’s no RGB lighting, but there’s a small hole in the back of the stand for cable management


There are no USB ports or built-in speakers. Underneath the panel’s center is an input panel with two HDMI 2.0 and a single DisplayPort 1.2. A 3.5mm audio output supports headphones or powered speakers.

  • DisplayPort 1 (DP 1.2)
  • Mini DisplayPort No
  • HDMI 2 (HDMI 2.0)
  • DVI No
  • VGA No
  • DisplayPort Out No
  • USB No
  • USB C No
  • Analog Audio Out 3.5mm 1
  • Microphone In 3.5mm No
  • Digital Optical Audio Out No
  • Analog Audio Out RCA No
  • Power Supply Internal


The AOC C27G2Z includes a flexible stand that provides height, swivel, and tilt adjustments so you can always get a comfortable view. You can’t pivot the screen since it isn’t ideal due to its curvature like most similar variants in the market. However, it is VESA-mountable so you can simply swap out its stand with a more flexible option that suits your needs.


The AOC C27G2Z sports a 27-inch VA panel with a 1920 x 1080 resolution, a whopping 240Hz refresh rate, and a 0.5ms MPRT response time. The backlight tops out at 300 cd/m2, while the contrast ratio sits at 3000:1 like most VA panels. VA screens can sometimes be less accurate than IPS, but its advantage in its contrast ratio means you get richer images and deeper blacks.

Refresh rate

The AOC C27G2Z’s pixel response time is fantastic for a VA monitor thanks to its high refresh rate. The screen barely shows blurring at its maximum, but some persistence can still appear in a few instances. Setting the overdrive to its middle to highest levels can help, so we recommend playing around with the settings first to get a suitable output.


The AOC C27G2Z is a FreeSync monitor, but its also compatible with Nvidia’s G-Sync compatibility mode. This makes it a great option if you regularly upgrade a GPU since you won’t be stuck with one brand if in case the other releases something better performance and price-wise. Input lag sits at 3ms at 240Hz, so delays won’t be an issue during your gaming sessions.

AOC C27G2Z 27 curved frameless ultra-fast gaming monitor performance review

The AOC C27G2Z is capable of eye-popping color since it can comfortably exceed 100% of the sRGB gamut or up to 91% in DCI-P3.  Default accuracy it’s at DeltaE 1.69 which is fantastic for a gaming monitor, so you won’t need to calibrate it once it is out of the box. The color temperature slightly exceeds the 6500K point, but it won’t be enough to skew the great hues of the screen.

Contrast is always our top consideration when reviewing monitors and any display with a VA panel already has an advantage. You can expect at least double the dynamic range of an IPS or TN screen and sometimes even triple, like the AOC CQ27G2. Though it doesn’t include HDR, it delivers a very high contrast ratio over 3600:1 right out of the box. It is a bit less bright than most of its competition at a rated 250 nits but its killer black levels more than make up for that.

Gaming features include a three-level overdrive and motion blur reduction courtesy of a backlight strobe. Like most gaming monitors, you must pick between the strobe and Adaptive-Sync; you can’t use them together. There are 20 levels of blur reduction controlled by a slider; less blur means less light output. You also get a frame rate counter and an aiming point.

-Not great contrast-Thick BezelsAdvertisement

Perhaps a little obvious, but packing lots of top-end features into a display means it’ll come with a high price tag. The Asus ROG Swift PG27UQ is an incredible display but it doesn’t come cheap. That money does net you more features than any other display here and perhaps that’s enough to set it apart. As well as the ridiculously clear, bright and detailed images that the PG27UQ’s 4K and HDR-enabled 27-inch display shows off, this monitor also incorporates Nvidia G-Sync tech, making this an absolute behemoth of a screen. Though we do wish the contrast was slightly better on this nearly perfect screen. 

On the back, it’s a bit lean on the connections, but you should have everything you need: present are an HDMI 2.0 input, DisplayPort 1.4, 3.5mm audio, and two USB 3.0 ports. It’s also an incredibly well-designed bit of kit with the stand effectively funneling cables, as well as looking cool. I especially like the ROG eye that shines on the surface wherever you put the monitor. 

The list price is very high, so it might well put people off, but it will not disappoint those who take the plunge.
