AOC G2770PF 27-inch FreeSync Gaming Monitor Review

Brightness And Contrast

To read about our monitor tests in-depth, please check out Display Testing Explained: How We Test Monitors and TVs.Brightness and Contrast testing is covered on page two.

Uncalibrated – Maximum Backlight Level

We've reviewed a fair number of FreeSync monitors of late so the newest models are here on the charts today. From Asus we have the PG279Q G-Sync, MG278Q FreeSync and MG279Q, also FreeSync. Acer is represented by the curved XR341CK and the value category is borne by Nixeus' NX-VUE24A. There are three each of TN and IPS monitors in the mix though it doesn't seem like either tech has any real advantage except for IPS' better viewing angles.

The G2770PF exceeds its claimed brightness of 300cd/m2 by a comfortable margin. All the screens here are comparable in output except the Nixeus, which has a less-powerful backlight. The AHVA screen used in Asus' PG279Q has the greatest output by a nose. It's also the most expensive display here.

Black level results cover a wide range but the G2770PF is in the middle group. Dark content is rendered richly with clear detail and no light bleed in our press sample. You can lower this number with the dynamic contrast or Shadow Control options but then some detail will be lost.

Contrast comes in at over 1000:1, which puts the AOC in very good company. Only a VA panel can significantly raise the bar in our tests. Remember that AHVA (used in the PG279Q) is a variation of IPS; not to be confused with AMVA.

Uncalibrated – Minimum Backlight Level

AOC has chosen a bright level for the minimum backlight setting. It's a little too much light if you're playing in a totally dark room. We'd like to see a number below 100; preferably around 50cd/m2. That will allow longer work and play sessions before fatigue sets in.

The bright backlight raises the minimum black level and sends the G2770PF to last place in this test.

However, contrast remains rock-solid consistent at 1073.2:1, which is almost identical to the max number. Regardless of settings, the image shows great depth with rich blacks, bright highlights and good dimensionality.

After Calibration to 200cd/m2

Calibration has a positive impact on black levels and vaults the G2770PF up to second place. Considering that it's value-priced, this looks like a decent panel so far.

Contrast is unchanged mainly thanks to balanced RGB sliders that start at center-range and decent though not stellar gamma tracking. We still recommend using our settings or calibrating for the most natural image with maximum dynamic range and accurate color.

ANSI Contrast Ratio

We don't see many screens exceed 1000:1 in the ANSI test. Our sample shows excellent screen uniformity and great intra-image contrast. The G2770PF is pretty much beyond reproach in these tests but as we moved into our grayscale and color benchmarks, we found a few minor issues.

    I don`t understand the 27" 1080p market, most of the guys who buy these monitors instantly regret it and sell them for cheap on the second hand market. In phones they don`t know how to cram more pixels on to a little screen while on PC they don`t know how to make them bigger ...

    I could live with 1080p at 27 inches. Hell, I've been using a 42 inch TV for years now and I honestly have no complaints with the pixel density, which is much worse. I probably would struggle to deal with the ghosting though from the lack of overdrive on this panel over 60Hz.

    My current freesync monitor had a firmware bug that prevented overdrive from being enabled with freesync turned on, and the ghosting was atrocious. I had to send it in to get the firmware updated, and the monitor has been excellent ever since.

    1080 at that size is a bit nasty. Save a bit a get 1440 at this screen size - better, just better.

    I looked at Asus 27" 1080 TN panel a couple of years ago in store and it looked great. I just wish gsync was same price.

    I'm sticking with the 24" Aoc 144hz Freesync model. I don't see the point of spending more on a bigger screen.
