AOC G2770PF 27-inch FreeSync Gaming Monitor Review

Color Gamut And Performance

For details on our color gamut testing and volume calculations, please click here.

In its default state, the G2770PF tracks the color points fairly well, though blue is over-saturated. Luminance is reduced to compensate so the resulting error isn't too high. Also of concern are the red saturations from 20 to 80 percent. They fall a little short of target, which means middle red tones will lack that last bit of pop. Like the grayscale results above, this isn't a bad chart but other screens perform better.

The sRGB preset evens out color luminance a bit but there are no changes to the CIE chart or the overall error level. We'd still like to see red and blue come closer to their targets but there is no way to fix the issue without a color management system.

Calibration again produces the best possible chart. Most errors are now below the 3dE threshold, which means they're invisible to the naked eye. The secondary colors are also on-point with regard to hue. The only issues remaining are the red and blue saturation levels. Luminance is now spot-on at every point except 100 percent where red is a bit too low. It should be raised to offset its under-saturation.

Now we return to the comparison group.

Since the majority of our measured color points are close to target, the calibrated average error is well under the visible threshold. It does however finish in last place compared to the other gaming screens. In fairness, several of them are expensive premium products but we've seen better accuracy from other AOC displays.

Gamut Volume: Adobe RGB 1998 And sRGB

The G2770PF's sRGB gamut volume comes up a tiny bit short mainly due to an under-saturated red primary. For gaming this test doesn't show any problems but if you plan to use it as a proofing monitor, a software LUT will be necessary to ensure accuracy.

    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.
