You work in a bright room and need a bright screen

What owners like

Smooth, fast motion in games at 144Hz
Strong contrast and accurate color in sRGB mode for the price

Good value for a 27 inch high refresh screen

Common complaints

Brightness is low, and the Boost overdrive mode makes the screen much dimmer
1080p looks less sharp on a 27 inch screen than on smaller monitors
No speakers, no USB hub and no HDR
The 1ms figure is MPRT, not a gray to gray response time

What it does

A 27 inch curved 1080p gaming monitor with a VA panel, a 144Hz refresh rate and a height adjustable stand. AOC now also sells the C27G2 as its newer version.

Curved VA panel with high contrast, so dark scenes look deep rather than gray
144Hz refresh with FreeSync for smoother motion in fast games
Stand adjusts for height, tilt and swivel, which is unusual at this price
Thin bezels on three sides, so two units sit side by side neatly
Low power draw for a 27 inch monitor

A good fit for someone who wants smooth 144Hz gaming on a budget and likes a curved screen with deep blacks. The trade-offs are a 1080p resolution that looks soft at 27 inches and modest brightness, which drops sharply in the fastest overdrive mode.

How it compares

AOC C27G2The newer version: 165Hz, a tighter 1500R curve and HDMI 2.0, with the same 1080p VA formula.$

AOC CQ27G2Pick it if you want a sharper 1440p image at 27 inches and your graphics card can drive it.$$
