This monitor uses a VA panel, and its best feature is the high static contrast ratio of 3,000:1. In reference, TN and IPS panels typically have a contrast ratio of just 1,000:1.
The effect is deep blacks, bright whites and a slightly more prominent partnership between the darkest and brightest shades that allows for an enjoyable viewing experience – particularly in dark rooms.
After that, VA panels often have good representation of colours. The colors are much more vivid than TN panels but not as punchy as you can see on IPS ones.
Nevertheless, for more vivid and lifelike colors, the AOC CQ27G1 uses a wide color gamut backlight spanning 122 percent of the sRGB color space. Although this puts the image quality difference between the IPS and VA to a close, IPS displays are often stronger when it comes to image fidelity and clarity.
Eventually, this monitor’s peak luminance maxes out at 250-nits which might sound too weak but will be more than enough in regular viewing conditions.
The greatest downside to VA panel screens is the level to pixel reaction times.
Although manufacturers say ‘4ms’ gray to white pixel transfer period for VA displays, the transformation between very dark pixels is generally slightly slower.
It causes visible black smearing in fast-paced games with fast-moving items and can be very frustrating if you are a serious FPS player.
It’s basically marginal for casual gamers and other game types, so you possibly won’t really find it unless you really are hunting for it.
Remember that pixel reaction delay is not the same as input lag-the time it takes for the device to respond and show your commands is input and output lag. All monitors in this list have a low input lag (under 6ms) which results in an imperceptible 144Hz delay.
