However, they may suffer from narrower viewing angles and slightly slower pixel response times compared to IPS, potentially leading to subtle color shifts or ghosting during fast movement or multi-monitor setups. The monitor’s high resolution of 2560×1440 delivers sufficient screen space for most productivity tasks, though less than ultra-wide or 4K displays. The pixel density of 109 ppi provides adequately crisp text without requiring scaling, though pixel edges may become noticeable when sitting close or working with fine content. With a brightness level of None nits, this monitor may appear dim in bright office settings, making it less suitable for environments with strong ambient light.

The AOC CQ27G4ZH has limited color gamut coverage, which makes it unsuitable for color-accurate work such as professional design, printing, or video editing. The screen may fail to represent colors consistently across devices or in print. The 8-bit + FRC panel enables better-than-basic gradients, but with limited color space, it's still best suited for general use.
