27" Dell S2721D 游戏监控性能基准测试

显示器有一个VESA安装座. Dell S2721D 具有显示端口，这对于NVIDIA卡与AMD FreeSync一起使用至关重要. 对于图形颜色质量， Dell S2721D 具有出色的 8 -bit色深，从而产生更平滑的渐变和更准确的色彩. 借助AMD FreeSync支持，该显示器兼容AMD和NVIDIA显卡. 在像素密度方面， Dell S2721D 具有优异的 109 像素/英寸密度，从而使文本和图像质量更加清晰. 监视器面板具有良好的视角，并提供比TN面板更好的对比度和颜色. Dell S2721D 是一个相对较新的监视器. Dell S2721D 的最小响应速率为 9.8 ms，这可能会导致重影效应. 图形要求严格的游戏可能导致帧丢失超出 48 Hz的正常刷新率. Dell S2721D 的亮度低于其他显示器. Dell S2721D 的总输入滞后为 27.9 ms，这在竞争中是不好的. 监视器的对比度为 1015 ：1. Dell S2721D 的最大刷新率为 75 Hz，这对于竞争性游戏中极快的帧速率而言可能太低. 对于平均响应率， Dell S2721D 得分 17.4 ms，由于与高刷新率的无效同步而导致运动模糊.
