结论物美价廉的 UHD 显示器
华硕 ROG Strix XG27UCS 是一款经济实惠的 4K 游戏显示器，其高画质和自适应同步技术给人留下了深刻印象。UHD 分辨率非常清晰，超过 400 cd/m² 的最大亮度足以满足室内使用。可显示的色彩空间也达到了大型显示器 P3 标准，色彩显示正确。该显示器配有可旋转和高度可调的支架，但不提供集成扬声器，USB-C 电源功率仅为 15 瓦，不足以为笔记本电脑充电。连接有点有限，待机模式下的功耗有时过高。不过，没有发热问题。总的来说，这款显示器凭借 160 Hz、HDR 和快速响应时间提供了非常好的游戏体验，而且目前的价格约为 350 欧元，就其性能而言也非常实惠。
Pros
Cons
功能和连接性
ROG Strix 游戏显示器提供了一个可旋转和高度可调的支架，还为智能手机提供了一个架子。不过，端口数量有点少。只有 1x DisplayPort 1.4（160Hz@4k）、1x HDMI 2.1（160Hz@4k）、1x USB-C with DisplayPort 1.4（160Hz@4k，15 瓦 PD）和一个用于扬声器的 3.5 毫米插孔输出。华硕设备不提供集成扬声器。遗憾的是，15 瓦的 Power Delivery 功率也不足以为笔记本电脑充电。此外，它还没有集成 USB 集线器。
图像质量
就其价格而言，ROG Strix XG27UCS 的图像质量令人印象深刻。27 英寸屏幕的分辨率为 3840x2160，画质细腻，得益于液晶面板，文字显示也非常清晰。磨砂表面在防眩光和清晰色彩之间实现了很好的折中。超过 400 cd/m2 的最大亮度也足以应对明亮的室内环境，但当然赶不上昂贵的 HDR 机型的高亮度。
在测试中，色彩准确度令人满意。显示屏可以限制在 sRGB 和 DCI-P3 范围内，也可以在广色域模式下使用全色彩空间。

显示屏没有使用 PWM，我们也无法用测量探头检测到任何其他闪烁。
Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM not detected |  | ||
In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8377 (minimum: 5 - maximum: 343500) Hz was measured. | |||
显示屏的响应时间取决于菜单中的 "OD"（超速）设置。您可以在 0 和 20 之间进行选择。0 和 10（标准设置）之间几乎没有差别。最高设置为 20 时（见下文），可以看到明显的超速。在这里，您可以获得明显更快的响应时间，但也会出现重影和像素过冲等常见问题。

耗电量
在使用 Metrahit Energy 对插座进行的 SDR 模式功耗测试中，我们测得的功耗在 14 瓦（0% 亮度设置，53 cd/m2）和 34 瓦（100% 亮度 - 441 cd/m2）之间。亮度为 50%（可用 256 cd/m2）时为 23.7 瓦。华硕在此规定为 26 kWh / 1000h（能效 F），即平均 26 瓦。在 HDR 模式下，华硕规定为 45 千瓦时/1000 小时（= 46 瓦）。这些数值并不突出，但很常见。
待机/关机模式下的功耗更为突出。用开关关闭设备时，功耗仅为 0.17 瓦。在待机模式下，耗电量取决于设备未开启的时间长短。刚使用时，耗电量高达 12.6 瓦。之后（约 1 小时后测量），功率仍为 3.5 瓦。又过了几个小时，功率降至 1.4 瓦。因此值得手动关闭显示器。
温度
在环境温度为 24°C 时，经过长时间使用后，在测量温度为 37°C 时，发热量仍在限制范围内，无需担心。
摘要
华硕 ROG Strix XG27UCS 是一款经济实惠的 4K 游戏显示器，具有良好的功能、真彩色面板，几乎没有任何缺点。通过 USB-C 接口供电的 15 瓦电源和亮度传感器的缺失是日常使用中的主要缺点。自适应同步、160 Hz、HDR 和快速响应速度会让游戏玩家感到满意，而低廉的价格也会让他们感到欣慰。
