配备 240 Hz IPS 面板、G-Sync 技术及精准色彩的 27 英寸显示器：KTC H27E6S 评测
不仅面向游戏玩家。
售价240欧元的KTC H27E6S是一款配备G-Sync技术、刷新率达240 Hz的高速27英寸QHD显示器。不过，得益于其哑光屏幕表面和精准的色彩还原，它也适用于游戏以外的其他用途。Andreas Osthoff, 👁 Andreas Osthoff (translated by DeepL / Ninh Duy) Published 🇺🇸 🇩🇪 ...
结论：价格实惠的27英寸240 Hz显示器
在测试中，KTC H27E6S 表现令人印象深刻。其 27 英寸 IPS 面板拥有高达 240 Hz 的刷新率和快速的响应时间，无论在 PC 还是游戏主机上，都能轻松应对节奏最快的射击游戏。 然而，HDR 游戏体验并不理想，因为 IPS 面板的亮度不足以呈现出令人满意的 HDR 效果。
得益于出色的亮度、哑光屏幕表面以及无 PWM 闪烁的特性，这款显示器也非常适合办公生产力工作，尤其是屏幕支持旋转至竖屏模式。 随附的支架提供了丰富的调节选项，但在背光灯效方面则较为匮乏。
即使使用出厂设置，H27E6S 在 sRGB 色彩空间内也能呈现准确的色彩还原，这也使其适合图像编辑。 总体而言，这是一款性价比不错的全能型显示器。不过，如果您只是偶尔玩游戏，那么那些刷新率较低但功能更丰富的竞品（例如支持 USB-C 电源传输或 KVM 切换功能的产品）可能会更具吸引力。
Pros
Cons
KTC推出的H27E6S是一款价格亲民的27英寸显示器，采用IPS面板并具备240 Hz刷新率，主要面向游戏玩家。不过，得益于其精准的色彩表现和哑光面板，该显示器也适用于办公生产力任务。
规格

| 输出接口 | ，3.5毫米音频接口 |
设计与功能
双色机身外观精美，整体做工也相当出色。尤其是底座，非常稳固，且提供丰富的调节选项。其机械结构运转非常顺畅，显示器还可以旋转 90 度以竖屏模式使用。我们在下方的图片中展示了调节范围。
后面板上部中央附近还设有发光徽标，其颜色可自定义。显示器重量为5.98千克（含底座），而外置的65瓦电源适配器则额外增加427克。 包装盒内还附带了一根 DisplayPort 线缆。此外，通过其 100 x 100 毫米的 VESA 安装孔，该显示器可轻松安装在其他支架或显示器臂上。
屏幕菜单通过显示器背面的摇杆（右下角）进行控制，该摇杆同时也兼作电源按钮。 操作界面直观易用，我们在测试过程中未遇到任何问题。接口均位于机身背面，包括两个HDMI接口和两个DisplayPort接口。宣传的240 Hz刷新率仅通过DisplayPort接口支持；若通过HDMI连接，刷新率则限制在144 Hz。
该显示器还支持 G-Sync 和 FreeSync，对主机游戏玩家同样颇具吸引力。如下图所示，PS5 Pro 在 QHD 分辨率和 120 Hz 刷新率下运行流畅，未出现任何问题。不过，该显示器不配备 KVM 切换器，也不支持 USB-C 电源传输功能。
显示屏——240 Hz IPS屏
这款27英寸IPS显示屏的分辨率为2,560 x 1,440像素（16:9），其哑光面板的主观画质非常出色。 所有内容均显示清晰锐利，色彩鲜艳生动。得益于高刷新率，动态画面也显得格外流畅。响应时间在IPS面板中表现良好，且通过过驱动设置进一步优化。高亮内容不会出现颗粒感，且无PWM闪烁现象，这使得该显示器非常适合工作使用。
在使用专业 CalMAN 软件进行的测试中，该面板的亮度轻松超过了宣传的 400 cd/m²，平均亮度略低于 492 cd/m²。不过，亮度均匀度仅为 81%，表现并不特别理想。 黑电平略高，为0.39 cd/m²，但最大对比度仍达到约1,200:1，超过了制造商规定的1,000:1。 不过，最低亮度约为 90 cd/m²，略显偏高。尽管屏幕支持 HDR 内容（HDR400），但与 OLED 或 Mini-LED 显示屏不同，IPS 面板的亮度不会进一步提升。

内置的 sRGB 配置文件开箱即用即可提供准确的色彩，尽管其灰度偏差相对较高。 此外还存在轻微的绿/蓝偏色，且色温偏冷。选择此设置是为了提高最大亮度。不过，通过我们自己的校准（相应的配置文件可在上方框中免费下载），我们可以显著提升图像质量。 灰度和色彩偏差均降至极低水平，色偏也完全消失。这使得该屏幕非常适合在sRGB色域内编辑图像和视频，且该色域覆盖率达到100%。不过，校准后最大亮度会降低约35 cd/m²。

尽管技术规格中未提及扬声器，但在下边框中央确实有一个扬声器模块。不过，它真的只应被视为最后的选择，因为其音量并不大，且声音听起来极其单薄。

结论——一款优秀的IPS显示器，不仅适合游戏玩家
总体而言，KTC H27E6S 是一款优秀的 IPS 显示器，凭借其高刷新率和快速响应时间，特别适合游戏使用。不过，那些主要为了工作而选购 IPS 显示器的用户可能会觉得缺少 USB-C 电源传输或 KVM 切换器等功能。
