Uperfect UStation Delta 评测：配备双 15.6 英寸显示屏的便携式显示器扩展了桌面功能
Uperfect 从事便携式显示器业务已有数年时间，该公司目前拥有多种显示器产品，能够很好地满足用户的需求。该公司推出的 Uperfect UStation Delta 是一款奇特的便携式显示器，旨在以其卓越的多功能性提高日常工作效率。 那些经常更换工作场所且不想错过多屏幕优势的用户应该仔细了解一下：由于有两个垂直排列的 15.6 英寸显示屏，可用的数字工作空间得以大大扩展。一根线缆即可同时操作两个屏幕，避免了桌面上恼人的线缆杂乱问题。 由于这两个是独立的显示屏，因此可以同时使用两个独立的信号源。

机箱和端口
Uperfect UStation Delta 的制造质量与我们在测试其他 Uperfect 产品时看到的一样出色。尽管这只是一个原型，但其工艺无可挑剔，材料的选择也非常成功。设备的四周都是铝制外壳，使其具有超强的稳定性。坚固的支架也是由铝制成，即使完全折叠也能确保显示屏得到安全的支撑。
。
对于那些打算在家庭办公环境中使用显示器的用户，该设备还可以安装在 VESA 支架上。此外，交货包装中还包括一个保护套，可在运输过程中保护设备，并可用作必要电缆的袋子。
在连接方面，Uperfect UStation Delta 具有两个 USB-C 输入和两个迷你 HDMI 输入。此外，还有一个额外的 USB-C 端口，以便在需要时使用外部电源供电。只要电源和数据都使用 USB-C 连接，就不需要外接电源。
显示屏 - 双 15.6 英寸，1,080p
Uperfect UStation Delta 配备两块 15.6 英寸屏幕，每块屏幕的分辨率均为 1920 × 1080 像素。根据技术规格，屏幕的显示亮度应为 250 cd/m²。然而，我们只能测量到 226 cd/m² 的最大显示亮度。两块显示屏的平均亮度甚至更低，尽管亮度仍足以满足典型的室内使用需求。另一个值得一提的缺点是，在黑阶方面，两台显示器之间的差异很大。上部显示屏的对比度仅为 471:1，而下部屏幕的对比度为 1,026:1。两台显示器都存在混浊问题。我们的测试表明，在所有亮度设置下都没有出现 PWM，这很好，因为这减少了长时间使用可能造成眼睛疲劳的担忧。 在响应时间方面，Uperfect UStation Delta 的结果处于良好的中等水平。考虑到 UGame K5 的市场定位是游戏显示器，因此它能提供更好的响应时间也就不足为奇了。
注意：
只有连接到随附的电源适配器，才能达到最大显示亮度。在通过 USB-C 单电缆运行时，我们观察到最大显示亮度仅为 160 cd/m²。

色彩空间覆盖率
我们分别测量了两个屏幕的色彩空间覆盖率。差异相对较小，两款显示器的结果几乎完全相同。对于 sRGB 色彩空间，我们的测试结果显示覆盖率略高于 73%，这并不算高。同时，AdobeRGB 和 P3 色彩空间中只有略高于 50% 的色彩可以显示。对于半专业的照片或视频编辑来说，这还远远不够。相反，Uperfect 的色彩准确度只能满足基本的桌面扩展需求，用于文档编辑或互联网浏览。即使偶尔使用游戏机进行游戏也是可行的，因为这并不需要高色彩准确度。

色彩空间覆盖范围 - 下屏
在实际使用中，这两款显示器的图像质量都可以接受。很明显，Uperfect 显示器没有经过出厂校准。在出厂设置中，色彩的 DeltaE-2000 值偏高。
手动校准两台显示器后，我们大大降低了灰阶 DeltaE-2000 值。
相比之下，我们只看到色彩方面略有改善。在这方面，Uperfect UStation Delta 的数值没有低于 3。请注意，校准这些屏幕会使微弱的显示亮度变得更低。

发言人
Uperfect UStation Delta 自带扬声器。不过，这些扬声器只适合作为备用解决方案。语音清晰易懂，但低音明显不足。在 100% 音量下，扬声器的音量略高于 75 dB(A)。

评价：功能强大的实用扩展
乍一看，Uperfect UStation Delta 是数字工作场所的一大亮点。它配备了两个 15.6 英寸的屏幕，非常适合多任务处理。无论是阅读长篇文字、处理大型电子表格，还是浏览互联网，无需不断重新排列屏幕上的窗口，这种功能都非常出色，一旦你习惯了它，你就不想离开它了。
Uperfect UStation Delta 的精湛工艺和高品质材料的使用给人留下了深刻印象。它的连接性设计也很好，如果需要，可以在双显示屏上操作两个独立的设备。它的多功能性涵盖了广泛的应用领域，因为它可以连接笔记本电脑、智能手机、平板电脑甚至游戏机。不过，该显示器在色彩精确度方面存在很大的局限性，不适合专业照片和视频编辑。即使在半专业环境中，Uperfect UStation Delta 的可用性也很有限。
Uperfect UStation Delta 是移动工作空间的一个有前途的补充。提高色彩精确度和触摸屏将进一步增强该设备的吸引力。
另一个值得吐槽的地方是显示屏亮度有限。我们还希望 DeltaE-2000 的数值能更好。就目前的状态而言，Uperfect UStation Delta 还不够令人信服。630 美元对于一个数字工作空间扩展来说实在是太贵了。考虑到这里的测试装置只是一个原型，Uperfect 有可能会进行一些改进。因此，在最终产品发布之前，仍有可能进行修改。
1080p 的分辨率还不错。不过，值得注意的是，与 Uperfect UStation Delta 相似的双显示器已通过 Indiegogo 活动推向市场，它的名字叫 Lepow DualViews。Lepow DualViews 拥有两个 QHD 显示屏和触摸功能，可以提供更多的功能。
价格和供应情况
目前，Uperfect Delta 还没有在任何地方销售。Uperfect 打算不久后在 Kickstarter 上发起募捐活动，为早期参与者提供诱人的优惠。该设备目前在 Uperfect 网站上的售价为售价为 630 美元。这个价格是否会保持不变还不确定。对这款显示器真正感兴趣的人应该定期访问该网站。
