Monitor Gaming

自 2017 年成立以来,Uperfect 公司已经发布了众多便携式显示器,适用于许多不同的使用领域。从 10 英寸到 18.5 英寸,只要涉及到尺寸,每个人都能找到适合自己的显示器。此外,它还销售各种触摸显示器和高质量 OLED 显示器,适合不想放弃高色彩准确度的创作者。

在本次评测中,我们将对 Uperfect UGame K5 游戏显示器进行更深入的了解。这是一款对角线长度为 17.3 英寸的便携式显示器。它的分辨率为 1,920 x 1,080 像素,刷新率高达 240 Hz,为游戏提供了良好的装备。制造商目前没有提供这款显示器的任何替代版本。与 Uperfect X Pro LapDock 不同的是,这款设备只是一款不带电池或键盘的外接显示器。Uperfect 游戏显示器可通过 HDMI 或 USB-C 接口连接。这意味着,该屏幕不仅可以与所有普通电脑连接,还可以与大多数知名视频游戏机连接。

Uperfect X Pro LapDock 附带以下配置:

  • Uperfect UGame K5 游戏显示器
  • 带支架选项的磁力套
  • 1x 迷你 HDMI 连接线
  • 2x USB-C 至 USB-C 连接线
  • 1x PD 30W 电源连接器

外壳和连接

Uperfect UGame K5 采用坚固的金属外壳,为 17.3 英寸显示屏提供了极高的稳定性。从外观上看,整个设备都是黑色的,薄薄的显示屏边缘给人一种非常现代的感觉。制造商没有为显示屏配备脚垫,而是使用一个磁性套筒将显示屏竖立起来。遗憾的是,你无法选择显示器的固定角度。

如果你不想使用这个套筒,也可以使用其他显示器支架。第三方卖家可能会提供大量其他解决方案。显示器背面已经安装了通过 VESA 支架安装屏幕所需的孔。Uperfect 还为 16 至 18 英寸的显示器提供了可调节支架。

在连接选项方面,UGame K5 配备了两个 USB-C 端口和一个 Mini HDMI 端口。如果不想使用内置扬声器,还可以通过 3.5 毫米插孔连接外置扬声器或耳机。所有这些接口都位于显示器的左侧,可以轻松连接。

Uperfect UGame K5 的 17.3 英寸屏幕分辨率为 1,920 x 1,080 像素。像素密度为 127 ppi。我们的测量结果显示,平均显示亮度为 245 cd/m²。这至少比 Uperfect X Pro 好。其测量的最大值为 266 cd/m²,不幸的是,低于其规格表中标注的 300 cd/m²。对于正常的日常使用来说,这应该还是足够的。加上其较低的黑色值,这足以保证显示器具有良好的对比度。我们只注意到一些模糊的小问题,最严重的是测试样本的底部边缘。这在日常使用中应该不会很明显。我们没有测量到任何 PWM,这意味着长时间使用也不会造成眼睛疲劳。除此之外,这款显示器的反应时间也很短,因此更适合游戏使用。

* ... smaller is better

我们的测量结果显示,sRGB 色彩空间的覆盖率很高。我们还注意到,P3 色彩空间的覆盖率超过了 80%。它覆盖了 80.4% 的 AdobeRGB 扩展色彩空间。相比之下,没有一个竞争对手能跟得上。说到照片或视频编辑,我们只推荐半专业用途的 Uperfect UGame K5。

主观而言,安装的显示屏画质不错。亚光显示屏不会产生任何镜像,也没有明显的颗粒。总之,显示器的 DeltaE 2000 测量值在交付状态下非常接近小于 3 的目标值。不过,它的竞争对手表明,在这方面还可以做得更多。我们无法通过手动校准来提高这些值。

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
8 ms ... rise ↗ and fall ↘ combined↗ 4 ms rise
↘ 4 ms fall
The screen shows fast response rates in our tests and should be suited for gaming.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 18 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (21 ms).
       Response Time 50% Grey to 80% Grey
12 ms ... rise ↗ and fall ↘ combined↗ 6 ms rise
↘ 6 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 22 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (32.9 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
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 8743 (minimum: 5 - maximum: 343500) Hz was measured.

IPS 面板在日常使用中提供了出色的画质。我们只注意到在平面和非常倾斜的角度下的色彩偏差,从四个角的图片中可以看出这一点。

发言人

Uperfect UGame K5 有两个 1 瓦的小型扬声器。不过,这只适合作为应急解决方案。声音可以听得很清楚,但低音明显不足。设备本身有一个 3.5 毫米插孔,可以连接耳机,我们建议您这样做。

耗电量

我们使用 Gossen Metrawatt Metrahit 能量万用表直接测定了该设备在插座上的耗电量。在待机模式下,我们测得的数值很低,仅为 0.1 瓦。根据我们的记录,开机时最低亮度下的功耗至少为 6.5 瓦。在全亮度下,电源必须提供 10.4 瓦的功率。因此,随机提供的 30 瓦电源绰绰有余。

评价:刷新率为 240Hz 的多功能显示器

Uperfect Game K5 是一款 17 英寸外接显示器。其技术规格表明这是一款完美的游戏显示器,这在我们的测试中得到了证实。该显示器拥有较短的反应时间和 240Hz 的刷新率--这些优点足以抵消显示器可能存在的一些缺点,如色彩空间覆盖率和 DeltaE 2000 值。

Uperfect UGame K5 是一款出色的游戏显示器,用途广泛。从价格上看,它可能很难说服潜在买家购买。

我们喜欢它纤薄边框的现代设计和出色的稳定性。但需要注意的是,它缺少一个内置脚垫。提供的套管可以作为应急之用,但您可能需要考虑使用第三方配件,以便通过 VESA 支架安装显示器。17 英寸显示器的像素密度为 1,080p,并不是最好的,尽管 WQHD 分辨率也是一个可行的选择。另一方面,1080p 的分辨率对于游戏来说通常已经足够,而且对硬件的要求通常也控制在一定范围内。

价格方面,Uperfect UGame K5 目前的售价约为 330 美元。这款显示器内部也有竞争对手,但它们大多不完全专注于游戏。USetup K3 也是一款 17 英寸显示器,但它的分辨率更高,达到 1440p,价格也低 100 美元。如果你不一定需要 240Hz 的刷新率,那么选择该机型或许能省下一些钱。

价格和供应情况

Uperfect UGame K5 可通过制造商网站购买。.目前,该显示器的售价为 330 美元。
