Best Portable Monitors (2026): Add a Second Screen I’ve Tested

2026 年最佳便携显示器：我亲测过的第二屏幕推荐

Being away from the office means working on my laptop—and with that comes productivity slipping away into oblivion. The problem, for me at least, is the screen, or rather, the lack of them. A portable monitor solves this dilemma handily, working just like an external monitor setup does in the office, but with mobility also in mind. While larger portable monitors (especially multi-panel ones) may require a dedicated power connection, most can use your laptop’s USB port for all the juice they need.

离开办公室意味着要在笔记本电脑上工作，随之而来的往往是生产力的下降。对我而言，问题在于屏幕，或者更确切地说，是屏幕数量不足。便携式显示器可以轻松解决这一难题，它的工作方式与办公室的外接显示器设置相同，但同时兼顾了移动性。虽然较大的便携式显示器（尤其是多屏显示器）可能需要专门的电源连接，但大多数显示器只需通过笔记本电脑的 USB 端口即可获得所需的全部电力。

The portable monitor category is a very large one, occupied by both name-brand producers of laptops and desktop monitors as well as plenty of companies you’ve never heard of. For this buying guide, I evaluated 20 portable monitors from a wide range of manufacturers that represent price points ranging from $70 to nearly $700. I’m splitting my top recommendations across four major categories, with runners-up available for most of them.

便携式显示器市场非常庞大，既有知名的笔记本电脑和桌面显示器厂商，也有许多你可能从未听说过的公司。为了撰写这份购买指南，我评估了来自不同制造商的 20 款便携式显示器，价格从 70 美元到近 700 美元不等。我将我的首选推荐分为四大类，并为大多数类别提供了备选方案。

The Best Overall Portable Monitor: Arzopa Z3FC Portable Monitor

最佳综合便携显示器：Arzopa Z3FC 便携显示器

If you are simply looking for a single extra screen to have alongside your laptop and don’t need touch features, Arzopa’s Z3FC is the best pick for most users. This spacious 16.1-inch display costs just $136, but it’s absolutely loaded with features. Resolution of 2560 x 1440 pixels offers ample detail for any type of task whether work or leisure, and the screen unusually offers a whiplash-fast 180 Hz refresh rate. It’s got one of the brighter displays available across all portable monitors and an outstanding color-gamut rating, with a measured 99 percent of the sRGB space covered in my tests. Color quality is equally solid, with a 1.10 average accuracy rating measured.

如果你只是想为笔记本电脑增加一个额外的屏幕，且不需要触控功能，那么 Arzopa Z3FC 是大多数用户的最佳选择。这款宽敞的 16.1 英寸显示器仅售 136 美元，但功能极其丰富。2560 x 1440 的分辨率为工作或娱乐等各类任务提供了充足的细节，而且该屏幕还罕见地提供了 180 Hz 的超快刷新率。它是所有便携式显示器中亮度较高的产品之一，色彩表现也非常出色，在我的测试中覆盖了 99% 的 sRGB 色域。色彩质量同样稳健，平均色彩准确度评分为 1.10。

The hardware is simple but effective, with the monitor held up by a slim arm that flips out from the back of the display and connection options that include mini-HDMI and two USB-C ports. Because it draws just 13 watts, you don’t need an external power adapter if you connect via USB to your laptop. (Note that since HDMI connections don’t carry power, you’ll need to use one of the USB ports to connect to a power source if you choose that option.) The second USB port can be used to charge a phone or connect other USB peripherals, and the monitor even includes dual 2-watt speakers which, while not altogether useful, are at least better than nothing. Best of all is how portable the screen is: At just 1.64 pounds, it’s one of the lightest portable monitors on the market, especially at this display size.

其硬件设计简洁有效，显示器通过背部翻出的纤薄支架支撑，连接选项包括 mini-HDMI 和两个 USB-C 端口。由于它仅消耗 13 瓦功率，如果通过 USB 连接到笔记本电脑，则无需外接电源适配器。（请注意，由于 HDMI 连接不供电，如果选择该方式，则需要使用其中一个 USB 端口连接电源。）第二个 USB 端口可用于为手机充电或连接其他 USB 外设，显示器甚至还内置了两个 2 瓦的扬声器，虽然实用性有限，但聊胜于无。最棒的是它的便携性：重量仅为 1.64 磅（约 0.74 公斤），是市场上最轻的便携式显示器之一，尤其是在这个尺寸级别下。

Also consider: Espresso Lite 15 ($249) - What’s great about this monitor is its unique stand, which attaches magnetically to the back of the screen and allows you to position the display in any orientation on your desk—or raise it up so that it hovers above your laptop’s screen. It’s also got an incredible color gamut and solid brightness while drawing just 5 watts of power.

备选推荐： Espresso Lite 15（249 美元）——这款显示器的亮点在于其独特的支架，它通过磁吸方式附着在屏幕背面，让你可以在桌面上以任何方向放置显示器，或者将其抬高，使其悬浮在笔记本电脑屏幕上方。它拥有出色的色域和稳健的亮度，且功耗仅为 5 瓦。

The Best Portable Monitor With Touch: ViewSonic 2K Touch Portable Monitor TD1656

最佳触控便携显示器：优派 (ViewSonic) 2K 触控便携显示器 TD1656

If you need your second monitor to do double-duty as a drawing tablet or simply want to be able to tap on icons instead of relying on a mouse, the ViewSonic TD1656-2K offers the best bang for your buck. The 2K in the name evokes the monitor’s most impressive feature, 2560 x 1600 pixels of resolution across its vast, 16-inch, 16:10 wide-screen display. Brightness is exceptional, and contrast is very rich for a standard LED-backlit screen, but the unit’s colors are even more impressive. The 99-percent sRGB color-gamut coverage is outstanding, and the unit’s average 0.79 color-accuracy rating is the second best I’ve measured to date.

如果你需要第二台显示器兼作绘图板，或者只是想通过点击图标来操作而不是依赖鼠标，那么优派 TD1656-2K 是性价比最高的选择。名称中的“2K”体现了该显示器最令人印象深刻的特性：在 16 英寸、16:10 的宽屏显示器上提供了 2560 x 1600 的分辨率。它的亮度表现卓越，对比度对于标准的 LED 背光屏幕来说非常丰富，但其色彩表现更为惊人。99% 的 sRGB 色域覆盖率非常出色，且 0.79 的平均色彩准确度是我迄今为止测试过的第二好成绩。

The screen itself is largely free of frills, with two USB-C ports available: one to connect to your laptop, the other providing supplemental power if needed, though since the screen only pulls 12 watts of juice, you shouldn’t run into trouble without an additional adapter. Note that I was unable to use this second USB port for charging my phone or other peripherals. The touch features work great, either with a fingertip or with the responsive and included stylus. I was less enamored with the tinny 2-watt speakers—these could have just as well been jettisoned altogether—and didn’t love the convoluted and origami-like case-stand combo. While reasonably protective when wrapped around the screen, it’s difficult to fold the right way and, once you do have it configured properly, it offers only a couple of minimally adjustable viewing angles. It’s not exactly lightweight at 2.92 pounds (with the cover), but you are getting a very spacious view for the weight. At $380, it’s actually on the low-end of the price spectrum for portable touchscreens.

屏幕本身设计简洁，配有两个 USB-C 端口：一个用于连接笔记本电脑，另一个在需要时提供辅助供电，不过由于屏幕功耗仅为 12 瓦，通常无需额外适配器也不会有问题。请注意，我无法使用第二个 USB 端口为手机或其他外设充电。触控功能表现出色，无论是用指尖还是使用附带的灵敏触控笔。我不太喜欢那对音质单薄的 2 瓦扬声器——它们完全可以被省去——也不喜欢那种复杂且类似折纸的保护套支架组合。虽然包裹在屏幕上时具有合理的保护作用，但它很难折叠到位，而且一旦配置好，它仅提供几个可调节范围很小的视角。它 2.92 磅（含保护套）的重量不算轻，但考虑到它提供的宽广视野，这个重量是可以接受的。380 美元的价格在便携式触控显示器中其实处于较低水平。

Also consider: Espresso Pro 15 ($748) - The pro version of Espresso’s Lite features an amazing 15.6-inch screen with 3840 x 2160 pixels of resolution and breathtaking 10-bit color. It’s even brighter than the ViewSonic, which offers wonderfully deep and accurate hues and weighs about the same despite the added heft of Espresso’s bulky but versatile magnetic stand. The price is the only real dealbreaker.

备选推荐： Espresso Pro 15（748 美元）——这是 Espresso Lite 的专业版，配备了令人惊叹的 15.6 英寸屏幕，分辨率为 3840 x 2160，并拥有令人屏息的 10-bit 色彩。它比优派显示器更亮，色彩深邃且准确，尽管 Espresso 那笨重但多功能的磁吸支架增加了一些重量，但整体重量与优派相差无几。价格是它唯一的硬伤。

The Best Multiscreen Portable Monitor: Asus ZenScreen Duo OLED (MQ149CD)

最佳多屏便携显示器：华硕 ZenScreen Duo OLED (MQ149CD)

If you didn’t know any better at first glance, you’d guess it was a laptop, but flip the device open and you’ll see that Asus’s ZenScreen Duo offers two 1920 x 1200-pixel 14-inch monitors, connected via a hinge. To deploy, just unfold, extend the slim kickstand, and plug in a single USB-C cable to your laptop. Yeah, that’s it: Unlike most multi-panel monitors, the ZenScreen doesn’t require additional power, and its combined 13-watt power draw is easily managed by the USB-C port on most laptops. (An extra power port is available if your computer doesn’t have the juice.) The panels can be deployed verti…

如果你第一眼看去，可能会以为它是一台笔记本电脑，但打开设备后你会发现，华硕 ZenScreen Duo 提供了两块通过铰链连接的 14 英寸 1920 x 1200 分辨率显示屏。使用时，只需展开设备，拉出纤薄的支架，然后将一根 USB-C 线缆插入笔记本电脑即可。没错，就是这么简单：与大多数多屏显示器不同，ZenScreen 不需要额外供电，其 13 瓦的总功耗可以轻松由大多数笔记本电脑的 USB-C 端口满足。（如果你的电脑供电不足，它也提供了一个额外的电源端口。）显示屏可以垂直部署……
