The portable monitor bought for a MacBook also turns phones and handhelds into workstations

The 16-inch ARZOPA Z1RC can connect to Galaxy phones, Steam Decks and Apple devices, extending its usefulness well beyond laptop work , though powering it can drain a phone’s battery.

An inexpensive portable USB-C monitor can do more than simply add a second screen to a laptop. In this case, a low-cost 16-inch model was bought primarily to expand MacBook Pro workspace, but it quickly proved useful with a wider range of devices. The monitor in question is the ARZOPA Z1RC, a 16-inch portable panel with a 2,560 x 1,600 resolution, a thin chassis and a built-in kickstand, according to ARZOPA’s product page.

Its appeal is straightforward: it is light enough to carry, simple to connect and designed for situations where a full desktop monitor would be impractical. ARZOPA lists the display as a portable 16-inch unit with USB-C connectivity, while the article notes that it includes two USB-C ports and a mini HDMI port, plus integrated speakers that are best treated as a backup rather than a primary audio solution. That combination makes it a flexible travel accessory rather than a conventional desk-only screen.

The most striking use case is turning an Android phone into a desktop-like workstation. Samsung’s support documentation explains that DeX can project a desktop-style interface to an external display on compatible Galaxy devices, while Google’s Android help pages describe desktop windowing and connected-display features for supported phones. In practice, that means a USB-C monitor can do more than mirror a handset; it can open the door to resizable app windows, multi-window workflows and, on some devices, a pointer-driven interface for more productive use.

There is a caveat, however: power matters. If the monitor is not separately powered, the phone supplying the video signal can end up doing the heavy lifting, which will drain the battery more quickly. That is an important trade-off for anyone expecting to use a portable display for extended work sessions away from the mains. It is also why a display that looks like a simple accessory may function better as part of a planned portable setup than as an on-the-go convenience item.

The same logic applies to gaming handhelds. Valve’s Steam Deck specifications confirm that the device supports USB-C with DisplayPort 1.4 Alt Mode, which allows video output over a single cable in suitable setups. That means a dock is not always required just to get a handheld onto a bigger screen, although separate power for the monitor remains advisable if battery life matters.

Apple devices are a little different. Apple’s documentation says an iPhone or iPad may mirror content to a connected display, while compatible iPads can support a more extended external-display experience. The practical result is that a portable USB-C monitor can be used for watching video, showing photos or working with a larger canvas, depending on the model and software. The underlying theme is the same across platforms: a compact monitor bought for laptop use can end up becoming one of the most versatile pieces of kit in a bag.
