A portable monitor is a second screen for a laptop, console or handheld. Most run both picture and power over a single USB-C cable — provided your device outputs video over USB-C (DisplayPort Alt Mode), which most modern laptops and many phones and handhelds do. Devices without it can usually still connect over Mini HDMI, with a separate USB cable or adapter for power. The right choice depends on what you plug it into.
Resolution. 1080p (Full HD) is sharp at 15.6 inches for documents, browsing and most games, and it is easier for laptops and handhelds to drive. 4K (3840 × 2160) shows visibly finer text and detail — better for photo work, spreadsheets and media — but needs a device that can output 4K over USB-C or Mini HDMI.
Refresh rate. 60Hz is standard for work. 120Hz makes motion smoother in games and fast scrolling, and matters most if your console or PC can actually output 120 frames per second.

Power. Most portable monitors draw power from the same USB-C cable as the picture. Models with a built-in battery, like the UPERFECT UTouch G16, can also run away from a plug. Our current range is in Gaming & Desk Setup.
