Before buying a portable monitor, confirm that your laptop can send video through the connection you plan to use, that the monitor can get enough power, and that its stand suits your setup. USB-C alone does not guarantee video output; check the exact laptop and monitor specifications, then verify the cable, display mode, and physical support.
Start with the laptop: can its USB-C port output video?
USB-C describes the connector shape, not every function the port supports. Look up your computer’s exact model and check whether the relevant USB-C port supports DisplayPort Alt Mode, Thunderbolt, USB4 display output, or the specific video feature required by the monitor. ASUS likewise advises checking whether the computer’s USB-C port has a DP video function: ASUS USB-C portable-monitor support.
Next, confirm that the laptop’s video output supports the monitor’s required resolution and refresh rate. A port may carry video without supporting every display mode the monitor offers.
Check the complete connection path
For USB-C video, the host port, monitor port, and cable all need to support the required functions. DisplayPort notes that “DisplayPort, USB data, and USB Power Delivery can all be carried simultaneously through the same USB Type-C connector and cable.” That does not mean every USB-C port or cable supports all three. See the DisplayPort FAQ for the connection capabilities and adapter options.

If the laptop supports USB-C DisplayPort output but the monitor takes HDMI, a compatible USB-C-to-HDMI adapter may provide a path between them. Check the adapter’s compatibility and supported display mode as well as the devices’ specifications.
When HDMI is the better option
HDMI can be a straightforward alternative when the laptop has a compatible HDMI output and the monitor has an HDMI input. Compare the documented HDMI versions and the resolution and refresh rate supported by both devices; HDMI ports do not all offer identical capabilities. HP’s HDMI version guide explains why the version matters.

Check the connector size before ordering a cable. Some portable monitors use mini-HDMI rather than full-size HDMI. MSI lists a mini-HDMI cable among the box contents for the PRO MP161E6, illustrating why the exact model’s port and included accessories matter: MSI PRO MP161E6 specifications.

Check the portable monitor’s required power input, its port arrangement, and whether it supports power pass-through. If it needs a separate power connection, account for that cable and any required adapter.

For pass-through charging, compare the monitor’s stated maximum output wattage with the laptop’s charging requirements. Do not assume a monitor will replace the laptop’s charger unless its output is sufficient for that computer. ASUS recommends checking the specific product specifications for the supported pass-through wattage: ASUS USB-C pass-through charging guidance. ViewSonic also identifies host Alt Mode support, an adequate cable, and external power as setup checks: ViewSonic portable-monitor setup guidance.
