Can HDMI Power a Portable Monitor?
In the era of digital nomads, hybrid work, and mobile gaming, portable monitors have become essential tools. Whether you're extending your laptop screen or hooking up your Nintendo Switch, one common question arises: Can HDMI power a portable monitor?
Let’s dive into the technical details, explore your options, and share practical setups that actually work in 2025.
Can HDMI Power a Portable Monitor?
In most cases, the answer is NO. While HDMI carries video and audio signals, it does not provide enough electrical power to turn on or run a portable monitor. Most portable monitors need around 5V/2A or higher, which HDMI ports on laptops or game consoles cannot deliver.
What is HDMI?
HDMI stands for High-Definition Multimedia Interface. It’s a widely used standard for transmitting:
- High-quality video
- Digital audio
But here's the catch: HDMI is not designed to deliver power.
It was never intended to function like USB ports or chargers. That’s why most HDMI connections cannot power external monitors—especially high-resolution portable ones.
When Do I Need HDMI?
HDMI still plays an important role when:
-
Your laptop doesn’t support USB-C video output
-
You want to connect to game consoles
-
You use older devices or desktop PCs
For example, the Arzopa Z1FC portable monitor supports both USB-C and mini HDMI, giving you the best of both worlds.
Typical Setup of Portable Monitor: HDMI + USB Power
If your portable monitor has an HDMI input (such as mini HDMI or micro HDMI), it will almost certainly require a second cable for power. A common dual-cable setup looks like this:
| Cable Type | Purpose |
|---|---|
| HDMI to HDMI | Transmits video/audio |
| USB-A to USB-C (or Micro-USB) | Provides power (from laptop, wall adapter, or power bank) |
This two-cable system is especially common with gaming setups like:
-
PlayStation 5 + Portable Monitor
-
Nintendo Switch + Portable Monitor
-
Mini PC + Monitor for travel
What’s the Alternative to HDMI Portable Monitors?
Unlike HDMI, which only transmits video and audio, USB-C with DisplayPort Alt Mode and Power Delivery offers a more advanced and streamlined solution—it can handle video, audio, and power through a single cable. This means fewer adapters, less cable clutter, and a cleaner, more efficient setup. For users who prioritize portability, simplicity, and compatibility with modern devices, USB-C portable monitors are undoubtedly the smarter choice in 2025, especially for laptops, tablets, and newer smartphones that support USB-C output.

Conclusion
In conclusion, while HDMI is a great solution for transmitting video and audio signals, it simply cannot provide enough power to operate most portable monitors on its own. That means if you’re using an HDMI connection, you’ll also need a secondary power source, typically via USB-A or USB-C. For the most convenient and flexible experience, your best option is to choose a monitor that supports both HDMI and USB-C connections.

FAQs
Can I use a portable monitor with only one cable?
Yes, if it's a USB-C monitor with power delivery and your device supports it.
Can I power my monitor with a power bank?
Yes! Just make sure it delivers at least 5V/2A output.
Will HDMI 2.1 support power in the future?
Not currently. HDMI is not designed for power delivery.
Does HDMI carry audio?
Yes, HDMI does carry audio along with video through a single cable. It is designed to transmit high-definition video and multi-channel digital audio, including formats like Dolby TrueHD and DTS-HD, making it ideal for connecting devices such as laptops, gaming consoles, or Blu-ray players to TVs, monitors, or projectors. As long as the connected display has built-in speakers—or is linked to an external audio system—both video and audio can be delivered seamlessly via HDMI, eliminating the need for separate audio cables.
