This guide is your definitive solution to that problem. Whether you’re a gamer trying to use your Xbox with a high-performance DisplayPort monitor or a professional setting up dual displays in the office, we’ll walk you through the exact tools and steps you need to make HDMI-to-DP work—without the frustration. Let’s dive in.
Ever tried connecting your HDMI laptop or gaming console to a monitor that only has a DisplayPort input—and nothing happened? You’re not alone. While HDMI and DisplayPort are both popular video standards, they don’t speak the same language natively.
Overview
HDMI and DisplayPort are two of the most commonly used video output standards in the digital world. HDMI ports are found on nearly every laptop, desktop, gaming console, and media device, while DisplayPort is widely adopted in professional monitors and business workstations for its high bandwidth and performance.
While most users are familiar with converting DisplayPort to HDMI, the reverse—HDMI to DisplayPort—is less straightforward and requires a specific solution. If your monitor only has a DisplayPort input and your device outputs HDMI, you will need an HDMI to DisplayPort adapter plus a DisplayPort cable.
What Is an HDMI to DisplayPort Adapter?
An HDMI to DisplayPort adapter is an active converter designed to transmit both video and audio signals from an HDMI source (like a laptop, gaming console, or streaming device) to a DisplayPort input on a monitor or projector.
Unlike passive cables, this adapter contains a built-in chipset that converts HDMI’s TMDS signal into DisplayPort’s LVDS protocol. Additionally, it requires USB power to function, especially for resolutions like 4K at 60Hz.
Example Use Case: Connecting an Xbox Series X to a gaming monitor with only DisplayPort input.
HDMI to DP Adapter vs. DP to HDMI Adapter
It is critical to understand that these adapters are not bidirectional:
| Adapter Type | Direction | Common Use Case |
| HDMI to DP Adapter | HDMI output → DisplayPort input | Xbox/PS5 to DP monitor |
| DP to HDMI Adapter | DisplayPort output → HDMI input | PC/laptop to TV or projector |
Attempting to use an HDMI to DP adapter in reverse will not work.
How to Choose the Right HDMI to DP Adapter
When shopping for an HDMI to DP adapter, keep these factors in mind:
- Resolution support: Make sure it supports up to 4K@60Hz if needed.
- USB power: Choose an adapter with USB power input for reliable performance.
- Build quality: Look for aluminum housing, braided cable, and gold-plated connectors.
- Plug-and-play: It should work without needing drivers or software.
- Audio support: Ensure the adapter transmits both video and digital audio.
