Yes, DisplayPort to HDMI works — you just need the right type of adapter for your setup.
- Your GPU supports DP++ (passive adapter, up to 1080p)
- You use an active adapter for 4K@60Hz or non-DP++ sources
- Your DisplayPort and HDMI versions are matched (e.g., DP 1.4+ for 4K)
- You use a passive adapter on a non-DP++ source
- You try to run HDMI-to-DisplayPort in reverse with a standard adapter
- Your adapter is older and lacks audio pass-through or limits refresh rates
Passive vs. Active Adapters
The biggest decision when connecting DisplayPort to HDMI is whether you need a passive or active adapter.
A passive adapter works when your graphics card or source device supports DP++ (Dual Mode DisplayPort). This mode lets the port output an HDMI-compatible signal directly, making it plug-and-play with no quality loss. Passive adapters are inexpensive and handle resolutions up to 1080p without issue.
An active adapter includes a built-in signal conversion chip. It works with non-DP++ sources, supports higher resolutions like 4K@60Hz, and is required for multi-monitor setups or when connecting via USB-C Alternate Mode. If you are unsure which type you need, an active adapter is the safer choice.
For a detailed breakdown of the passive vs. active question, see Barco’s guide on DisplayPort to HDMI conversion.
Common Setups at a Glance
| Setup | Works? | Need | Note |
|---|---|---|---|
| GPU (DP++) → HDMI monitor, 1080p | Yes | Passive adapter | Plug-and-play |
| GPU → HDMI monitor, 4K@60Hz | Yes | Active adapter + DP 1.4 | Check HDMI version too |
| USB-C (Alt Mode) → HDMI monitor | Yes | Active adapter | No DP++ on USB-C |
| HDMI source → DisplayPort monitor | No | Different adapter needed | Direction matters |
Direction Matters
DisplayPort to HDMI is a one-way conversion. A standard DP-to-HDMI adapter cannot be reversed to send an HDMI signal into a DisplayPort display. If you need to go the other direction, you need an adapter specifically designed for HDMI-to-DisplayPort, which requires its own active chip.
Audio and Refresh Rate Notes
Most DisplayPort to HDMI adapters pass audio through without any extra configuration. However, older or cheaper adapters may strip audio entirely or cap refresh rates at 60Hz. If you are targeting 120Hz or higher on an HDMI display, confirm the adapter and cable both support the required bandwidth.
If you are connecting via a USB-C port, check out whether USB-C can connect to HDMI for a full breakdown of what your port supports. Also see whether your USB-C port supports video output before buying an adapter.
Quick Checklist
- Confirm your source supports DP++ if using a passive adapter
- Use an active adapter for 4K, USB-C, or non-standard sources
- Match DP and HDMI versions for the resolution you want
- Check adapter specs for audio support and max refresh rate
Bottom line: DisplayPort to HDMI works reliably when you match the adapter type to your source. A passive adapter handles most everyday setups at 1080p, while an active adapter covers 4K, USB-C Alt Mode, and anything outside standard DP++ support.
