HDMI to DisplayPort Cable Guide: Direction, USB Power, 4K60 & Compatibility

If your source device has an HDMI output but your monitor has a DisplayPort input, you need an active HDMI-to-DisplayPort converter rather than a simple passive cable. The MOSHOU HDMI-to-DP cable is directional, uses USB-A auxiliary power for its conversion circuitry, and is designed for up to 4K60 output with compatible devices.

Quick answer: which direction does HDMI to DisplayPort work?

This cable converts HDMI source → DisplayPort display. Connect the HDMI male plug to a PC, laptop, game console or media device with HDMI output, and connect the DisplayPort male plug to a monitor with DP input. It does not work in reverse for a DisplayPort source and HDMI display.

Why HDMI-to-DisplayPort conversion needs active electronics

HDMI and DisplayPort use different signaling systems. An active converter contains electronics that translate the incoming HDMI signal into a DisplayPort-compatible output. That is why HDMI-to-DP products should not be treated like ordinary passive cables.

The integrated USB-A lead supplies power to the converter circuitry. It does not charge the monitor or increase the computer's video performance.

What does 4K60 compatibility depend on?

The cable is specified for up to 4K at 60Hz and also supports common lower-resolution modes, including up to 2K at 120Hz. Actual output depends on the complete signal chain: the HDMI source port, the monitor's DisplayPort input, graphics hardware, operating-system settings and the selected resolution and refresh rate.

If a system does not display at the highest mode immediately, first verify that both source and monitor support the requested resolution and refresh rate, then try a lower mode before troubleshooting the cable itself.

Correct connection sequence

1. Connect the HDMI plug to the source device's HDMI output.
2. Connect the DisplayPort plug to the monitor's DP input.
3. Connect the USB-A power lead to a powered USB port or suitable 5V USB power source.
4. Select the correct DisplayPort input on the monitor.
5. Set a resolution and refresh rate supported by the complete setup.

HDMI to DP vs DP to HDMI

For a broader connector comparison, see our HDMI vs DisplayPort guide. If you are comparing high-resolution modes, our video bandwidth guide explains why resolution and refresh rate must be evaluated together.

Does it carry audio?

Yes, the product is designed to carry synchronized digital video and audio to a compatible DisplayPort display. Audio output still depends on the source settings and whether the connected monitor supports audio playback or audio pass-through.

Common no-signal checks

• Confirm the HDMI end is connected to the source and the DP end to the display.
• Make sure the USB-A power lead is connected to a powered port.
• Select the correct DisplayPort input on the monitor.
• Test at 1080p or a lower refresh rate first.
• Reconnect the cable after the source and monitor are fully powered.
• Check whether the source device actually outputs video through the selected HDMI port.

Before You Buy

• This product is one-way: HDMI source to DisplayPort display only.
• USB auxiliary power is required during use.
• Maximum resolution and refresh rate depend on the full hardware chain.
• It is not a splitter, multi-monitor hub or passive adapter.
• Choose 1m, 1.5m, 2m or 3m based on your desk layout and cable-routing needs.

FAQ

1. Can I use this from DisplayPort to HDMI?

No. It is designed only for HDMI source to DisplayPort display conversion.

2. Why is there a USB-A plug?

The USB-A connection powers the active signal-conversion electronics inside the cable.

3. Does USB power charge my monitor?

No. It powers the converter circuitry only.

4. Can it output 4K at 60Hz?

The product is specified for up to 4K60 with compatible source and display hardware.

5. Can it support 120Hz?

The current listing specifies up to 2K120. Actual available modes depend on the source, monitor and settings.

6. Does it carry sound?

Yes, it is designed for digital audio and video transmission to a compatible DP display.

7. Can I connect a game console to a DisplayPort monitor?

Yes, when the console has HDMI output and the monitor has a compatible DisplayPort input. Use the USB power lead as required.

8. Why do I get no signal?

Check direction, USB power, monitor input selection and resolution/refresh settings first.

9. Is this the same as an HDMI cable with a different plug?

No. It is an active converter cable with signal-processing electronics.

Final verdict

Choose an active HDMI-to-DisplayPort cable when your source only offers HDMI and your display requires DisplayPort. The most important buying checks are direction, USB power and the resolution/refresh-rate capability of the complete setup.
