Hi @Dan827 

Welcome to the HP Support Community! We're here to help you get back up and running.

I understand how limiting it feels when your HP 14‑em0015na’s USB‑C port doesn’t support DisplayPort, and you’re trying to extend your display cost‑effectively. 

You’ve already identified the limitation, so let’s go through practical ways to add HDMI output without relying on USB‑C video passthrough.

 

Check existing ports

• Your model includes HDMI output. If you only need one external monitor, connect directly via HDMI cable.
• If you want a second external display, you’ll need an adapter solution.

Use a USB Display Adapter (USB‑A to HDMI)

• Since the USB‑C port doesn’t carry video, you can use a USB 3.0 (USB‑A) to HDMI adapter.
• These adapters use DisplayLink technology to provide video output through USB.
• They are cost‑effective and widely available, supporting resolutions up to 1080p or 4K depending on the model.

Docking stations with DisplayLink

• A compact USB docking station connected via USB‑A can provide multiple video outputs (HDMI, DisplayPort).
• This is useful if you want dual monitors or additional ports like Ethernet and USB expansion.

Avoid passive USB‑C to HDMI cables

• Passive cables only work if the USB‑C port supports DisplayPort Alt Mode, which your laptop does not.
• Stick to active adapters or docks that use DisplayLink drivers.

Driver installation

• For DisplayLink adapters, download and install the latest Windows 10 drivers from the manufacturer’s site.
• After installation, connect the adapter, plug in the HDMI cable, and extend the display via Windows Display Settings.

By using a USB 3.0 to HDMI adapter or a DisplayLink docking station, you can extend your monitor display without relying on USB‑C video passthrough.
