Cannot connect Monitor with USB C port on my device

[PP1119]

Hi,

Can anyone suggest work-around to connect monitor with USB-C port (may be I need an adaptor to connect with monitor and  in-built USB C-port). Looks like existing USB Type C port  not compatible for display

(PS: with HDMI Monitor connection it produces intermittent connect/disconnect Beep sound )

Appreciate any suggestion

@PP1119, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
It sounds like you're dealing with a display issue on your HP 15.6 inch Laptop PC 15. Based on your description, here’s what you need to know about the USB-C port and some effective workarounds to resolve the issue.

🧠 Key Insight: USB-C Port Type

The USB-C port on your model does not support video output (DisplayPort over USB-C). It is only for data transfer and charging, which is why connecting a USB-C to HDMI or USB-C to DisplayPort cable doesn’t work. So, you are correct—the USB-C port on your laptop is not compatible for display output.

✅ Workaround Suggestions

1. Use the HDMI Port

If you're experiencing intermittent beeping with the HDMI connection, it could be due to a cable, driver, or port issue. Here are some steps to troubleshoot:

• Try a Different HDMI Cable: Some cables can be faulty or not fit securely.
• Test with a Different Monitor: If possible, try connecting to a different monitor or use a different HDMI port on the same monitor.
• Update Display Drivers: Go to Device Manager and check for updates for your display drivers, or use the HP Support Assistant to ensure you have the latest drivers.
• Use a Powered HDMI Splitter or Signal Booster: If the HDMI port seems weak, a powered splitter or signal booster can help stabilize the connection.

2. Use a USB Display Adapter (External Video Card)

Since the USB-C port won’t work for display, consider using a USB-A port with a USB to HDMI adapter:

• Look for a USB to HDMI adapter that uses DisplayLink technology. A good option is the Plugable USB 3.0 to HDMI Adapter, which can support 1080p or even 4K displays.

🔧 Additional Tip for HDMI Beep Issue

If the HDMI monitor causes connect/disconnect beep sounds:

• Open Device Manager and navigate to Sound, video and game controllers. Disable “HDMI Audio” under your GPU.
• Alternatively, go to Control Panel > Sound > Playback Devices, set your speakers as the default device, and disable the monitor output.

I hope this helps. 

Take care and have a good day.
