S3 dual monitors for laptops

[pmont5100]

I have a HP Laptop (2022).  It has 1 HDMI port, 2 USB ports, and one USB-C Port.  I have an HP Hub.  I am trying to hook up the S3 dual monitors for laptops.  I can get one screen to work, but not the other.  How can I get both screens to work?

Hi @pmont5100 

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

Thanks for describing the setup—you’re so close to a great dual-monitor experience, and I’m here to help tie it all together! 😊 Let’s figure out whether your laptop’s USB-C port supports dual video output, as that’s the key to getting both screens lit up.

Could you share the following details to help narrow down compatibility?

📋 Info That Will Help Me Check Compatibility

• Exact model name or number of your laptop (e.g., “HP 15s-eqxxxx” or “HP Pavilion 15-egxxxxx”). You’ll often find this on a label on the bottom of the laptop or in System Information (Win + Pause/Break > look for “System SKU”).
• Full name or model of the HP Hub you’re using—some support dual monitors through DisplayLink, while others rely on pass-through.
• How the monitors are connected:
  • Are both using HDMI?
  • Are either connected via DisplayPort, USB-C, or a mix?
• Which ports are being used on the laptop currently (HDMI directly, USB-C via hub, etc.)
• Is the USB-C port marked with a thunderbolt icon (⚡) or labeled as supporting DisplayPort?

Once I have that info, I’ll check if your laptop’s USB-C port supports multiple external displays, and guide you step by step to make the dual-screen setup work flawlessly. Let’s crack this together and make it shine! 💻🖥️🖥️

Note: Do not share any of your personal information in public, such as serial number, phone number, email ID, etc.

Take care, and have an amazing day!

The hub is an HP Universal USB-C Multiport Hub

I have tried both ways.  Hooking up via HDMI, one using the HDMI on the laptop, and one using the HDMI on the Hub, and I have tried the USB-C, and cannot get them both to work.  The USB C is labeled with a thunderbolt on the computer, as well as on the hub. I can get the monitor to work that is plugged into to the HDMI on the laptop, but not the USB-C.  Although the mouse, CAC Reader all work using the hub, the monitors will not work using the hub.

Your help is most gratefully appreciated!
