Dual Displays

I have an HP Envy laptop and i just bought 2 - 32" TVs to use as monitors. What would be the best way to connect the 2 displays to my computer? I tried using an HDMI cable (which works correctly on one of the TVs) and i bought a USB Type C - to HDMI adapter to connect the other tv, but my computer will not find the 2nd TV. I was looking at the PLUGABLE UD-3900 DUAL DISPLAY UNIVERSAL DOCKING STATION, would this be a good choice or is there something a little cheaper i could use?

Thanks, any help would be appreciated.


Thanks for reaching out to us, I am happy to help!

I would like to start off by getting some additional information about your computer and televisions to help make sure we find a good solution. When you have a chance, please let me know the model number of the HP Envy ( normally on the bottom of the notebook ) as well as the manufacturer names and model numbers of the televisions. I will use the model numbers to verify the connection options and find a solution that will meet your needs.

Thank you,


Hi Pat,

My laptop model number is: HP ENVY - 15t-as100 CTO.
The tvs are Insignia 32" LED, model number: NS-32D220NA18.


Thanks for the additional information!

I checked HP’s product page for this system and it does not specifically state support for USB-C Video output which likely means this is not enabled on this system ( USB-C DisplayPort Alternate Mode is the current standard for outputting video over USB-C and Thunderbolt 3, this is an optional feature that has to be specifically enabled by the system manufacturer ).

This system should work well with our UD-3900 USB 3.0 Dual Display Docking Station ( https://plugable.com/products/ud-3900 ). Alternatively our USB3-3900DHE USB 3.0 Dual Display Adapter for Multiple Monitors with Gigabit Ethernet ( https://plugable.com/products/usb3-3900dhe ) does not provide the additional USB ports, nor does it require an external power supply. This adapter will drive both displays, one can be connected directly to the adapter’s HDMI output while the other will need a DVI-to-HDMI adapter or cable ( available from Amazon or other retailers ).

Both the docking station and graphics adapter require the DisplayLink software to be installed on the system, available from our website here ( https://plugable.com/drivers/displaylink ). We recommend DisplayLink based USB graphics adapters and docking stations for use with office and web browsing software, displays on the DisplayLink device may not be well suited for full screen video playback, 2D or 3D graphics software, video editing software, or some stock trading applications. We do not support gaming on DisplayLink attached displays.

Please let me know if this helps, or if you have any additional questions.
