HP Pavilion 21 Desktop Compatibility

I have recently purchased the HP Pavilion 21 desk top touch screen computer running Windows 8.1 and did not notice at the time that there were no HDMI ports. I need to connect my second monitor which I use extensively for my home engraving based business. I am considering buying the Plugable UD-3900 Dual Display Universal Docking Station and want to know if is the fix I am looking for. As I am not sure I will ever find this thread again so could you also send the reply to my email trails@epix.net. Thanks so much for all your help.

Hi there,

Thank you for posting the question at Plugable Get Satisfaction. I’d be happy to assist.

Yes, UD-3900 had two graphics ports (one DVI and one HDMI) so that you can connect up to 2 external monitors to your system. It also has total 6 USB ports, the Gigabit Ethernet port and audio input/output.

If you only wanted to connect a HDMI monitor, the UD-3900 would be too much, though. Plugable also has a different types of USB graphics adapters that supports HDMI:

-Plugable USB3-HDMI-DVI USB 3.0 to HDMI/DVI Adapter

If you want to use audio over the HDMI monitor, please choose the USB3-HDMI-DVI adapter. UGA-3000 doesn’t support audio when connecting through HDMI.

Hope this helps! Please let us know at support@plugable.com if you needed any additional information.
