HDMI Only Laptop -- Dual Monitor Solution Requested

Daniel Van Der Werken
Daniel Van Der Werken used Ask the Experts™
HP ENVY Notebook PC
INTEL(R) HD Graphics 4600

Single HDMI output only.

Windows 8.1

The thing has four USB 3.0 ports -- one of them even charges.

I have one monitor connected to the single HDMI out port. How would I connect a second monitor such that it would work as standard Windows Dual Monitor.

I know I can split the HDMI out, but that would make both monitors show the identical images. I want to be able to use the second monitor showing different stuff.

I understand I need another graphics adapter. My only choice is a USB graphics adapter.

There are plenty of these things available, but I'd like some recommendations from folks here who have used them.

I don't have any HP Envy laptops (mine are HP EliteBook), but I'm pretty sure the Envy has a VGA connector in addition to HDMI. Simply connect a monitor via VGA and you'll be able to use both in an extended desktop config. That's what I'm doing with my HP EliteBook 2540p. Here's an article about it:

Update: Well, my bad! I just did some research on the Envy laptops and they don't have VGA ports...I'm guessing you knew that. :)

I have not used a USB video adapter, so I recommend that you wait to hear from folks with actual experience. That said, I have used many StarTech products with varying DisplayPort, HDMI, DVI, VGA, and USB features — they have all been excellent. I would not hesitate to try their USB video adapters. Here's a link at Amazon that shows several of StarTech's USB video adapters, including DVI, VGA, DisplayPort, HDMI, and even a dual monitor one (HDMI and DVI):

For best performance, get a USB 3.0 one (not USB 2.0) — I'm assuming your Envy has USB 3.0.

Sorry for the bad initial post. Regards, Joe
This is the one I have and love it, but it is expensive.
