I bought a few of these but didn't need them all so I'm selling the extra ones. I used them to add extra monitors to my laptops. Gave me the ability to add a 3rd and 4th monitor (4th monitor mirrors the 3rd) on my Win 10 and Win 11 laptops.

Plug it into USB port. A flash drive appears with folders for Windows and Mac drivers. Open the folder you need, double-click the driver. When the installation is complete, reboot and plug in your monitor. (If using one monitor and it isn't detected, switch to the other HDMI port on the adapter - I learned that the "hard" way - grin.)

If you've got an older system (desktop or laptop) without an extra HDMI output, this is a great way to add a second monitor. If your system already supports two monitors, this is a awesome way to add a third monitor without buying and installing another video card.

This sale is for one unit at the marked price. Discounted, combined shipping if you buy both.

Package comes with the adapter and an integrated USB 2.0/3.0 cable. Nothing else is included.

Thanks for looking.
