I have two monitors in my office. When I need to review an order with my sales team or there is an issue with ERP accounting, I usually rotate one of the monitors so multiple people can share the screen with me. Other times I might need to discuss something with 5 or 6 other people and going to the conference room to use the projector would be too much. In these cases, I use this device to expand my setup to three monitors by sharing the main screen with an additional monitor that I mount on my wall. Please note that this product is not "extended" or "spread" across multiple monitors to use Windows terminology. What it does is duplicate a screen onto another screen. Don't buy this if you're looking for a way to expand or extend your desktop.
