can a laptop dock, with the laptop closed, to two screens, keyboard and a mouse at the same time

Want to connect two screens, keyboard, mouse and network to one Laptop, and have the Laptop closed, can this be done?

Hi Jerry,

Thank you for posting the question here.

Our UD-3900 docking station would allow you to connect two external monitors and other peripherals to your Windows PC via single USB 3.0 cable.

It depends on the PC settings if you could close the laptop when connecting those external devices or not, though.

Some of them could be going to sleep mode when in the clam-shell mode. But most of the cases you should be able to change the behavior by using the proprietary software or changing the BIOS settings.

We have experienced that a few laptop models went very slow when it’s closed, and there wasn’t any way to change it. Please note that, in that case, the solution need to be provided by the laptop manufacture as the system/BIOS update for the particular laptops.

Hope this helps! If you have any other questions or concerns, please directly contact us at so that we could help.
