A simple idea to have two screens ...

This is a very simple to use device that provides two simultaneous screens with the same machine.
One branch, the driver is installed, it will reboot and voila.
I plugged my laptop from on a screen 21 'nearby.
No particular difficulty.
I took to do some photo editing, which allowed me to have all the functionality on one screen and the other on the photo to retouch.
Frankly nothing wrong, the finish is good, damn good ergonomics is even equipped with a DVI / VGA adapter in the bundle.
As usual the manual (paper) is full English.
I do have not had utility for games, which in any case require a lot of system resources.

Would recommend for those who do not want to grind the brain in multiple facilities.
Here one branch and it works.
