They say that people who use several screens are more productive. If you don't believe that, it is a fact that a bigger surface lets you see more. And that is how the Belgian Sliden'Joy was created, an additional screen (or two) that you can pull out from behind your screen, connect to a USB and you're ready to start working on a surface double or triple the size.

Sliden'Joy comes in three sizes – 13, 15 and 17 inches. The single additional screen will be available for purchase for 199 euro, the double for 299 euro, no matter the size.

The advantages of Sliden'Joy are that all you need for it to work is a USB 3.0 port, it has a high resolution (Full HD), can be turned 180 degrees, it's slim and light, which is a key factor when it comes to mobility and you can also personalize the back of the screen, but it will cost you a bit extra. Let us just add that it's Mac and PC compatible.

The project will go on Kickstarter in a few days and was already supported by the German electronics retailer Media Markt.
