Double Screen Laptops or Screen Extenders?

There’s no getting around owning a laptop these days, especially if we travel often or don’t have the space for a desktop computer. And more and more scenarios for using multiple screens.

It is great for meetings, nothing screams “I am a tech person” like “let me show that in the multi screen”. Great to garner attention at trade shows too, if you don’t have any flashy machine to show.

Well-known computer brands ASUS and Lenovo have launched dual-screen laptops

The Zenbook Duo looks like a regular laptop until you remove the keyboard and trackpad that cover the entire bottom screen.

The Yoga Book, meanwhile, looks like two tablets stuck together, and its keyboard hides only half of the bottom screen, so you know right away that it’s different.

Both the Zenbook Duo and Yoga Book 9i can be used as traditional laptops with either a physical keyboard and trackpad (Zenbook) or a physical keyboard and mouse (Yoga Book); taking notes on the bottom display in clamshell mode; or with their displays oriented vertically or horizontally. They both also have virtual keyboards and trackpads.

For the dual screens to remain stable while upright, the Zenbook Duo has a kickstand attached to the bottom chassis, while the Yoga Book comes with a keyboard folio cover that transforms into a stand with a flat, triangular back and a thick lip at the bottom to keep the laptop in place.

Neither of these laptops is great for using directly on your lap, though. The Zenbook Duo can get uncomfortably hot if the processor is running as fast as it can, and there’s a vent that blows hot air directly into your lap. The Yoga Book is fine temperature-wise, but the keyboard can easily shift and twist a few centimeters despite attaching magnetically over the bottom display.

Laptop screen extenders are becoming popular. For example, the Bosii brand has dual-screen and triple-screen products to adapt to various laptop models, and also provides accessories to connect different laptop models.


The lightness and flexibility of this type of product have made it increasingly popular. It can be found on major e-commerce shopping platforms. The screen can be rotated and disassembled and assembled flexibly, and can be used in different scenarios.Y
ou’re able to bring those add-on monitors along to your next laptop upgrades, rather than buying them again.

To sum up, you can choose the multi-screen portable solution that suits you best according to your needs.
