The Best Laptop Screen Extenders for a Multi-Screen Setup
Five screen extenders compared on screen count, size, weight and laptop fit, plus the port checks that decide whether they work with your laptop.
By Alex Morgan, PC Hardware Editor
12 min read5 products evaluated
A laptop screen extender clips to or stands beside your laptop to add one or two screens, turning a laptop into a portable multi-monitor setup. Whether it works depends as much on your laptop's ports as on the extender.
We compared five extenders on screen count, size, weight and laptop fit, using their makers' listed specifications. We did not test them ourselves.
Before choosing a triple setup, check how many external displays your laptop supports. Many base-model MacBooks support only one.

Best Triple Extender1 of 5
Vixtan 14-Inch Triple Laptop Screen Extender
The Vixtan triple extender adds two 14-inch 1080p IPS screens around a 13 to 17.3-inch laptop while weighing 3 pounds.
Best for
- A portable three-screen setup.
Skip if
- Price-first buyers should look at the 14.2-inch ultra-portable, which cost less when we checked.
Why we like it
Height adjustment and 180-degree rotation let you tune the angles. On number of added screens it ties with the Rizpak 15.6-inch triple and the InnoView dual stacked at 2. On screen size it ties with the KEFEYA 14-inch at 14 in.
No other pick in this guide offers 13 to 17.3 in laptops; compare the Rizpak 15.6-inch triple, which has 12 to 17.3 in laptops. Like the Rizpak 15.6-inch triple, it has a 1080p IPS panel, while the InnoView dual stacked uses a 1920 x 1080 panel. It also offers a 0.3-inch thin body.
Before buying, check that your laptop's USB-C port outputs video (DisplayPort Alt Mode); otherwise you will need an HDMI port and a separate power cable. Its price falls between the KEFEYA 14-inch and the Rizpak 15.6-inch triple, based on our last check.

Best Large Triple Extender2 of 5
Rizpak 15.6-Inch Triple Laptop Screen Extender
The Rizpak triple extender uses two larger 15.6-inch 1080p IPS screens on a freestanding aluminum stand, so it does not hang off the laptop lid.
Best for
- Larger laptops and desk-based work.
Skip if
- Price-first buyers should look at the 14.2-inch ultra-portable, which cost less when we checked.
Why we like it
At 0.19 inches thin, it packs flat for a bag. On number of added screens it ties with the Vixtan 14-inch triple and the InnoView dual stacked at 2. No other pick in this guide offers 12 to 17.3 in laptops; compare the Vixtan 14-inch triple, which has 13 to 17.3 in laptops.
Like the Vixtan 14-inch triple, it has a 1080p IPS panel, while the InnoView dual stacked uses a 1920 x 1080 panel. You also get a 0.19-inch slim profile. Before buying, check that your laptop's USB-C port outputs video (DisplayPort Alt Mode); otherwise you will need an HDMI port and a separate power cable.
Driving two extra screens needs two video outputs or a laptop that supports multiple external displays over one port; many base-model MacBooks support only one external display. Its price falls between the Vixtan 14-inch triple and the InnoView dual stacked, based on our last check.

Most Portable3 of 5
14.2-Inch Ultra-Portable Laptop Screen Extender
This 14.2-inch extender is built for travel at 1.87 pounds, the lightest here.
Best for

Skip if

Why we like it
It adds one 1080p IPS screen rated at 300 nits with a 226-degree adjustable angle, for 14 to 17.3-inch laptops. On number of added screens it ties with the KEFEYA 14-inch at 1. On screen size it sits mid-pack at 14.2 in: the Rizpak 15.6-inch triple comes in at 15.6 in, and the KEFEYA 14-inch comes in at 14 in.
No other pick in this guide offers 14 to 17.3 in laptops; compare the Vixtan 14-inch triple, which has 13 to 17.3 in laptops. Before buying, check that your laptop's USB-C port outputs video (DisplayPort Alt Mode); otherwise you will need an HDMI port and a separate power cable.

Best Single-Screen Extender4 of 5
KEFEYA 14-Inch Laptop Screen Extender
The KEFEYA extender adds one 14-inch 1080p IPS screen that rotates 180 degrees, so you can turn it to face someone across a table.
Best for
- Adding one screen and showing it to someone across the table.
Skip if
- Pass on it if 60Hz office panel, not for fast games rules it out for your setup.
Why we like it
It works without drivers. It matches the 14.2-inch ultra-portable on number of added screens (1). It matches the Vixtan 14-inch triple on screen size (14 in).
It also comes with 180-degree rotation for sharing the screen and plug-and-play setup without drivers. Before buying, check that your laptop's USB-C port outputs video (DisplayPort Alt Mode); otherwise you will need an HDMI port and a separate power cable. It was priced above the 14.2-inch ultra-portable and below the Vixtan 14-inch triple at the time of writing. It gives ground on number of added screens, where the Vixtan 14-inch triple offers 2.
Key specs
- Added screens
- 1
- Screen size
- 14 in
- Panel
- 1080p IPS, 60Hz
Pros
- Adds one extra screen
- 14-inch screens
- 1080p IPS, 60Hz panel
- 180-degree rotation for sharing the screen
Cons
- 60Hz office panel, not for fast games
- Number of added screens trails the Vixtan 14-inch triple (2)
- Screen size trails the Rizpak 15.6-inch triple (15.6 in)
Best Stacked Dual Screen5 of 5
InnoView 15.6-Inch Dual Stacked Portable Monitor
The InnoView unit stacks two 15.6-inch screens vertically instead of beside the laptop, which suits narrow desks.
Best for
- Narrow desks and vertical workflows.
Skip if
- Skip it if price comes first: the 14.2-inch ultra-portable cost less when we checked.
Why we like it
The screens rotate from 0 to 315 degrees; InnoView asks for a power source of at least 30W. It matches the Vixtan 14-inch triple and the Rizpak 15.6-inch triple on number of added screens (2). A 1920 x 1080 panel is unique to it among these picks, while the Rizpak 15.6-inch triple uses a 1080p IPS panel.
It also offers 0 to 315-degree screen rotation and a foldable design. Before buying, check that your laptop's USB-C port outputs video (DisplayPort Alt Mode); otherwise you will need an HDMI port and a separate power cable. Driving two extra screens needs two video outputs or a laptop that supports multiple external displays over one port; many base-model MacBooks support only one external display.
A stacked design adds screens above rather than beside the laptop, which saves desk width. At our last price check it topped the group, with the Rizpak 15.6-inch triple the nearest cheaper option.

- Added screens
- 2
- Screen size
