KOJOM 2K Triple-Screen Laptop Extender - Turn One Laptop Into a Three-Screen Workspace
Two 13" 2K IPS displays expand your laptop workspace for multitasking, meetings, analysis, entertainment, and mobile work
The KOJOM Laptop Screen Extender adds two 13-inch 2K IPS displays to a compatible laptop, creating a three-screen workstation without requiring a permanent multi-monitor desk.
Each extended display features 2160 × 1440 resolution, 330-nit brightness, and a 1000:1 contrast ratio, giving you additional screen space with detailed visuals for work, video calls, content viewing, and other compatible tasks.
Keep three work areas visible at the same time
Instead of constantly switching between windows, the KOJOM extender lets you spread information across your laptop screen and two additional displays.
That makes it easier to keep separate tasks visible while you work.
✓ Triple-screen workspace — your laptop display plus two extended monitors.
✓ Multiple windows at once — useful for multitasking, remote work, video conferencing, and entertainment.
✓ Expansion, mirroring, and second-screen modes — choose how each display fits your workflow.
✓ 180° screen rotation — adjust the side monitors according to your preferred viewing position.
2K resolution brings more detail to both extended screens
Each 13-inch monitor features a 2160 × 1440 2K IPS display.
The combination of high resolution, 330-nit brightness, and a 1000:1 contrast ratio is designed to deliver detailed images with clear and bright color reproduction.
2160 × 1440 resolution → more visual detail across the extended workspace.
IPS display → the stated panel technology for both side screens.
330 nits → the specified brightness level.
1000:1 contrast ratio → the stated contrast specification.
The extender also includes a built-in speaker, adding integrated audio capability to the setup.
Built for workflows that need more than one screen
The triple-screen format can support several types of work without forcing everything onto one display.
For remote workKeep a video conference visible while working on another screen.
For programmingSeparate code, references, or supporting information across multiple displays.
For stock monitoringKeep more charts, data, or information visible simultaneously.
For entertainmentUse the additional screens for supported video or gaming setups.
The benefit is simple: more visible workspace without repeatedly rearranging windows on a single laptop display.
Plug-and-play connectivity with compatible laptops
The KOJOM extender is designed for 13"–17" laptops and supports Windows, Mac, Chrome, and Nintendo Switch as stated.
Connection depends on the ports available on your computer.
With two full-featured USB-C portsThe two extended screens can connect using two cables.
With one full-featured USB-C portThe other screen can use HDMI together with a USB-A to USB-C cable for power.
When HDMI is used, the product description specifies that an additional USB-A to USB-C power connection is required for that screen.
The laptop must have at least one full-featured USB-C port for the stated setup.
Adjust the screens to your viewing position
Both extended monitors support up to 180° rotation, allowing you to change their angle rather than working with a fixed side-screen position.
The product also supports:
Expansion mode
Mirroring mode
Second-screen mode
Brightness adjustment
Sound adjustment
Contrast adjustment
The controls are described as accessible through a button positioned on the top of the unit.
Portable enough to move beyond a permanent desk
The complete extender is listed at 3.3 lb and is designed to slide into a bag for transportation.
That makes the triple-screen setup suitable for moving between locations such as:
Home
Office
Coffee shop
Hotel
Airport
Other temporary workspaces
Instead of rebuilding a traditional multi-monitor setup at every location, you can carry the additional screens with your laptop.
Check Mac compatibility before choosing
The product description specifically states compatibility with:
MacBook Air 2018–2019 models
It also lists support for Macs using:
M1 Pro / MaxM2 Pro / MaxM3 Pro / Max
However, it states that the extender is not directly compatible with standard M1, M2, or M3 chips unless used with the KOJOM H4 hub, which is not included.
Checking your laptop model and available ports before purchase is essential for confirming the correct connection setup.
