Cevaton Triple Screen Extender Review: Can It Really Turn Your Laptop Into a 3-Screen Setup?

Why I Tried the Cevaton Triple Screen Extender?

I’m someone who works across tabs all day—documents, emails, and sometimes spreadsheets. Switching between windows slows me down. 

That’s why I decided to test out the Cevaton 15.6″ Laptop Triple Screen Extender. 

It promises to add two extra screens to your laptop, giving you a full three-screen experience without the need for a docking station.

But before getting excited, I wanted to see how well it really works in day-to-day use.

My Setup Experience (and What You Should Know)

The box came with two 15.6-inch screens, a metal folding frame, and all kinds of cables—USB-C to USB-C, HDMI, and USB-A adapters. It’s supposed to work without needing a separate power source, but that depends on your laptop.

Setting it up wasn’t as plug-and-play as I hoped. I had to try different cables to get both monitors working. On one of my older laptops, only one screen was connected. Turns out, not every USB-C or HDMI port supports video output.

So before buying, I recommend checking if your laptop ports support full video and power delivery. Cevaton has a compatibility list on their website.

Display Quality and Viewing Angles

Once I got the screens running, I was actually impressed. Both monitors deliver 1080p full HD resolution with 120% sRGB color and 300 nits brightness. 

I could view the screens clearly even under indoor lighting. The extenders rotate 235° horizontally and 90° vertically, letting me position them however I needed.

From portrait mode for reading to landscape split-view for multitasking, it really gave me the flexibility I’d hoped for.

This flexibility helped when I moved into meetings or shifted between home and coworking setups.

Real-World Use: What Worked and What Didn't

The frame felt strong but added weight—each monitor is around 2.1 pounds, so this isn’t super lightweight. Still, it fit in the included travel bag. I used it on my 15" laptop, and the adjustable frame handled it well.

One downside? The power/brightness button is tiny and sensitive. Once I thought a screen was dead, but I had just set the brightness too low. Holding the button for 5 seconds fixed it.

It worked great when I was settled at a desk, but it’s not ideal for quick, on-the-go setups.

Device Compatibility (Read This Before You Buy)

Cevaton says the extender works with:

• Windows and ChromeOS laptops
• MacBooks with M1 Pro, M2 Pro, or M3 Pro chips
• Android devices with video output
• Nintendo Switch, PS4, Xbox

But here’s the catch—it doesn’t support base M1/M2/M3 MacBooks. 

I tested this myself, and only my M1 Pro MacBook worked. Also, not all USB-C ports on laptops support video. If yours doesn’t, you’ll need to use HDMI and power the monitor separately.

So definitely double-check this compatibility page before ordering.

Is It Worth the Price?

When I first saw the $500 price tag, I was hesitant. But now it’s selling for $299 on Amazon, and at that price, I think it delivers value—if your laptop supports it. I didn’t need a docking station or external power hub. It simplified my setup a lot once it was running.

But if you're someone who moves between laptops or uses entry-level machines, setup could be tricky.

Final Thoughts: Should You Get the Cevaton Extender?

For me, the Cevaton Triple Screen Extender added real productivity gains. I stopped jumping between tabs and could work faster across three screens. But it’s not perfect—setup takes patience, and compatibility depends on your device.

If you're a content creator, coder, or remote worker and your laptop has the right ports, this could be a smart investment.

Just check your ports and compatibility first. If that checks out, this extender can truly turn your laptop into a powerful multitasking machine.
