KEFEYA Laptop Screen Extender, 14" FHD 1080P IPS Laptop Monitor Extender Dual Screen, Portable Monitor for Laptops 13-17" with USB-C/HDMI Port, Plug n Play for Windows/Mac/Android/Switch/PS5

Very happy with this purchase. The screen is clear and sharp and the size works perfectly with my laptop. Setup was super easy, just plug and play. I’ve used it with USB C and HDMI, and both worked without any issues. Makes multitasking much easier, especially when working or travelling. Honestly, I bought another two-screen setup before, and it was very heavy and complicated to set up. It looked fancy but wasn’t practical. This one is simple, easy to use, quick to get up and running, compact, and easy to travel with. You only need one cable, which makes a big difference. great value for money, so far no issues with it but If I find something I'll update it here

I recently purchased the KEFEYA S1 Dual Screen Laptop Extender, and I can honestly say it exceeded my expectations. The setup was incredibly simple — just plug and play, and it worked perfectly with my laptop without any complicated installation. The screen quality is sharp and vibrant, making multitasking so much easier. As someone who works on multiple projects at once, having extra screen space has significantly boosted my productivity. I can now manage emails on one screen, work on documents on another, and keep meetings open without constantly switching tabs. The build quality feels solid and durable, yet it’s lightweight enough to carry when traveling. It folds neatly and fits well in my laptop bag, which makes it perfect for remote work or business trips. If you’re looking to upgrade your workflow and work more efficiently, I highly recommend the KEFEYA S1. It’s a smart investment for anyone serious about productivity!

I’m really impressed with this portable triple monitor for my laptop. The detachable design is super convenient, and it even comes with a nice leather bag so I can easily pack it and take it anywhere. It’s perfect for working from home or setting up a workstation while traveling. The screen extender makes multitasking so much easier. I can have multiple windows open at the same time for work, video calls, or even watching something on the side without constantly switching tabs. It definitely helps me stay more productive throughout the day.

Since I started using this 15.6” portable screen extender, my workflow has improved a lot. The image looks clear, the colors are vibrant, and it allows me to keep multiple windows open without constantly switching between tabs. Setup was simple, and the adjustable rotation makes it easy to position it comfortably. It’s practical, portable, and a great solution if you want more screen space while working from your laptop.

First, out of the box, it's a very easy setup IF you have a fully powered USB-C port on your laptop. Most newer ones do but be sure you have such a port (usually indicated by a small lightening symbol by it); if you don't, even though they send you USB-C to USB-A and USB-C to HDMI cables, they will NOT power the monitor enough. I imagine you'd have to buy the separate power adapter for the monitor they mention in the ad (NOT included) to make such a setup work. So be aware of that. I suppose perhaps they don't work just on my particular laptop, but I doubt that's the case. With the supplied USB-C to USB-C cable it works perfectly. Well, I won't say "perfectly" (and this is the reason I gave only 4 over all stars) because as you can see from the first picture, when compared to my native monitor, the colors are different. It doesn't matter what setting I use or adjust on the S1 monitor. I can never get it to be like the native monitor of my laptop (ROG STRIX). I suspect the reason for this is because one cannot utilize "HDR" on this monitor. Note the picture of the HDR setting. It's off by default and for good reason; if you turn it on, the screen goes dark and will not return until you turn HDR off. I suspect it can't be turned on because, maybe, you'd need the power adapter they mention to enable that feature. (the power from just the USB-C port, even a full powered one isn't enough). This is my suspicion but I can't confirm it as I don't have the power adapter they mention (I don't even know what it is to be honest, as it's rather vague their description of the "power adapter"). Regardless, HDR will not function on this monitor with just the equipment they provide. Now, with that said, it's a *perfectly fine* monitor for what I wanted, which was just a second monitor to turn my laptop into a mini-desktop setup. So I could play games on my laptop (in full screen) while sitting in my favorite chair and still have the ability to check email (or other websites) on the other screen. It's perfect for this, and really will be perfect for many situations that don't entail gaming. As you can see from the refresh rate tests attached, the refresh rate is approximately 50Hz (even though it says "calculating" the test never got to a state where it would be "finished" as in the test for my native monitor at 240Hz). But the test is accurate as it accurately reports the refresh rate for my native monitor. So, I'm quite confident it's accurate when testing this monitor. I can't tell you what website I went to test it, as my first review was rejected, I THINK because the screenshots had the testing website URL in it. So, I edited that out. Hopefully THIS review goes through. But you can search for any refresh test online it's quite easy and straightforward. The point is, that this is NOT a gaming monitor by any stretch of the imagination, but it's perfectly fine for non-gaming applications. The first picture of the entire setup is NOT edited in any way, that's how the color difference is. At first it was a little annoying (disappointing really) but I got used to it and really don't notice the difference anymore, but it is there in an objective sense. The colors don't seem as "rich" (i.e., they're washed out) on the S1 monitor compared to my laptop's own monitor. Again, not sure why but I suspect it's the HDR issue above. But again, really doesn't matter for doing stuff that's not gaming. As you can see, I don't use the kickstand that comes with it (on the back of the monitor). I'm not sure why it was built into the design it doesn't seem necessary. I was a bit concerned that the hinge may become worn and eventually not support the weight of the monitor but as I write this now it's well over a month since I've had this monitor and still the hinge/support system (without the kickstand) supports its weight perfectly fine without showing any signs of wear on the hinge. So again, not sure what the kickstand is for. I wouldn't worry about the weight of it in other words, it's more a question of whether or not you are expecting a decent refresh rate for gaming and/or if you don't have a USB-C connection. Don't buy this for gaming; don't buy it if you don't have a USB-C port. DO buy it though if you just want a mini-desktop (like me) and don't care too much about the (somewhat slight) color differences. You actually might not have a difference if you don't have a gaming laptop actually. As a side note, the weight of it is not too heavy to be supported by lighter laptops like an HP Elitebook, which I also have for work. Again, you don't need the kickstand even for a light laptop like that. It holds up fine on its own. I hope you found this review useful. Edit: A few days after posting this review, the seller reached out to me to try some color adjustments on the monitor, to see if that would work to get the S1 to be the same as my own laptop's monitor. While sadly they didn't work, it did make the difference less noticeable, (not pictured). For this reason (since they reached out to me) I'm revising my review to five stars. It was good customer service I'd say.

This screen extender has completely transformed my workflow. It's incredibly easy to set up—literally plug and play. The extra screen real estate is perfect for monitoring multiple windows or charts at once without being tied to a desk. It’s lightweight, fits perfectly in my bag, and the display quality is surprisingly crisp. If you need to stay productive while on the move, this is a must-have. Highly recommended!

This product is great. Fairly easy to set up. I had trouble with display and contacted support and they walked me through a little wheel adjustment on this screen that greatly improved the display. I didn’t even see the wheel at first. However, why is the kickstand on the laptop side, not on the monitor side? I find that the weight or perhaps just gravity will occasionally cause the screen to fall off the laptop connection. I have a book propped under this monitor now which by ridiculous. The kickstand on the monitor side would fix this. I cannot find any device to use to prop this up and keep it fully sturdy. An adjustable kickstand on the monitor would totally fix this! Why is the kickstand on the monitor side anyway?

This portable triple monitor is a very useful product for work and travel. The screens are clear, bright, and easy to use, and the 1080P display looks great for meetings, movies, and daily tasks. I like that it supports different modes and rotates, so I can set it up the way I want. It is plug and play, which saves time and makes setup simple. The detachable design is also convenient. The packaging is great, and the carry on case is great too, making it easy to protect and carry anywhere. Overall, it helps me work faster and better.
