This portable 14" secondary laptop display is perfect for anyone on the go looking to increase their screen surface area! As a office worker hopping between desks, I'm always struggling to get side-by-side views to fit on my tiny laptop screen. This product is simple, lightweight, and really easy to use to help me achieve my goals, and really improves my productivity. The product comes in a nice soft but durable travel / carry bag with handles, but it should be noted that the bag is open at the top. The screen connected immediately to my laptop via the USB-C connector, but there are other options for connectivity included as well. The screen is self powered by way of using the power from the connection to the driving device (in my case, a powered USB-C port on my laptop). It was recognized by Windows immediately, and did not require any detection or driver troubleshooting, it just came right up. From an attachment perspective, this thing is sturdy! It has a spring system that safely connects around the existing laptop screen, as well as a back-brace stand that helps support both screens with the added one contributing weight and making this necessary. I am very happy with this product, looking forward to using it for a long time!
EDIT 2024APR25: I loved the original single display so much, that I decided to buy the dual display also offered in this Amazon listing! I am just as happy with the dual display as I was with the single monitor. As someone who frequently visits customer locations, now I have two options available for screen surface area. The dual monitor display is just as easy to use. It attaches via compression to the back of my main monitor, and the included kick-stand effectively supports the product - even with additional weight. The USB-C connectivity booted right up, was recognized immediately by my Windows 11 laptop - and they look absolutely wonderful alongside my machine. Note that you will need two free USB-C connections to support the dual monitor, but the monitors themselves have extra ports built in so you actually gain ports. I have updated my pictures to include both the original single-display ones, as well as my new dual displays for reference. This is a great product and I love the ease, quality, and compact travel profile this product offers!

Kwumsy Laptop Screen Extender S2 Triple Laptop Screen Extender works wonders!!. It works so well, the setup is a breeze, no glitching, blinking, etc. The image quality is amazing. Nice to give extra screen to work on. Brilliant and has made my life easier. It takes me about 30 seconds to installed on my Laptop. It does have a handy case as well and it’s not much heavier than the laptop. As you can see the resolution is pretty good too. This is the best thing to happen to me at work from home! I can not express how amazing this device has been and how I can now be so efficient at work!!
I gave 5 stars because, this is such a great product! Boost my productivity significantly! No longer need to alt+tab and move your mouse everywhere on your laptop anymore... really really wish I could own this monitor extender earlier!!!
Love it.

Makes performing various tasks a lot more straightforward.
Reviewed in the United States on December 15, 2023
Transforming my small home office setup, this triple monitor extender has been a fantastic addition. As a programmer, juggling multiple tasks simultaneously is part of my daily routine. The ability to extend my laptop screen to three displays has remarkably increased my productivity. The differential display option is particularly useful, allowing me to run code on one screen, research on the second, and communicate with my team on the third. It’s incredibly user-friendly; just plug in and it’s ready to go. The slim design doesn’t clutter my workspace, and the lightweight build means I can easily move it to different rooms as needed. I am very satisfied with this product, great buy.
