Great portable triple monitor. The screens are sharp, lightweight, and easy to attach to my laptop Read more


I’m honestly obsessed with this screen extender. It looks super clean on my laptop and the quality is way better than I expected. The screens are clear, sturdy, and they attach perfectly without feeling heavy or cheap. It makes studying and working so much easier because I can have everything open at the same time without constantly switching tabs. Setup was quick, the cables aren’t annoying, and it just makes my whole desk look way more professional. For the price, it was totally worth it. Read more


This laptop extender works perfectly without any delay or lagging, and the quality of the screen is great! It was very easy to set up and use. Multitasking has become so much easier, and saves me so much time. Great for studying as well as working. The extender is very lightweight and easy to carry around, so I can use it anywhere. It is truly a great purchase for those who want to increase their efficiency! Read more
Just got today so this review is based on first impressions only at this point. (Will update the review if warranted). The Good: Very easy set up and very crisp, clear, sharp display. TBD: Color tones and resolution settings are different than my laptop. Color is blueish, and resolution larger. But hoping I can figure this out by playing with settings more. Also, per other reviews, it does seem cable-heavy, but I dont anticipate traveling w/it so that's not a big concern for me. The Bad: Stand is not stable. There's a magnetic side that attaches to the back of the monitor, and grooves to set the bottom of the monitor in. Very much like an iPad cover but, unfortunately, nowhere near as effective. The magnet is not that strong and the grooves very shallow. So, every time you basically touch the monitor the whole assembly/set up falls apart and you have to manipulate it back in place. This may seem trivial, but the entire purpose of it is having the convenience of a quick, easy 2nd monitor and having to wrestle w/setup every time seems like it may become tiresome. 9/18 Update: Just upgraded this review from 3* to 4*, based solely on the seller responding to my review above. She expressed apologies in a detailed reply, and then offered suggestions, potential solutions and assistance. It was so impressive a response it alone warranted this edit. (The stability is still a bit of an issue, but I've learned to work with it. ) I've never seen such a Read more
I use this for work when I travel for meetings. It works great and comes will all the necessary cables. Set up was super simple too, I had it going in less than 5 minutes. My laptop has the usb-c port so this portable monitor powers off my laptop for a few hours which is very handy, it is also very thin and lightweight. So far I’m very pleased with my purchase.

I got this as an external screen for my switch, which i love, but to be honest you it's no fun doing fitness boxing vs. a character that's 2 inches tall. the larger screen makes everything funner to use. that it's sturdy, easy to use, and i can pack it up makes it perfect for what i use it for.

As a teacher who’s constantly juggling lesson plans, grading, and meetings, the Laptop Screen Extender has been a lifesaver. Setup was unbelievably easy—one USB-C cable and it was ready to go. Having an extra screen for lesson materials, emails, and gradebooks has made my prep time so much more efficient. It’s lightweight, rotates smoothly, and fits perfectly in my teacher bag, which is a huge plus when I’m moving between classrooms. If you’re an educator looking for a simple, portable way to boost productivity, this monitor is absolutely worth it. Read more

I’ve been working with a single portable monitor for a while, and while it was an improvement over just the laptop screen, I constantly missed the efficiency of my multi-monitor setup at home. This KYY triple portable monitor is the perfect solution I've been searching for. My biggest concern with portable tech is always durability, and this device immediately put those fears to rest. The build quality is fantastic for the price—the panels use sturdy metal hinges, and the integrated kickstand is robust and holds the screens steady. It feels like it's actually designed to handle the rigors of travel. Setup was surprisingly simple. The package includes a small USB flash drive with all the necessary drivers for both Mac and Windows. I plugged it into my MacBook Air (M4), installed the driver, and was fully operational with all three screens in just a few minutes with the flexibility to set up my screens as if they were full size monitors (you can use 1 or 2 screens, the optionality is a nice feature). The best part is that it's all powered by a single USB-C cable from my laptop, meaning no extra power bricks or proprietary cables to pack. If you're looking to create a true multi-monitor workstation on the go, this is it. It's well-built, incredibly easy to use, and has completely transformed my productivity when I'm away from my desk. Highly recommend! Read more
