Kwumsy Laptop Screen Extender Monitor, 14'' Triple Portable Monitor Laptop Monitor Extender Dual Screen, Portable Monitor Compatible With Windows/Mac/Chrome, For 13'' -17.3'' Max Width 405mm Laptops.

Extremely easy setup and clarity of screen is spot on!Im using a 14" laptop where expanding the ctr back support is a little stiff and the rubber grips tend to slip down the of the screen, maybe a little deeper recess in manufacture will help as ive ground my rubbers out to fit the Laptop Screen edge perfectly (no slippage even when the top clip is close). I would buy again!That said, what a brilliant solution to needing screen expansion whilst travelling on business. Closed, they fit in my laptop bag and open, they are clear and big enough to work normally.Thank you!

The screens are really good quality and really easy to use. I have been using them for a few weeks now and it works like a dream. It is added advantage that there is a nice speaker integrated which means there is better sound coming out of the systems. You can choose to use just one screen or both the screen depending on your requirements.I have used it on both 17” and 14” screens and works well on both.the screen size is big enough for you to get away with all the tasks you have. You can easily pack it away when not needed and it will take less than a min to assemble and start working with 3 screens. There is also a cover provided with pocket for all the accessories which os useful incase if travelling.Overall I love this screen and will recommend to anyone who is thinking about an additional screen.

I originally saw the concept of a fold-out screen many years ago from Razr and I am happy that it has become affordable enough to buy now. After using it daily for a while it has certainly increased my productivity when working on my laptop alone. I tend to have a web browser open on one screen, my laptop screen with an IDE and the other additional screen open to a terminal. Being able to quickly see all of this at once rather than alt-tabbing is very useful. The setup was fairly easy, although I did pinch my fingers in the mechanism so be careful. It is powered by the USB-C ports so no additional plug required which is good, it worked straight away after plugging in with no need to download drivers or anything like that. When it was first plugged in, my laptop defaulted the screens to 720p and it looked fairly pixelated, so you may need to go into the display options and change that to the 1080p that these monitors support. It also comes with a leather-like carrying case so it is somewhat portable, the folded up unit is about the size of a ream of A4 paper. Overall, I think this is a good product, it is super easy to setup and use, and makes working on a laptop when you are away for desktop monitors a lot more productive!

Having previously purchased the first version of the two-screen extender I was interested to see how the updated S2 compared.The packaging is good quality and all the required cables are included. A carry bag is now included which I guess will be handy for some people.The unit has been pretty much completely overhauled, with some big improvements. The previous version had a push button release that made widening the screen attachments to fix the extender to your laptop screen quite straightforward. On the S2 you have to manually pull the sides of the unit apart, which is quite fiddly and quite unnerving the first time you do it.To connect my Lenovo laptop I needed to use three cables; a powered USB-C to USB-C (screen 1), an HDMI to USB-C and a USB to USB-C for screen 2. This is one more than I needed for the old version which used just two USB cables, but I guess if you have a laptop with two powered USB-C ports then you’ll only need those.Now to the two BIG improvements. Firstly the rubber grips that connect to each side of the laptop screen seem to be much sturdier and the problem of the bottom grips not being tight enough is no longer an issue. This improve the rigidity of the connecting between the laptop and extender.The second HUGE improvement is the screen angles. On the previous version the extender screens would sit virtually in line with the laptop screen so you could not fold them inwards to reduce glare or improve visibility. The S2 has a much improved scope for angling the outer edge of the two extender screens inwards and this improves the usability of the unit considerably.The display quality of the screens is good and they have a nice matte finish.The new version includes two integrated speakers under each screen but for some reason you can only use one of these at a time, which seems daft, so I’ll stick to using my laptop speakers.It’s early days but so far the upgrades to the screen angles and fixing system make the S2 a much better product than the previous version and a very useful addition to my mobile working set-up.

did not fit laptop which was a pity

I purchased the screens because I work from home a lot as a software engineer and my laptop screen is very small, so it's not easy to be switching between apps and tabs all the time. With the extra screen space I can have more windows open at the same time and it helps to be able to look at them side by side. The screens themselves are of good quality. It's not 4k, like most laptop screens nowadays, but it's still good enough - I personally prefer it that way because I use a virtual environment for work which does not work well with 4k screens, so it's much easier for me that way.The only thing to be aware of is that you have to be 100% sure that your laptop will be able to power both screens. Mine has 2 usbc ports, so I expected that would be enough, however I have only been able to use one of the two extra screens because my laptop does not provide enough power to support both of them. I'm honestly not sure how you can check that yours will be able to, but maybe googling your laptop's specifications will help.One other thing is that the screens are heavier than I expected. They are foldable and they do come with a case, so it's not terrible to carry them around with you, but if you need to be moving them a lot on a regular basis then the weight might be an issue for you. For me I only use them at home, so it's not a problem.
