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

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.

Pleasantly surprised. I wanted an affordable second screen for my laptop, and this met my expectations pretty well.I had an extremely easy time setting it up as I just had to plug in the USB-C to the monitor and my laptop. And it was easy to edit the settings on my laptop to copy or extend the screen.My only issue (which had me debating on returning this) was that it is not adjustable in the sense of moving it to a different side of your screen. It only works on the right side of the screen. I spent time with customer service trying to figure out if I could put the monitor on the left side of my screen, but they determined that I couldn't.HOWEVER. I found a trick, I attached the monitor to my laptop so that the extra screen was on the left side of my laptop and I went into my display settings and switched the new display to be "Landscape (Flipped)" and it is working exactly how I need it to.My desk has side walls, so putting the monitor on the right side was not an option. But this trick made it work out great!It may not be as secure as there is a tab on the top of the part that holds onto the top of the laptop, but since I flipped it, it is now on the bottom and doesn't hold in place. but the holders on the sides seem to be doing the job. I'll update if I have issues.

This laptop screen extender is an absolute game-changer for my workflow. The 14" FHD 1080P display is incredibly sharp and bright, giving me a perfect second screen for multitasking. I was so impressed by how thin and lightweight it is—it genuinely makes my laptop setup feel like a mobile workstation without adding any bulk. The plug-and-play functionality is fantastic; I simply connected it via the included USB-C cable, and it worked instantly with my Windows laptop. Having both USB-C and HDMI ports makes it super versatile and compatible with all my devices, including my Switch and PS5. The ultra-thin design and included stand make it easy to set up anywhere, from a coffee shop to my home office. This portable monitor has doubled my productivity and eliminated the need to juggle multiple windows on a single screen. Really enjoy it ^^ !

I dropped everything this morning to write this review of my Kefeya laptop screen extender. From the moment I unwrapped it and began by reading the extremely well written/documented start up literature, I was blown away...so used to poor documentation, hard to follow, often written by non-English speaking authors.After "installing" the extender on my 14" MacBook Pro which was a breeze, I'm again blown away by the attention to engineering detail that the screen extension delivers: A prop up leg that prevents the laptop screen from falling due to the additional weight (its pretty light); the small top fold out "foot" that prevents the new screen from sliding down due to its weight; the simple and exceptionally easy spring-loaded attachment to my MacBook Pro. I take this with me everywhere - in its beautiful svelte carrying case with a pocket for cables.I purchased this because I often want or need additional screen space, more-so a separate screen to deliver another look at my document, my video editing project screen, or another app like Excel when I'm working on Word and need its numbers computation.It cost $100! I had low expectations as a result of the low cost. Trust me, this accessory doesn't feel cheap - the opposite. It's worth at least twice that to me.I'm BLOWN AWAY, and over satisfied with my KEFEYA laptop screen extender!
