I work remote and travel, so I miss my multi monitor setup. Not anymore. I took this on a trip with me and it was great. The stand folded over to not take up too much desk space, the cables wear just long enough, another 6” would have been great but they worked. Quality of the screen is plenty good enough for office work, I have no gaming or artwork experience with it though. If you need an inexpensive 2nd monitor , this works great for on the go or even for a regular desk.

Great portable second screen

Size: 15.6" 1080P

Really convenient for a second screen on the go. The display looks sharp and it’s lightweight enough to carry around easily. Setup is simple, just plug and play. Not super bright, but works well for most uses.

Exceptional - Better than one twice the price

Size: 15.6" 1080P

I bought a different external monitor a few years ago for twice the price and it was abominable compared to this monitor. This monitor is absolutely perfect. The speakers are definitely tinny like others mentioned, so don't expect to DJ a party with this thing, but for work it's perfect since that means voices are clearer anyways. The sound just isn't as full/rounded with proper bass, but it doesn't even matter because there's also a headphone jack on the monitor, too. USB-C is a total game changer for powering and passing full audio-visual in a single port. The included cables are also a big win since getting a spare data USB-C cable can get pricey and I know the one included is guaranteed to work with this monitor. It was literally plug-and-play with my 2023 16" Macbook Pro. I could go on and on about how every detail of this monitor is perfect, like how the stand is also a screen protector cover and how light and easy it is to carry and how the little grippy feet hold it in place confidently, but my point is THIS is FINALLY the external monitor I've been looking for!!!

Great portable display for the price.

Size: 15.6" 1080P

This monitor works very well. I bought because I needed an extra monitor for my iPad on my work desk. But I don’t have an outlet at this desk. The iPad powers the monitor just fine, though it drains the battery pretty quickly. I ended up also buying a 20ft USB-C cable and running that to the nearest outlet to power the monitor and my iPad. I also have a little phone holder standing the display up. The quality is pretty good for the price point. Definitely not my highest quality screen. It's perfect for spreadsheets and the colors are very passable anyway.
