★★★★★Perfect portable second monitor for laptop or iPad Pro
I purchased this on a bit of a whim, catching it on a seasonal sale as a companion to my iPad Pro after reading in a review that it could be powered entirely by an iPad Pro or any properly powered USB-C port. Given how light and slim it is, it would be perfect for business trips and to stash downstairs when working at night. I've now used with Stage Manger on a couple business trips and several couch or counter working session and I'm very happy with it. The brightness and sharpness are more than enough, it supports HDR, and even next to the iPad Pro's excellent display, it holds its own. I always power the display with the USB-C cable from the iPad Pro, then connect power to the iPad via the Smart Keyboards port. That setup will still drain the battery with a 15W power supply, but if you give it anything 20W or over, it'll power that setup and still charge, even with Bluetooth and WiFi active and the screens both cranked up a good bit. I also tested this monitor with a MacBook Pro and an HP Elitebook and it worked immediately, single cable, with both. This is only a 60Hz monitor with 300 nits of brightness, so while it's perfectly fine for business applications or even watching a show or movies, it wouldn't be ideal for gaming or sports viewing, with a 16"+ at 120/144Hz and 400 nits+ would be more appropriate for that application. I'm also not sure I'd use it for design proofing given that the colors are accurate, but not THAT accurate (I have a Dell Ultrasharp for that). But for my uses, this monitor is a win and I recommend it as such.

★★★★★Exceptional Monitor and Service!
This monitor was an absolute standout. Its 2K display offered truly excelling quality, easily comparable to the crispness and clarity of my MacBook Pro monitor – a feature that greatly enhanced my productivity. It was incredibly portable, remarkably light, and genuinely easy to use, making it an indispensable part of my travel mobile work setup. It's worth noting that I did have a recent technical issue arose, I am absolutely thrilled with the customer service I received regarding my recent monitor replacement. From the moment I reported an issue with my Portable Monitor 14-inch 2K Laptop Monitor, the communication was incredibly fast and efficient. The KEEPTIME-US team responded promptly to my initial query, making the process of diagnosing the problem remarkably smooth. Their commitment to good service was evident throughout the exchange. They quickly offered a solution under the product's one-year warranty, which was a huge relief. After providing a video and my order details, they swiftly arranged for a replacement, demonstrating a clear focus on customer satisfaction. This experience, coupled with the product's impressive performance when working, makes me highly recommend KEEPTIME-US not just for their products, but for their outstanding customer support.

★★★★★Great little thing
This little thing packs a lot of punch. The clarity is excellent. I got this for font editing because of the high DPI (331) and it delivers in that aspect very well. I also got it for photo editing and the high DPI is great for double checking the edit. If you set the scaling to 200% it's actually usable as a main screen for productivity apps like Photoshop. It's great for watching videos. At least in terms of picture quality- the speakers are not impressive but it has them if you need them. But the colors are amazing and I didn't even need to adjust the color profile, they were pretty accurate on factory settings. It works okay for gaming. There is some smearing/ghosting. The worst scenarios are when the scene has a lot of washed out grays, like in Dark Souls 3. You need to turn off motion blur in these games because the ghosting is already like motion blur. It was still playable but it was right on the threshold of what I would consider acceptable. I would definitely not play the whole game on this monitor. But in more bright games the smearing is hardly noticeable and the 13" screen is actually a great size for certain games like celeste and hollow knight. The form factor is nice. The magnets are strong enough that it doesn't slip. Construction feels solid. The kickstand keeps its angle and is sturdy. Overall I'm really impressed with this display for its price.

★★★★HDMI Works - USB-C Not
I could not get a video signal using USB-C. Tested with a DisplayPort to USB-C bidirectional cable. This cable works with another monitor I have. I suspect it does work because of the reviews. But the seller needs to provide details on the conditions. I also tried it with my iPhone SE and Motorola Android, got no signal, says this display. The HDMI works at 4K at full RGB (4:4:4) at 60Hz w/ 8bit color according to Windows 10. I like the rotary controls. It is quicker than the old push buttons. Rotate up gets you volume control. Rotate down gets you brightness control. Press and you get menu. The single button is to quit.
