KEEPTIME 4K Portable Monitor 13.4" 3840 x 2400 UHD USB-C HDMI Laptop Monitor, 100% sRGB IPS Computer Gaming Display HDR Travel Monitor w/Speakers for Laptop Xbox PS5 Switch PC Phone

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.

I don't often write reviews but this monitor is amazing. I got the 14" 2k version and the quality is very good. The resolution is better than my MacBook Air M1. It has a glossy screen that makes the colors pop, and everything look so crisp. It's very light weight and perfect for travel, I use this for work and need dual screens wherever I go. I'm super happy with this monitor.

If you need more screen real estate while traveling, you can't go wrong with this portable monitor. Works great with my 2023 Macbook Pro. Thin and light it adds no significant weight to my backpack when I travel. First trip out it saw heavy use for sharing my screen rather than expanding it, so it can perform double duty. Awesome tool for road warriors.

The screen image was very good but after a short while I could not get an image but only the message "No signal"...and that despite using various C ports combination and another cable just in case... The Sellers apologized for the issues and trouble and provided me with a full refund and that despite having used it for more than 30 days... Although we never got to know the issue(s), I give the Seller a 4 starts for their service and reactiveness.

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.

I got the 13.3" portable 4K monitor . Unfortunately, the one that I received was not "Glossy" as described in its info, instead it has a Matte surface. Image quality not as sharp and crisp as some of the others in its size range. I wasn't sure if they had sent me the wrong model as there are different variations in this listing so I requested a replacement. The second one I received also was not Glossy but is Matte so I concluded it was a description error. I then tested out the monitor a little more, running into another issue. When I switch it to HDR mode, the screen keeps flickering and stops when I turn it off. For a $160 portable monitor its really not worth the value.

This display arrived today and I tested it with my Pixel 8 Pro via usbc mirror. The picture is pretty good. Speakers are ok, passable. It is super lightweight and takes power directly from the phone (no extra usbc power is needed, but draws up to 10 watts). So basically one cable does everything. Alternatively this screen can be powered from a power bank and then the phone gets charged while playing videos (reverse power flow). Overall I found this monitor is pretty worthy and great for travel or watching movies outside. All cables and power adapter are included. OSD menu/setup works ok. Didn't have chance to connect it to my windows laptop.

Super light and fantastic resolution! I totally recommend this portable screen

I still haven't gotten around to tinkering with it completely but I am a fan of screens with a high pixel density so this stood out for me. It's LED which is great, it's nice and bright and crisp. Considering I was looking at spending over 300 dollars on a stationary monitor with similar resolution and this one is portable and half the price I am very happy with it. I prefer my stuff to be mobile and having this is a great addition to my setup. Not to mention I got it 40 dollars off! Big time thanks! Also it comes with all the necessary cabling.

I'm impressed with the monitor. It's light and slim enough to slip into a laptop bag with the laptop. The whole design is good except for the way it's set up to stand. The resolution is odd, up to 2160x1440 (2K), but still very useable. I have been using a mobile monitor last year but this will be my go-to primarily because it is so much lighter. ► The image quality to be excellent plus the viewing angle is better then the other, once properly set up in the UI. ► It's about half the weight of the other monitor which has an aluminum housing. It does provide protection but it also adds weights about two mounds more. ► The control buttons are easy to get at. ► The kit includes everything needed (cables) to get connected, but I still carry an extra USB 30-watt power block to run the monitor as I found the one that's included gets very warm. ► Like standard desktop monitors, the UI offers many options for customizing if desired. HDR provides the best image, but when active, I cannot set the brightness for some reason. ► For a 2K 14-inch portable monitor, this is a good deal for just under $140. ► For work purposes, the 60Hz refresh rate is sufficient. Hooking it up to the laptop was as simple as it gets. There is no driver installation or other techy stuff. In Windows it was automatically set up as the secondary monitor and I only had to select whether I wanted my desktop to be mirrored or extended. This is easily done by right clicking on the main monitor and then going to "Display Settings." Now every time I reconnect Windows automatically sets things up the way I selected. As I mentioned earlier, I am not a fan of how the cover is used as a stand. The biggest reason for my dislike is that angle at which the monitor then sits. When looking from my laptop to the external it causes some eye train over the period of a day as my eyes need to continually readjust for the viewing angle. It's great that the cover provides protection but there should be a fold out kickstand on the back that would allow for angle adjustment. The external monitor I have been using has the metal housing the monitor slides into when being stored, which is what makes it so heavy. Once in use, the metal housing has a fold-out arm, which allows the monitor to be adjusted in two dimensions, the outer edge towards or away from me and allows it to be tilted up or down. These two adjustments make for much easier viewing. My laptop sits on top of the housing, which then also allows for more airflow to the underside for cooling. The reason I'm only giving it 4 stars is because the cover doubles as a stand, which does not allow for changing the angle at which the monitor sits. All things considered, it's a decent mobile monitor.

Bought the 14” model, it wasn’t made clear or mentioned in the product details that it has a glossy screen. While it’s quite nice as a glossy screen, I was actually looking for a matte screen because I don’t like the glare on glossy ones. I’m indifferent and can’t be bothered with returning it, but I just wish that it was made clear. Buyers please take note of this!
