The Ultimate Portable Monitor from UPERFECT
This UPERFECT 21.5” 120HZ 1080p Portable Monitor is an incredible addition as a second or third display that compliments any workspace or battle station setup. The package includes two USB-C Cables, so you can use one for Displayport functionality, and another to power the monitor with the included 30W USB-C Power Brick. An HDMI Cable is also included. The monitor itself is nice and hefty, with a premium metal finish and build quality all around. The kickstand is very sturdy and is rigid to the point where you don't have to worry about any shaking or knock-overs. The monitor is very easy to control, as there's only one button and a switch. The button changes selected inputs, although the monitor does have an automatic input function. The switch controls all of the settings of the monitor, such as Brightness, Contrast, RGB Adjustments, HDR and Gaming Modes, and many more. My one complaint is that the User Manual does not explain the functions of the icons in the settings, which can be confusing for some users, but feel free to play around with the settings to dial in the perfect picture that suits your style. Testing this monitor with HDR content, it looks incredible, with very good viewing angles and color saturation. I tested it with both Displayport and HDMI to make sure the color quality was consistent between both formats. The 120Hz mode also makes the picture quality very smooth when used for gaming with supported hardware. 1080p for a monitor of this size is still very much crisp, granted as long as your viewing distance isn't directly up close. Overall, I'm glad I decided to choose this monitor above the other competitors, as UPERFECT makes sure to include full sized HDMI ports instead of Mini-HDMI to ensure all of your existing cables are compatible right out of the box. The display quality is incredible and rivals non-portable solutions that are similarly priced. If you were to pick one of these up for yourself, you would be seriously impressed.

The PERFECT setup upgrade
I got this monitor as an upgrade after using a 15.6" portable monitor at my desk setup for quite some time now and it definitely did not disappoint. Initially, I had thought that it would be much smaller but upon opening the box I was surprised to see just how big it was for a portable monitor. I've mainly been using it at my desk setup, but I could see this being a really nice portable monitor for anyone that doesn't have as much room or is looking to game on the go. The fact that it's powered by a USB Type C is already a huge benefit compared to standard monitor power cords that are chunky and overly thick but then you also have to remember that it has a 120HZ refresh rate which makes everything 100000x times better. I could see this being the perfect monitor for anyone that travels a lot with their gaming system or computer and would like to upgrade the entire experience. The build quality feels sturdy in hand and its surprisingly light for an entire monitor with a built-in kickstand. Also, this is hands down the best kickstand that I've ever used on any device as it doesn't slide whatsoever and is extremely stable throughout use. It's also easily adjustable which is extremely nice when trying to move it around at different angles. I usually end up VESA mounting all of my monitors, but I found no need to with this one due to the quality of the stand being so good. As for the viewing/user experience, I can't think of another monitor that looks this good at this price point. Out of the box the colors and resolution were already extremely good looking and then once I turned up the refresh rate and adjusted the contrast slightly it went up another whole level. Sidebar, but the menu was also really nice and easy to control which isn't usually the case for the many monitors that I've used in the past. It even has a switch kind of thing that saves you from pressing the button over and over again to scroll through the menus. I've already spent a ton of time watching videos on it and can say that it makes for a pretty good viewing experience. I was worried about it being 1080p and only 21.5" but I've found that to actually be a good thing since it doesn't take up too much room, has crisp quality, and is extremely clear. Overall, I think this is a VERY solid pick up if you're looking to save space at your setup or use a monitor on the go. After my time of using it I can't find a single complaint about it and was actually very surprised at how much I've been enjoying it. My entire experience has been great from the packaging to easily setting it up, and then using it as a part of the set up. The portability is an obvious benefit for most but the easy plug and play aspect of it is one of my favorite things. No need to fight with a wobbly monitor stand that takes up a ton of space since the kickstand is so easily accessible and if you did want something fancier then the VESA compatibility will give you just that. If you want to start using this screen, then all you'll need is an HDMI and a USB Type C cable to get it all started and they just so happen to both be included right in the box. This is a quality product with quality features, and I can seriously see myself using this in so many scenarios

Awesome portable monitor
I find the UPERFECT 21.5” Portable Monitor to be fantastic, mainly because of its portability and convenient size. I really appreciate how lightweight it is; it's perfect for my travels and fits easily into my carry-on. For me, the 21.5-inch size hits a sweet spot – great for watching movies and giving me a large portable display without being cumbersome. I'm also impressed with the build quality; the kickstand feels sturdy and stable, and the premium metal finish is a nice touch. The picture quality is excellent in my experience. The 2K resolution is really crisp, blacks are deep, and the 165Hz refresh rate makes motion incredibly smooth. Brightness levels are generally good, though there have been moments I wished it could go just a little brighter. I've used this monitor for both my work and for gaming – text comes through with great clarity, and the smooth motion is noticeable in games. I also found the menu easy to navigate and the setup straightforward. Overall, I think the UPERFECT monitor offers a really compelling combination of the portability I need, the performance I want, and solid quality.

A massive, 240Hz beast of a portable monitor!
I’ve used a few portable monitors, but this 24.5" UPERFECT is a different breed. It is absolutely massive for a portable display, but it’s exactly what I was looking for to bridge the gap between a travel setup and a full desktop experience. Unboxing & Travel The packaging was very secure. My shipping box actually had a decent dent on the outside, but thanks to the internal padding, the monitor was in perfect shape with zero blemishes or imperfections. It also comes with a huge, briefcase-style sleeve with handles, which is a lifesaver for a screen this size. What’s in the box: 2x USB-C to USB-C cables 1x Mini-HDMI to HDMI cable 1x USB-C power adapter Build & Design: The build feels premium. It includes a heavy-duty kickstand that is super convenient and doesn't feel flimsy at all. It also has VESA holes on the back if you want to mount it to a proper monitor arm. On the left side, you get the inputs (2x USB-C, 1x Mini-HDMI), and the right side houses the settings/power buttons, a headphone jack, and even a micro-USB OTG port. One minor nitpick: because the buttons are tucked on the side, it’s pretty hard to know exactly which one you are pressing from the front. I’ve definitely had some missed inputs or pressed the wrong thing while trying to navigate the menus. One thing I love about UPERFECT is that they don’t plaster logos all over the front. It’s a clean, stealthy look that I really prefer. Performance (Windows & Mac) Windows: Recognized it instantly at native 1080p. I did have to jump into the "Advanced Display" settings to manually toggle it to 240Hz, but once that was on, browsing and desktop navigation felt buttery smooth. Mac: It worked great and displayed the full 240Hz. Note: A single USB-C cable didn't provide enough juice from my Mac to power the display on its own. I had to use the included wall adapter and a second USB-C cable to get it running, which is totally understandable given the size of this panel. Gaming: I loaded up some Diablo 4 and it looked vibrant and sharp. It’s not an OLED, so set your expectations accordingly, but for an IPS portable gaming panel, the colors looked great. I also hooked up a Nintendo Switch which I know can only display 1080p @ 60Hz but it still performed great which will be perfect for the downtime on an upcoming cabin snowboarding trip. Final Verdict: This thing is a beast. Whether you’re bringing it on a trip to hook up a console or using it as a secondary productivity screen for a laptop, it’s versatile enough to handle it all. If you want the biggest possible screen you can travel with, this is the one.

Great support, unlucky faulty unit, would buy again (actually did)
The screen itself look great! Very sharp, true 4k, easy to set up, light. Love that you can use it with just a usb c if you don't need it to be too bright, it helps with the connectivity. I did have a problem with it, it would turn off after a while of using it, and it would get too hot. The support team was amazing, quick replies, very nice, understanding and accommodating. Helped me figure out what was wrong with the display, it seemed to be a faulty unit and the support rep was nice enough to offer a replacement or refund. I opted for the refund and got another uperfect portable monitor. looking forward to it!

Excellent portable monitor with impressive performance, great build quality
This 24.5” UPERFECT monitor has been a tremendous upgrade for my home office setup. The size feels just right — big enough for serious work or gaming, but still light and slim enough to move around when I need to. The build quality feels dependable, and the matte screen keeps glare to a minimum, which is a big plus. The performance is where it really shines. The 500Hz refresh rate and fast response time make everything look incredibly smooth. Games feel fluid, and even everyday tasks like scrolling or switching windows look cleaner than on my regular monitor. Colors are vibrant, text is crisp, and the overall picture quality is exactly what I was hoping for when I upgraded. In summary: - Amazing display quality and performance - Portable design that still operates like a full desktop monitor - Feels sturdy and durable - Matte screen helps cut reflections - Easy setup with good port options - Excellent for both gaming and daily use I would highly recommend this product to anyone looking for a high end portable monitor that offers top shelf performance and a great build quality.

Good monitor, 4K is awesome
Updated because UPERFECT contacted me and sent me a case. Original review: Monitor is fine but it DOES NOT COME WITH A LEATHER CASE as the description says. The monitor is a little slim and a little flimsy but I wanted a compact one so I'm not complaining, just pointing that out. You have to expect that if you get something that is 4K but only a few mm thick. It is easy to connect - just make sure you use a port that can produce both power and video. If you do, it works fine. The monitor is very light so it is very easy to carry in a backpack. It fits (albeit barely) in my laptop bag, so that's perfect. It worked just fine on my Windows 11 laptop.

Excellent Product… fantastic warranty experience
I’ve purchased multiple Uperfect monitors over the years and have always been impressed with the value and image quality. The displays are bright, sharp, and perform far beyond what you’d expect at the price point. Recently, for the first time, I had one monitor fail. I was honestly expecting a frustrating warranty process, but the experience was the exact opposite. Uperfect honored the warranty quickly, communicated clearly, and replaced the monitor without any hassle. That level of customer service really matters. Based on both the quality of the product and my outstanding experience with their support team, I can recommend Uperfect without hesitation.
