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.

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 external portable monitor
I have a 1080P external portable monitor, but my main monitors in my office running f my laptop are 4k. So I wanted 4k for travel too. This one is extremely affordable. It is running off one USB-C port of my laptop. You could power it externally, but it works fine with one cable. I keep my laptop plugged in to wall socket for power. It has a very crisp screen, good quality and a nice feature I was unaware of, is the little round hole in the corner, you could run a cable lock through. I normally do that when staying in hotels. I have tried it with my iPhone . It will need an adapter for that, which they say you can request and get for free. I did get it for free. It does not enlarge the iPhone screen though, so relatively small picture. It weights 3 lbs , 12 Ounces. Overall, a very good buy.

Great extra monitor for my PS5
Really great quality monitor, I use it regularly for my PS5 Pro when traveling or the main tv at home is being used. The color, sharpness and brightness are great, and the menu to adjust settings works well. I had an issue with my first model overheating and turning off, but support was efficient and easy to work with and they sent me a replacement in a timely manner.

Stunning 4K Travel Screen That Made My Laptop Feel Inadequate
This 23.8" QLED panel hits like a desktop monitor that somehow learned to fold up and leave the house. The brightness is legit, the colors snap, and the 4K sharpness makes spreadsheets and Netflix both look overachieving. It’s big enough to feel like a real workspace but still portable enough that I didn’t question my life choices carrying it around. Built-in features feel solid, stand options are practical, and setup is brain-off simple. If you want a large portable monitor that actually behaves like a premium 24" display, this one delivers without fuss.

Good Monitor, Misleading Photos
Packed well. Has a nice hard board with foam backing to protect the monitor face in shipping. Worked immediately without much difficulty. Seems to work via both HDMI and USB-C with minimal fidgeting. I usually have to adjust the output device to get to 120 Hz, but that's common to all monitors. No difficulties with it keeping the 120 Hz settings between unplugs and reboots of the computers. Image quality is pretty good. Contrast is good. I like that the screen surface is matte, many portable monitors are glass or glossy plastic. My other portable monitors have better contrast, but I suspect that's because they are glass or glossy. Matte finish usually causes some loss in contrast. This is still pretty good. Build quality feels good. Not heavy like a normal monitor, but not suspiciously light like some. Stand seems short relative to the monitor's height... but the monitor's weight balance seems to work well with it. I have one particular gripe with the seller/manufacturer. On the product photo, the HDMI port is notched toward the *back* of the monitor. The monitor I received looks identical, except the HDMI is notched toward the *front* of the monitor. I bought an HDMI cable with a 90 degree end specifically expecting it to face the direction in the photo. The differing orientation isn't the crux of the issue... what bothers me is the photo of the product on this page is *not* actually a photo of the product they're shipping. I view this as a big faux pas in sales. My suspicion is the underlying chipset near these ports was flipped 180 between prototyping and going to production. Or between batches for some reason. Otherwise, the value proposition here seems pretty good. For the size, price, refresh rate, and quality... a great buy.

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.

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.
