UPERFECT Portable Monitor 18.5 inch 120HZ 125% sRGB 1080P w/VESA & Stand, Large Portable Monitor FreeSync IPS HDR Gaming Display, HDMI USB C Travel Second Screen for Laptop MacBook

My main reason for buying this portable monitor is because of my previous experience with another Uperfect product. I have a 15.6 Qled 500 nits 1080p which is great and still running strong on my desktop set up. Very nice color production and brightness. Coming back to this particular product. It is big, light, easy to set up and still very portable, it just that it has 350 nits of brightness instead of 450 nits. Looking at the product description, it states that it has 450 nits of brightness and 120hz refresh rate. The refresh rate of 120hz is accurate but the brightness isn't. It only have 350 nits according to the manual included in the box. Comparing my older Uperfect Qled with 500 nits is brighter and color reproduction of qled vs. ips is a big difference. I will use it for my ROG Ally and I need a better refresh rate than 60hz. It is still bright but not as bright and color reproduction of Uperfect Qled is very accurate. I contacted Uperfect customer service and have communication with Sophia. Great communications, she understood what was my issue with the product description not being accurate and suggested a compromise. Don't get me wrong, the monitor is very nice but what sold me is the brightness stated in the product description. She states that they will correct the product description soon for better description of the particular item. Uperfect stand with their product and that is why I choose them again for another portable monitor for my needs. After this very positive experience with Sophia, Uperfect customer service. I am looking forward of getting another product from them but will go with a Qled instead of IPS and maybe 2k resolution is in order, just waiting for the up coming prime days again. Thank you again Sophia of the Uperfect customer service. Photo: Uperfect 18.5 120hz 1080p 350 nits (left), Uperfect 15.6 60hz QLED 1080p 500 nits (right), LG 2k 240hz 600 nits (top)

I tested several products before trying out this UPERFECT 4K Portable Monitor. I even ended up returning 3 of them because they weren't satisfactory (other monitors). For me, quality is the most important for me. I'm the type of person that enjoys good sound and good visuals. As you can see in my setup, I have a gaming PC attached to a wide screen monitor, a 4k OLED monitor, and the 17.3" UPERFECT monitor at the base of the two other monitors. I wanted something matte, something with Apple-like retina display, something bright and something large enough. The screen size was perfect. It was easy to set up and connected without any issues. I did have one super minor issue with the power plug; it was making a slight humming noise but works perfectly fine. Still, I'm a bit of a perfectionist. I emailed the customer support that was listed on their card/website and they got right back to me and offered to ship me a new power plug. Again, the monitor works perfectly! I was so happy with the product, that I ordered a different UPERFECT 17.5" monitor for my office. This company's products are great as well as their customer service. I'll look here first to buy monitors before other brands!

NOTE: This is a review for the "UPERFECT Portable Monitor 18.5 inch 100HZ". Many reviews on this product page reference other UPERFECT portable monitors and as such don't align with the features of this monitor. For starters, this monitor does not come with a fold-over tablet-style cover that converts to a stand. Instead, it has an integrated kickstand, which is higher quality (more on that below). As such, this 18.5 monitor does not come with a cover at all. If you plan to take it in a suitcase, you'll probably want to get something to wrap around it. I bring this up, simply because the description of this product does not say it has a cover but many questions/answers and reviews from Amazon contributors say that it does. This, again, is because many reviews and Q&A on this page reference different monitors that do have that cover. I'm reviewing the product as-described by UPERFECT... I'm not docking it for not having a cover, because they don't advertise it as such. Cover - Is the lack of a cover for this 18.5 a big deal? For me, I do need a cover. However, this is such a great monitor at a reasonable price that having to find a way to protect it in-transit is a minor and acceptable trade-off. 18.5 - Wow. This is a game-changer for me. I used to use a similar (different brand) 15.6 portable monitor. That's been great when I am traveling for work, because I have the type of job where it's a major drag to try to get anything done on a single laptop screen. The extra space on this monitor makes doing work from a desk in a hotel that much better. Brightness - My old (other brand) 15.6 was fairly dim. White pages looked pretty yellow. I made that work and it was fine. But this 18.5 monitor can go very bright, honestly, I think it's brighter than my laptop screen. Kickstand - The integrated kickstand on the 18.5 is vastly superior to the convertible cover-stand concept in most other portable monitors. The kickstand is solid and provides a wide range of angle setups. This is a big improvement over the tablet-style convertible cover/stand, which only provides one fixed angle. VESA Mounting - This is a nice feature, allowing this 18.5 monitor to be used in a home office as a third monitor, including vertically, and then easily taken down for travel when needed. This effectively expands the uses for this monitor. Ports - I also note that the USB-C and Mini HDMI ports are on the left side of this 18.5 monitor. Many others have them on the right. I always use my travel monitor on the right side of my laptop (to preserve my laptop screen as the 'home' with the portable monitor extending to the right). To me, this is the logical and natural configuration. Having the ports on the left of the portable monitor is much better. Extended/Duplicated Displays - Using Windows 10, my other (different brand) 15.6 potable monitor is unable to be duplicated to an external display. However, this 18.5 portable does that perfectly. In preparation for this review, I did a test to make sure I wasn't seeing things. Explanation: When I'm on the road, sometimes I need to connect to a larger projector or TV in a conference room via HDMI. In this setup, I have my laptop connected to the portable monitor and the TV or projector connected via HDMI. What I want and expect is to be able to setup my display settings so that my portable monitor in front of me on the table is duplicated onto the TV/projector that everyone in the room can see. This 18.5 monitor can support that setup. My other (different brand) monitor could not. I'm sure most can, but this one for-sure can. Bottom line: I'm very pleased with this UPERFECT Portable Monitor 18.5 inch 100HZ.

I like this monitor for having a normal HDMI and not just a HDMI mini, it's slim and very portable! Thing is it doesn't have a case, I didn't know I could get a free case until the company messaged me about how I like my product, they pointed me in the direction to get a free case by emailing the customer support email on the back of the instructions of the product and gave me a PDF version in the message for my convenience which was nice, after emailing the support email, I got a response quickly about how to get my free case, which is to provide an address, and in addition to the free case as a separate offer in the same email, to be in their VIP club to try out other products. I declined the second offer as I have too much stuff already that I don't want to add to the pile, and expressed that I am only interested in the free case. There was no response after that until about two days and I was told that they had a weekend that they came back from. It was a little misleading as the page the email was listed on said it was 24hrs, (picture in this review), immediately they said they sent the free case that will come within two days and apologized for not responding sooner because of their weekend, so that was nice. I gave this product 4 stars because of the little bit of a hassle to get the free case, if you're going to have a free case, just include it in the product box! The other monitor I had and returned from a different company had a free case included and I liked that, I returned the other monitor because it only had HDMI mini and it advertised that it had HDMI not specifying mini only! The monitor from UPERFECT, when I first turned it on had a brighter spot on it near the top right, but quickly paned out as I played my game. (It was probably cases by the monitor before shipping being stored in a position not natural for the screen to handle before turning it on). The sound is fair, it does have a headphone jack, I just let the sound come from the monitor's speakers when playing my game. Over all I feel it's a good purchase and great for a gaming personal space!

This 18.4″ 4K UPerfect portable monitor was the clear winner after extensive research, offering the largest screen I could fly with while still being lightweight, USB-C powered, and practical for professional work. I use it for coding, database work, data analytics, and spreadsheets while traveling and working from cafes, coworking spaces, hotels, and it has been an excellent balance of size, clarity, and portability for a mobile workstation setup. I own two. Let me break it down. For a 4K monitor at this size, the display is roughly 240 pixels per in., which is just slightly below the pixel density of Apple’s Retina-line laptops, so text, code, tables, and spreadsheet details look very sharp and easy to read. It is a 60 Hz panel rather than 120 Hz, but for productivity and professional work, the 4K resolution and high pixel density are what matter most, and the overall clarity is excellent. The connectivity has also been very practical. The USB-C port supports DisplayPort Alt-Mode, so one cable can deliver both power and video from supported laptops and mobile devices, and Mini-HDMI is available for devices that do not support USB-C video. This is especially helpful if your laptop does not have three or more USB-C ports and you want to run two portable monitors, since you can mix USB-C and HDMI connections instead of relying on a single port type. I have also used it to connect directly to my phone, which is useful for recovering data from a phone with a damaged screen (doesnt seem to matter until it does). For all of those reasons, I chose this monitor—but the reason I will keep coming back to this brand is their customer service. After several weeks of use, the HDMI port on my first unit stopped working and I was outside the Amazon return window with no extended warranty. I contacted UPerfect support and received an initial response within about 24 hours, and every follow-up reply from Sophia on their team arrived within 12 hours with clear instructions and solutions at each step. Sophia's sincere unscripted tone made me feel heard. Once I provided my order details and return tracking, they arranged an expedited replacement. I covered the cost to return the defective unit and they covered the replacement and delivery; the speed, communication, and care they provided truly felt like world-class support. Overall, this monitor delivers sharp 4K, practical features, real portability, and outstanding customer service. Based on both the product quality and how strongly the company stood behind it, I feel confident recommending it to remote workers, travelers, and anyone building a portable productivity workstation.

Excellent product! It looks beautiful. I have not had any issues with it. Even though I had two monitors given to me by my company, I stopped using them and put my new portable monitor on the desk with its stand. It works perfectly fine. It's compact and lightweight. I bought a UPERFECT Laptop Sleeve 24-inch for Laptop/Portable Monitor on Amazon and it fits perfectly for carriage. I have my carry-on and I've this as my personal item when I travel even internationally. I've never had any issues with airport security. This monitor is great for the purpose and it has value for your money. It receives my high recommendations.

My first experience with UPERFECT has been tremendous! My primary use case was going to be as a gaming monitor for a Nintendo Switch 2. Unfortunately, the firmware of the initial batch of these monitors doesn’t seem to instruct the Switch 2 of all the possible resolutions and refresh rates via HDMI. The result is the resolution is locked at 480p. I contacted UPERFECT support about the issue and they were very upfront and honest about the issue (Thank you, Sophia!). They acknowledged that they had not updated the firmware on the first batch of these monitors resulting in the resolution issue via HDMI. They immediately offered to refund the full amount and said that I could keep the monitor. They are also going to inform me when the batch of updated monitors are available. They were also prepared enough to send me a link to the firmware update and instructions on how it’s performed. I haven’t been able to get the Windows based firmware flasher to work on my Mac, even from a Windows 11 virtual machine running in Parallels, but I realize there may be too many hardware discrepancies to make that happen. Since I have the monitor in hand anyway, I decided to test it for other uses. I set it up as an extended display on my Mac, which was incredibly easy. With a USB C connection, the monitor was immediately recognized and was capable of its highest resolution and refresh rate. This connection was made on my M1 MacBook Air, which doesn’t even display at 120Hz on the built in display, yet this monitor ran perfectly at that refresh rate with 4K resolution. It made it obvious that the built in display ran at a slower rate. The monitor is bright and the colors really stand out. I also tried it hooked up via HDMI on an Apple TV, which will force a resolution and refresh rate. Again, amazing 4K picture at 60Hz. To summarize: I’ve never been more impressed by a company’s honesty and willingness to make things right, and by a product that really didn’t work for my intended use. I can’t wait until I’m able to purchase this exact monitor with the updated firmware!

I purchased this portable monitor to use with my laptop for work, and it has been a great addition to my setup. As an engineer, I often work both in the office and out in the field, so having a reliable second screen that’s easy to transport is a big help. The 18.5-inch size is perfect — large enough to comfortably view drawings, spreadsheets, and software windows without feeling cramped, but still slim and lightweight enough to fit in a backpack. Setup was straightforward and quick, and it worked immediately with my laptop. The display quality exceeded my expectations. The screen is bright, colors look accurate, and text is sharp, which makes long work sessions easier on the eyes. The high refresh rate is noticeable when scrolling and moving between windows, and overall performance feels smooth and responsive. Build quality also feels solid for a portable monitor. It’s been easy to position on a desk or temporary workspace, and it’s held up well during travel between job sites. Overall, this monitor has been very practical for productivity on the go. If you need a portable second screen for work, travel, or a mobile setup, this is a great option and offers excellent value for the price.
