UPERFECT Portable Monitor UGame J5 17,3" 3840x2160 60Hz, VESA USB-C Mini HDMI Eye Care External Screen for Game Consoles/Laptop PC Mobile Phone

"Finally, I found a portable monitor that’s actually built for more than just work. The 144Hz refresh rate is excellent and makes a massive difference. It's buttery smooth, and my mouse glides with ease. Everything is fluid with zero ghosting, especially games, movies are clear and flicker-free and surprisingly bright at 400 nits, especially in a room with a lot of light. The resolution on this 2.5K display is sharp and crisp, with fantastic coloursExcellent build quality, very good packaging, solid box and instructions, a quality charger and high-end thick cables, especially the 4K USB-C VGA cable, a carry case is included, it looks and feels very premium and protects the monitor very well.I haven't noticed any flickering or dead pixels after 30+ days of heavy use.The 16:10 aspect ratio gives you that extra vertical space, which is great for movies and spreadsheets; it also makes it feel much larger than a standard 15.6-inch display.It's thin, light, and the 2.5K resolution is a huge upgrade over any 1080p monitor. Definitely worth paying extra, I have it connected to my Asus Vivobook laptop, which runs a GeForce RTX 3050 GPU, and it runs smoothly and connects properly every time, with no issues.One thing to note: because it’s 2.5K and has a high refresh rate, it draws a lot of power. My laptop battery drains faster when powering this via a single USB-C cable, so I usually keep the monitor plugged into a wall outlet with the supplied cable and charger. The built-in speakers are okay and good enough for YouTube videos and similar content.I would like to see a magnetic, portable stand included or offered as an accessory in future models, so I can have the display higher or above my laptop screen instead of next to it.Overall, I am very happy with this monitor, excellent brand and worth what I paid for it, would definitely recommend.

Worked straight out the box with my android phone wirelessly. Good connection , no noticeable lag. I have even played games on it, so far battery life seems good. The matt finish on the screen is good, no reflections in a brightly lit room.The only slight downside is that the colours are not very bright but good enough. But maybe this is because of the matt finish on the screen.All the cables supplied are of good quality.And it was packaged very nicely and expensive looking.And you get a pouch to put it in.All round a good product so far.

Surprisingly good! Light weight with good battery life and like the fact it charges my input device whilst using.Inbuilt speakers aren’t great but I didn’t expect them to be. I’m working on solutions to play video via screen and utilising other audio outputs at the same time. Overall very impressed!

Very handy monitor; it comes with a sleek case and is the perfect size and weight to take to the office. The picture quality is a very high standard.The wireless feature is very good, no lag and can also connect iPads and iPhones.Battery life is superb, and would highly recommend it.

I am actually amazed at how good the screen is. The convenience of a completely wireless second screen is amazing. Battery life is surprisingly good and outlasts my laptop.It has also come in handy as a temporary monitor for CCTV and phone mirroring.It’s very easy to use with the instructions for each connection flashing up when you turn it on.Highly recommend!My only issue is the rear stand needs to be out for it to be on charge, as the stand gets in the way of the charging ports.

Really cool screen. Super thin, made from nice materials with a decent screen.quality product.

I had an issue with the first monitor I received, as it wouldn’t connect properly despite trying multiple devices and cables. The setup was far more difficult than it should have been straight out of the box.However, I was sent a replacement, and the difference was immediate. The new monitor worked perfectly with no setup issues at all. It connected straight away and has been running smoothly since.Really pleased with how this was resolved. The product itself works exactly as expected when you receive a functioning unit, and the overall experience has been positive in the end. Would 100% recommend.

Nice monitor

Excellent, light, portable, amazing colors and display. The only negative thing would be the speakers but for how thin, light and colorful this is I really don't mind.

Not the cheapest of the available mobile screens, but worth it. It's very light and the screen quality is good. 500 nits is enough for working in daylight. My Asus Expertbook delivers enough power by usb-c to power the screen which saves a power supply. Overall very happy with the screen.

très beau chouette produit mais fragile. Heureusement le support est très réactif et m'a fourni un autre

Tres content. Facile à installer. Écran tactile réactif et facile pour le transport. Tester sur mon smartphône Android, fonctionne tres bien comme une tablette. Par contre dommage de ne pas recevoir une housse de transport.

Overall I'm pleased with the 4K monitor. Very clear picture. But two cons really stand out...The black level on it isn't very good. I turned down the brightness even though my desktop is literally the color black.The side control buttons (there's five small ones) are labeled on the back so you don't know which button is which. It made for simple adjustments like the brightness to be quite annoying. Would have been alot better if the button labels were on the side.
