cocopar Portable Monitor 4K - 15.6 Inch 3840x2160 Full HD IPS HDR 99% sRGB FreeSync Computer Monitor with Type-C Mini HDMI for Laptop PC Phone Mac Surface Xbox PS4 Switch, with Smart Case

Bought this recently after researching many other more popular options. It is not the lightest or thinnest option on the market, and certainly not the most bought, but it has the most features and flexibility for the lowest cost that I found. It works instantly with my 2016 MBP and HP Spectre computer with only a single USB-C connection for both power and 4K video, as advertised. The video quality is amazing, and I love how it came with a screen cleaning cloth so that I can keep it free of dust and smears to fully appreciate the quality. With the HDMI port and Apple's adapter, I was able to plug in my iPhone and watch videos from my phone while the monitor was still powered by my laptop. Overall very satisfied with my purchase.A few downsides that are minor but worth mentioning:* Every time I switch computers, the brightness reverts to 1/10, so I have to manually adjust the brightness each time. Thankfully it's only about 4 button presses to get the brightness back to my preferred 4/10, but it's still a bit of an annoyance.* The speakers are pretty bad quality. I don't use much because my laptop has great speakers, but when hooked up to my phone it was not the best. The speakers are on the back too, which just makes it worse. It think all comparative monitors have a similar speaker quality and placement, so you probably won't find better, but worth pointing out.* The menu controls are not the most intuitive to use, but also not terrible once you get used to it. Don't need menu controls very often thanks to fast brightness/volume controls, but changing inputs manually is a bit of a pain if connected to USB-C and HDMI.Don't want to take too much away from the positives, still a solid monitor, great build quality, very cool that it comes with a magnetic protector and carry case, and the USB-A ports are a great touch for my MBP which only has USB-C of course. Looking forward to taking this with me as I travel and continue to work remotely.

I have a small home "office" in the corner of my bedroom. I needed a small monitor with a VESA mount to provide better ergonomics and more pixels while I work from home in these Covid times. This monitor fits the bill. I could not get it to work over USB-C from my 16" MBP. Other reviewers mentioned this problem as well. It worked fine from my wife's MacBook over USB-C, but not my new laptop. I wrote the seller and they immediately sent a USB-HDMI adapter and software to run from a Windows PC to update the firmware. It works great now with only a USB-C connection. In the interim I was able to use a USB-C to HDMI adapter and it worked fine at 4k.The monitor looks great and is responsive. It has slightly higher resolution than my 2020 16" MacBook Pro, but it slightly smaller. This works great for my needs. I like hi-res screens to have multiple documents open simultaneously.The monitor comes with a power supply and several cables. The portable case/stand is flimsy and too plastic, but I'm glad I have it in case I get to travel again some day. I do wish the USB-C ports were somehow embedded in the rear of the monitor so I could use it without cords sticking out of the side. Overall, thumbs up.

Worked for a total of 9 days. It was working fine but suddenly the screen had an orange tint. I changed the displayport cable for a HDMI cable but it didn't help. I tried to change the HDR setting but then the OSD locked up.I gave up and returned it.

I only use this monitor for my Nintendo Switch. I'm truly satisfied with this monitor. You need to invent a portable monitor that's chargeable!

I bought this to use with Samsung dex and my Note 10+. I've been testing few different 4k monitors and this one's got me confused. It says 4k but when using with phone with USB c the monitro caps at 1080p. Other ones upscaled 1080p to 4k and ran 4k no matter what if this one only does 1080p over USB c I'll be returning it plenty of other 1080p ones for half the price.

Wow, I purchased this with pretty high expectations. As many others have I'm transitioning to this new life of working from home. No more office space with a multi monitor set up. I needed something that could travel with me now that I have the freedom to work whenever I want.Now thing thing really hits the sweet spot. The resolution is on par with my MacBook, the brightness is blinding (in a good way). It is incredibly responsive and super easy to set up.I was really surprised to see the screen protector and and the travel case + portfolio case it came with.This seller really has gone above and beyond to provide a quality product. I was looking at other 4k screens and I'm SO glad I went with this one.--- Update 10-11-2020Downgraded to 1 star. Monitor was working wonderfully and then all of a sudden it stopped accepting a signal from my 2017 MacBook Pro. I've tried connecting via HDMI + USB C + Mini Display Port. All of which show no signal.
