    Great monitor with few areas to be aware of

    I am writing this review after experiencing the monitor for couple of months to ensure that my review is well rounded and includes all the points one need to know of while making a decision to purchase this monitor.The context of my purchase:1. The pandemic has ensured that a lot of people like me are working from home. At some point we all feel two things (at least I felt):a. The laptop screens are too small for multi screen workingb. The switching between work and personal laptops becomes a spot of bother.2. Depending on our pastime hobbies, we need a monitor that can help us work on a bigge

    Works Great With My SurfacePro 4

    I have a SurfacePro 4 laptop and as a Realtor I needed the extra "real estate" to work with multiple screens to do research, have my PC phone on, and multi-task without having to learn a ton of hot keys. It was a pain in the butt. I used to have a couple of 27" monitors when I worked out of an office and was really missing it.This monitor has exceeded my expectations so far. I have it connected using the Cable Matters Mini DisplayPort to the monitor's DisplayPort connection. The picture is sharp, colors look good, and was extremely bright out of the box. I made a few adjustments and it's perfe

    So far so great!

    This monitor is absolutely fantastic. I'm using this as an external for my new 2021 Macbook Pro M1 16", and the performance has been flawless so far! My old Philips 4K monitor would flicker under every color profile, and I constantly had to change the color profiles to prevent this from happening on a daily basis. But this new LG was plug-and-play, super easy assembly with no tools necessary, and it NEVER flickers, no matter what color profile I set it at. It doesn't take an eternity to boot up like my old Philips monitor did. And the picture is so much better. Everything is so sharp, and the

    Finally a fantastic USB-C widescreen monitor

    I had been waiting for a time to buy a true widescreen USB-C monitor that could power my laptop and provide me with a beautiful display AND have USB ports on the back. For some reason monitor makers seem to screw it up (including LG at times), but this monitor is fantastic. I've had it for a week and am loving it. The USB ports at the back light up my keyboard, mouse, pad, and light strip on the monitor like Christmas trees once I plug in my MBP to the USB-C cable. Just that I am able to power my MBP through the single USB-C cable coming from the monitor is a game changer (and saves me the $70

    Solid monitor. USB-C only a partial solution

    I'll qualify that I knew of the shortcomings before buying, so overall I still think this is an excellent product and worth the money (@$550) depending on your needs.Pros:- Great panel- Fantastic for work- Maybe I'm weird here, but... Thank you for leaving speakers out. Who is spending >$500 on a monitor and can't afford a cheap pair of speakers- Solid stand- Functional curve- Plenty of I/OCons:- Stand isn't the best LG has- USB ports, with USB-C used for display, are limited to USB2.0 speeds- Some may not like 60Hz if they're looking to game a lot.Usability:I'm using this monitor for work alo

    Perfectly replaced 2 monitors

    I've been using 2 monitors at home for years. I saw one of these at the office and noticed how high resolution this was and decided to replace my 2 home monitors with this. I can easily put multiple applications on this as if i had multiple monitors. I really love it when working on spreadsheets as i can see way more rows and columns now which is fantastic. It was simple to hook up by merely plugging in the HDMI cable. One reboot later and my PC picked up the new monitor and i was off and computing. I have used it to watch movies on Netflix and it is excellent. I've not used it for gaming as i

    perfect for business needs

    Like many others, I'm working from home right now. Whenever I am writing, I almost always need to simultaneously look at another document. This monitor gives me enough screen real estate to have three documents all lined up next to each other, without compromising my ability to see anything. My laptop is a 2017 13" MacBook Pro, running Catalina, and everything connected nice and easy. As a nice bonus, if you use the enclosed USB-C cable to one of the Thunderbolt 3 ports, it also charges your laptop. I have my keyboard and mouse plugged into the USB ports on the back of the monitor, so that is

    Right price, right specs, USB-c, works out of the box, beautiful display

    I wanted a 4K ultrawide curved monitor but they are few and far between, mostly they are straight not curved, and mostly unavailable. And they are expensive.At 34” 21: 9 WQHD (3440 X 1440) Curved IPS display this was the best option available because the price at sub $550 was fair, and quite importantly, it has a USB C connection, meaning one USB C cable connects your computer to the monitor, without need for HDMI or Display Port.I use this monitor with my 2019 model Asus ROG Zephyrus S laptop, and it works straight out of the box. No fiddling required.Colors are sharp, whites and blacks are g
