I LOVE this monitor so far, it came in perfect condition, decently fast shipping, all cables included. Looks great and works great. Only problem is picture by picture (this allows you to have two different sources side by side) like I could have a Playstation on one side and a computer on the other. This works, but you cannot adjust the aspect ratio of each display so they are squished and pretty much unplayable. Other than that having one display works amazing and PIP (picture in picture) works pretty great too! I HIGHLY recommend this monitor.

This is a great monitor for someone like me who doesn't know the difference between free and g-sync. The edges are crisp the usb ports on the back are clutch for things with shorter cords like phone chargers and web cams. The curve is fantastic and really does make a difference you can see the whole screen all the time! the buttons are slightly annoying and the HDR mode doesn't work for me sometimes (TBF probably user error). Overall its a great monitor if you don't pay full price, I picked it up for $350 and will keep looking for a sale like that again so I can get one for my wife!

bought this for work as i have to look at large drawings all day i am looking at getting another just because of the quality
Reviewed in the United States on November 9, 2022
Overall a good gaming monitor but make sure to use a MiniDP cable for the best framerate and to tweak all the settings to find the best quality. There's a lot of settings though and the button panel is quite difficult to navigate under the lower right of the screen. Fortunately they have a app you can download to manage the same settings, but there's a learning curve to tweak the quality you want. Also video plays a bit darker than I'm used to sometimes - not entirely sure why. Don't use HDMI cables with this one if you can manage - the framerate will be lower with noticeable ghosting in movements compared to my previous HDMI dedicated monitors that didn't ghost.

This is my first wide-screen, curved monitor and it is flawless for working on projects with business applications. I am not a gamer and wanted a monitor large enough to handle multiple windows. With plenty of room, I am able to have multiple windows at my disposal without delay on selecting.

The monitor would not power on out of the box. Tried multiple power cables and multiple outlets. Not sure what happened. The box was in great condition and no signs of damage in the box. Monitor arrived in great condition but clearly not working properly. Returned the same day it arrived.
