Good product for the price.

This monitor works great. I’ve used it for a while now and I haven’t had issues with this one. Screen size is good and refresh rate isn’t bad either.

Love These Monitors - Nothing But Love/Performance Here!
First and foremost, yes these are the BEST budget CURVED monitors I felt deservers my time, effort and money. I've been into electronics and computers since the beginning of BBS's. Lol.
I wanted to upgrade and bought the dual setup during Amazon day.
Blew me away. Couple tips I'll share so that you can get the Most out of these monitors.
Tips: 1 - Don't buy CRAP cables. DON'T. Look at the specs, the refresh rates and what they are capable of - speed!!!; 2 - Make sure you have a GOOD quality GPU. If not you won't even be able to enjoy the investment of the these monitors. Invest in a GPU of at LEAST 8GB 1080p min with BOTH DP and HDMI ports.; 3 - With that being said, these monitors use MST!! Daisy chain them together off the DP port for an AMAZING viewing pleasure. If not, you CAN you both ports. Run your main to from the DP port (WAY BETTER quality than the HDMI) and the other using the HDMI 1.2. Again, CABLES ARE IMPORTANT. Crap cables = degregaged signal/sound loss. 4 - When you get it/them make SURE your GPU drivers are up to date. Configure on your operating system and BOOM.. ready to rock.
I researched PLENTY of options and I'm ESTACTIC about these.
I believe the deal I got was UNREAL for the price, QHD monitors and almost ..almost everything I needed. 1440p - incredible.
Ebay/AMZ for a GOOD GPU card and cables.. well worth your time.

Great value and great monitor
Size: 27"/QHD/200Hz
As a note to new buyers: a chemical-like odor may be emitted from your monitor's exhaust for the first 2-3 weeks--at least mine did. I did some research and this was likely attributed to some cleaning chemicals from the factory, and it is burning off from the heat of the monitor. Simply have good ventilation in your room, and the odor should dissipate in 2-3 weeks. I've had this monitor for over a year now, and there is no odor anymore.
Now, for the actual review: This monitor is great quality for the price! Not perfect, as I've found this monitor doesn't display smooth gradients of dark very well. For example, when I'm in a dark room in a video game, the dark ambient colors show slightly pixelated rather than smoothly blended.
Other than that, this monitor works like a charm! Colors are great, and monitor settings are easily adjustable. One complaint I have is that I can't change the monitor's brightness using the Windows OS' brightness settings--you have to change the brightness/contrast using the monitor's buttons.

I bought this for my son as a second monitor. Graphics are sick! Feels like you're really in the game.
My son absolutely loves it.
