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.
