LG 27GX700A-B Reviews

LG corporate have no morals.

By JustDont
Rated 1 out of 5

As the other user mentioned, horrible experience. Along with them, my order was canceled with no notification. The rug got pulled right from underneath us. There was a coupon price for this unit that should have been honored but instead, they gave us a terrible new discount as a slap in the face and to make it seem like they "tried to help". This was purely a corporate decision and is extremely predatory.

Great OLED for Gaming and Streaming

By Garrett L

[This review was collected as part of a promotion.] We stream and game all the time. This monitor offers everything we need. The colors are really vibrant and detailed. The WOLED specifically gives great brightness for an OLED. The blacks, of course, are absolutely breathtaking. This has given a new experience to gaming for us. We stream 8 hours a day for 4 days a week and it is worth every penny. The monitor comes with a very hardy and sturdy mount. We used our our own arm mount but noticed the quality of the one that comes with it. The refresh rate can handle basically any output for any graphic card. LG is a great quality. I have two other LG gaming monitors and while I love them this monitor is special. Quality gaming is easy on this monitor. Visually stunning games are even more stunning. It is also very aesthetically pleasing as the monitor is thinner than a smart phone. I can’t recommend this product enough.—Review submitted as part of a program that provides a purchase discount.
