I have owned this monitor since 2018 and it is working perfectly. I just decided it was time for an upgrade.

The34UC89G-B 34" 21:9 Curved 144 Hz G-Sync IPS MonitorfromLGfeatures a curved, ultra-wide display that's suitable for both work and play. For work and multitasking purposes, an ultra-wide display lets you have multiple windows side by side, or one large window where you can see all the details. On the other hand, gaming on this display will feel more immersive as the curved sides wrap around your field of view, putting you right in the middle of the action.

With a 2560 x 1080 resolution, the 34UC89G-B provides you with crisp and clear pictures. It's constructed with an In-Plane Switching (IPS) panel that has wide viewing angles and immersive colors. Combined with a 1000:1 static contrast ratio, 300 cd/m² brightness rating, 8-bit color support, and a 5 ms response time, you'll be able to enjoy vivid, lag-free content reproduction with darker blacks and brighter bright colors.

Furthermore, this monitor supports NVIDIA G-Sync technology through DisplayPort, which synchronizes your graphics card with the display to output content at variable refresh rates, eliminating screen stuttering and tearing. It also has two USB 3.0 Type-A ports so you can connect peripherals and mobile devices. Connect this display to your system via DisplayPort or HDMI and adjust it to your viewing preference. Otherwise, you can install a different mount or stand using the VESA mounting pattern holes on the back.

Curved Ultra-Wide DisplayThe curved, ultra-wide screen allows you to multitask more efficiently than before. Have up to three windows side by side or even work on large Excel spreadsheets without having to scroll.NVIDIA G-SyncWith NVIDIA G-Sync technology, the monitor's refresh rate will sync and lock with the graphics card's output frame rate. Establishing this sync removes tearing and stuttering, which can result from conventional fixed screen refresh rates, especially important for gaming in stereoscopic 3D. An additional benefit of G-Sync is reduced lag so gamers will benefit from the improved command response time as well.Fast 144 Hz Refresh RateA 144 Hz refresh rate eliminates lag and motion blur making first person shooters, racing, real-time strategy, and sports games feel more fluid. 60 Hz is recommended for games that are slower paced, whereas a 144 Hz refresh rate is more suited for games that have a lot of fast motion and actions. For smooth gameplay, G-Sync requires a GeForce GTX 980Ti and above to overclock the refresh rate up to 144 Hz. Furthermore, this display can reach up to 166 Hz when overclocked.On Screen ControlOn Screen Control puts the monitor's settings into a window for quick and easy access so you won't have to struggle with physical buttons anymore.Advanced Gaming FeaturesCrosshair - Add a crosshair in the center of your display for better accuracy in First Person Shooters.
