Rated 5 out of 5 by from graphic designer / gamer This is a terrific monitor. I am a graphic designer and it handles my Adobe products flawlessly. The color balancing is easy to work. Would love to see a built in suto calibrator so that i can change colorspaces easily for different printing situations. Love the size of the monitor for multiple working windows, i look forward to years of use from the really great monitor.

Rated 5 out of 5 by from Emmersive experience with quality hardware! I purchased this monitor for multitasking purposes. I use it with BetterSnapTool to organize my screen into 3 columns or 6 squares. Windows snap perfectly and the screen makes multitasking a breeze. I do some light gaming on it (mostly strategy games) and I haven't had any issues with the refresh rate. Maybe in a racing game or FPS it would not be as smooth. Having this monitor has changed the way I work. I highly recommend using it with a monitor arm so you can move it around easily. Picture quality is excellent, though not as sharp as what you see on a retina-type display. Quality is very good. Brightness is excellent, I never go more than 30% brightness - that's how bright it gets.

Rated 4 out of 5 by from Great TV This is my first curved monitor/tv experience, and it is really great. The curve adds a depth to the immersion that it lovely. The colors on the monitor are quite amazing as well. Ultrawide movies and games that play in 3440x1440 are slick. My one gripe would be that with the 75Hz refresh rate, certain fast moving games such as FPS, have a bit of a noticeable screen tear. I have a GTX 970 so I am not taking advantage of freesync to get the better refresh rate, so for those with AMD they might have a smoother experience.

Rated 5 out of 5 by from Fantastic monitor for office multitasking This monitor is awesome for viewing two or more apps at a time. I use it with my MacBook pro and it allows me to see everything I am working on without switching between programs. The built-in speakers are surprisingly good also. The only minor annoyance is that the monitor wiggles a bit on the stand if you move your desk at all. Mounting on a movable mount would probably fix this. Overall it is great, I would highly recommend it for office applications and home use.

Rated 5 out of 5 by from Excellent screen! I got this monitor earlier this year for my home office and it's fantastic. I use two 24 inch monitors at work and this one screen easily gives me the same productivity area with a much better picture quality.

Rated 5 out of 5 by from Serves me well Good colors, no dead pixels sturdy build. My only issue was the small freesync range, but I was able to expand the lower end using CRU successfully. Feels good. LG definitely on my good side for future monitor purchase considerations.

Can I set quad screen and assign hdmi 1 to the screen 1, hdmi 2 to the screen 2 ? Works that way?

Asked by: Josias
I apologize, but no; according to the chart on page 25 of your owner’s manual, it is not possible to use both HDMI ports, at the same time, for the Picture By Picture (PBP) functions.
