What People Are Saying

Rated 5 out of 5 by from Amazing monitor, so great I had to buy 2! I started out with just a singel 34UC98-W and was so impressed that I purchased a 2nd one and it's twice as nice! If I had room for 3 I would probably get a 3rd! [This review was collected as part of a promotion.]

Rated 3 out of 5 by from Great Monitor! ... Until I Unplugged It. I got this monitor about a year and ago. It was awesome, and epic, and beautiful, I used it every day for gaming. I absolutely loved it. Until I unplugged it. I unplugged it, and plugged it back in, and it wouldn't turn back on. Tried several outlets, none helped at all. We have another monitor, the exact same one, so I took the cord from it and plugged that in to my own monitor. It turned on! Ok, so it's my specific monitor's cord, that's the issue. Went to plug the second cord into it's original monitor, and now that one's not working. So, both cords, or adapters, suddenly stopped working, after all I did, was unplug them, and plug them back in. Awesome. Seriously? This is stupid. I love the monitor to bits. But I HATE HATE HATE the adapters/power cords.

Rated 5 out of 5 by from Awesome Monitor!! I bought this monitor to go from two monitors to one on my desk hoping that it would be as good if not better than the dual monitors. It has not disappointed me for sure it gives me the perfect amount of working space, desk space back, and the picture is perfect! [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Excellent Display for DAW After a lot of investigation I chose the 34UC98-W to display my digital audio workstation (DAW) projects. I am so happy I converted from dual 23" monitors. Whether it's showing me 32 tracks in the mixer or an entire song in the project, the need to scroll back and forth are reduced. I was concerned the PPI would be too small but it is fine for my 50 year old eyes. The curve is more gentle than I was expecting, but the curve is appreciated for viewing the extreme left and right.

Rated 5 out of 5 by from Outstanding monitor I use mainly for video editing. Easy to setup, color calibration is excellent. Functionality and features are easy to use. Response time is good. Resolution/ definition is excellent. Use with two PC's connected with LG dual controller software which which eliminates need for second monitor on the desk.
