Rated 4 out of 5 by from Great screen Works very well and am quite satisfied. Didn't come with lightening cable so had to purchase one separately to hook up to MacBook. USB ports are new type and therefore had to buy a separate port to attach to MacBook to sync phone and ipad Once all was set up, everything works well [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Good Monitor but the "start-up is slow" I purchased the monitor a couple months back and the monitor is great but slow on the start-up. [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Excellent monitor! This is the second LG monitor I purchased in the last month, as the first one didn't have the display port plug I decided on the 34UM88. Great decision to upgrade. [This review was collected as part of a promotion.]

Rated 3 out of 5 by from like the monitor and but software design is lackin I like the monitor but the software is not loadable at startup . thus you get an annoying UAC(user account control) message every time you start it and if you are not logged in as your administrator, you have to supply credentials in addition to the annoying UAC pop-up. You should redesign the software to run in background so you only need to make setting adjustments to the running app. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Terrific display! Colours are striking! I've had this monitor for a few months now and I am extremely pleased with it. IMO its colour reproduction is amazing (especially on its pre-calibrated modes). Some IPS glow is visible but expected, and on my unit it isn't bothersome at all. Connectivity is impressive, and I love the design. The base is extremely sturdy, albeit with no pivot control (but with height and swivel). AMD Freesync is also a definite plus, although I am on team green right now I can see the value of having Freesync as a feature in this kind of monitor. Response times are good, but you may notice a slight difference if you come from a TN panel and like to play fast-paced games. Overall, this monitor excels in quality, design, and reliability. You can't go wrong with this one.

Rated 4 out of 5 by from Great with Mac Book Pro Connected to MBP via thunderbolt. plug and play. USB on monitor connected to 1 USB 3 hub with external SSD drives and the other to 1 USB 2 hub with wacom tablet, keyboard, etc. No issues. minimal light bleed (very little at bottom two corners) and good viewing angles. Have not tried display port connection to test Freesync but thunderbolt refreshes at 60hz. No problems working with video. Overall very happy. [This review was collected as part of a promotion.]
