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

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.

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.

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.

Rated 5 out of 5 by from great design and good for gaming and work!!! ive only had this for a few days,but it came very well packaged,safe and secure,set it up the next day and mounted it to the 100x100 vesa,screen looks great!!everything is very vivid,if ya have something to calibrate it i would do so,i used my spyder 5,makes the already good picture look even better.very surprised at how light weight this screen is,the vesa mount i have this on is rated for 27 in. displays,i love that lg made this so light that you can use pretty much any mount as long as it supports 100x100 and the mount dont protrude to much at each mount hole or it'll need raised 1/2 inch to clear the back monitor,picture attached to show you what i mean,i came from a Acer X34 that i had nothing but issues with,so,was looking to get it replaced sadly after dishing out all the cash for it,and i came across the HP 35 X Omen UW screen,just not enough reviews and lack of info,this LG screen had a good bit on amazon and newegg,and thou i use Nvidia cards,i overclocked this in its native res to 80 hertz and there is not a bit of ghosting of frame skipping,and productivity is great on this screen to,no BLB common of IPS,all pixels are good...i got exactly what i needed and wanted in a panel and ive used a side display beside mt X34 which was a LG 29um68 and i loved it for ease of use compared to most other monitors,LG's OSD is very easy to use and is very fast to get to where you wanna go in the menus to change anything fast,and good software now if you choose to use,great panel!!i give it 8/10!!:)

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.

Is it possible to switch the input ports fast? The older models have uncomfortable sensor keys and menu strukture to do this. A remote control would be nice too! A Monitor like this makes sence to use it for changing different sources.
