ATL Rob from
Regretful purchaseI have had this monitor for a year. It has been in one place since purchase. A few months after purchase it started losing power occasionally. Now it's a battle to get it to turn on. The power in port does not function well and is getting trickier as I'm forced to spend more time trying to find the exact spot the cord needs to be in to make the monitor function. I should have tried to turn this back in on the warranty which has now expired, my own fault there, but this should not be an issue with such an expensive monitor.
This is not the first product from LG I have had issues with and has required expensive repairs.

Great monitorI love this monitor, great color, the speaker is ok I use it as a TV too. The only thing is the flashing power led makes it hard to fall asleep cause it's pretty distracting.

Best Display I've Ever Had!For 12 hours a day I work in Audio, Photo and Video Editing staring at a screen all day. The studio where I work has a slightly older model of the 34'' ultra-wide (34UM95-P).
I fell in love with that display and decided that I would buy one for my home setup. So far this display has given me everything I expected from it. Sharp, great colors and the dual thunderbolt ports and extra USB ports are super helpful.

What monitor would work best for me if I have EVGA GeForce GTX 970?
Asked by: Rustywell
I ran mine @ 3440x1440 with my GTX 970ti FTW till I upgraded my car to the 1080ti FTW. On Display port it ran great.

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.
