Rated 3 out of 5 by from Not my best experience I got this monitor through Amazon. It arrived next day is a factory box that was badly damaged. I decided to give it a try but the screen was dead at first. Tried another cord and half of the screen lit up. Called LG customer support, shared my screen to illustrate the problem and they said that the monitor should be replaced. I dropped off the damaged monitor at UPS store that same day and Amazon sent me the replacement the following day. Guess what? The box arrived damaged again! This time it looked as if it was stabbed and sliced through with a knife. I needed the monitor badly and took the risks again. Except for the tiny chip on the rear side of the monitor it looked OK. And it worked! So far my only complains are that one of the quick charge USB ports doesn’t work. And that the monitor doesn’t have any speakers. Well, those are not the deal breakers and I am keeping it. But couple days ago I received an email from Amazon warning me that if I didn’t return the damaged monitor in two weeks my account will be charged for the full amount I paid for it. //??? This is after I sent the damaged monitor back the same day it arrived! Had to spend a while on the phone with Amazon to resolve the issue and receive the confirmation that my account wouldn’t be charged twice. Not the best experience! May be Amazon should consider shipping those delicate items in additional box to prevent delivery damage.

Is 34UC80-B 34" Class 21:9 UltraWide® QHD IPS Curved LED Monitor (34" Diagonal) compatible with MacBook Pro?

Asked by: JimRH
Hi Hulemika. The LG 34" Class 21:9 UltraWide® QHD IPS Curved LED Monitor (34" Diagonal), Model # 34UC80-B has 2 x HDMI 2.0 ports and a DisplayPort (ver 1.2) port on it that either the Macbook Air Laptop or Macbook Pro can be connected to using a Thunderbolt to HDMI adapter or a Thunderbolt to DisplayPort adapter. The are adapters available for the Thunderbolt 3 ports as well. The questions is more about if the Graphics cards in the Macbook Air and the Macbook Pro can drive the monitor and if they support the monitor's native resolution (i.e. 3440 x 1440). Regrettably, we do not have information on what GPU those models use, but you can contact the manufacturer for the GPUs in the units or visit their site to review the specifications so you can determine if support the monitor's resolution and are able to drive the monitor...^AC
