What People Are Saying

Rated 4 out of 5 by from Great product/value Overall great monitor for the money. Only negative was the ability to consistently resurrect the monitor from a sleep phase in the computer. Many times, I have to force it to come out of sleep.

Rated 5 out of 5 by from so many capabilities Just a great tool - love the extra screen real estate and man is it fast the color is vert true. The only drawback is that when used with a HTC Vive the 1 HDMI port was used up so I had to go out and buy a Display port in order to get a the full benefit of the monitor

Rated 5 out of 5 by from Great adjustable monitor Needed a monitor that would adjust ergonomically, and go from 2 monitors to one. The monitor allows me to compare multiple documents at once, and even split screen when needed. The color and clarity are good in all light conditions.

Rated 4 out of 5 by from Good quality, worth the $ Good quality in terms of color management. Not as good as OLED, obviously, but a reasonable price/performance ratio. I love the large screen area.

Rated 5 out of 5 by from Love this Monitor! This the first LARGE monitor I've owned. It's like having two monitors in one. Ican have full images open at the same time and enjoy the normal size of each. I'd definitely reccomend this monitor to anyone wanting to upgrade their computing experience.

Rated 4 out of 5 by from Good monitor BUT NO 75HZ FOR NVIDIA (?!) The monitor is good for its price. I love ultrawide and I'll probably never go back to 16:9. It gives you so much more room to work on and it is much more immersive when playing games. The colors are nice because it is an IPS screen. Now I have seen with my own eyes what the difference is between IPS and TN and I will never buy a TN screen anymore. The screen is sadly not borderless like advertised on most of the images. (This I knew before buying the monitor.) The monitor isn't very stable and easily wobbles but not much. !!WHAT I DIDN'T KNEW BEFORE BUYING THE MONITOR!!: The screen is advertised to have a refresh rate of 75Hz, but apparently this is only available when you use FreeSync. This is nowhere to be found on the product page. I was REALLY MAD because of this. I knew 75Hz was only available through a display cable, but not that you would need to use FreeSync. (I have a Nvidia GPU.) (Still don't know if it really is the case but I see no other options or reasons why it does not work for me. So if anyone can give some help or a comment...thx in advance.) Overall this is a good monitor but if you really want an ultrawide monitor from LG, than go for the 29UM69G-B.

Rated 5 out of 5 by from Love it! Allows me to multitask well I bought this about three weeks ago. So far it is working well. I like that the screen will autosleep to increase it's lifespan. It will only do this if it's not being used for a little while, which is nice. I also like the navigation. Overall it's a good monitor for the Black Friday price I got it for.

Rated 4 out of 5 by from Looks great This is a great monitor. It looks great, was easy to set up (light for its size) and the default mode settings don't suck. (the game mode provides significantly better contrast in low light and the other modes look good). The only two issues I have are that the Vesa mount gets in the way of some of the connectors and I have not found a way to turn off the loud *ding* when the monitor turns on.

Does it have 1 main + 2 subs Picture-by-picture mode using all three inputs (1 DP & 2 HDMI ports)? I'd like to display 3 screens from all 3 inputs.

Asked by: P_J_Lee
The PBP (Picture by Picture) function in the LG 34" Class 21:9 UltraWide® Full HD IPS LED Monitor (34" Diagonal), Model # 34UM68-P will Display the screens of two input sources. If an input is connected to HDMI 1, the main screen will be on the left and the other input can be either HDMI 2 or Displayport which will be established as the Sub Screen. If the main screen is through the HDMI 2 input, the sub screen can be either from an HDMI 1 input or a Displayport input. If it is from the Displayport input, then the Sub Screen input can be either from the HDMI 1 input or HDMI 2 input...^IFV

Hi, I'm not able to use the 75Hz, only 60Hz. I am using a display cable and I have an Nvidia GPU (GTX1080). Is the 75Hz only available when u use FreeSync? Because this statement is nowhere to be found on the product page.
