34" Class 21:9 UltraWide® IPS LED Monitor (34" Diagonal)

  • 34UM67-P

Key Features

  • Freesync
  • UltraWide® 21:9
  • Dynamic Action Sync
  • ENERGY STAR® Qualified


FreeSync engineered into 29UM67 can do what it does best- it eliminates tearing and stuttering that occur from the difference between a graphic card’s frame rate and monitor’s refresh rate. With FreeSync, you will not settle for anything less than seamless movements in 3D MMORPG ever again. It usually requires more than a nice monitor to fully enjoy 3D games with high-level specifications. When using the 21:9 UltraWide Monitor equipped with FreeSync, you no longer need to upgrade your graphic card to solve this mismatch issue and enjoy high-res, heavy-duty games without going through hassles.

* FreeSync is only available when it is connected to Display Port.

What People Are Saying

Rated 2 out of 5 by from Massive Frame Skipping The monitor is great at 60hz but when freesync is enabled at 75hz there is frame skipping making me dizzy in games

Rated 5 out of 5 by from Awesome Display Got this monitor for my home office/gaming. Refresh rate and resolution are great. Easy to setup. Great value!!

Rated 5 out of 5 by from Great price, perfect size, easy to use I've used this for three months and it's been perfect so far. Most of my day is spent switching between Excel, SPSS, Dreamweaver, and InDesign. The width is perfect for having two programs open at the same time, and it's just tall enough that I don't have to scan up or down to see whatever window I'm in. Setup was a breeze, and controlling it through the joystick is simple. It switches easily between OSX and Windows. The only quibble I have is that there's no tilt, but I didn't expect perfection at the price I paid. As it is, it's pretty close.

Rated 4 out of 5 by from Just why. I bought this monitor almost a year ago, but no one, not my local seller neither this LG's official review told me that this monitor has in fact 75Hz of refresh rate. Why just why? It took me almost a year to realize that in my PC setting I can set refresh rate from 60 to 75 in couple of seconds. I'm not sure that would this work with Nvidia graphics cards, because I believe that Freesync needs to be turned on. But anyway today I got an "eyegasm" before changing the Hz settings and I become to love this product even more. I just wish that LG would tell about this secret hided refresh rate feature to their consumers.

What are the vesa mounting brackets on the back (what size)

Asked by: Madimir
The LG 34" Class 21:9 UltraWide® IPS LED Monitor (34" Diagonal), Model # 34UM67-P has an A x B Vesa Wall Mount Pattern of 100 x 100 (mm). The metric size for the screws are M4 x L10 if you will be using the LG Wall Mount Plate, Model # RW120. If you use another Vesa Compliant Wall Mount from a different manufacturer, as long as it has the same Vesa Wall Mount Pattern, it will come with the correct Vesa screws and they will have the same diameter (i.e. M4), but may have a different length (i.e the number after the 'L') to accommodate for the thickness of the Wall Mount...^IFV

I posted this as a comment a month ago and realized today that is why it has not been answered to date. I just want to know if there is any update to the software for the 4 screen-split. Does it run on Windows 10 now? Thank you. =)

i just bought a LG 34UM67 Ultrawide monitor and it seems to have a film protector for the screen but i'm not sure, i'm afraid of take it out because maybe is part of the screen, can you please tell me if is a common plastic film like in a new cellphone?

Asked by: sebasemma
We appreciate your interest in this monitor. In reviewing our information, it appears that some models have a film around the edges of the monitor, but not necessarily on the screen itself.

how well does this work in an AutoCAD application?

Asked by: hawk2
If you're going by the criteria that you need to consider on what would be the best monitor for CAD work, the ENERGY STAR® Qualified LG 34" Class 21:9 UltraWide™ IPS LED Monitor (34" Diagonal), Model # 34UM67-P exceeds those criteria. Typically, dual 19" monitors are considered the minimum for a CAD workstation, but even that setup can be limiting because CAD applications have so many toolbars, palettes, and pop-ups that screen real estate is at a premium so as an UltraWide 34" exceeds the recommended minimum of 22". Monitors with an Aspect Ratio of 16:10 are usually recommended, and again, the 34UM67-P trumps that with an Aspect Ratio of 21:9. The general rule of thumb is that the greater the resolution (that is, the more lines of pixels), the better the image quality; however, to get an accurate indication of image quality, you must consider resolution in conjunction with monitor size to determine pixel density or what is referred to as pixels per inch (PPI). This is something that you may want to consider since the acceptable PPI considered to be the "sweet spot" is between 90 to 100 PPI and for this monitor is 82. Since you'll be sitting close to the monitor, the higher the pixel density, the less noticeable the pixels are and we would recommend the LG 34" Class 21:9 UltraWide™ WQHD IPS LED Monitor (34" Diagonal), Model # 34UM95C-P which has a pixel density of 112. The response time for the 34UM67-P is great at 5 ms (the rule of thumb being that you stay between 5 - 10 ms). Depending on where you'll be using the monitor, if you're in an office space where you'll be collaborating with other people, then the viewing angle may be something else you want to consider. This monitor is an IPS panel which offers great side viewing angles...IFV

Why don't you list the ports on monitor.

People come to the manufactures site to get technical details. You don't even bother to list what ports are on the back or give clear enough pictures so the customer can tell what they are. It appears there is one HDMI and a Display port next to it but I can't be sure. I've seen mentioned that there are two HDMI ports. It would be nice if you listed this and there exact locations are with clear pictures.
Asked by: billlh
That is incorrect, There are 2 HDMI ports, 1 Display Port and 1 DVI port. the second hdmi faces sideways and is hard to see in pictures.
