    Awesome Picture, High Quality, Smart Design
    This was the first UltraWide monitor I've ever owned, and had always worked with dual standard 4:3 or 16:9 sizes. That setup will be not happening anymore based on this purchase, which I was essentially blown away by.Normally when it comes to consumer electronics, I'm a loyal Samsung customer to the core. However when one is cost constrained, the list of available options which meet all the requirements, often does not include any Samsung products. But I knew their fellow South Korean's over at LG were not ones to half measure any efforts or designs, so I ordered.The box came about 5 days after order through UPS.IMPORTANT NOTE: For those of you who work during normal delivery times, be aware that this shipped to me with no signature required. Normally not a big deal, but if you look at the photo I attached of the box it came in, you'll see that what's in the box is very clearly indicated. I asked the UPS driver even he delivered it if had I not been home, would be have just left out. He said 'Yes' like I had asked an of question. Moving on...Unboxing was effortless, as was assembling the stand and attachment hardware. The picture quality is unbelievably crisp as and fast exceeded my expectations (again, take that with a grain of salt, is never used one previous to this). LG includes an app and drivers on a CD-ROM you'll want to install after getting it initially hooked up. The app, called OnScreen Control (see picture) enables you to configure the screen layout in a number of ways, splitting it into various smaller virtual screens to fit your needs. It was pretty easy to understand, however I haven't read the manual to see what I'm missing with regards to advanced settings.The one very small critique I did have was the LG folks expected to much of me! I'm really not very savvy with all things computers or their peripherals, and had no idea which of the cables I needed, it the monitor would act as a single unit, or did my video card see it as two monitors, which offered the best picture and greatest performance?Probably stupid questions for many people, and I eventually used my Google-Fu skills to figure it out (one cable needed, between HDMI and DisplayPort, all things being equal go with DisplayPort).Lastly, and I'll leave off on a positive note, another feature which I found was better than my past experiences with any monitors, was the user interface and input mechanism for manually changing the display's configuration and settings. Instead of all buttons and the settings screens looking like an afterthought, there is a small flush 4-direction joystick under the LG logo badge which is extremely intuative to use.

    5.0 out of 5 stars Best (flatscreen) monitor I have ever owned.
    Reviewed in the United States on April 20, 2016
    I bought this monitor to replace a 32” 1080p TV which has been serving as my main monitor. I also have another 27” 1080p monitor for a dual screen setup.

    I had my eye on the LG 34UM95 but I am not a fan of the aesthetics of its stand. I also wanted (still want) the curved Samsung S34E790C but my wife gets nauseous every time she looks at it. I took a chance on this flat-screen monitor because of it’s great looking base even though I could not find any in-depth reviews.

    Pros:

    -Size. This monitor is huge. I almost have trouble fitting another monitor next to it on my desk. It happens to be the same size vertically as my 27” monitor which is nice.

    -Resolution. The 3440x1440 resolution is great for a screen this size. I have another 29” 2560x1080 resolution monitor and it feels too much like a short monitor. This 34” screen definitely feels wide, not short. The monitor will push 60hz refresh rate on both HDMI and Displayport.

    -Picture. The colors are fantastic out of the box. I can’t see any backlight bleed common to IPS panels.

    -Stand. Great tilt and height adjustment. I can move the screen from 2.5” from the desk up to 7”.

    -Comes with a DisplayPort-DisplayPort cable and an HDMI-HDMI cable.

    Cons:

    -Wobbly. My desk isn’t that steady, so any movement of the desk is translated into a lot of wobble in this monitor. I don’t notice this much in the smaller monitors.

    Summary:

    Now all I need is a couple more of these monitors!

    EDIT Sept' 2016: After 5 months this monitor is still working flawlessly. Since my original purchase, however, I have acquired the LG 34UC87M-B curved 34" monitor (pictured next to my LG 34UM88C) and the Samsung S34E790C curved 34" monitor. I really appreciate the subtle curves of these new monitors and I like how they make the screen edges more usable and less "far away". If you plan on having two 34" monitors side-by-side, making at least one of them a curved monitor is a must.

    I have the curved and flat LG monitors side-by-side (as pictured). I prefer to watch videos and play video games on the curved monitor, while I prefer to do photo editing on the flat panel.

    Other thoughts: Getting videos to play in the 21:9 aspect ratio while utilizing the full screen is a hassle. The Windows Store video player is the only online streaming platform I could find that easily goes true full-screen on this ultrawide format. Other streaming services will play HD movies in 21:9 format(ish), but will not zoom to be full-screen. See pictures comparing streaming HD movies from Windows Store and Google Play.

    Wew, I love this thing. Got a flawless panel, no backlight bleed, no dead pixels, no flaws... Man this thing is great. Had to turn down the green hue a tad though, but other than that colors seem pretty accurate. I do see the appeal of a curved screen though; I probbaly wouldve gotten a curved one if I didn't do art on my spare time. Might get a second one but curved and use two of them. Hard to go back to anything else!

    5.0 out of 5 stars Great monitor...although I'm having ONE issue
    Reviewed in Canada on February 28, 2017
    This monitor is an excellent monitor, however, I am getting little windows that pop up that are inactive (can't get rid of them). The message in these windows cautions me about using the correct cable and telling me that I have set the resolution to 1280X1024 and that the recommended resolution should be 3440X1440, when in fact the resolution is set at 3440X1280. These windows popping up from time to time make use of the computer a frustration experience. I wonder if any other people that have purchased this monitor are having the same problems and if so do you have a work-around? I suspect these windows are coming from the LG CD that comes with the monitor but can't find them.

    Other that this issue the monitor is a great buy.
