5 out of 5 eggsExellent Monitor

Pros: I have owned for 4 months and I am still impressed with it. I purchased from a competitor because of store credit. Great multitask monitor. The resolution, while not as good as the 34UM95, is more than adequate for everyday tasks, gaming, and document editing. Two word documents or web pages will easily fit side by side for office productivity. Height is similar to a typical 27" monitor, and the width is about a 1/3 larger. Picture quality is outstanding. Connection inputs are also good. The lower resolution enables use with less powerful graphic cards.

Cons: Photo/graphics editing may be the only activities where the superior resolution of the 34UM95 may be a must. Height does not adjust much and my be an issue. I experienced electrical back feed to the video card with computer shut down using the HDMI cable (LED's on video card were lit up with power off). Using duel link DVI cable or Display Port cable fixes this issue.

Other Thoughts: Many reviews state that this monitor will not display at full resolution with the supplied HDMI cable. The 21:9 monitor is relatively new to the market. Older video cards may have trouble with this, particularly those built with HDMI 1.3 standards. I purchased a AMD R9 290 to drive this monitor and it set up and displayed flawlessly with HDMI.
Also, some reviewers state being able to notice the individual pixels because of the resolution. They MUST be fogging the screen with their breath! With a typical setup on a desk, your not going to notice. My monitor does not suffer the backlight bleeding that some reviews speak either. Games and movies look awesome! I get average frame rates in newer games of between 45-60 or better with all filters and eye candy turned on and maxed out. Newer titles should adjust automatically. Older ones may not support 2560 x 1080 or play with a "stretched" 1920 x 1080 resolution. Windowed mode is always an option.
This monitor is a bit pricey compared to a typical 27" dual monitor setup, but the overall experience is far better.

5 out of 5 eggsBeauty

Pros: I got this monitor on sale for $550. It was a big price to pay, and I had a lot of hesitation going in. I'm a college student on a budget, but I wanted a nice monitor. Studying to work on Game Design, I wanted something to perform the following:
- Have accurate color reproduction
- Have multiple inputs (Not going into this further for obv. reasons)
- Have little to no ghosting
- Have LOTS of screen real estate.

I was going to get the 29" right as this beauty went on sale. Here it is, about 2 months later, and I do not regret splurging on this whatsoever.

For gaming, there is little to no ghosting. I play Guild Wars 2, and this monitor is an outstanding addition. It's totally immersive as it fills nearly your entire field of vision (or, at least, what you generally pay attention to. It won't fill all of your peripheral).

I then fired up Photoshop and Unity, configuring setups. I found nice setups with both... with room to spare! The 21:9 ratio, I feel, helped a lot.

The color, also, was BEAUTIFUL when the brightness was high enough. I tend to turn it down to minimum brightness when I'm just staring at a wall of text or doing school work, but when working with color or playing a game, setting the brightness to ~30-40 percent gives an amazing experience.

...Even now I'm still impressed that an IPS panel has so little ghosting.

Cons: In regards to the cons... I'd like to start by saying this line.
21:9 is NOT for everyone.
21 by 9 is NOT for everyone.

For me, it was a perfect fit. However, I'd recommend weighing your options first. Due to the nature of screen measurements, this monitor doesn't have as much vertical height as you might expect initially. Find some online calculators and find the actual width and height of the monitors you're considering. This monitor has the height of... I believe it was a 27" 16:9 monitor. Don't quote me on that, though. I didn't actually do the math for it at the time of writing to double check the validity of that statement.

Another thing to consider is the overall size. Consider your desk. Will this beast fit? It's thin, but it's still huge. The panel itself is 31.25 inches WIDE. Then add the bezel. (The height is about 13 and a half inches or so, by the way).

Other Thoughts: I almost regret not getting the 34UM95 instead, but I don't think my little GTX 660 could power that in games well enough for it to be enjoyable. If you have the graphics horsepower, save up for an extra few weeks and get the um95 instead, because you can see the pixels on this monitor if you get close enough.

Also, if you fall in love with 21:9, you'll never want to return to 16:9 or 16:10, and 4:3 will look absolutely abysmal. I don't think I can ever personally return to using 16:9 as my daily driver. The extra width is the best thing I could have asked for.

5 out of 5 eggsIncredible display!

Pros: -Great picture and color
-The 21:9 ratio is good for productivity and gaming
-Stand is sturdy and sleek
-Thinner bezel looks nice
-No ghosting or bleed in any of the 4 corners

Cons: Power/Menu is a little strange as it's one button that works like a D-Pad on a game controller. Took a bit of getting used to, Still 5 eggs hands down!

Other Thoughts: I bought this monitor mainly for gaming, and some reviews had me worried about the ratio and support. I've had it for a month now and had no issues with it other then some menus being chopped. Display looks gorgeous and I don't think I'll be able to go back to standard screen ratios! Get this, you won't be dissapointed!!!

5 out of 5 eggsGreat!

Pros: Large size
Great resolution
Cool split screen software

Cons: None so far

Other Thoughts: I love the size of this monitor. It's replacing two 25" HP xis. The resolution has It's great for watching movies and hasn't been bad for the games I play: (Mortal Kombat, Batman Arkham Origin, Grid 2, etc).
The software actually works with all programs. I had a 29" widescreen and it's split screen software only worked with IE and windows explorer!

5 out of 5 eggsDon't Buy 3 Monitors, Buy This One

Pros: When I first saw the Curved version of this Monitor I quickly fell in love with the 21:9 Screens. Based on what I could afford I went with the 34UM65-P. Not One Regret. I had a TV and 2 Monitors prior, this Monitor Rocks. I am able to split the screen into 3 screens as if I had 3 Monitors. It is a beautiful display, I love being able to watch newer movies at 21:9, it fills the whole screen, No Bars. This Monitor even has its own speakers which are ok if you don't have any speakers. Now onto Gaming, I have a 760 video card and everything from BF4, Crysis 3 to Titanfall works Perfectly filling the whole screen, very smooth, no noticeable lagging. I went from a 2ms Monitor to this 5ms and truthfully I cannot see a difference. Maybe it is the Awe of this big screen. All games mentioned I am able to set them to the Highest settings at 2560 x 1080. Doing the Math, I was looking at getting another 3 monitor type setup but I am so glad I had this option for around the same cost of the 3 monitors. Again, No Regrets. If you can afford the 34UM95-P or the Curved 34UC97-S Great, but in my opinion, this is the best monitor for the price. You could get two of these for what the 34UC97-S cost. Oh, I highly recommend only connecting this Monitor to a Gaming card by a Display Port Cable.

Cons: None

Other Thoughts: Just be prepared to have everyone who sees this monitor say, Wow...Oh and yes I have this same review on LG's site.

5 out of 5 eggsAmazing Moniter

Pros: I love this monitor, coming from a 42 720p tv this thing is a dream. Its colors are amazing straight out of the box and i have no back light bleed at all. I use this on games like Guild wars 2, WoW, The Crew, and League of legends and it is fantastic. I plan on buying the larger resolution model in the future

Cons: The one thing i didn't like is that for some reason i got a Japanese model so i have no English menus....not sure why but i came with a power adapter so its not that pig of a deal and i found a pdf of the manual on Lgs website.

Other Thoughts: Amazing for immersive game play and not much harder to run than a 16:9 1080p moniter. Defiantly worth picking up if you look into immersion or even productivity

5 out of 5 eggsLove it!

Pros: Good balance in height and width. I really like the stand. It looks like the monitor is floating. I haven't had any of the light bleed issues people keep complaining about. I have been gaming on it for over a week now and it looks great. No ghosting or tearing. Everything is silky smooth

Cons: I can't the screen splitter software to work. It installs and pulls up but I don't get any options on screen configuration. I upgraded from a 21:9 29" dell with similar software that I uninstalled so not sure if that is causing an issue or not.

3 out of 5 eggsW I D E

Pros: Very wide obviously. screen is as tall as a 27" monitor so a little extra height coming from a 24" 1920x1080 BenQ LCD.
IPS versus TN, well the IPS just looks better, the blacks are black not dark grey and the whites are very white. I purchased this monitor as an all around screen that I can use to remote in to work to utilize my 2 screen setup at work (GIS / Oil and Gas). RDP will utilize this resolution so that was an awesome surprise.

Cons: Light bleed in bottom left hand corner. This is a common theme when researching this monitor and the 95 version. The issue is not the screen it is the bottom part of the bezel that seems to snap in too tight against the screen. when the bottom plate is removed the screen is perfect so this is a fit and finish flaw.

Other Thoughts: coming from 1920, 2560 seemed a little ludicrous at first but i found it to be very useful and really takes the need I had for a second monitor out of the equation which is really nice. the over all look is very nice and playing games like Insurgency and BF4, which will use this resolution, are a new experience. great all around monitor except for the light bleed. This issue needs to be addressed and is the only reason I gave it 3 eggs. I really shouldn't have to take something a part that costs this much right off the bat.

3 out of 5 eggs

Pros: Large bright, clear picture.

Cons: OSD very badly designed for switching inputs.

Other Thoughts: Talk about buyer's remorse; I love the large screen real estate and I have no complaints about the picture quality, but in hindsight, I could have been happy with a 27" monitor if it allowed me to switch computers more easily.

This monitor allows you to connect to two (or more) computers, but the method used to switch between them is so bad that I would not have bought this monitor if I had known how involved it is. The problem is that you need to click the OSD joystick control eight times (!!!) to switch between computers! I tried a KVM, but that resulted in a black screen.

in summary, if you plan on connecting more than one computer to this monitor, I recommend against this model unless LG corrects this glaring deficiency.
