5 out of 5 eggsGet two for productivity

Pros: Horizontal screen resolution, IPS display, several input options.

Cons: Vertical screen resolution, short stand.

Other Thoughts: I previously had two 20" monitors that ran 1680x1050 resolution. I really wanted one monitor to replace them, however if you put them both together I would have needed something that does 3360x1050 resolution. The LG 34UM95 would do that, but at $1000 that was hard to justify. One 25um64 (or any of the 64/65 series would not suffice by itself given their 2560x1080 resolution). However when Newegg put these on sale it was a perfect solution for me. For less than half of one monitor I can get two monitors and have 5120x1080 resolution. Yes a bit more vertical resolution would have been nice, but these are absolutely awesome running both side by side. I can easily pull up four browser windows, or 4 Word documents, or giant spreadsheets. Also Titanfall looks great running on a single screen. I highly recommend getting these monitors in this setup.

4 out of 5 eggsLG 21:9

Pros: Very wide display, nice picture, sleek design, vesa mount

Cons: low brightness-couldn't get it as bright as my Acer LED, game compatibility issues

Other Thoughts: No I am not a verified owner because I bought this at a local store. Plugged it in and fell in love with it instantly. But.... as I started to play different games to see how everything looked I ran into problems. Kerbal Space looked great and has a setting for this resolution. With DayZ and Skyrim I had to go into the config files and change some things to get it to work. Assassin's Creed Black Flag had a horrible letterbox effect and was unplayable. After trying many other games and spending a lot of time trying to get resolutions to work I decided this was not the monitor for me.

I will say that if you are going to use this in an office environment that it would be an excellent choice. Anything but gaming and this monitor is much better than your 16:9 ratio.

Also be aware that even though it is a 25", when placed next to a 16:9 1080p 23", the height of the 25" is less than the 23". I would recommend going to the larger 29" or 34".

4 out of 5 eggsgood high quality monitor

Pros: this is a high quality monitor with good colors.
no dead pixels. well packed and arrived fast and undamaged.

Cons: can not install windows 7 using this monitor at least not with Intel on board graphics . it will just freeze up. read other thoughts

Other Thoughts: I first tried this monitor using on a new build and installing windows 7 64bit with sp1 . it would freeze up as the windows graphics starts. so what I had to do was install windows 7 using a standard 1080p monitor then switch back to this one after windows 7 installed . it still wont go over 1080p most likely from the onboard intel graphics but it does work filling the hole screen and looks great.

this does not happen with windows 8 . windows 8 will install using this monitor .so this leads me to believe its a windows 7 issues .

ok so now lets go onto this monitors goods and bads.

its well packed and seems like high quality though not the best.
there no dead pixels. colors are bright and vibrant and seem uniform . lines are strait.

it does have sound and though not 7.1 or huge speakers. the sound does travel I noted when windows 7 turned on I could hear it down the hall 2 rooms away. not bad for small speakers.

games look good to great. I have not notices any delays

text is sharp and strait easy read . even though small

I will test with a mac and update to its compatibility though I suspect there to be no issues

it is nice having all this room. it really makes a difference. even though my main monitor is a 42 inch LCD. i am impressed with the space on this monitor and its low impact. in other words it doesn't take up much more physical space then a standard monitor yet yields more graphics space.

now for the bad

I noticed when the monitor is on with no picture that the back lite bleeds through ununiformed. this can lead to ununiformed color and text

the button takes a few minutes to get used to. it like a joy stick button . there are no standard buttons on the side or bottom. just one and it works like a joy stick. moving left to right beck and forth for the monitors settings.

I don't like power bricks even though this one is small they just tend to clutter things up.

the monitor is small. yes its wide , though still small and would be suited best for specialized graphics.

it heavy for its size

no 3D :( that's ok it to small for me anyway

aside from this it is well designed and thought out even if not the best. seems like it will last

if your looking for this type of monitor it I wouldn't hesitate to buy it .

4 out of 5 eggsVery Goodin

Pros: Very crisp resolution, lots of real estate for two windows, modern input options, intuitive joystick for controlling monitor options. Not a bad price at $230. Superb performance with no letterbox effect on 21:9 movies. Split Screen software is useful in some circumstances. Games that are made for this resolution play great.

Cons: Smallish height / text size if you're used to a 24"+ 16:9 1080p monitor. Most movies are not a perfect fit but are close, and no TV shows and very few online videos use this aspect ratio. Initial setup can be troublesome. Split Screen is useful only in rare circumstances. Games not made for this resolution are better off played on a large 16:9 monitor.

Other Thoughts: I read a lot about how to use this monitor before I got it and thought I was on track for a simple swap out but that was no the case. I have an MSI R9 270x graphics card and have gone through what it takes to run triple monitor setups already, but this unit is different. Even with an active Display Port it wasn't recognized even after the drive install. I got weird artifacts and crazy blurry images, so I unplugged every monitor I had an booted with only this one plugged in to an HDMI out to the HDMI in on the monitor. That did the trick. I am pretty sure DVI and Display Port would have worked too but I tried HDMI because I saw several conflicting reviews about that. HDMI absolutely DOES drive this monitor at 2560x1080, at least with my graphics card and a high-speed HDMI cable. Anyway, I had to go through the process of adding my other two monitors one at a time and set the overscan (in ATI Catalyst) on them to get them back up and running but after that this monitor is a very nice addition to my desktop. The included split screen software has ups and downs: It is great for perfectly splitting the screen in two when Aero Snap won't work on the inside edge of a multi-monitor setup, but the additional options are almost silly at this size. Sure you can fit two windows split vertically but it's a strain to look at most programs in a 4' high window. I love this monitor because I own a lot of movies that play on it at 21:9 and as such actually show a 2" taller and 3" wider picture than on a 24" 16:9! That's where this monitor shines. I may not be the videophile I thought I was, but I cdo not notice a lot of pixel bleed in dark movies -even Batman and TRON seemed to have consistent contrast without any more pixel bleed than mu 58" Samsung plasma. (That may seem like a bold statement but I walked back and forth several times at night trying to find something to complain about. In the end, my naked eye likes this monitor for dark movies in a dark room!) Older games (and even some new ones) don't support this resolution but the ones that do are stunning on this monitor. I will update this review after I have played a few more games; Batman: Arkham City did not like this monitor, but The Witcher II was spectacular! Projekt Red FTW!
The bottom line is at this size, this monitor fits a niche. With unlimited resources I'd go with as big a version of this as possible and never look back.

4 out of 5 eggsLG 25UM64-S

Pros: - IPS(i love IPS monitors)
- 21:9 means very wide, awesome pictures
- Matte screen helps with glare
- Displayport, HDMI, DVI it has them all.
- Built in speakers are useable for the most part
- Low GTG response time for an IPS(though this is pretty gimmicky as unless you have this monitor side by side displaying the same images, you WON'T notice any difference in response times, which is low to begin with)
- Really liked the menu buttons as it's just one but you move it to the left, right up or down or click down. This way you don't have to search for all the buttons only to press the wrong one in the menu because you can't see them.

Cons: Not all games are supported in it's native resolution

The included ability to split screens is a good idea in general, but a terrible idea on this screen. It's not the biggest, but it is very wide which makes it somewhat ideal for 2 screen split but not 4. And even then, 2 screen split was not that great. Windows snap would be easier and better than 2 screen split.

Drivers! According to LG this is meant to be a plug and play monitor but they included some drivers and software on a disk that is not only confusing to install but seems like it was a scrapped idea to include them but did anyway. There are no clear instructions on those disks, not like you need them anyway.

Plastic stand! It's not the best in the world and it doesn't have all that much tilt to it. No height adjust either.

Other Thoughts: To game with this screen if that is your forte you will absolutely need a program called Flawless Widescreen. This will solve a ton of issues with scaling and make games actually playable at 2560x1080. (though the program itself is not without flaws, and takes some time to get the fixes to actually work)

If your game is not supported by flawless widescreen or natively on the program, it will revert to 1920x1080 with letterboxes on both sides!!!

Among the games i've played, League of legends, WoW, diablo 3, these games actually support 2560x1080 without any issues and because of that you can take advantage of the higher field of view and look stunning at the same time. Assassins creed black flag also looks good but you will need flawless widescreen to make that work. My system only loses a few fps driving this screen vs my 16:9 1080p monitor.

Compared to my 23.5" dell IPS monitor, it is slightly smaller on height but like 3" longer on width. If you can get games to work in it's native resolution it really does enhance your gaming experience and it's not much harder to drive this screen vs a normal 1920x1080 screen!

Would have liked to see DVI-D cable included, at the very least and i would have loved to see a glass screen not a matte as glass screens tend to have better color reproduction as the matte screen takes away some for it's anti-glare properties.

All in all, it's a pretty nice screen ignoring the useless disks and split screen(again nice idea, but on a larger screen. This one is just too small unless you like text made for ants)

Packaging! I don't normally include it as it's a review on the product itself but my box it was shipped in had a few holes in the side that the LCD was actually facing. Fortunately the hard foam stopped whatever it was that hit it and my monitor arrived in one peice and no dead pixels! So kudos to the awesome packaging.

5 out of 5 eggsThis high-quality, ultra-wide IPS monitor is a winner

Pros: The LG 25UM64-S is an ultra-wide 25” IPS monitor; ultra wide meaning the aspect ratio is 21:9. This means there is an incredible amount of horizontal pixel space as compared to the vertical pixel space. This equates to a max and recommended resolution of 2560 x 1080. One can equate this single monitor as having the screen real estate space of two monitors jammed into a single housing sans the center bezel area that a dual monitor solution would give you.

Since the 25UM64-S is using IPS technology the colors are vibrant and full, and the blacks are nice and black with no apparent edge bleed across all viewing angles. The panel itself is a matte finish which greatly reduces glare on the screen. In both natural bright lighting and bright artificial lighting the monitor maintains color vibrancy with no wash out. Excellent results are also encountered in dim or dark rooms. The bezel surrounding the IPS panel is quite small and gives off a very professional appearance and high build quality.

The 25UM64-S features response times of 14ms (typical) and 5ms (gtg) so performance is quite good in gaming, movies, and related office productivity with no noticeable ghosting effect. These response time numbers are typical for IPS panels of this size, quality, and price. Gaming and productivity tasks all look fantastic on the vast real estate space.

The rear connections are a DVI-D, 2 HDMI, and a DisplayPort option, as well as an audio in 3.5mm jack and a 3.5mm headphone jack. With the many options for input and the included “screen split” software provided you can segment the entire screen space into 4 separate desktops in a 2x2 pattern and switch between them effortlessly. Additionally, you can also use a dual input option to connect any 2 separate devices and view both inputs simultaneously on each half of the screen. The “screen split” software provided will only work on Windows Vista/7/8 and Mac OS computers.

The housed speakers are actually a little more powerful than most monitor/speaker combinations with the 25UM64-S running both left and right speakers at 3 watts (the average is 1 watt). While most people never use the monitor speakers it's nice to have that option there should one ever need it. Moreover, the monitor is VESA compatible (75mm x 75mm), and can tilt up/down between -5 and +20 degrees.

In the box you will receive the 25" monitor, removable monitor stand, power adapter, power cable, and a single HDMI cable.

Cons: LG does not include a DVI-D cable, a DisplayPort cable, or a second HDMI cable. While acquiring each of these cables is very easy and costs very little money it would have been nice for them to be included in the box. A simple HDMI to DVI-D adapter would have been a nice addition as well in order to give customers a wider variety of connectivity options with the myriad of video cards in use with their many connection types. This small con does not warrant the loss of an egg in my opinion.

Other Thoughts: The 25UM64-S is a great option for someone who has very little desk space but still wants a large screen for a lot of screen real estate. The single base footprint on a desk is very small. While the native resolution is 2560 x 1080, the monitor will support all other lower resolutions out there (with black space cropping on the top/bottom and/or sides as appropriate).

A HDMI version 2.0 cable is required to run at an aspect ratio of 21:9. Keep this in mind if you want to replace the included HDMI cable (you want to purchase a longer cable or replace a damaged one, etc.). Earlier HDMI versions 1.0-1.4 do not support the 21:9 aspect ratio.

Overall, you would be hard pressed to find such a large monitor with a 21:9 aspect ratio and high resolution for the price. Well done LG!

4 out of 5 eggsGood monitor technical, some practicality issue depends on use

Pros: Good display quality. It's a IPS screen backed by LED backlighting, so it's very bright and energy efficient. I am using this replacing a LCD 24 inch 1980x1200 display as a secondary display on a workstation system. This display is far lighter and generates a whole lot less heat than the LCD display it replaced. The color is also natural and accurate, I turned the display from maximum brightness to about 75% for my home office lighting conditions, the display is quite bright. Not as bright as my main 27 inch LED display on the workstation, but I had to turn down brightness on both displays for my home office which has a window sitting next to my computer desk, so the brightness would not be a problem for any indoor use scenarios.
Due to its 21:9 display proportion, this display is superb for displaying two documents side by side. If you have to consolidate two spreadsheets or debug two sections of codes side by side, this display is brilliant, as it is practically two 5:4 shape displays merged into one. With win7 and above's "snap-in-place" display feature, you can easily compare two documents side by side which would increase certain productivity tasks tremendously.
The display also support a hardware based Picture By Picture mode which allows you to display two inputs in a 5:4 proportion on the display as the same time.
The display also has a lot of input choices for a computer display, sporting 1 DL-DVI, 2 HMDI, and 1 display port + 2 audio inputs (in addition to the HMDI).
The hardware scaling capability is quite nice on the display, showing original content in 1980x1080 resolution, the scaling is acceptably smooth and jaggedness free, especially in motion videos.
But it's best capability is scaling the ultra-wide feature movies and reduce the "letter-box" black bars above and below the movie contents. Due to its very tight pixel pitch, the scaled movie contents from DVD or Bluray in ultra-wide mode is quite pleasing and significantly reduces the "blank" space above the below the movie content for those types of source materials. Even when using relative low-res sources (such as the HDMI output from a regular DVD player), the output on the screen even when scaled to the Ultra-wide's 21:9 proportion is quite pleasing and smooth.
The display also comes with display resolution adjustment software for windows and Mac that will allow you to quick adjust on screen contents for best "side-by-side" display on full screen which is probably more useful on windows OS prior to WIn7 where automatic snap in is not readily available, or when the ultra-wide is used as a secondary display and Windows native "snap-to" feature does not work as well as on a single screen system.
The ultra-wide proportion definitely reduced any kind of width wise scrolling for any application.
The on screen menu is comparably easy and clear, despite of a large number of options available on the display.
The display also features very thin bezels.

Cons: There's a "shimmering" effect that washes out the image on the screen if you get close and get to about 45 degrees just above or below the perpendicular line from the screen. This is a bit surprising as if you go further above or below the perpendicular line, the effect gives away and image becomes clear again. From normal viewing angles, the display is great, but for an IPS display its viewing angle is not as wide as some other I have seen (such as the IPS thinkpad display I had on my old T60), but it is however far brighter than earlier generation IPS displays.
The vertical size of this ultra wide similar to a 19-20 inch 16:9 display, so it is definitely probably less suited for tasks like photoshop or a single spreadsheet than movies.
Gaming support is lacking, as most game would only support 16:9 proportion in its' most wide configurations.
Overall, after some use, I find it is taking some time for me to get used to the ultra-wide form factor of this display. Maybe it is just me, as it took me quite a while to fully adapt to the 16:9 display proportion from the 4:3 of the old days. Often, I feel a maximized screen on the ultra-wide 21:9 screen's native resolution is too wide for most average use (such as word processing or photo re-touching) . The ultra wide screen also makes webpage's vertical screen seems tedious, if only due to mental illusion due to the perception against the much larger width.

Other Thoughts: Note the DVI input will require Dual Link cable for full native resolution display as the screen's native resolution at 2560x1080 exceeds a single DVI link's 1980x1200 limitation. This applies to the DVI input only. The display also only comes with a single HDMI cable, with a display card capable of dual-link output on the HDMI interface, full native resolution is supportable on a regular HDMI 1.3 cable or above.
Over-all in my opinion, this is a good display for displaying ultra-wide movie contents and for side by side document comparison work. Scaling normal single window application to full screen leave the screen width exceedingly large (as least takes times to get used to), and the applications are run in more "squared" windows shape, there would be a lot of blank space on the side of window width wise.
Also, despite the 25 inch diagonal measurement, the vertical space on this display is closer to a 19 inch 16:9 display. I would recommend for large desk to use a 21:9 proportion display, a 29 inch display would be a more comfortable desktop working size than a 25 inch unit. If your desk is smaller, then this is a display of good quality and very fine pixel pitch all wrapped in a thin bezel pleasing design.

4 out of 5 eggsMy follow up with a summary.

Pros: large screen, thin panel, vesa mount compatible, simple design. excellent image quality.

Cons: a lot of backlight bleed, vague menu functions, lack of included Dual DVI cable. power adapter runs very hot.

Other Thoughts: this monitor is best used in the work place. the screen is wide enough to have 3 web pages open at the same time. multitasking is great on this monitor. text is crisp and easy to read. I do not recommend this monitor for gaming or movies, as very few games support this monitors native resolution. and often movies have dark scenes, and that is where the monitor does the worst. this monitor is not good for viewing dark scenes. when the image gets darker, the backlight bleed gets more apparent. the bleed is also not uniform across the screen.

4 out of 5 eggsPros and Cons.

Pros: Brilliant colors! I normally use my 50" 1080p tv as my computer monitor.
compared to this monitor my tv comes up short, pixel spacing,and color accuracy are real problems with using a tv as a monitor.
this monitor looks great. images are crisp and beautiful.
The monitor seems well built. the stand is strong and firm.
having a nice array of inputs on the back can be quite useful, especially if you are like me, and might have a second computer running, and want to switch between them or use the picture by picture feature.
PBP setting is actually pretty neat. if you install the driver for the monitor and turn on pbp setting you can view two different inputs at 1280x1024, side by side.

Cons: the power supply adapter gets very hot! i have my doubts on how long this power adapter will last. especially considering there are heat sensitive components inside of it. my power adapter seems to plateau around 52.8c = 127f.
these components have a heat-lifespan rating, usually something like 2000 hours @ 85c. so theoretically if a power adapter with this rating was running at 85c. which mine is not. but if it was you could only expect it to last for about 3 months.
without cutting open the power adapter and inspecting the parts, its impossible to know what the ratings are. LG does not offer this kind of advanced technical data on its products. but the good news is that the power adapter is very standard. It is a common 19v 1.7a laptop type power adapter.
If the power adapter ever fails, it should not be very difficult to find a replacement. and another positive note, is that you don't have to open the monitor and swap out a board like other monitors which have a internal power supply.

many popular titles like skyrim and starcraft2 do not support 2560x1080. in fact, out of the 50+ games in my steam library, only, 4 of them support this resolution. and if you play them at 1920x1080 you lose almost 3" on each side of the screen and that reduces your gaming experience down to a small 20" @ 1920x1080.
You can change your video setting in the menu to stretch the image, but it looks too distorted to be enjoyable. i do not recommend this setting.

the monitor's display settings can be a bit confusing. they are a bit vague on what each setting does. for example. in the menu it has a response time setting. options are high, middle, low and off.
this doesn't give enough information and can easily be misunderstood. some people might assume that high is faster. others might assume that they are describing latency, and low is better..
other people like me dont understand why this feature is here at all. we prefer a true accurate image with no enhancements.
i read the included paper guide and it does not mention this feature at all. however the monitor does come with two disks. one of these disks contains the user manual. it will be a pdf file, simply named ENG.
after reading the pdf it says that the "high" setting is best for fast moving images. but the off setting, disables "response time improvement feature"
it does not explain the details on "how" it improves the response time, which leaves us gamers, and technical guys wondering if we should use it or not. there is usually a con to every enhancement feature in one form or another. thus, the purpose of the low setting. having tried all 4 settings, i think it looks best turned off. When i first inspected the monitor i thought the screen would span all the way to the edges, but i was wrong. actually the screen stops displaying about a half inch from the edge.
so if you were going to use more than one monitor side by side, you would have around a full inch of bezel border between s

Other Thoughts: in the manual it states that for the recommended resolution of 2560x1080 a dual link dvi-d cable is required.
This information is incorrect. assuming your HDMI ports are 1.4 compliant. If they are not you will require the Dual Link DVI Cable. check your graphics cards specifications first.
It would of been nice if they included one with the monitor. considering the manual says its a requirement, but they were nice enough to include a standard hdmi cable. if your hdmi ports are not 1.4 compliant, check and make sure your graphics card has a Dual Link DVI-D connector on it. because not all DVI cables and plugs are compatible with each other.
if you are not using hdmi 1.4 or have a Dual Link DVI connection you will be limited to 1920x1080. and like i said before, at 1920x1080 you have only a 20" viewing area, or you can stretch the image, but it doesn't look good like that.. its stretched too far to be enjoyable.
