This is the most budget friendly monitor in LG's UM (Ultrawide Monitor) series. I wanted to try an ultra-wide monitor for work, and so far this monitor is fitting the bill superbly.

What's great about it:
- Screen real estate, it's a real life/work changer. I was a little skeptical at first, but I needed a new monitor anyways and I was getting tired of switching between tabs and windows. The wide screen means you can comfortably fit two normal fullsize windows side by side.
- Great IPS panel screen. A monitor as wide as this needs accurate colors in all viewing angle and I have no complaints. The screen has the capacity to get really bright and has decent black levels.
- The OSD (on screen display) is actually not at all bad. There's a single knob below the center of the monitor that functions as the menu navigation + power.

Reasons why this is so cheap:
- Only TWO inputs. You see it in the product image, but there are only two HDMI inputs. That's it. No DVI, no Displayport, no VGA. There is a headphone jack, for what I'm assuming is a gaming feature.
- A little shorter in height than I expected. Coming from a 24" 16:9 monitor, I knew I'd lose some vertical real estate but not the two inches that are gone.
- Cost cutting in the stand is obvious, although LG did try to make it acceptably sleek and modern. It's not a terrible base/stand as far as I'm concerned, but it does wobble a bit when I type.

Good to knows:
- I'm running a Displayport > HDMI adapter cable rated at up to 1080p and it produces the image just fine. I was concerned I'd need to get an adapter that supports a higher resolution.
- This monitor is targeted heavily at the budget gamer, as it shows in the various and prominent 'Gaming mode' settings.

We purchased 4 of these for my husbands computer desk. He loves them! No complaints! Fully mountable and pretty light weight as well.

The only thing that kinda stinks about them is the power switch is on the bottom. So if you plan on stacking them like this you cannot stack them too tight or you cant power them individually. The power switch is a joystick like button.

the pics are a 24 samsung monitor behind this LG

Beautiful monitor. Takes a little getting used to for the widescreen but you will not want to go back to standard after having one!

What I use it for

Ebay, Web browsing, adult movies (I mean come on what guy wouldn't want to watch it on a epic wide screen), regular movies, youtube, and working on spreedsheets.

Occasionally I play skyrim and it looks amazing!

Colors are amazing and all the features this monitor has makes it the best monitor for the price hands down! I am very satisfied with it.

And it looks amazing sitting on my desk.

yes it will wobble if you have a wobbly desk, type like a gorilla or beat your meat and smack the desk. Otherwise very solid!

In a few words, this is a wonderful monitor. I remember when ultra widescreen monitors first started popping up here on Amazon about 2012 but the prices were far beyond what I could hope to afford. Fast forward to recent times and the prices have started to drop a bit. The prices are still a bit steep but when I saw the LG listed for a bargain from a seller because of being an open box, I bought it.

If there is one thing I'll complain about right away, it's that LG is vague about the requirements or trouble shooting for using this monitor. I downloaded the manual and skimmed it, but I didn't see anything outstanding. When I hooked up the monitor to my 2009 Mac Pro with it's original GT 120 graphics card (with an anemic 512 Mb of RAM) it worked... sort of. It only pushed out a maximum of 1080 x 1920, no matter what I tried with both the System Preferences and fiddling in the monitor's menu. (The little toggle switch at the bottom is kind of cool -- I had no problem quickly figuring it out since I knew ahead of time where it was located and how it should work). It was deeply annoying as I knew it should all work.

After using it like a standard widescreen (stretching the resolution to "fill" the ultra widescreen distorted everything and was too annoying to put up with) since the day it had arrived, after posting to Apple forums requesting advice and finding out there were others with the same problems and even upgrading the aging graphics card to a much more powerful EVGA Geforce GTX 960 with 4 gb of RAM and still not getting joy, I was almost ready to give up on this monitor. Then, ironically, I tried something stupidly simple: I had one HDMI from the Mac Pro to it, and I plugged in a second and brought that down to the second HDMI port on the LG.

Great monitor, better then expected. But it's extremely thick for no real reason. Colors are beautiful, blacks are deep, great for Netflix, pictures, and gaming.

I upgraded from a Samsung 1920x1080 TN panel 60Hz monitor. I gotta say it's one awesome monitor. I used a modmount to VESA mount the monitor out of the box, so i have nothing to say about the stand.

The IPS display... my GOD it's such a treat to experience for the 1st time after using TN for most of your life. It came calibrated almost perfectly (minus the gamma) out of the box. Im experiencing NO backlight bleed and the viewing angles are superb.

Productivity wise, its basically having two bezeless square monitors side by side, so two windows can sit full size right next to each other. No more awkward skinny windows, where you need to zoom out to see everything.

Gaming is IMO the main reason to buy this monitor. Ultrawide IPS is something i will never trade up again after using this monitor for rocket league and Battlefield. The colors are vibrant, and the extra peripheral real estate is a huge bonus for FPS or arena style games. I havent played a MOBA or story-based single player on it yet. Keep in mind, you will need to modify the settings.ini file for some games to allow the 2560x1080 resolution.

Being a value monitor, it only supports 2 HDMI inputs, and the refresh rate is 60Hz, however i was able to push the refresh rate to 75Hz easily through the graphics control panel. Ultrawide IPS 144Hz is brand new, so don't expect a ton of those to be available, and they're not cheap.

The 2560x1080 is an excellent balance of PPI on the 25" size for this monitor. Just expect the vertical size to be a bit 'shorter' than you expect.
