Can't find DAS Mode & the monitor lags.

I can't find DAS MODE on this monitor when it's already advertised in their specification.Plus this monitor lags on my system.There are better & more cheaper option out there than this which atleast provides 100Hz,while this monitor is only 75Hz. Won't give it more that 3 stars for the price & It's not up to the mark. Also,Their customer service even ain't good.So yeah,3 is more than enough.

Owned Several - All Good

I have owned several of the 27MK400H-B models. Precise color, clear text, easy to use, all of them.

Fantastic value in a large monitor!

I bought this monitor to replace an aging 24" monitor for my computer. After shopping around I found this one to be exactly what I was looking for. It had the HD resolution I wanted, connections required for my computer, slim bezel, and refresh rate comparable to higher priced models. Why pay more for the same specifications? LG is a name brand that offers brilliant performance at a bargain price with comparable warranty...what's not to like?

Great Monitor

I have had one for years, was always on the lookout for another one to match in my home office and found it. Amazing monitor, clear and responsive.

Exactly what I wanted.

I bought this monitor about 6 weeks ago to match my other LG 27" as I needed the "real estate" for my new job and I wanted it to match what I had. It came very close to a perfect match and the specs were the same, so it met my objectives nicely!

Added a third monitor

I bought this monitor to match a 27MK430 I had purchased several years ago. I needed a second monitor to match and it is very close to the original. My three monitors include the laptop monitor as screen 1. Setup was a breeze and the look and fit was what I needed. I'm very happy with my two LG monitors.

Must have

I purchased three and I couldn't be happier with them. You want to talk about easy set up these are the ones to have. I know the pictures don't do them justice but side by side there is no difference in picture quality at all. I've always used two monitors and these are the first ones that you can't tell a difference from one to the other. Like the title says these monitors are a must have.

It's OK not exactly a 75Hz monitor

This is a basic FHD monitor that can refresh up to 75Hz. Although manual says it recommends 60Hz. In any case it worked at both 60 and 75 hz on my 2018 Mac Mini. I think its a good basic monitor and don't find any issues other then I think you need to make sure it is set to 75 Hz vs the default 60Hz. If your buying it for the higher refresh rate.

Really does the job

This 27" monitor has great images. The only thing that could improve it is if it also had speakers, but that's not a problem if you have speakers to add. The images are bright, clear and the large size allows for improved viewing.

Great Screen.

I bought this a couple of months ago and have used it on 3 different computers; 1 PC and 2 different laptops and it works great. Great color, easy to use and hook up. I did have to get an adapter from HDMI to USB but does work really well.

Very poor resolution and poor black level

Bought from Costco online. Have tried every possible picture and color adjustment, but this monitor is poor. I have it right next to an old Viewsonic 22" built in 2015 and that one looks worlds better color and resolution, with no adjusting. Email text looks totally pixelated- like old dot-matrix printing. I can't understand it- it is also thin color-wise. And all-black screen looks like a grey blanket.

Good Monitor

I purchased this monitor a few weeks ago and it has not disappointed. The color and picture are both vivid and clear. The one draw back is that the stand does not adjust so you may want to purchase one for the monitor. Other than that, it's a good monitor.

Really, really bad....

After several months of use, the brightness faded significantly. Getting warranty support was extremely difficult. Long hold times. Finally got hold of someone, and they had me send it in for repairs which took over two weeks. Got the monitor back, turned it on and within five minutes it faded again! It is now being boxed up for repairs a second time, and I will be without a monitor for another two weeks. I expect that this process will go on until the one-year warranty ends, and then LG will tell me that the product is out of warranty. LG appliances are fabulous. LG monitors are garbage.

Unreliable/ DO NOT PURCHASE

Used it for about 7 months before the screen would not display anything except a faded background of the wallpaper with lines across. Only used for work for approximately 20 hours a week. And the service is estimated to take more than a month. Avoid this product and pay the extra few dollars for another brand.

Failed within a year. My Acer and HP monitors are still going strong after several years. Steer clear of this lemon.

great clear picture

I bought this monitor a few months ago and I'm very satisfied with the clear picture and easy features. It was very easy to install, all you have to look for is to set if you are going to use the hmdi cable or the av cable.

Great product for a reasonable price

I bought this monitor a couple months ago because I wanted a larger screen. I love it. I am using the HDMI connection and it's been working great. I would highly recommend this monitor for those who need a bigger screen, but don't have a big bank account balance.

Exactly what I needed

I bought this as a second screen when I?m working at home with my laptop. I recently transitioned to doing freelance work and am used to having two monitors. This one is nice and big. It?s made me more productive!

Fairly Nice

This is a good for the money monitor, there was an issue before when my computer turned on and the screen was more light purple haze over the whole screen. A quick on/off and it was normal. Now a quick switch to the new computer and it works fine. The only set back that I dislike is that the power button. You have to push it, then push up for the option, unlike a button that just turns it on/off. All in all it's a Fairly Nice monitor.

Awesome monitor!

I received this monitor about two weeks ago. It is much larger than my previous monitor. At first it felt a bit too big, but now that I am accustomed to it, it's great. It has a good, clear display. I am very happy with my purchase

Great for working from home

By nbadakhsh

I bought 2 of these as I started working from home exclusively. Nice wide view. I like the controls button on the bottom of the monitor which you can control the settings like brightness, contrast and picture mode. Some monitors the way to make settings changes is annoying, but this LG one is easy to use.

Perfect for my use

By buckybev

I am not a gamer so was not looking at the high end stuff. But this is all the high end I need. It has so many neat features. Many options for split screen use and so many other useful tools for special video settings. I'm impressed with the quality.

Full HD Display
You're in front of your monitor for hours on end. Make the most of your time, with an LG Full HD LED monitor. The clarity of 1080p pixel resolution is a game-changer. Simply put, everything looks more detailed than standard HD.

• 27" FHD (1920x1080) TN Display
• AMD FreeSync Technology
• Dynamic Action Sync
• Black Stabilizer
• On Screen Control
• Smart Energy Saving

AMD FreeSync
With FreeSync, gamers can experience seamless, fluid movement throughout hi-res, fast-paced games. FreeSync virtually eliminates screen tearing and stuttering.

Dynamic Action Sync
Minimize input lag with Dynamic Action Sync so you can catch every single moment in real-time.

Black Stabilizer
Keep visibility even in dark scenes. LG's Black Stabilizer senses dark scenes and helps make it brighter so that you can find the enemies hiding and waiting to attack your player in the dark.

On-Screen Control
On-Screen Control puts a host of essential monitor settings into a handy window for quick, easy access. Volume, brightness, picture mode presets, Screen Split 2.0 and Dual Controller and more can now be adjusted with just a few clicks of the mouse, instead of hard buttons on the monitor.
