Used LG 34WK95U-W 34"UltraWide 5K Nano IPS LED Monitor with Built-In Speakers, 5120x2160 undefined

I purchased this monitor when it first became available. 5K was extraordinarily useful for photographic and video editing. My only criticism is when/how a firmware update using OnScreen Control froze and then damaged the 5120 x 2160 resolution mode. High-resolution images are permanently cropped in. Support has been of no help in resolving the issue despite repetitive efforts.

Extraordinary Beautiful Detail--However...

Nothing but trouble. 00000000000000000000000000000

This monitor has several significant drawbacks. 
1. Despite being marketed as 5K, it only supports HDMI 2.0, which has a maximum resolution of 4K. What prevents the installation of more modern HDMI 2.1 standards? 
2. Connecting a Mac via Thunderbolt causes the monitor to take a long time to wake up, sometimes causing confusion with the resolution and no sound. 
3. The only fully functional interface is DisplayPort, but unfortunately, it only has one connector.

Not perfect

Awesome monitor. Professionally color calibrated. Big enough to display multiple programs/documents at the same time and maximize the workflow speed.

Screen splitting software included is like having multiple monitors packed into one.

Great sound. No web cam or microphone, but those can be easily added if/when you want them.

Awesome monitor for photo editing office work

After a few days of use, I had a shadow appear about 8 inches wide, left of center, from top to bottom of screen.  I can make it go away by unplugging the power cable and letting it sit for a few minutes.  It solves this issue temporarily.  Pretty frustrating.

Pretty Good, but?.

Great monitor for all types of productivity on one screen

I've had this monitor for a while now.  However, I have been dealing with image retention (burn in) since almost the first month of ownership.   I have many LG products in my home but this was truly disappointing given the high cost of ownership.

Great Idea/Great Product - At FIRST

?and I?ve had a few. Including the ultra fine 5k from LG

Best monitor ever

I had this just over the warranty period where I got a slight hit on the side. That was enough to crack the screen under the outside screen. Very disappointed. Next time get extended warranty.

Easily broken.

I purchased this monitor a few years back to replace another LG panel that was exceptional - a 34UM95. It looked to be the ideal panel. But this panel was not ready for prime time.

It's a really good looking panel if you can get native resolution working on it. I tried via HDMI and DisplayPort through numerous cables and adapters from my previous 2018 MacBook Pro, and USB-C was the only way that it would work. I understand HDMI doesn't (generally) have the capacity to output 5k60, but DisplayPort does. Otherwise, it would downscale to a resolution that looked blurry at best, jagged and unpleasant at worst. And half the time, I'd have to pull and replug the power cable just to get my MacBook Pro to understand its resolution.

Ghosting. I sent this in for repair due to terrible ghosting issues. They... replaced the control button. Any brighter window that sits in the same place on the screen for more than a few minutes will 100% leave a ghost. It's an IPS panel and should absolutely not do this. You can search for this and find people with these problems all over the place.

Start-up time is horrendous and the OSD is sluggish. Often times it won't boot into the proper resolution.

The brightness is OK, but, even in a dark room, I've always craved a bit more from it. Compared to my Ultrafine 5K, it looks dim and gray by comparison. Don't even get me started with its "pseudo-HDR," because HDR isn't HDR when it can only put out 500 nits.

Of course the USB-C port has since broken as well. Because why not? I literally put zero pressure on the USB-C cable or anything. I just unplugged it from the back one day, and the next day, the USB-C port was jiggling around like a belly dancer.

This had the potential to be such a great monitor, but it failed on so many accounts. Ghosting/burn-in, poor OSD, cheap components, lack of proper connectivity, etc. And yet, LG decides to still advertise this monitor - despite not being sold for several years - on social media.

Checks (almost) all the boxes, but poor execution

On paper, this was the perfect monitor.
- 4k screen with USB-C connectivity and lots of USB ports
- Sweet spot from a size standpoint 
- Beautiful no-logo thin bezel 
- Built-in KVM switch for multiple computers both PC & Mac that is easy to use

In reality, it is unworkable for professional work.
- First, only USB-C is 4k. The HDMI ports are only HD meaning if you have two computers (one for work, one for personal) that you want to use in 4k you will have to manually change the USB-C from the back. 
- Second, when your computer goes to sleep when it awakes it will reset the default resolution to SD. It happened on my Mac Mini, M1 MacBook, and Lenovo laptop. You have to unplug your computers each time and reconnect them for the resolution to reset. 
- Third, the wake-time from when I clicked on my trackpad or mouse to when the monitor woke up was frequently close to 20 seconds. If it happened once in a blue moon then no biggie, but the majority of the time at this price point - really frustrating.

The most beautiful monitor on the market imo and I would pay the price in a heartbeat if it worked. But it doesn't. I read the reviews before buying and took the chance anyway. Don't make my mistake - pass on this version.

Perfect Idea with Poor Execution

I am a software developer. I work with frontend and backend. I need comfortable working conditions. One of them is two monitors on which I can perform my duties without frequently switching between applications. But I still do not have enough space to solve problems on the frontend part. This is a good excuse to replace my old 27" monitor with a new 34" one. At first I chose 34" at 3440x1440. But it showed too small elements on the screen, and scaling led to blurry fonts. Then I tried 34" at 2150x1080. It was terrible! You will be able to recognize every pixel effortlessly. It may be good for games or movies, but it's completely unsuitable for work. Finally, I got this 34WK95U-W monitor. Unfortunately, my iMac 27" (2016) does not support ultra wide resolution and all resolutions break. But I already ordered a Macbook 16 Pro M1, it definitely works with this monitor as it should. I expect it in a month, but for now I connected my iMac to the monitor with two cables (DisplayPort and HDMI), split the screen into two parts and work as with three monitors :) An interesting experience!

Great for work

I bought this monitor in April of 2020. Great monitor, great image quality.

About 10 days before the 1 year warranty was up, the displayport connector failed. 

Manufacturers have quality control down to a science. Always buy the longest warranty you can afford. Monitors and hard drives especially!


The WK models have a 1 year warranty, the BK models have a 3 year. I would have bought the BK but they sold out just before I was ready to make my purchase. Once the BK's were gone I ended up paying almost the same for the WK. 

I initiated my RMA just days before the 1 year mark from my date of purchase and so far LG has been excellent about honoring the warranty.

Good, but I wish I bought the BK model.

Love the monitor. It looks great. Amazing workflow. I don?t know if I have the colors setup perfectly on it, but it does feel a little cold in color. My biggest struggle has been burn-in. I work in music production/mixing/editing/Etc. so I may leave the same window up for hours. This monitor doesn?t do well with that. It leaves some phantom images of that up... I mean. It?s super subtle. You have to take like a dark ?Finder? window and hold it over the edges of the screen, but then you can tell it?s still ghosting you with some burn-in.


I really do love the monitor. It?s been extremely advantageous to my workflow, but this one issue annoys me to no end!

Great Screen, but it struggles with Burn-In

I had mine for about 2.5 years. It's input being all straight out of the back rather than straight down lead to the input jacks dying three times. Each time LG just barely covered the repair, and it took weeks to get back. Last week it suddenly died during usage, screen freezes and glitches out on all inputs, so I'm not sure if it's related to the inputs. While their panels are good and put to great use by other companies, their actual final product quality control and build are not good in my experience. After several different bad product quality experiences from LG like this monitor, I won't be buying LG anymore.

Great panel, typical LG quality control issues.

I purchased this with the intent to get 5K resolution with my brand new Dell XPS system. Despite having the proper build (Displayport 1.4 on the NVIDIA GeForce RTX 2060 SUPER 8GB GDDR6) and using the cable provided, the monitor continually warns me that I am not at the 5K resolution. I set the display to 5K and it also won't allow 60 hz refresh rate... again despite it being paired to a new XPS system with the proper build. I've consulted with LG and the degree of zero f's given were staggering. On the chance it was just one unfortunate person, I called 3x. They all read a script that basically said 'your system is incompatible' which is patently untrue and would not help me troubleshoot. I am able to change the display manually to 5K but lack of complete functionality for the price and sub par service make me think I will return it.

LG Support sucks, the monitor is okay

Very beautiful monitor. Great until the Thunderbolt port stopped working after 8 months.

Beautiful monitor that needs quality control.

I received this monitor Feb. 3rd 2021 and have had it for a few days.  I read through both the good and bad reviews. So far I haven't experienced any of the major issues.  I purchased an Apple Thunderbolt 3 cable just in case the LG supplied cable gave me issues. I will be returning the Apple Thunderbolt 3 cable.  I've purposely and repeatedly put my laptop to sleep for a few minutes and also left over night had haven't had issues with the LG screen not waking up in any case.

I downloaded the OnScreen Control App and was prompted to update the monitor's firm ware. Note that you may have to plug in the factory supplied USB-C to USB-A cable to complete the firmware update. Screen Split options are limited but do the job.

The monitor by default was in display port 1.2 when using the Thunderbolt 3 cable.  You'll have to use the option key when clicking on scale to get 5k2k resolution.

Things to keep in mind while using Thunderbolt 3 cable:
Display Port 1.2 - Allows DCI-P3 and 5k/2k but NO HDR 
Display Port 1.4 - Allows HDR but NO 5k/2k and NO DCI-P3

On to the reason why I didn't give it 5 stars.
The image retention (different than image burn) is REAL. I've only noticed it when I used a dark background after having a few lighter colored windows open. I did have to look for it and so far it hasn't been noticeable while editing on programs such as LightRoom. I will keep on eye on this to see if it gets any worse.

After only using this monitor for a few days, the 5k2k resolution and added real estate has definitely increased my productivity. The color accuracy in DCI-P3 is fantastic and great for editing both photos and video.

Works great with 2019 15" MacBook Pro -Radeon 560X

I am a diehard LG fan. I've had their phones for ages, I love their OLED displays, I trust their tech.  This however is the exception. This display suffers from massive temporary screen burn in issues.  The feature set makes it perfect for professionals, a dream display, but you'll be left with burnt in backgrounds and pretty much anything while you're trying to professionally edit a photo or whatever it may be.  Might as well work with dirty glasses on.

very disappointed in my investment

I had this monitor for over a year. When you finally set it up and it works (it can takes a while, it doesn't digest very well many drivers combinations)... The image quality is stunning!
However, LG released recently a fw update and since that moment, my PC doesn't charge anymore via the thunderbolt cable (I've a Spectre 13" x360 with 10th gen CPU)!!! I tried to change the cable, the port, whatever but it doesn't charge! Please allow us to revert the fw version!

Awesome image quality... When it works :(

Product required frequent reboots until it looked right. It finally broke with many lines of dead pixels after the 30 day return period. LG support could not figure out how to send return label. Gave up and begged retailer to return. They understood how terrible LG is too

Terrible product that barely worked until it didnt

This is the best monitor I have ever bought. 34 inches of all 5K sharp text and images. Cant go back to any other monitor..

Best Monitor ever!

I bought this monitor to expand my home office and the sheer size and pixel density of this monitor has been excellent. The screen is plenty bright for an indoor environment and the speakers are above average (though I still recommend using dedicated speakers). 

However, I've ran into numerous software issues trying to set up the monitor: mainly trying to get HDR turned on at full resolution through the thunderbolt 3 cable. It simply isn't an option when using the OSD and neither using HDMI or DisplayPort resolves this issue (strangely enough, displayport will show HDR at full resolution but only at 30hz). And when changing the settings on the OSD, the monitor will sometimes lockup and freeze, requiring a hard reset. FWIW, I'm running this on a 2018 MacBook Pro with a radeon pro 560x. 

Overall, I'm satisfied with the monitor but am disappointed that I am unable to use it fully as advertised. If HDR is important to you (whether as a content creator or just watching videos), I would suggest looking elsewhere.

Great hardware but buggy inputs/software

Product required frequent reboots until it looked right. It finally broke with many lines of dead pixels after the 30 day return period. LG support could not figure out how to send return label. Gave up and begged retailer to return. They understood how terrible LG is too.

I was able to get the full 5K/2K resolution using a mini Display Port to Display Port Adapter and the LG supplied Display Port Cable plugged into one of the Thunderbolt 2 Ports.  You need to press and hold the Option Key and click Scaled to display a dropdown of resolutions.  (see photo)  If you want to switch more easily, get the Display Menu App from the App Store to get a task bar icon and dropdown.  I have also run this at full resolution on my Linux Mint Workstation and Windows 10.  I bought it with the intention of eventually upgrading to a newer Thunderbolt 3 Mac.  My primary reason for the purchase was to have more screen real estate for web programming and development work. It really is a spectacular monitor.  (Oh and you must use cables rated for 5K)

Works on on Late 2013 MacBook Pro

Beautiful high resolution display that conveniently connects to my MacBook Pro 16" using a single Thunderbolt cable.

However, this monitor lacks ability to easily switch between two computers. I also have a PC connected using a DisplayPort + USB-B cables. In order to switch the display between computers, you have to first select the USB uplink in one submenu of settings and then select the input in another submenu. This process takes about a minute, which is 59 seconds too much.

I would suggest adding a configuration option to preselect pairs of video inputs and USB uplinks (e.g. Thunderbolt + USB+C vs DisplayPort + USB-B) and then using a single key press (such as currently unused cursor up, or cursor down) to alternate between these modes.

Awesome monitor

Actually a great screen. Perfect for image editing and it also works perfectly with MacBook Pro 2020. 
The finish is good. However, the Auto Brightness function does not work reliably. No matter what kind of device I connect to it. If the brightness is set to "Auto", the screen changes its brightness from light to dark to light to dark within seconds. I sent the screen in with the result that it came back after one week with the diagnosis: "Works fine". Not at all. You pay so much money for a top screen and then not all functions work. A pity. If there was a comparable alternative I would change.

Great Monitor, but...

There are little options when dealing with a monitor with the following specs: 
1. Thunderbolt-3 with power output enough to charge a MacBook Pro 16 inch full power. 
2. Speakers. 
3. Light ambiance sensor. 
4. 5K2K display (even the other options out there from other manufactures use LG's panel)
5. Compatible with macOS. 
6. Business looking stand.
7. Not curved (image does not seem distorted)
8. Modern-looking edges and frame.

Overall, even though it sometimes freezes when macOS goes into sleep, there isn't really much out there to compare it to. Best in its own class.

Unique monitor!

Everything this monitor does...it does very well. I can't imagine going back to the office after Covid with out it. It made a huge impact on my productivity.
