It's written right there in the display's manual the image retention is "normal" and they suggest using a screen saver... not sure what you expect. Don't worry about it unless it's seriously affecting your usability of the display.
you do not understand the problem if you think this ^ is the solution. Burn in should not occur from watching a 1 minute video on youtube, and yet this causes the entire safari webpage itself to burn into the screen. That article is anticipating that the user is leaving these windows open for 15, 30+ minutes, not 1 minute.......
I got a new screen from them which developed the same problem so I sold it and bought a ASUS PB287. The colors are not as good but I can leave the same image on it for days if I want to and it wont burn in.Did you ever resolve this with LG? I have this problem as well.
I have the exact same problem with my LG UltraFine 5K. I realize that some retention is normal for this kind of monitor but IMO it is unacceptable for a >$1k monitor to show the retention my monitor has and what you describe. Today I have send my monitor back for repair. Hopefully they will also judge that this is unacceptable and send me a new one.
This monitor is really one of my worst buys ever. A wobbly piece of cheap plastic with horrible sound for a premium price. (The image quality is great though if it wasn't for the image retention).
I purchased the new LG 5K display in 2017 with my new Macbook Pro 15". I remember Apple had removed them for sale for a short period with the whole shielding issue. I waited to make sure I was getting one of the brand new models with new model number that had no issues. Before I ordered it I called the Apple store online to double check and verify that they had resolved all the issues. I then paid to have the display shipped to me in Ecuador, and paid crazy shipping costs plus our ridiculous importation taxes due to the price of the display. So I have about $2,000 invested in my display and after about a month or so I noticed the image retention problem. It is more noticeable when switching between browser windows with a white background but you can clearly read text from the other workspace when you switch from one to the other. I called Apple and the first thing they said is that they don't warranty it. Then LG basically told me I was out of luck in another country, unless you purchase it in that country. Since it is not sold and there are no Apple stores official in Ecuador, I guess that means I get screwed with this purchase. My Macbook Pro was nearly $3,800 with the upgrades and it too had issues running the display. When I would render video in Final Cut Pro X the computer would heat up and the screen would start going crazy and flickering and I would have to unplug it and wait about 10 minutes for it to get back to normal. This would also happen if I did anything on the computer that would strain the CPU/GPU. I loaded a game just to test and it had the same problems. Basically, I could not use the display without unplugging for rendering. The update 10.14.4 was released not too long ago and it actually did fix my problem. The display and computer are working correctly now. This purchase with accessories was nearly $6,000 after import charges and I have to say this has left me with a very negative opinion of Apple. I use to want the latest and the greatest but from now on I will keep my hardware until I am forced to replace it. The value drops so much every few months and then now Apple is discontinuing the sales of the 5K display to replace it with an Apple branded one. It really makes me feel they only care about profits and not customer service or experience. How crazy is it to charge someone for premium equipment like this and leave them with broken, flickering, ghosting, overheating computers and monitors. What a shame that a trillion dollar company cannot do any better than this.
It's not Apple who made this display, it's LG.
It's also well known that LG have issue with their display for image retention, and tint shift across the panels.
We have a history all over since retina Macbook Pro, and iMac... All exhibit the same issue.
I did the test for 5min at maximum brightness and I didn't see any ghosting. I have a 703 monitor.
EDIT:
Updating this post. After owning the monitor for 3 years, I'm now seeing image retention that I didn't see originally. It's quite bad, showing image retention after a minute or so on normal brightness.
I am seeing the same image retention issue on my LG 5K after owning it for 2 years. Image retention seems to be happening only close to the left edge of the screen. But it is pretty bad and it happens SO quick!
Is there anything we can do to have them fixed? warranty is out I guess.
They used to fix them for $150 flat - since March this year they are refusing to do so. Depending on date of purchase there may be some state consumer laws (in the US) that may come in place. In California there are laws that prevent warranties from expiring or running if there is a known defect that is not corrected. (For that defect) The shielding issue on the first batch is clearly known to LG. There were multiple reports and a statement on it. The problem is anyone at LG other than the outsourced call center are unreachable. They do not respond. They do not want to address the problems. They blamer it all on COVID. I hope this could be brought up to Apple. The reason an LG call center gave as a reason not to repair is that this is an Apple product only.
Some people say that this is a normal behaviour of ISP panels, maybe this happens too all LG 5k panels. If so, it doesn't makes sense to change the display. Therefore, please, if you are a owner of this panel, try this test for 5 minutes an show us the results.
Thanks
Apple has a page on this, and they claim if you follow their steps, you can remove the image retention. It didn't work for me, so I ended up replacing the panel at my own expense. Unless you are a trained computer technician, don't attempt it yourself with the iMac. It will end up costing you about $500 - $600 parts and labor included if you use a third-party repair shop. Try to find the one authorized by Apple.do you guys know what the fix involves? Replacing the lcd panel? Backlighting?
what kind of repair shop would fix this?
thank you!
You are not being unlucky. The problem has existed for years. If you are still running macOS in "light mode" you may not notice the image retention even if it's there. But, switch to "dark mode" and move an application with a dark background over an area where the macOS dock is (after hiding the dock), and you will see the dock behind the dark-background application even though the dock is not there. That's a burned-in image. You may also see some web pages burned in to the screen if you left a static web page on the screen overnight and the screen didn't turn off on its own. The web page would be somewhere on the screen when you move a dark-background application over it.It's very confusing to me because I don't think I am just getting unlucky, I think there must be something else going on here.
I've had 3 of the iiyama 27" 5K monitors (that use the LG panel) for approximately a year. All of them can get a bit of short-term image retention if a constrasty static image is displayed for a while, but that goes away pretty quick. Thankfully none of them have any permanent image retention.I also purchased a 5K monitor with the same LG 27" 5K panel, and I have been very careful with this monitor. I babied it, I turned it off every time I would leave my desk, etc. After 3 months of using it, I noticed an image retention at the bottom of the screen where the macOS dock is. Obviously, the dock is a static image that's displayed most of the time (unless you are in full screen). So, 3 months of very casual (less than 2 hours per day on average) use of the monitor resulted in the image retention.
My Color Settings > Picture Mode is set to DICP3. There is not much I can control in that mode. My brightness is set to 35% and contrast is set to 50%. Saturation is also set to 50%. I can't find any R/G/B "channel intensity" settings at all in my menu.I've had 3 of the iiyama 27" 5K monitors (that use the LG panel) for approximately a year.

I remember that when playing around with their On-Screen-Display button settings to get them to look the same, if "Color" was set to "User Color" and R/G/B each cranked to 100%, the image retention was suddenly much quicker and more obvious.
Presumably this level of "hardware" tweaking is not user-accessible on the LG Ultrafine / iMac, so maybe calibration at the factory feels the need to set these R/G/B "channel intensity" values (or whatever they are) differently for each unit, hence making some units more susceptible to image retention than others.
