    Getting ready to return my LG Ultrafine 4K, which is super disappointing because overall I love this monitor. But I have discovered that images are ghosting on the screen, and this seems like a precursor to burn. And I’m not talking about ghosting for a micro-second, but minutes. And this is troubling since I like to have my folders visable on my desktop, and my wife has her dock up all the time. I’ve attached a few photos. This is on a 2015 Macbook.

    Anyone else see a similar issue?

    Noticed similar ghosting when using Apple's Flurry Screensaver. Concerning. Going to keep my eye on this as well Luckily Apple have extended their return policy to Jan. 8 for the holidays.

    Apple's Flurry screensaver is notorious for causing odd screen anomalies. No idea why.

    Quick update: I returned the screen to Apple. The ghosting was getting worse, and I started seeing artifacts from the previous day on the next morning when I plugged in the laptop. I suspect that this is a wider spread problem, but won't be as noticeable to users unless they use one flat color instead of an image for the desktop wallpaper.

    LG monitor is "famous" on this burn-in problem. (including smartphones)

    That's why people are trying to get Macbook Pro with Samsung panels. I remember it was even worse for MB 2012.

    I was about to order the MBP 13" / LG 4k combo. But after reading this I'm concerned as I've had image retention issues on my 2012 MBP also. Could you guys do this IR test and post your findings / photo's to get an idea of the severity of the problem? Tnx!

    Wish I knew about that test page before I returned it. I would have loved to have that data. I hope that someone else can post an image, and prove the issue is more widespread than just the monitor I got. If I just got a bad unit and others are good, i would GLADLY go buy another one. I loved everything about that monitor except the IR issues.

    I tried this today out of curiosity. Did the full 10 minutes, and when it reverted to grey I could see no evidence of the black and white grid left. So no issues with my screen.

    This is very encouraging! Let me ask you another question, when you go into your display preferences, do you have the option to have the monitor automatically dim? The other issue with my LG 4K display was that it did not detect the light sensor, so all brightness adjustments had to be manual. Maybe I just got a dud. Might have to give another one a try!

    Yep. My work 4K LG Ultrafine has really bad ghosting. Doing that test showed the grid up very visibly for several minutes :S. Was thinking about getting one of these for myself too... but probably not now.

    Just wanted to let you know I pulled the trigger on the LG 4k MBP 13" combo about a month ago. This screen is fantastic. Zero ghosting! Couldn't be happier... love it!

    I have just started seeing this on one of my two 4k monitors, the one in my home office. I will check at work tomorrow on the other one.

    It is the first time I have noticed it and Googleing brought me here.

    It is _reall_ bad though. Very strong ghosting. It is even apparent on the stock Apple wallpapers (so not only on uniformly coloured areas).


    I just checked my identical 4k unit at work and it doesn't have the ghosting. This is not really normal... Did anyone go back to Apple with this?

    Update 2:

    Since I had 1 unit with ghosting and one without, I got in touch with the Apple store that ole me both units. They referred me to LG Canada (the units were bought in that country).

    LG Canada refused to help me because the unit featured a 'US' serial number.

    LG US refused to help me because the unit was sold to me by Apple in Canada.

    The entire situation was entirely ridiculous given that these units are most likely completely identical all over the world.

    After countless hours on the phone with Apple, LG US and LG CA a helpful Apple store supervisor finally saw the absurdity of the situation and decided to exceptionally allow an in store exchange. The new unit seems perfectly fine.

    What a story... buyer beware. LG has terrible support.

    One of mine seems to have an issue with this. Will probably take it back at some point.
