LG Ultrafine 5K M1 Mac spurious vertical shift in a 2 inch band on screen

Kinda wished I had read these 8 pages of posts before I spent big on the mac mini/LG Ultrafine5K.

Pretty disappointed to say the least.

Thank you to all who have posted workaround "solutions" for this issue and here's hoping Apple will figure out a fix for this problem.

Over to you Apple!

I know the feeling.

Apple should at least share this known issue on the display description to inform potential buyers. Or make a statement ensuring owners and potential owners a solution is in the works. If there is no actual solution, then they aught to make it right. I have a feeling owners of these displays are heavily invested into the Apple ecosystem.

Yep....it is still there....oh well...I have a replacement coming in a few days....it is a swap with B & H Photo. I really like the monitor and its connections to my MacMini...what is the opinion?....is it a computer glitch or the monitor?

Where do you find the manufacture date? I looked on the sticker on the box and it is not there.

So...know one really knows what is causing it...MacMini or the monitor....I really thought is was the cable but no it was not.

I bought this one at B&H which has a liberal return policy for 30 days. They where out of stock when I wanted to replace it. I ordered another one for when they are in stock...maybe it is a batch issue?

Thanks, I will let the swapped monitor come in....I will check the man. date...

If it still occurs then I will have to put up with it...it seems not to occur when the mini goes to sleep on its own...that is just a guess...

Actually, no one really knows if it is the monitor, mini or the cables...

I really like the monitor....I probably will just put up with it...if it really becomes a pain I will just get another 5K brand of monitor ... but if we really do not know for sure if it is the monitor or the computer we are really working blind on this...

thanks for the info...appreciate it...

I agree with you on all points .... even though I bought the monitor through B&H because they have what is called a PayBoo card and they pay the sales tax and as long as you pay the balance off when do there is no service charge.

I decided that I will wait for the 2nd one from B&H and live with the issue because the I like the monitor.

I bought the Mac mini through Apple. I actually find it irritating that most of the Apple stores do not stock the computers anymore....at least in my area....my "s in l" waited over two weeks for her 27" iMac a few months ago shipped from Ireland...

My mini was shipped from China....at this point there appears to be no solution. I will swap my monitor with B&H because of another problem. The power cord has a poor contact with the receptacle...If I adjust the monitor I have to fuss with it to get a good connection. It could be the power cord...I may try a different one if I have the same issue with the replacement...

After I get the replacement I will be back to update

Yes, using the two F-keys for brightness control, I can control the monitor brightness (with the USB-C cable). My keyboard is a Logitech K811. As for the power cord, mine appears to be solid. The end where the cord meets the back of the monitor is tight. I wiggled it but the monitor did not lose power.

Hi Joel

Did LG supply any details of the repair they undertook?

If you setup a hot corner for putting the monitor to sleep and try it a few times (3-5 attempts normally generates the misalignment), has their repair genuinely resolved this?

Update: Not Fixed. Well ... I'm sorry for the red herring. After getting the monitor back from LG, the issue didn't crop up for a couple of weeks. However, yesterday the pixel shift was there again after a wake-from-sleep.

It happened again this morning. So, I was incorrect, sending the monitor off to LG for repair did nothing to fix the issue.

It did not resolve the issue. I thought it was fixed because the problem didn't crop up for a couple of weeks after getting the monitor back from LG repair. However, the pixel shift cropped up yesterday and again this morning.

I've tried both the Thunderbolt cable that came with the monitor. I've also tried this Anker Thunderbolt cable. The pixel shift issue happens with both cables.

Sending the monitor to LG for repair failed to fix the issue. I'm seeing the pixel shift again.

I have no idea what they did to the monitor. When I called to check on the repair status, they told me the technician was waiting on parts. However, I'm starting to question that they did much of anything.

Thanks for all your answers guys !

I desperate really !

Today, i return my mac mini M1 and i have the choice to return the monitor too. So i really hesitate. As i am a designer, i can’t work with this pixel shift even if it’s random…waiting maybe the day Apple will correct this bug or sell a new monitor less expensive than the XDR (sorry for my poor english :)

Best

I bought an extended warranty from B and H....at least I think I am covered...a major mistake on Apple's part for partnering with LG...plenty of other dedicated monitor makers out there....too bad there are not too many 5K monitors available yet...

I have had a lot of trouble with the power cord being too loose in the receptacle...I just replaced it with another one I had....the difference is that the supplied LG power plug is slightly small than you would pickup on Amazon or a similar vendor. Again, I really expected top of the line hardware with the monitor and I was disappointed with the body of the monitor and also, of course, the power cord for the price of the monitor. The display is great so far but there really is no excuse for these issues.

Same issue here. I had a bad run with LG 10 years ago and vowed never to back their brand. But this display being the "ideal" offering for my M1 mini setup, meant I caved. I figured they have surely improved over a decade of development... 1 week old $1900 display. Problems out of the box. I will replace this display as many times as I need to at the cost to LG until a better offering is presented to me. Even if it means ACCC refund in 2 years allowing me to move to another brand.

I hope you're right, but several times now, people on this thread have claimed "x" solved the problem only to find out several days or weeks later that "x" did not solve the problem. Since 11.5 is only one day old, I'd say it's a little early to tell if 11.5 contains a fix for this issue.
