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

The MFR date is located behind the stand. You have to disconnect it to get access. The serial number is also there.

Hi Joel

Now your shift pixel is resolved or not ?

Well, at least you did not have to bite the bullet and pay for another monitor...

Amazon is pretty good to deal with...

LG crap hardware or otherwise, I bought mine through the Apple Store. It has an Apple logo on the box!

Yet Apple won't take any responsibility for it whatsoever.

I’m another having this issue. You guys that are using the USB-C cable, are you using it in the thunderbolt port on the monitor or one of the USB-C ports on the monitor?

I bought the Apple thunderbolt cable and it made no difference with the issue.

I did the same thing...still using it....however, the problem had not appeared for a long time....I do not shut the computer off...

Now, all seems stable....all too weird...

Incorrect. 5K only supported using TB cable connected to TB port on the monitor. even with latest monitor.

I have a MBA M1 with the LG monitor and using the TB cable and so far no issues. I'm running Big Sur 11.5.2.

Apple already pulled the monitor from their stores in all European countries and most Asian countries....you know regions where they frequently get sued! LG discontinued this model btw. I do not expect this to get fixed to be honest. There are too few of us with this set up for them to care.

Yeah, that’s definitely not a solution lol.

Posted the below on the other thread involving this issue ([Mac mini] - M1 Mini issue with LG 27" 5K Monitor) as a reply to earns helpful tip.

Thanks, I shall set up a hot corner then.

Seems like companies are getting away with their products not working the way they’re expected to more these days though. You would think Apple, as detailed and customer oriented as they, are would at least care enough to try and address the issue. The monitor is still being sold on their site…with this annoyance not appearing as a known issue. Thought I was getting a bad arse 5k monitor, instead I got a bad arse monitor that occasionally annoys me.

I found that if I put the computer to sleep and then wake it up the problem goes away for a number of days.

Also, does anyone have problems with the power cord? It does not fit the receptacle well and if I adjust the monitor it loses its connection. Has anyone else had this issue? Has anyone requested a replacement power cord from LG? I have substituted the power cord with a different one .... it helps but the power connection is still lost at times. I avoid moving the monitor now. This should not be an issue.

The vertical shift is not a deal breaker because I can remedy it in a few seconds. However, the loose power cord in the receptacle was a pain in the rear....however, I substituted another similar power cord I had and the fit was much tighter. I was going to swap at the vendor for another unit but they where out and did not know when more where coming in. So, I resolved the power cord issue on my own and I can deal with the shift within a few seconds. Overall the new MacMini M1 and the LG screen is super clear, which I needed, and there have not been any other issues.
