How to tell if an LG 5K display has had the shielding fix applied?

    Hey everyone,

    After LG made the statement that all displays made "after February" would contain the shielding fix and Apple pulled all sales until it was fixed, I ordered a 5K display — which shipped yesterday and arrived today.

    Unfortunately, my display has a manufacture date of January 2017. D'oh!

    I work with WiFi equipment for a living and, obviously, a display susceptible to interference from WiFi equipment won't cut it. So, if this hasn't been fixed, I'll return it right away.

    However, if the display has had the fix applied, no big deal — and there's no need to return a display that won't have the problem.

    So, does anyone know how to definitively tell if the display has had the additional shielding applied? I've attached a photo of my display's info panel, which is situated behind the stand attachment plate. I notice the round black sticker on the top right — perhaps that's the indicator?

    Well, here's a shot of mine. I hope this helps in some way. I received it last Tuesday (February 28, 2017). It's going back though. The left side of the screen has a pink hue to it while the right side has a darker green hue.

    I noticed my dates are written a tad differently and also I have a square, while yours is a circle sticker in the upper right next to where the S/N is located.

    Someone in a different forum stated S/N with 702 + have the additional shielding.

    I swapped my 5k for the 4k. I'm a bit more satisfied with this as the pink/green hues are less obvious on white backgrounds. Save myself about half a grand too.

    I don't think there's any way to know for sure. Try testing with a router.

    If you ordered it after the Apple.com lead times went to 6-8 weeks (or whatever it was) and then down again (which it appears you did), you should have a shielded model.

    I believe I bought mine when it was 6-8 weeks and I believe I got a non shielded version. I did an exchange and should be getting a replacement tomorrow. Hopefully it's shielded.

    I spoke to LG customer support and was told that there's no external way to tell if a pre-February unit has had the additional shielding installed. He advised me to return it and try to get a newer one, which I shall.

    Thanks for the followup. I have an older Ultrafine 5k that just arrived. The screen is significantly better in terms of pink/green hues. My other 5k I shared had pink to the left and green/dark to the right from the center screen. This one is fairly uniform and bearable; there's only a pink strip about 3-4 in from the left side and the transition is subtle. It's also an older model from December 2016. I set my MBP under it on the stand and and also my router behind it and nothing happened. So I'm assuming this one is shielded. If not, just glad to at least get a reasonable screen.

    I think LG dropped the ball here by not adding some kind of external symbol to signify that it has shielding.
