I went into an Apple Store and noticed on one iMac and both LG Ultrafine 4k and 5k displays, there was dust build up on the LCD panels. looked very similar.
If you design notebook dust filters that cost 600$ to replace you deserve every class action lawsuit and more...
There is a gap inside the display between the backlight and pixel layer, this is typically where the dust spots happen, and Apple's display supplier (LG) does a terrible job sealing these displays.Also - I can understand dust getting into the computer, but with these displays being laminated to the glass, is there even an air gap that the dust could get in to settle? Unless its a fault with the lamination?
Honestly, haven't ever had a problem with a Lenovo overheating or needing to replace the filters, I only opened them up to upgrade the hard drives to SSDs and add RAM. They also have channels and drain holes for liquid to escape from the casing if something gets spilled on it, doesn't completely prevent liquid damage, but dramatically reduces the risk of it, especially if you immediately power down, remove the battery and let it completely dry out before turning it back on.Is it in any way helpful? I'd expect them to get plugged and need cleaning/replacement and end up being just one more thing to deal with.
Actually, the devices should be designed to work in an average environment, what you have is not an average environment, it is a step away from a clean room. The reality is you shouldn't have to take this step to make things work properly.As a owner of a $3500 2017 iMac, I didn’t expect or demand Apple made sure my office was cleaner than normal. I purchased a large Honeywell Hepa filter air purifier. No problems thus far with dust etc.
I take mine to authorized service centers because of this and because I can usually get my system back the same or next day at the latest.And this is exactly why I am afraid to take my iMac in for repairs—even if they do resolve this screen problem...what new problem may be created or set off by technician handling? Not to mention not having my computer and having to wipe the hard drive to protect all of my data.
ironically they need a dust gate.
I’ve seen this happen to many iMacs I’ve had at the office. Didn’t realize it was dust.
I have that issue on my late 2012 iMac on both the bottom left and right corners. It‘s taking up a pretty big area and is especially visible on light backgrounds. I have no idea if Apple would do anything about it, especially since I‘m not in the US. Probably not, so I just learned to live with it.
think of what the humidifier is doing to your lungs?My humidifier destroyed the insides of my iMac with white powder...
I’m amazed by how many comments there are assuming that these Macs must be in filthy environments.
The hand few I’ve seen this happen to are in extremely clean office environments. One of them is even in a sterile medical procedure room.

This is exactly what happened to my iMac. So much gunk got sucked into the thing that it looked like a water stain covering 1/3 of the screen.
Couple that with the internals cooking the screen to a sickly yellow color due to Apple's inability to comprehend proper thermal management, and I was turned off from all iMacs after that.
Between the glass and the LCD display.The screens are glued and there is no glass on my screen, so where is this dust getting trapped? I'd like to add that this hasn't happened to my screen and I've worked on building sites a number of times.
