is magnetic speaker shielding a thing with non crt monitors?

[inquisitor1]

back in the crt days everyone always talked about "shielding"

is it still a worry with lcd/led monitors?

It doesnt hurt if its shielded but is there any danger if they arent?:

i don’t think LED panels are affected CRTs were " beaming" the image on the screen so magnets would mess up the beam

Never seen a flatscreen getting any image distortion from speakers (or other magnets). Most likely the reason is what is already said on the post above.

No.

The only objects that could be damaged are, in order of disappearance: audio tape reels, ZIP disks, floppy disks, audio and video cassettes and recorders, analog oscilloscopes, magnetic compasses, credit cards with magnetic strip and LTO tapes.

Magnetometers (electronic compasses) in phones might suffer too, I'd avoid strong magnets nearby.

HDDs seem to be very resilient, people have tried to place magnets directly on them, and the data remained intact.

Even CRTs are not that delicate. On a very old colour TV, I placed a speaker magnet directly on the screen. That caused very strong colour and geometric distortion, and some of it remained after I removed the magnet. But it all disappeared next time it was power on, because colour CRTs always had degaussing coils (which could damage audio cassettes, ha).

nope, it does not afect no crts, crts work with a electron beam that scans the screen to form the image using magnetic fiields, that´s why speakers had to be shielded to be close to a crt, or it would distort or magnetise the screen

Stick a magnet on the screen directly, could be an issue, TN panel would probably end with dead pixels in the exact shape of the magnet (lets say round).
