Anyone who owns an LG smart TV must inform all guests and family members that they are being monitored – this is required by LG’s current terms of use. Meanwhile, LG monitors install potential malware and surveillance software on a connected Windows computer.
Old monitors need it for absolutely nothing, like my 2020 LG. Every feature works out of the box, because it has to over display cables.
I think at most it adds an ICC profile, but it’s not matched to the panel anyway and you can just install that seperately.
