According to a series of tweets by @dylandkt, they suggest that LG could actually be working on three new monitors for Apple. Two of these monitors are apparently designed to share similar specifications as Apple’s new 24-inch iMac and the upcoming rumored 27-inch iMac Pro, while the third will be the successor to the 32-inch Pro Display XDR that will sport Apple branding.

However, the third model is rather interesting because the tweet claims that there are references to a custom silicon that could be used to power the display. We’re not sure what the chipset could be used for and what kind of advantage it might have over a display that doesn’t have a chipset, but we’ll have to wait and see.
Note that this is only for the 32-inch model and that the other models will not have a custom chipset and will be more traditional displays. Either way, take it with a grain of salt for now and hopefully we’ll have more details come 2022 which is when Apple is presumably going to announce them.
