This is somewhat perplexing. On Apple's product page for this monitor, it states:
>For optimal performance on the 16-inch MacBook Pro, connect to power using the MacBook Pro's 96W adapter.
However, the LG product page for this specific model states that the monitor can deliver 94W over USB-C. (And indeed, many news stories mentioned that fact when the revised monitor came out this summer.) For reference, the previous version of this LG monitor could deliver 85W while the power adapter for the 15" MBP was 87W, but that didn't apparently cause any problems.
