Can confirm: I've got one monitor (ASUS, TN panel, can't recall the name but it was probably from '12 or so) that displays a severely over-green signal when connected up to an O2. It's the monitor itself not entirely understanding what the O2's video output is trying to do; luckily, LCD monitors that do work with the setup aren't particularly rare or valuable.

I keep forgetting to jot down the part numbers of the ones I have that do work. Hmm.
