The B650 series are already mixed with S, A, and C panels. Not sure about the 22" but you can go check in the store by looking at the right side for the sticker. Then look at the version number. If the first letter starts with C, then it's CMO, if A then it's AUO, and S being a Samsung panel. But just because one set has for example CMO doesn't mean that all of the same sized are all CMO.
