Seems to be working OK in my X-E3 so far. If you choose large displays, you loose some items like the distance scale in MF. There is only so much room for display data so don't be surprised if you don't see everything you want. Personally, I left my VF display items small and only changed my LCD to large. I only use my LCD for image viewing anyway; rarely for shooting. Haven't tried editing with the X-RAW Studio120 yet.
