Yep, I tried Continuum (950XL) with my LG PV150G Pico Projector.
The good news is that it works flawlessly with the Continuum Dock+HDMI cable; I already used it multiple times, both for presentations and working with files/office, it's a great option when you haven't a screen at hand; for video/images it's quite good, for excel files and docs/reading is fine but the bright spot is within 25-40'' sized projections, smaller than that and you have problem to read the lines, bigger and it becomes too fuzzy (light environment is also another determining factor).
The bad news is that I haven't been able to make it work through Miracast. It just doesn't connect, the 950XL sees the PV150G but when trying to connect it just fails.. it seems a problem related to the LG model though, given I have been able to connect my 950XL through Miracast with my old PV3000 adapted without issues.
