Just as the headline states, I'm still not clear on resolutions for the dock. I have a old HD ready TV (yes, its 720p). Will the dock work on lesser then 1080p? I know for a fact my old Surface RT wouldn't. My tv can go 1080i, but somehow the Surface RT won't recognize that. So how much legacy will work here? (And no, I don't have money to just go buy a new TV, in fact I shouldn't really buy the Lumia 950 XL in the first place), but I dropped my 1520 hard and need a new phone :-(.
