I wanted to be able to hook my Surface Pro 3 to my current PC's graphics card and extend the PC's display. I see the Surface Pro 3's resolution is 2160 x 1440. When I look at mini displayport adapters, nearly all of them have a max resolution of around 1920 x 1200. Could anyone tell me what kind I would need to utilize Surface Pro 3's full resolution as an extended display to my current PC? Thanks for any help.
