If the connection runs through a cable or adapter that converts a mini display port to DVI or HDMI, the adapter must be a Passive Type-2 or Active adapter for it to support resolutions above 1920 x 1200 dpi. Passive Type-1 adapters don't support resolutions of 1920 x 1200, and most Passive adapters are not Type-2. Additionally, some Active adapters note in their documentation that they only support 1920 x 1200 resolution, so you must buy a 4K high resolution–compatible one if you want to use a resolution above 1920 x 1200 dpi. Customers must verify the maximum resolution supported by the adapter they are using.
Before the Surface Dock April 2016 firmware update, some Passive Type-1 and Active adapters allowed higher resolutions because the Surface Dock displayport firmware was incorrectly allowing it.
