Active vs Passive Mini DisplayPort to HDMI adapter

When looking for an adapter to convert from Mini DisplayPort to HDMI for your Surface devices, you must know the difference between passive and active adapters.

Many users experience problems when they try to connect dual external displays to their Surface Dock. The main reason is that the Surface Dock doesn’t support dual-mode Display (DP++). The DP++ can dynamically convert the signal from Mini DisplayPort to HDMI. So, the Surface Dock needs an active adapter with a particular signal conversion chip.

Generally, an active adapter is more expensive than a passive adapter. However, if you have a Surface Dock or plan to get one to connect to two additional monitors, then the active adapter will be your only choice. Here are the best active adapters that allow your Surface devices to output a full 4K display with audio support.
