I owned a Microsoft Surface Go which have an USB-Type-C USB port. Since now I used USB-ports just for periphals and also have a USB-graphic Adapter for an older Notebook.
There exist some cables USB-C to DP or HDMI. So can I just connect my Surface via USB to a Monitor? I don't Need an extra graphic Adapter than before? Or has it to be a special USB-C port to support Monitors?
Sorry for this newbie Question, but before I buy this (expensive) cable I just want to make sure that this will work.
Type-C port can be a multifunctional port if it is designed so. A standard Type-C port was introduced as "USB only", and all other "alternative" uses of this connector are optional.
To some surprise, the basic MANDATORY function of a Type-C port is USB 2.0 functionality, see section 5.1 of USB Type-C specifications Rev.1.3. So technically one shouldn't expect even USB 3.0 functionality over a arbitrary Type-C port, and definitely not any more sophisticated alternatives as DisplayPort or PowerDelivery.
However, per most recent USB Type-C specifications, all alternate modes require the use of a subset of PowerDelivery protocol, so-called "Structured VDMs", to mutually identify "link partner" capabilities.
There do exist Type-C to DP cables, but they won't function unless the host port supports this "alternate" functionality. If no alternate mode supported, you will still need your old USB-graphics Adapter.
