Use displayport for fast data transfer
As others have said, DisplayPort is essentially one way. Your GPU can send data to your monitor, but your monitor can't exactly send data back to your GPU(1). It isn't made to receive. Even if it could, I'm not sure DisplayPort was ever designed for duplex operation, so you'd most likely halve the bandwidth or more if you wanted to be able to go both directions.
Network protocols also include stuff like routing, which is lacking from DisplayPort, so it would be strictly a 1:1 connection. Oh, and the maximum cable length for DisplayPort is very limited, compared to network cables (2 meters vs 100 meters for Cat 7).
Last but not least, I'm not sure how efficient it would be to encode your data into an "image", send it over DP, then decode that image back into data, instead of using protocols that are made to send data in the first place.
Of course, cables are cables and don't care what information it sent over them. So you could use the physical connection and use a different protocol. But once you do use something like TCP/IP, you'll probably lose quite a bit of that bandwidth that comes from using a simple one-way only protocol.
1) Just to be clear, your monitor can actually send some data back to your GPU (e.g. information about monitor model etc.) but that's an auxiliary channel with much lower bandwidth.
