[SOLVED] Could you turn an HDMI port to a PCIe port for input?

[joshua123033]

This idea was created because the HDMI port has lots of GBps and also has PCIe lanes for low latency. So could you turn that HDMI port to a PCIe port for something like a Graphics Card to connect to?

The question is, could 'who'?

Us out here, with hardware not designed for it? No.

Could a motherboard be created with an HDMI shaped port, to accept something from a GPU? Maybe, probably. Given that Thunderbolt can mostly already do this with eGPUs, there is nothing special about the HDMI port that would cause manufacturers to go down that path.

Thanks for answering. I guess I hadn't thought the practicality of this idea through.

As a side question, how would you change the HDMI port to become a PCIe port (like Thunderbolt)? (if it is possible) Then you could use something like this: http://www.hwtools.net/Adapter/PE4C V2.1.html to turn that HDMI into a PCIe slot.

That things seems to just use a PCIe port to interrface with HDMI.
It does nothing for an existing HDMI, trying to accept a signal coming IN.
