Using a Raspberry Pi to add a second HDMI port to a laptop

For what it’s worth, I can’t get any adapters to work on my ThinkPad and haven’t been able to resolve it for a long time. My only HDMI port is broken.

I’m going to try this with one of the Pi’s I have laying around. I’m excited to see if I can get it to work!

I'm excited as well to see if you can get it to work!

Since you mention Thinkpad, here is a personal pet peeve.

A company called StarTech makes ExpressCard devices and USB devices. They make:

* An ExpressCard HDMI capture device (no longer manufactured) that sits flush with the body of the Thinkpad. [0]

* ExpressCard USB3 peripherals that adds one or two USB ports to the Thinkpad and sits flush with the body of the Thinkpad. [1]

* USB3 to HDMI output devices that leave an unsightly dongle protruding from the Thinkpad. [2]

So, what StarTech does not make (and my pet peeve):

An ExpressCard device that adds an HDMI output port to a laptop and sits flush with the laptop's body.

Note that such a product would seem to be a trivial combination of their existing products. I would also expect that such a device would be cheaper to manufacture than the equivalent capture device.
