Okay so I just got an HDMI cable to hook up my smartphone to my TV and was just considering the possibilities. So I was wondering if there was a way to use the HDMI cable to display my PC desktop. I know it should be technically possible, my phone has a screen that could be the output. But it may require some creative hacking. This is more just for fun than out of need, but I could see some practical applications, such as testing a new PC build when a monitor is unavailable, or would require extra set up. Any ideas?
