Down The Tech Rabbit Hole...

I have a 27” monitor that was given to me a few month ago that I finally want to put use. I want to use it in 3 different ways: 1 - Connected to the DSLR that’s mounted overhead on my rig so I can see what the camera sees while I record myself drawing. 2 - To watch movies & shows via a streaming device. 3 - A monitor for a Raspberry Pi computer running a retro video game emulator as well as regular computer capabilities. I thought it’d be a simple task but the monitor only has one HDMI port and no speakers or audio-out ports. I haven’t tried connecting my camera because I need a mini-HDMI to HDMI cable, which I don’t have. I connected my Raspberry Pi but needed speakers so I went to the store and bought a set. When I came back I played a couple games for a while after connecting the speakers to the computer. Afterwards I swapped the Pi for an old Roku Streaming Stick but gave up when I realized there’s no way of getting audio from it without buying a separate piece of hardware. So now I’m looking at HDMI switches that also export audio to get it all to work. The shit never ends.
