If I’m on the go, I’ll hook up my laptop to the TV with an HDMI cable, set the TV as a duplicate screen so I can close the lid on my laptop (make sure closing the lid doesn’t lock your computer or put it to sleep), then use my wireless mouse and keyboard so I can sit on the couch/bed/whatever and control it from afar.
At home, I bought a micro PC that I keep connected to the TV via HDMI. Then I use a wireless mouse/keyboard to control it from the couch.
The micro PC has WiFi so I can connect it to the Internet, and all devices on my home network can see each other, so I can quickly copy something from my regular PC or laptop to the micro PC if I want to view it on the TV.
I mostly use the micro PC for my streaming services. I don’t trust my Smart TV to be connected to the Internet, so I don’t use any of its apps. But I’m old; I’m used to TVs being dumb devices. I don’t like handing over control of my apps to companies; I’d rather access them directly from a computer.
We are. I just read an article yesterday about how Microsoft paid research publishers so they could use the papers to train AI, with or without the consent of the papers’ authors. The publishers also reduced the peer review window so they could publish papers faster and get more money from Microsoft. So… expect AI to be trained on a lot of sloppy, poorly-reviewed research papers because of corporate greed.
