This is my external portable monitor that I usually take with me for my computer. It gets power and video from one USB C cable it works with any computer that can do video over USB-C. It also works with my iPhone with a standard USB C cable.

I also have a USB C to HDMI cable.

Yeah, I plugged mine into my tv a few weeks ago, using a USB-C dock, so I could play the new Katamari game on the 65" screen.

With a ps5 controller hooked up via bluetooth, it was just like having a console.

It was since at least the iPhone 4. I still have the old digital AV connector from before they switched to lightning. It came with a hdmi port and a usb port. You could plug an SD card reader into the usb port and use it as an external HDD for transferring files.

You can therefore stick a sim in a dumb phone. And still jave a desktop smartphone for any bank or service that demands an app.

By using a monitor you psychologically change the device from a time sink to a tool.
