So I bought an official 2-4 adapter I think 4? it has a usb C end so at least 3. And this cable: https://www.amazon.com/dp/B01AKP8Z4C?psc=1&ref=ppx_yo2ov_dt_b_product_details

The display doesnt respond at all. Ive seen forum threads that suggest this wont work no matter what cable, but were not tested with a model this old. My impression was that the oldest that can be used is tb 3.
