Check your local Craigslist or other classifieds for cheap old GPUs. Or if you have another PC, borrow the GPU and power supply just to get it to boot.

You start with base HP at level 1. Every time you level up, you roll a die (which die is determined by what class you are playing) and add your constitution modifier.

It’s less convenient, but you can just not connect the TV to the Internet at all. You can connect a computer (pi or something similar) to that in order to play videos or stream from. Or an Xbox / PlayStation for ease of use (yes I know those have privacy problems as well but they are much less intrusive).

Another thing you can do is set up a pi-hole on your network and blacklist all the domains your tv uses for ads and tracking.
