This. For best results, get a 4k TV that supports chroma 4:4:4. I also agree with getting a 13" MacBook. This will make it much easier to carry around from class to class. If your experience is anything like mine, you will mostly be taking notes on the laptop at school, with maybe some light browsing and messaging. When you need to perform heavy work, such as creating and editing spreadsheets, coding, writing papers, or other work that has you switching apps a lot, you can connect to the TV and external keyboard. Another advantage to getting a MacBook, is that if your vision becomes so much worse that you have to start using a screen reader, you already have one built in, so you could simply turn it on and start using it. It's easy to learn, too.

I did reach out to ADP but they have a cost cap of $1200, which I’m grateful for, but it obviously won’t be enough to buy I bigger screen MacBook. Worst case scenario, I’ll look at some
Windows laptop.( ordered one but I’m returning it )

Yes, also have RP and screens that are too large drive me crazy. I was gifted a monstrous ultrawide monitor once but I still just use my 13" laptop screen because I lose track of the cursor and windows on the big screen.
