Personally I don't mind seeing only the LaTeX code and looking at the pdf once in a while after compiling. But a second screen to keep open and accessible background papers or notes would be very convenient
I’ve been looking for an eink screen for exactly this kind of thing.
Unfortunately they only seem get be put in expensive tablets, or monitors that sort of want to be a main monitor replacement (expensive).
There’s an eInk panel that seems sort of niche-popular, 7.5 inch with 5s refresh, reasonably priced (used in some waveshare projects) but it seems that you can only get the bare board unfortunately.
