VGA is much easier to produce, and the RP2040 can do 1280x1024@60 no problem. The official examples use several clock cycles per pixel (2 IIRC, but it might be even more), but you don't have to.
I made half a terminal with that output, aiming for something that ran the original VT100 ROM. I never finished the emulator part, but I did write video output (including scan line emulation) for VT100 memory -> VGA. Adding SSH once the rest works should be perfectly possible. (Not bit banging ethernet at the same time, but using some external chip.)
I should probably put that online somewhere. Or finish it and then put it online.
