Hello there, I am working on a little project as a way to improve my cad abilities. I am hoping to build a custom fantasy computer to go along with the pico8 fantasy system. I am basing it off of the Mac se/30 but am obviously hoping to get that nice 1:1 aspect ratio.

Trouble is that decent size 1:1 screens don’t seem to exist as far as I have researched, I instead found a small 4:3 lcd panel I can use, and was originally planning to simply rotate the screen and let it render 1:1 while physically covering the top and bottom, but it seems to add significantly more vertical height than I anticipated.

so now I am hoping that I can shift the screen down and somehow get the PI to render only in the topmost visible section.

Included are a couple pictures of what I mean.

I am just wondering if there is a way, in software, to rotate and move up the screen, or at least the pico 8 window

    Assuming 1:1 aspect ratio is for the physical screen, the resolution most likely won’t be a square because of the rectangular shape of pixels. So you’ll need to calculate the resolution of visible part of the screen first. After you have found your resolution, you’ll probably need to add that resolution config under /etc/x11/xorg.conf.d/.
