Computer Screen Slightly Zoomed In

For some reason, without a settings change (I've checked and recheck a million times over) my computer screen is slightly zoomed in. About a half inch on each side is off the view, including the toolbar at the top, dock at the bottom, etc. It always is like that when coming out of a shut down or sleep since the issue began, but I could always fix it (until the next time) by shifting the orientation in settings and switching it back. Now, that fix doesn't work. I've exhausted the internet, checked display and resolution settings, restarting the computer, accessibility zoom stuff, everything in existence. If anyone has a real fix I would be eternally grateful. I'm suspecting I'll have to get a new monitor due to some other issues that seem more monitor than computer, but I'd rather not unless I have to. I have a spare, similar model to mine, used to be my brother's before he went off to college, I'd just have to work out all the cords and ports and stuff, but that's time I really don't have.
