Screen size does not fix.

Since the new upgrades the screen size is too big for my 7 YR old Toshiba Laptop, which I use constantly. I Can not access the x or the scroll bar. The character's are Hugh, stretched and distorted. I have followed every single step listed in troubleshooting
and even paid two computer techs to fix it. NOTHING WORKS! There used to be a simple one step adjustment: Settings: Display: Screen Size. Neither, Resetting, troubleshooting app, driver updates, changing to another resolution (which btw is suggested as a
fix but non existant) nothing works. I am at wits end. The last guy I paid to fix it suggested I just buy anew unit? I can't afford that. Please please address this issue asap. Thank you
