Nonsense. 1084 can do it. In fact, with those old monitors, you can easily stretch 200p modes on PAL to use the whole screen.
Indeed, this is why nobody knew the Atari 520ST had C64 style borders all around until the 520STM 3 months later was plugged into TVs. Most 80s monitors had horizontal or vertical adjustment for placement and zoom controls, most TVs have variable resistors inside on the PCB.
