Resolution 1024x768 (Doom (2016))

The monitor should be put in a suitable (extremely ancient) one.

in the video driver settings there is a similar thing - called Scaling, here is an example from Nvidia (right button on the desktop - Nvidia control panel), rummage there, turn on different options, and stop on the one that you like.
As for AMD - I don't know for sure, but I think there is something similar

auto- adjust the monitor when playing, it will tighten the monitor to 4: 3
