Yes, monitors have been forced to include scalers that enable OS to use extremely low resolution modes. The 'problem' is that this mode of display makes the first experience a user sees to betray the extremely high fidelity modern displays are actually capable of. I understand if you personally feel that starting up into 80x25 text mode is still acceptable in 2019 with 4k displays, and that's fine. But if someone wanted to build a brand new OS which was designed from the ground up as if it was built for and with the actual technology we have now, rather than the technology we had 30 years ago, I am just asking how difficult that would be.
