One difference between Monitors and TV used to be that Monitors used RGB Subpixel-Layout and TVs used BGR. (i.e. TV panels are upside down)

Configuring subpixel-layout per monitor is something that most OS won't allow. So if you use several monitors, you usually have to mount the BGR-ones upside down. (Otherwise fonts will be blurry...)

For some time now there are really cheap 4K Monitors with BGR-layout available. If you mount those upside down you're fine... (I use LG 4K Monitors mounted upside down in combination with other screens)

Subpixel hinting isn't that useful at high DPIs though. Apple has ditched it entirely in macOS, regardless of monitor DPI, and gone back to standard anti-aliasing.
