Both AMD and nVidia now have included Super Resolutions in their driver package.
What this means is that if you have a newer AMD or nVidia graphics card and you run drivers from 2019 or newer, you likely have the ability to up-scale your resolution through your GPU.
This allows you to get a higher desktop resolution while still have readable text because AI is used to up-scale the image, without much performance loss.
The display will still use the same (native) resolution, but the desktop will have a higher resolution. This is great, because now, my old TV is suddenly a 4k TV. :D (well, sort of)
I own an AMD card, but have no access to an nVidia card, so I don't know exactly how its called and where it is located. I just know that nVidia also supports super resolutions now.
For AMD, go to your graphics settings, display, select the display that you want to alter (multiple displays means, you have to change them for both individually). Enable Super Resolution and enable GPU upscaling. Now, if you go to change your resolution, you'll notice, a few additional resolutions have been added.
The resolution that says (recommended) is your native resolution, which will offer the clearest image, but a higher resolution is possible, and you can use a higher DPI to make the text a little bit more readable in case it is too small.
