Answer 1

Fonts

Answer 2

fonts - size and anti-aliasing (smoothing)
distance Regardless of the OS - stay away from the monitor, 60-80 cm from the eyes, not closer (the ruler will not let you deceive yourself). And increase the font size for comfortable work at such a distance.
brightness Excessive brightness of the monitor noticeably tires the eyes. If in one of the OS the brightness is controlled programmatically, try to correct it. For evaluation, a white sheet of paper on a table (lit by external light) should not be very noticeably darker than the white on the screen. Otherwise, the brightness of the monitor should be lowered.

Answer 3

Since for some reason you are talking about memory and the processor in such a question, it will not be superfluous to check whether the "native" resolution is set on the monitor at all.
And yes, information about the monitor and connection type can help guide you to the right decision.

Answer 4

I have exactly the opposite, on Ubuntu soft beautiful fonts and a desktop interface, but on Windows everything is somehow wrong. It's more a matter of taste. Both here and there are native Nvidia drivers and the maximum resolution with the maximum refresh rate.

Answer 5

And the proprietary nVidia is either installed or manually installed not from the office. rap?
