How to improve the clarity of a screenshot?

Question

Image processing

I started publishing on Ya.Dzene and the topic involves the active use of screenshots.
Screenshot FHD image of the screen from which 20-50% of information is cut out. Naturally, the final quality of the eyes is not very pleasing.
Are there ways to improve the quality?
Roughly speaking, it is necessary to make the miserable 700 * 500 pixels images become watchable on a 5-6 inch screen of a modern smartphone.

Answer 1

You are talking about very subjective things, but I will still try to give you a general direction.
When you take a screenshot taken from a screen with a standard pixel density (not retina and not 4k, but 75..96 dpi), and then show it pixel by pixel on a phone screen or a screen with a high pixel density, it looks too small. The solution that immediately comes to people's minds is to stretch the screenshot already in the layout. Either the full width of the content, or twice. And although the second option is more logical, it is no better than the first, because the screenshot cannot be enlarged using browser-a, since in this case an anti-aliasing algorithm is used, which inevitably blurs the sharp borders of different colors in the screenshot. In general, the only true way is to double the screenshot in a graphics editor without interpolation, by simply doubling the pixels. And insert into the code of the article in its true size.

Answer 2

set the scale of the interface to 200% in Windows (or whatever you have).
