I bought a high resolution secondary monitor to attach to my laptop. Text was too small to read in some of the application that I frequently use. There was no provision to increase the font in the application like you have in your browser to zoom out/in.
I found a solution. Right Click on Desktop -> Display Settings and “change the size of text, apps and other items” setting to 200%. 150% was not good. Eurika! I got the Text in the application readable.
