I am unable to configure the CHM files optimized for High-Resolution display. In Help and Manual tool, there is an option to configure the CHM to optimize for High-Resolution display. Is there any workaround to get the text appear larger in High-Resolution display without doing manually zoom in?
It's interesting to hear that another tool has some option that allows configuring a CHM differently. Are you aware of what exactly the option does to achieve this? To my knowledge, there haven't really been any changes to CHM files in many years. So my curiosity is getting the better of me.
Never mind, looking at the links you supplied now.
In your CSS, have you tried configuring the font sizes to 100%?
