Field of Vision depends on Display Resolution
Understanding FOV requires you to know about display resolution which I have detailed here Resolution Vs Pixel Density in Displays – ALL YOU NEED TO KNOW. Consider the following image which has two screenshots of a popular game Age of Empires.
The high resolution screenshot has higher FOV than the low resolution screenshot. The basic idea is that high resolution display has more number of pixels and thus it can show a lot more content. Similarly a low resolution display has less number of pixels and thus it can show less content.
The game images with low resolution covers only less content since it has low resolution. Consider the same game in which you are extending the resolution to 1920 x 1080 which makes the games to display more content. The display with resolution 1920 x 1080 shows 2.63% more content than a display with resolution 1024 x 768.
