In the mid 90s professional video game programmers used typically a 1920x1080 display, just to have a larger code canvas and display sharper text. From the 90s on 1600x1200, 1920x1080, 2048x1536 were resolutions one could find on professional displays. From the 2010s on resolutions increased tremendously and 3840x2160 became the norm for consumer and professional displays. When working with code you essentially work with text. You just want a big canvas and crisp text, thus high resolution.
