Final answer:
There are numerous functions to display text across different programming languages and platforms. Resolution matters less for text display, with 1-2 MP being sufficient for screen display.
Step-by-step explanation:
When dealing with displaying text on screens, there are various functions available across different programming languages and output formats to meet your needs. For web development, functions such as document.write() in JavaScript or echo in PHP are commonly used to display text. In desktop software development, functions are dependent on the graphical library being used, such as System.out.println() in Java for console output or MessageBox.Show() in C# for Windows forms. In any case, the resolution of the display screen, often measured in megapixels (MP), matters less for text display than for image quality. While experimenting with screen display settings, it is suggested that for text, you probably won't need anything larger than a 1-2 MP setting as recommended by LibreTexts™.
