Arcade game machines have evolved over the decades, and so have their display technologies. The most common display resolutions and aspect ratios vary depending on the era and type of game.

Classic Arcade Machines (1980s-1990s):

- CRT Monitors: Typically used 4:3 aspect ratios.

- Resolutions: Ranged from 320x240 (standard for early games) to 640x480 (for later titles).

Modern Arcade Machines (2000s-Present):

- LCD/LED Screens: Often use 16:9 or 16:10 widescreen formats.

- Resolutions: Common ones include 1280x720 (HD), 1920x1080 (Full HD), and sometimes 2560x1440 (QHD) for high-end cabinets.

Specialized Arcade Displays:

- Some racing or fighting games use ultra-wide formats like 21:9 for an immersive experience.

- Lightgun games may still use 4:3 CRTs for compatibility.

Understanding these standards helps in restoring classic cabinets or designing modern arcade setups. Whether you're a collector or developer, knowing display specs ensures authenticity or optimal gameplay.
