CRT emulation for video refers to the process of mimicking the visual characteristics of traditional cathode ray tube (CRT) displays in digital formats. This includes replicating the unique color profiles, scanlines, and phosphor glow that defined CRT screens, often enhancing the nostalgic experience for gamers and retro enthusiasts. By using various software and hardware techniques, CRT emulation allows modern displays to recreate the warmth and depth of classic gaming visuals, providing an authentic experience reminiscent of past.
