Retro Games Appear Better on CRT TVs Due to Original Design and Display Technology
Key points
- Retro games were designed for CRT displays.
- CRTs use scanlines, not individual pixels.
- CRTs offered greater motion clarity for older games.
- Modern displays use sample-and-hold technique.
The Mismatch of Old Games and New Screens
Many retro games, particularly those from the 1980s, 1990s, and early 2000s, were developed with the technical specifications of Cathode Ray Tube (CRT) televisions in mind. When these games are played on modern flat-panel displays, such as LCD or OLED screens, their visual presentation often appears degraded compared to how they looked on original hardware and displays. This discrepancy is not solely due to nostalgia but stems from fundamental differences in display technology.
How CRTs Functioned
CRT displays operate by firing electron guns at a phosphorescent screen, drawing horizontal 'scanlines' to create an image. Unlike modern displays that render individual pixels and hold a full frame, CRTs continuously draw lines from left to right and top to bottom for each frame. This method of image generation contributed to a distinct visual output that older games were designed to utilize.
Motion Clarity in CRTs
A significant advantage of CRTs was their superior motion clarity compared to early LCD counterparts. CRTs did not use a 'sample-and-hold' technique, which meant they did not hold a full frame until refresh, resulting in less motion blur. This characteristic made low frame rate games, like The Legend of Zelda: Ocarina of Time (20FPS), appear smoother and less jarring than they do on modern displays, which only recently achieved comparable motion clarity with high refresh rates.

Reporting from
Retro games from the 80s, 90s, and early 2000s were designed for CRT displays, which handled motion and resolution differently than modern flat-panel TVs. This design context explains why these games often look less appealing when played on contemporary screens, as the original visual effects relied on CRT characteristics. The difference in display technology impacts how older games are perceived today.
