Linus Tech Tips - I made the BRIGHTEST Gaming Monitor in the World!
The video discusses the process of transforming a standard gaming monitor into the brightest one ever created, emphasizing the trend in display manufacturing towards increasing brightness. The creators experimented with various LED types and settled on the Cree CXB3590 due to its compact size and high light output. They faced challenges with power consumption and heat management, using multiple power supplies and a custom cooling system to handle the thermal output. The project demonstrated that while extreme brightness can replicate sunlight-like conditions, it also poses risks such as potential eye damage and overheating. The creators concluded that while full-screen brightness at such levels is impractical, targeted brightness could enhance visual realism in displays.
Key Points:
- The Cree CXB3590 LED was chosen for its high light output and compact size, costing about $28 per unit.
- The monitor's power consumption exceeded 3500 watts, requiring multiple power supplies and cooling systems.
- Extreme brightness can replicate sunlight but poses risks like eye damage and overheating.
- Targeted brightness, rather than full-screen, could enhance realism in displays.
- The project highlighted the need for better backlight and filter layer control in future displays.
