A luminosity rating of 4,500 nits allows you to watch “the world’s largest outdoor TV” in direct sunlight. The latest creation from tech/luxury lab C Seed is this 301-inch 4k UHD TV made of carbon fiber & titanium that has a built-in 2700-watt sound system & raises up out of the ground via remote. 48-bit color depth supports 281 trillion colors. After the 40-second mechanical unfurling of the fold-up 7-panel screen, your guests won’t even care what you want them to watch. Price tag is equally impressive.
