When evaluating a Jade Projector, you must prioritize Brightness (measured in ANSI Lumens), as standard Lumens can be misleading. For professional or well-lit environments, look for at least 3000 ANSI Lumens. Additionally, verify the Native Resolution; ensure it is at least 1080p (Full HD) or 4K for high-end jade display, as 'Supported Resolution' does not guarantee image clarity. The Contrast Ratio should be at least 10,000:1 to ensure deep blacks and vivid colors, which are essential for showcasing the intricate textures of jade products.
