If you're a budget-conscious buyer looking for a highly versatile projector that *claims* 4K and offers extensive app support, the ELEPHAS 4K Projector is a strong contender. Ideal for casual movie nights, gaming, or presentations, it offers a perceived 4K experience via pixel shifting and boasts an incredible 100,000-hour lamp life for minimal maintenance. Its automatic focus and keystone correction simplify setup, making it great for users who prioritize convenience and built-in streaming directly from the device. This is a good fit if verifiable ANSI lumens isn't your top concern and you want a feature-rich projector for under $400.

The WiMiUS K13 is ideal for users who prioritize verifiable brightness and a superior smart TV experience for their home cinema. If you're building a dedicated movie setup or need a projector that performs well in rooms with some ambient light, its 1200 ANSI lumens and native 1080p resolution deliver crisp, vibrant images. Google TV with voice control provides seamless access to all your streaming services, including Netflix, making it perfect for those who want a robust, integrated smart platform. While slightly pricier, its picture quality and smart features justify the investment for a more premium viewing experience.
