Modern smart projectors are no longer simple display output devices, and most mid-to-high-end models support independent operation to replace basic desktop and laptop computers, while entry-level non-smart projectors cannot work independently without external host equipment. The replacement capability depends on the projector’s built-in system, hardware configuration and extended interface richness.

Smart projectors equipped with Android TV or customized smart operating systems can fully meet daily office and entertainment computer demands. These projectors have built-in CPU, running memory, storage space, Bluetooth and Wi-Fi modules. Users can download office software, browser, video apps and drawing tools directly from the official app store. Matching wireless keyboard and mouse enables document editing, online meeting, web browsing and multimedia playback without connecting an extra computer host. It supports multi-task operation just like a regular laptop.

Still, projectors cannot replace high-performance computers for professional work. Limited by miniaturized hardware, projectors fail to run large-scale design software, 3D modeling programs and heavy-duty online games. Their system compatibility is weaker than Windows computers, and file format adaptability has certain limitations. For simple daily office, family entertainment and student online study, smart projectors are competent computer substitutes; for professional design, gaming and high-efficiency office work, an external computer host is still essential.
