What is a Windows Projector?
The question of what a Windows projector is, starts with a discussion of what a PC-less projector is. A PC-less projector is a projector where an operating system, generally Android or Windows, is built into the machine, bypassing the need to connect a separate PC to provide content. To complement its operating system, PC-less projectors typically feature pre-installed software and apps that allow it to perform a range of tasks from productivity-related jobs to streaming media. Furthermore, PC-less projectors are able to connect to the Internet, including via wireless connections, to access content on the web, download files located in the cloud, install additional software/apps, and to support wireless casting from BYOD mobile devices. With a range of PC-less projectors available to them, business users – particularly large businesses and corporations – have keyed in on Windows projectors as the most viable solution due to their compatibility with most office-related hardware and software, the familiarity and functionality of the Windows platform, and the strong security features incorporated into the operating system.

Whereas this article is focuses on solutions for business users, there are home entertainment PC-less projectors – most commonly known as smart or portable projectors – which tend to be powered by Android TV and mainly revolve around streaming apps.
