Engadget's guide walks through using an iPad as a second screen for either a Mac or a Windows PC. The premise is simple: the tablet can provide some much-needed extra screen space for users who need more room to work without investing in a traditional monitor.
For business users, this could be a practical way to improve productivity while working remotely or at a desk. Because the iPad is already a common device in many households, repurposing it as a display may save money compared with buying new hardware.
The article notes that the process is not the same for both platforms. Mac and Windows users will need to follow different steps, but the overall benefit of expanding your workspace remains the same.
