Thinking of buying the new 9.7" iPad Pro for my wife to replace her old iPad. I'm wondering if it could also replace her old Windows PC. For "lean-back" tasks (email, reading, etc) she loves the iPad. For web surfing, online shopping, web videos and occasional spreadsheet, she prefers the PC's 22" screen and a physical keyboard.
Is there a way to send the iPad's screen to a 4K monitor via the Lightning connector, and turn the iPad's screen into a multi-touch trackpad. I know iOS doesn't support mouse cursor so the GUI would be a problem. Does anyone have a creative workaround (without jailbreak)? Thanks for reading.
