I’m attempting it with my iPhone XR, using screen mirroring to an external display, have Bluetooth mouse & keyboard, have Apple’s Lightning to Camera adapter for external drives (which are hooked up via a powered hub). Here’s the biggest obstacle: The iOS 14 iPhone screen viewed on external display (19”+) is much too large (except for videos, which fill the screen/display). In landscape position, a “standard view” lower case letter “e” is about 0.2” or 5.1mm tall, whereas on my iPhone screen it is about 0.06” or 1.5mm tall (as measured by digital caliper). I need to zoom way out (3x or 4x) so there is more content shown on iPhone screen. This would make it difficult or impossible to read on the iPhone, but I want to work with content viewed on an external display. I’m using my iPhone as my only computer. When away from my desk and display, I want the “standard view”, but when at my desk, I want to view much more content on my large display, thus I need to zoom out 3x or 4x. I use “screen mirroring” for the external display, which could also be a monitor or TV. Is there a solution?
