Why is it so hard for a camera (iPhone camera at least) to take a solid photo of a screen?

Always these weird lines

Those lines really exist. Your screen is a grid of pixels made of red, green and blue dots that glow. Your phone has its own grid of light sensitive photosensors that react to red, green and blue.

No way are you going to get those grids just lined up. So the phone’s grid of pixels shows the monitor’s grid of pixels more clearly than your human eye does. There’s a reason every ad for a phone or computer says that “screen images are simulated” or such in the small print.

Seriously, people should stop trying to take photographs of screens. I don’t see this problem “going away” unless someone trains an AI to fix photos. If it’s your own computer, take a screenshot with the PrintScreen key or whatever tool your operating system offers and use that instead.
