Apple HDMI iOS no signal not working

The cable may not be forward compatible with newer standards and devices. I have a bunch of cables I bought from Best Buy over the years that won’t work with my Epson projector or new LG TV. But plug in my old Monster Cable and everything works.

LG has a test mode for cables. The cheap ones never pass.

I’m calling BS to all of these “solutions”. Tried them all and still no signal. Disappointed and frustrated with Apple and the lack of support. Feel free to upgrade yourself into obsolescence. 🫡

Indeed, Apple's Lightning to Digital AV Adapter firmware will be automatically updated by the iPad when needed.
