Unable to display full screen image on external monitor from an iPhone
How does one get a full screen display on an external monitor connected to an iPhone X using a Lightning HDMI adapter/cable? I only get an image on the monitor that is narrow and tall. I can't stretch the image to fill the screen so there is a great deal of wasted black space on the monitor. Image adjustment settings in the monitor setup only shrinks the image size even smaller. What is the solution here? Advice appreciated.
iPhone X, iOS 14
