Cannot extend desktop / no arrangement option under settings
I want to use an extended desktop with an external monitor. I have iPadOS 16.1.1 and an iPad Air 5th gen with M1 chip.
I purchased a USB-C to HDMI 4K cable, plugged it in, saw a blue icon in the top right appear and a few seconds later my display was mirrored. It doesn’t fully fill the display.
I can see the 2nd display correctly identified under Display and Brightness > Connected Displays … but no “Arrangement” tab I’ve read about. I have stage manager turned on.
I’d appreciate any help as I understand extended desktop should work with my setup. Thank-you.
iPad Air, iPadOS 16
