I am extremely frustrated that the iOS/iPadOS Remote Desktop client still does not offer custom resolution and scaling settings. Every other market available alternative now does so. For instance I would like to connect at 1920 x 1080 at 125% to mirror my normal screen and so forth. The only screen using scaling is the “retina” option and that makes the screen so small and does not match the last two years of iPad PRO devices anyway.
This has been raised so many times and voted for but simply gets ignored!
