iPad Air 3 zoomed screen using Hdmi adapter

Hi, hope someone can help.

I’ve connected my iPad Air to my Tv using an hdmi Lightning adapter, the issue I have is that screen is zoomed in and the top, bottom and sides are snipped - meaning I miss some of the read outs on the Tv. I’ve googled it but can only see anything people wanting to get rid of the black borders on the screen.

I’ve tried my iPhone and it has no problem at all, does anyone else have this problem and solved it?

No one can help me out?
