Overscan / underscan Intel HD Graphics 610 + Fedora 25 (Wayland)

edit

Hello,

I just want to know how to scale my display properly in order for the screen to fit in the tv (cheap RCA tv doesn't have real underscan/overscan feature in its settings).

Back in the days (before wayland and intel hd graphics) I had found a way to achieve this with with X and nvidia-settings (had a parameter in nvidia-settings: ViewPortOut)....I know some people were doing this kind of stuff with xrandr ..... see link http://imgur.com/a/abv9n

Both options are irrelevant now as I'm no more using nvidia driver and I've switched to Wayland/intel/Fedora 25.

What would be the new way of doing this kind of overscan / underscan correction using Wayland + Fedora 25 + here Intel HD Graphics from Kaby Lake intel processor.

Thanks !
