[FEATURE REQUEST] Overscan custom sizing

I would love the ability to be able to scale the size of the image.

I’m currently running Plex on a Roku Express Plus to a vintage CRT TV. The overscan on this set cannot be adjusted. It would be great to be able to adjust the size of the picture within Plex. On my old WDTV there was an option to scale the image by 10% at a time. A similar feature would allow custom sizing to get the menu and media play back perfectly sized.

I know there is the overscan option, but this only changes the menu layout to make it more usable, not the actual playback of media.

I hope this is something that can be added in the future. Not too many people probably use vintage CRTs with Plex, but to get the perfect look, this feature would really help.

Thanks!
