Hello, I'm not sure if this need to be implemented on Kodi side but I'll just post it here since Kodi forum is down for a while now.
Currently if video resolution is greater than GUI resolution Kodi will automatically switch to that resolution, but not the other way around. Can we implement this feature?
For example, if I set GUI resolution to 1080p on a 4K TV and:
1. Play a 4K video, resolution will be switched to 4K.
2. Play a 1080p video, resolution stay at 1080p.
3. Play a 720p video, resolution stay at 1080p, video will be upscale to 1080p by Kodi.
In the third case, it creates extra load on hardware and I personally think the TV can do a better job at upscaling.
