PPM and Invidia shield AI upscaling

Would Nvidia shield is capable of upscaling 1080p picture to 4K? Is it worth it ?

I don’t get it. Why would you want upscaling to 4k since PPM is FHD?

The PPM will only be recognized as a 1080p display by the Nvidia Shield TV so it won’t push 4k to the projector.

Also, HDMI port of the PPM is only 1.4 not HDMI 2.0 so even if there is a way to force 4K output from the Shield, bandwidth will be limited.

4K content can only comes internal sources.

I would like to upscail the picture for better resolution

But PPM is 1080p so it is pointless to upscale to 4k since PPM will downscale to 1080p before projecting it.
