Resolution output on Shield

Hi !

Been using RA for years, but not so much on an Android device. I installed RA64 on my Shield tv pro 2019, connected to a 4K Oled Tv (LG CX).

Problem is : I can’t find any way to force RA to launch in 1080p instead of 4k, unless I change the output on the shield settings, wich is a bit of a pain beacause I use the shield mainly to watch movies in 4K.

Why 1080p ? For smoother framerate and demanding shaders.

Thanks !
