Krypton 4k 30hz support

Hello everyone.

I have a Vizio D55u-D1 4k TV and am using an Nvidia Shield TV player and Kodi 17.0 Krypton won’t let me change the resolution to 4k. I have also tried to do it with my T96 Pro Android box with the same result. Kodi will let me change to 4k with the other Samsung 4k TV @ 60HZ however. I have switched the Android display settings to 4k as well.

Any idea if this issue will be addressed in the next version release?

Thanks very much for your time and help!
