My receiver only puts out 1080p and i am looking for a device that supports arc that will deliver me 4k with audio on my surround sound will thisdoit?

Will it split to two different resolutions? i have a 4k roku, 4k & 1080p tvs. can it send 4k to one and 1080p to the other? or is it lowest resolutio

Does this support a firestick as the input device to a tv and sound bar?
