Hi all, I now own a few devices that are capable of outputting at 4k, so I have some currently outputting in 1080p, ideally I want them all to output at 4k so i'm thinking of buying an amplifier. The only issue is since they are gaming consoles I ideally just want the video to pass through, so there is no extra input lag at all, do Amp's that are capable of this and good at it exist? if so which ones would you recommend please? thank you for the help
