HDR passthrough issue
I have a brightsign xt1143 hooked up to an nvidia shield and any time I try to play 4k HDR content on the shield, it is downgraded to 4k SDR or 1080p depending on the source of the stream. I’ve tried playing 4k hdr content directly from the brightsign player itself and it appears to work fine. I’ve also tried hooking up the shield directly to the tv and the hdr content plays fine that way as well. It seems as though there is some sort of handshake issue whereby the shield doesn’t recognize the brightsign input as hdr capable even though there is an hdr capable tv on the other end. Any help or thoughts would be appreciated. Thanks.
