Thanks - will see what specials are available at Black Friday and decide from there.
Another bummer is that I have an LG Soundbar that accepts Bluetooth and SPDIF as inputs - as luck would have it, the current TV has no optical out, neither does the PS4 Slim or the NUC. For now I am using Bluetooth on the NUC but it's not ideal, and the PS4 Slim sees the Soundbar but refuses to connect. Oi vey!
So an SPDIF output on the TV is definitely a non-negotiable but it seems as if Hisense has it sorted in this regard
