It looks like D* has only ever shown one 4k NHL game and that was a few years ago. Rogers (Canada) has several 4k games on the schedule for viewers in Canada but doesn't look like D* has any plans to provide these 4k telecasts in the US. No US network (NBC SN, MSG, etc.) is currently producing any 4k NHL games (only Notre Dame football on NBC via ch. 106, it appears), but SN (SportsNet) in Canada is producing some 4k games in Canada. Hopefully this will soon change.
