I bought an Intel NUC5i5RYH with 4K capabilities. I would like to have 4K resolution on my Philips TV. I recognized that 4K over HDMI isn't possible with that NUC. My Onkyo receiver and my Philips TV both have no DisplayPort. I'm looking now for a solution to get 4K@60hz from my NUC to my TV including the sound. When I use a DisplayPort Adapter (to HDMI) I get only 4K@30hz with no sound. Any ideas?
