Hi to al, I have a 4k Panny tv. Yamaha avr 3030 with 4k pass through and HP SFF PC all handle 4k. I have bought decent leads which are supposed to handle 4k. I cannot get 4k at 60hz only 30hz is there something I,m supposed to do with the Yammy 3030. Leads are already converted from display port on pc to HDMI on Yammy AVR and connected to NR 4 HDMI connection on back of TV as recommended to enable 4k pass through. Graphics on PC are supposed to handle 4K. I,m lost as to what to try next as Ive spent hours messing and got nowhere. I would be greatful for any advice / help. Many thanks in advance to anybody who has time to reply. Cheers Rob.
