I have a 75" QN85B. When watching movies from my Nvidia shield in Kodi everything runs smoothly except some buffering sometimes. But when I try watching movies from my PC via Kodi I get a small lag every five seconds or so. The only workaround I've found is to make the TV see the PC in "Edit device type" as a PC and not a Home Theater as I normally have. And when I do that I only get two picture modes. Entertain and Graphic. Which make image look very crappy. Not Movie mode which I've calibrated. Can anyone help me get Movie mode back when the TV sees my computer as a PC?
I use a Denon AVC-S660H that everything runs through. But that does not matter as it's the same problem when it's connected directly to the TV.
