Since all of the sources you list can throw out/accommodate varying resolutions/content, you may frequently find yourself having to adjust as such. And then there's the issue of the HDTV/display settings too...
Does anyone have a yamaha RX-V667 receiver? I'd love to get this thing to put out a constant size on my screen no mater what video source I'm using. I'm also trying to optimize the video and audio. Any suggestions out there? I do alot with my Roku 3, Plex streaming and Netflix.
