I have a Toshiba model 42HL196, it's full HD 1080p, but my xbox will only play at 720. I'm running my stuff through a sony receiver that supports HD. I've checked all of the settings on my TV, Xb1, and sony receiver. For some reason it won't play at 1080p. I understand some say that there's not much of a difference between 720 and 1080, but I have 1080p so I WANT to utilize it. I tried bypassing the receiver by plugging the hdmi directly to the tv and ran the audio from the tv to the receiver but still no luck. Any help would be much appreciated!
