I am running a vizio e550i-b2 with a c61k in my living room. Ever since the client software updated to 0x10d1, the TV has been stuck on 480. All of the other resolutions are checked, and will test on the resolution setting screen, but the TV revers down to 480 right away, regardless of the resolution of the playing programming. Native is set to on, and so is screen format set to original format. I know the TV is not the problem, because I put in a blue ray, and the resolution played at 1080p. Any suggestions?
