Is there any TV on the market with picture resize setting per input channel? I don't know any. My TV has 4 hdmi, should each one have resize settings? Amazon Fire TV media box has this resize picture setting and works just fine. My Sony Blu-ray player also had it. The awesome Roku is the only device that doesn't have it.
By the way, my TV is a LG 55la7400 55inch 3d 1080p smart TV.
