A:AnswerI have the MU6290 and just bought it and I love it and it does have a setting where you can leave it on and over time it will dim the background quite a bit.
A:AnswerI'm using this TV with a Mohu Leaf indoor antenna and pull in almost every local Atlanta channel. I have to move the antenna about 6 inches if I want to watch the second of our PBS channels. I would recommend experimenting with the antenna position and possibly looking for an antenna amplifier. One of the nice things about this TV is the two USB ports, so you could power an antenna amplifier and still have a USB port.
A:AnswerIt has the port! I bought this for my mom she has cable but the hook up she has in one room is with the antenna!She is complaining about the colors at night time the picture quality is not good with out the cable!!Its not bad for the price and size but!I believe cable would be best for the HD quality!!
