Hi,

You can get the headphone seperately and into the headphone Port on the side of your flat panel Television.

Thank you

As it is new, take it back for replacement. If you bought in online, have it replaced as it may have been damaged in transit.
Don't bother to try and repair it, it is not right.
Hope that helps.

The maximum resolution of any LCD is set accordingly to its specifications. You cannot increase the resolution i.e more than the maximum limit.

Advisable to check the specifications you want first before you buy anything.

Unfortunately that sound like a defective LCD panel. You can verify this by plugging the system into an external monitor. As long as the shimmering band does not appear on external display then it is the LCD. If it is under warranty I would suggest taking it into Apple.

did you ever find a solution to this problem ?
