I know this may be a little late, but I would avoid the 6300u. I bought one for $999 at best buy and returned it 2 days later.
First off, there are no individual color adjustments. Even in the service menu there are no individual color adjustments for HDMI connections.
There was a green push on my display that I could not get rid of. The picture was very pixelated and there was a ton of ghosting and artifacts. Even after calibrating the color and tint with a blue filter, the colors were still all messed up.
That being said I stepped up to the 830u and I have been very happy.
I really tried talking myself into keeping this tv just because of the price, but I couldn't do it.
