I had my 65HX81 calibrated by Gregg Loewen last night and the set is now twice as good as before. Gregg was very nice in explaining everything he was doing and never left you out to wonder about anything. My DVD's and HD look fantastic, my wife even noticed the difference in color. My geometry and convergance is perfect and my overscan is set at 4%. This was money well spent and I feel like I have a new TV now. So don't wait and get your set calibrated, prefebably by Gregg.
