I had Vincent calibrate my 55" Panasonic GZ950. It took about 2 hours to fully go through all the settings and do the adjustments. He started on a TV that from the box only had the brightness turned down to -2 with all other settings as factory default. My preferred viewing was Professional 2 warm 1. After the calibration, Vincent showed me the difference from my preferred setting and the new calibrated setting he had just done. I should say before calibration the TV had far too much blue. The result was apparent straight away as he flicked between a still frame of the golf. The colours were more natural and truer to life. On scenes with a bright light source, like the sun, there was less banding and on low bit rate sources the pixelation appeared to be far less. I'm really pleased with the result and would definitely have a calibration carried out by Vincent again.
