Well chaps it's now been just over 8 days since Vincent came to calibrate my Panasonic 65 DX902B and the results are amazing. Any body that doubt's the results is really missing out big time in getting the best from their new 4K TV. The difference even in "Off Air 1080i" broadcasts are noticeable but when the daylight fades and you start on your Blu Ray and 4K discs then your jaw will drop with the details it brings out in the pictures ! Vincent was very professional and takes a lot of pride from his job and guides you through all the things he was doing and explains his steps clearly. Overall extremely pleased with the calibration service and would recommend Vincent's services to anyone wanting to squeeze every last detail from their TV's.
