Vincent arrived on time and did not hesitate to set up his equipment and explained each part of the process. He looked at my settings and in a professional manner asked where I got them from..I replied 'the Internet' and some forums...a little smile was made..I could sense better things were on its way.. He took the readings and as you guessed were all over the place..too much red. Don't worry he said we'll be able to compare these settings with a calibrated one. He then took the time to go through the gray scale and all the colour settings. After talking me through what Vincent was doing and the computer noting that all were good Vincent took to the SkyHd channels, in particular the news ones as these give the tv an opportunity to show lighting, shadows and text. Vincent flipped between prof1 (my settings) and prof2 (calibrated settings). You notice the difference straight away. The colours are better and don't looked washed out. Spot on. Next was to review the blu-ray..the black bars were black..proper black..in my settings there was always has a tint in the corners..not anymore..in addition the picture was more uniform with much better detail. Finally I used Netflix to watch 4K. Sword of destiny..wow the opening scene with the mountains was amazing and the skin tones were much more detailed. The one area which shocked me was that the sharpness bar was moved from 50% to Nil..obviously a misconception that this needs to be on as the picture is more shaperer than before on zero settings. All in all money well spent and if you are sceptical (which I was) watching the new UHD on sky Q at the weekend was out of this world..hats off to you Vincent..
