i have a Samsung JS9000 48 inch curved tv and for nearly a year now i have been messing about with the picture on various sources but always the picture was never correct and disappointing for such an expensive tv to the point i was about to trade it in for the new LG OLED HDR tv my main reason for this was that i have just purchased a 4k HDR panasonic blu ray player - while reading some reviews on HDTV test i come across this link to have my tv calibrated so i thought well lets give that a go - very quick reply from Vincent and reading the reviews from other customers i arranged for Vincent to come out to my house in Reading (Vincent is based in Manchester) - now Vincent is a total pro and a perfectionist and being one myself really impressed me the way he explained every single adjustment and how the tv should be mounted to the wall an easy tilt adjustment as i had never even noticed the picture difference between sitting down and standing straight on - anyway vincent spent nearly 4 hours calibrating my SD/ HD , HDR , 3D , and gaming settings and all i can say is this guy should be on tv as he is a miracle worker my tv picture now looks amazing on all sources i have tested various movies etc and wow i cannot stop smiling - yes its expensive at just over £400 but well worth it especially when i was considering spending £2700 on a new tv then i would have needed to spend this amount again have it calibrated!! so vincent has saved me £2700 !!!! and i have a picture to die for and looks better than the tv i was good to purchase !! - if you are thinking about this service i fully recommend it - vincent is a pro , very pleasant guy and does not mind whatever you request him to do (to your tv that is!) - GO ON DO IT TODAY AND SMILE AT YOUR BRAND NEW TV !!!!!! 100 out of 10!!!
