Fantastic service from Vincent at HDTVTest - he arrived bang on time and was very smart and polite. He talked me through every step he was taking in the calibration process and was very thorough in optimising the settings on my Samsung, making sure I was happy with what he was doing. I was very pleased with the results, and Vincent had retained my original settings so that he could show back-to-back comparisons of various scenes and I could really see the differences - more life-like colour, much better rendition of darker scenes, and better sense of depth. I'd always expected that a professional calibration would result in more subdued colours, but not a bit of it - colours are still fantastically vibrant, it's that they're just properly balanced. A happy customer.
