I already posted in the gt50 thread about some of the technical success of chad b's calibration, but I wanted to chime in here to comment on his professionalism, conduct, and overall customer service.
Chad was perfectly on time, and I happened to be his first ever "geek buster" calibration. His knowledge of my set was impeccable, and even though he did finish in his advertised "90 minutes", he took the time to answer all my questions as well as to clarify certain things he was trying to accomplish, all while I was running back and forth trying to also take care of 2 kids. Again his knowledge of my set was quite startling to the point of where it seemed he knew already where to take it before he even got there, if that makes sense. He was able to calibrate service menu grayscale, do a day and night mode, answer all sorts of questions, take the time to explain further as needed, ask me all sorts of questions about my viewing, all within 90 minutes while never looking like he was rushing and being very laid back overall. The level of precision and efficiency he displayed was remarkable.
I felt chad truly was interested in my normal viewing environment and viewing preferences, and his questions for me were greatly appreciated. One thing I noticed is that his calibration really took into account what would be normal viewing content under normal lighting, which ultimately led to a calibrated viewing experience that my wife and I are really enjoying at all times of the day with a variety of different content. The result was breathtaking and though I've had a previous set calibrated I could not believe how much chad had improved my picture. My technical knowledge of calibration is limited but it was clear chad is an invested and highly capable calibrator - I commented how his windows seemed small to which he replied he has done a lot of research on window size and its effect on measured performance as well as its correlation to real life viewing. This was also evident when I asked about the use of patterns/windows at 75% saturation level vs 100% saturation, which he explained was closer to real life viewing content and would have a stronger correlation to better viewing performance.
Overall the whole experience was as close to perfect as I could expect. Chad is super friendly and personable, and asks great questions and takes the time to really listen to what you are looking for. The geek buster calibration he offers is a no brainer IMO for anyone looking to get a set that does not have a CMS or limited calibration options - what he was able to achieve on my gt50, which by all accounts is pretty solid OOB, still leaves me in disbelief.
I hope the above comprehensively conveys that I can fully endorse the calibration services of chad b and am more than happy to provide a personal reference to anyone that needs it.
