I really had my doubts about spending so much on an ISF calibration. I'm about as cheap as they come and didn't think that I would notice any difference with a properly calibrated tv. 3 and 1/2 hours later I was proven wrong. Greg Arrived on Time and was well dressed and started work on our hitachi tv. I had to work the first half of the day so when I arrived he had just finished the tv and I was amazed at how much better it looked and there was no more glare. I then watched Greg calibrate Mitsu 55413. This was 4 month old set that I thought looked pretty good out of the box. He removed the glare screen and put in the Black lining. This made huge difference and I was already thinking that I hadn't wasted my money. For the next 3 hours he worked the remote control like a mad man only stopping to get more diet coke or answer one of my questions. When he was done he showed me some for the movie the fifth Element and showed me things that I have never noticed before about the colors. He then gave me a print out of both sets and I wrote down the setting just in case something happened. He then jumped in his car in the pouring down rain and headed for his next job in MS. It has now been several weeks since Greg has been here and I am even more amazed each day at my PQ. The slandered Definition stuff looks great and the HD shows will blow you away. I can't wait to watch football in HD next season. I watched Miracle the day before Greg was here and re watched it the day after he left and could tell a big difference the second time . The colors were more accurate and it was much easier on my eyes. If your on the fince about having your TV calibrated by a true professional. Do yourself and your family a favor and give Gregg Loewen a call.
