Sony XBR960 CRT Calibration

Last week, I had the priviledge of calibrating an Sony 34-inch XBR960 CRT. This is probably the last truly great CRT HDTV. It has been discontinued but there are still some deals out there. MSRP is around $1800 but they can be found for under $1000. The first thing I noticed is the excellent black level. Not only are the blacks really black but it was totally stable through the different APL Pluge patterns. I had superb notes on this TV's service menu so I dove right in. Grayscale is adjusted for the Neutral color temp at 1080i. Then you adjust offsets for the other scan rates and color temp presets. A complete set of decoder controls is also available. Once again, I was able to use my Progressive Labs analyzer instead of filters to really achieve accuracy. I also adjusted the image position and overscan. When I had finished, the gamma curve was a perfect 2.2, not 2.19 or 2.21 but 2.2! Grayscale tracked within 200k of D65 with all Delta C* points below 1.

Needless to say, the customer and I were very pleased. He is very proud of this set and it was my pleasure to calibrate it for peak performance. Even though CRT is nearly gone from the marketplace, there is still a large base of customers with quality sets that have yet to realize their full performance potential. I look forward to the next one.
