It is very difficult with out using this disc to get the best performance out of your new HD television.Being a TV engineer it was very easy to achieve good display callibration.Recommended for anyone pushing that extra ounce of quality from new TVs.
Got this for use on a Panasonic TX-P46G20. Worked well, not that much needed tweaking. Haved used the digital essentials DVD in the past. The patterns on this disk seemed a lot better, although you don't get the video tutorials.
