Jeff Murray spent the first 20 years of his adult life serving Uncle Sam in the US Army. During that period, he spent six years in Germany where he and his wife worked at the Mannheim Audio/Photo Center. Jeff represented Akai, AR, and Pioneer and was destined (or condemned) to a lifetime of technology.

After the Army came Sencore, where Jeff built the AV Division and brought to market many products for calibrating AV systems and helped to facilitate the Imaging Science Foundation's rapid growth; in fact, he still serves on the ISF Research Labs board.

Jeff now runs SpectraCal, a multifaceted company dedicated to the attainment of the "perfect" picture on screen. With decades of experience spanning electronic cinema, home theater, commercial AV, and digital signage, the company focuses on display optimization through calibration achieving and maintaining the integrity of the original content as the cinematographer, videographer, or graphic artist intended. To this end, SpectraCal considers the variables of the display, screen, and environment with the role that each plays in the attainment of the goal. Understanding that displays out of the box cannot perform at their peak and will not produce that "perfect" picture, SpectraCal has developed software and hardware solutions to permit anyone from beginner to expert to optimize images in their unique environments. Jeff and his team are currently working on new products for digital signage, PC gamers, digital photographers, video walls, and medical imaging.

The color slides are flat solid colors in 3 gradients of red, green, blue, plus white (to gray I imagine its 50%) to black. I dont know if we can link to other sites but people on AVS forums get the slides from this site: eaprogramming.com in the downloads section. You either use them in a thumb drive or make a dvd-r and loop them. If you suggest one 50% gray field, however, I'd rather follow your advice!

If you can set it up to endlessly cycle through the different colors over and over, that's probably okay. But I think a solid gray field would work just as well.

Excellent episode, Scott! Planning on getting a new PDP in the near future and I have a question about leaving a 50% gray scale image on a PDP all weekend for break in: is there any advantage using a color slide vs a single 50% gray image?

Glad you liked the show! By "color slide," do you mean a flat color field, say red, green, or blue? If so, a 50% gray field is definitely better. The idea is to exercise all phosphors equally, which a 50% gray field would do. A color flat field would exercise one phosphor more than the others, so I wouldn't do that.
