Projection TV Troubleshooting: What is an ISF Calibration?



ISF Calibration

Imaging Science Foundation was established on the premise that displays should look the way their designers intended them to look, based on specific standards set by ISF. When a projection TV is calibrated by an ISF Certified calibrator – and the calibration is done correctly – the colors will match industry standards. Specialized test equipment is required in order to perform a top-quality calibration.

One caveat: The basic ISF calibration or even ISF Level 2 calibration, even tho it is has become a household word in videophile circles, does not cover everything a projection TV may need. If it is a CRT-based set, there are many image structure elements that need to be mastered as well – like focusing (both electrostatic and optical/mechanical), geometry, convergence, astigmatism and scheimpflug. So if you have a CRT front or rear projection display, getting an ISF calibration will only be a part of what a set might need to get an optimal picture.
