Pascal, It would be a disappointment if there was nothing specific about the particular Huey bundled with the XL20. I know *I* would be very disappointed. Why? Everyone I know's understanding about the Huey or the EyeOneDisplayII bundled with the XL series have custom matrix coefficients optimized to correct for the response of the colorimeter. I would be curious to compare my regular Huey's response to an XL20's Huey response on the same monitor. If they would be the same then it would be a disappointment *and* it would mean that anyone is bound to get better readings off the XLs using an EyeOnePro spectral readings. Does that make sense to you? Roger > There is probably nothing XL20 specific about your Huey... The logo is > just > branding...
