There's more than the usual commentary on the merits of the top 2 screens and black levels currently. I'm wondering if Piers and Gordon would be prepared to give some trusted technical comment, not asking for endorsement but just their experiences, as I'm sure they see many panels and TV's in their travels, and it is their livelihood in ensuring they are steup for optimum viewing quality and experience. Here's a few questions :- 1. As part of an ISF calibration how much work goes into setting up blacks or greyscale? Are they really that bad out of the box, and does ISF give significant improvements that just aren't anywhere near possible with user controls? 2. It's well documented that Pioneer have always struggled with black detail up against Panasonic. Is that your experience, and does an ISF-calibrated Panny vs ISF-calibrated Pio still leave significant differences in comparing their black detail response? 3. With the Pio 6th generation offering ISF day and night viewing options, does that mean that lighting and viewing environment have a 'major' effect on Black levels and colour. Surely your technical doohickeys are designed to measure and correct the exact correct settings, or do the doohickeys themselves interact with the lighting and environment? 4. Do you have personal opinions on the Pio vs. Panny debate, or are you of the opinion that it is completely subjective and each to their own?
