A couple of answer, maybe others can help fill in the gaps... 1. Not sure, but GaryB might be able to help. Probably not an issue on a new unit though? 2. Yes I believe you should notice a difference between MPC settings. Another owner commented similar and I think he may have returned his unit. 3. The fine tuning of convergence will lose resolution as it is done my scaling unlike the 1 pixel steps of the cheaper models. I've never really been convinced that it is worth doing and why they put it on the dearer models, perhaps someone else could give a good arguement for, but I can't: Personally I would leave it 'OFF' and just use the single pixel steps if you feel it gives a better result than default (though my HD350 can't be improved by moving as it just causes an issue in another direction, so default is best in my case). 4. Ideally you should measure the colour gamuts to see which one gives the closest to rec709. I can't remember off hand, but standard as you say seems to be a larger gamut, so would be oversaturated. However, if using an external CMS or the one in the projector in your case, then you have to start with oversaturation as the CMS can only reduce and can't add any saturation. If you are just using it pre calibration, then the THX mode should give something approaching rec709 (possibly slightly undersaturated, so chose your poison). 5. AVS HD709 is great for setting the basic brightness and contrast settings: I use it myself as part of a pre calibration set up. However, IMHO you can't really adjust the colour or tint without tools, as the coloured filters included with some test discs aren't very accurate anyway. FWIW I'd just leave them at 0. If you want equipment, then I'd highly recommend getting Chromapure and an i1 Display Pro sensor, but then this will cost around the same as your Pro calibration, so it's not a trivial commitment.
