Hello- I have one of the early built Denon 3910's that does not pass "below black" and if paired w/a Sony SXRD, does it matter? I could send it to Denon to have the glitch fixed but I have heard that unless the TV it is hooked up to is CRT based that the display will not hold below black anyway. Should I be concerned w/ below black if I am confident I can still calibrate accurately w/ Avia or DVE?

Thanks!!
