Hi All.... I just recently bought and then returned a Hitachi 55VG825 LCD RPTV. I really liked this particular set, but I just couldn't get past what I considered poor black level. I ended up bringing this TV back and exchanging it for a Sony 60" SXRD. I am much happier with this unit, although I did have to pay a premium for it compared to the Hitachi. Anyway, I am looking for info in regards to getting this new unit calibrated. I know that the CRT RPTV's greatly benefit from proper calibrating, but would I see any difference in my new Sony being tweaked? I am very pleased with the picture so far, and don't want to spend additional money if it really isn't necessary. All constructive comments are greatly appreciated.
