I have a rear projection tv that someone suggested I have calibrated. I have heard of software to do it myslef with a PC. The TV is a Toshiba 42H82 is there software (reasonably priced) I can get to do this myself with a pc. Or am I better off having it done by a professional, if so can anyone suggest someone in the Baltimore maryland metro region (harford county) to do the calibration. I tried searching the web and couldn't find anyone.
