It's the 360 that generally outputs an incorrect picture... the 360's gamma for games is generally wrong. The PS3 outputs everything as it should, assuming everything is set correctly. That's why a lot of 360 games have crushed blacks and overblown whites. Sure it looks punchy and vibrant, but it's wrong.

Believe whatever you want to believe. But FWIW, I do have measuring equipment (i1Display Pro / i1 Display 3) that's considered better than what Bestbuy used for your calibration (Chroma 5). To calibrate a display, you essentially need three things: 1. a measuring device (colorimeter, spectrometer) 2. test patterns (calibration disc or pattern generator) and 3. calibration software (CalMAN, Chromapure, HCFR). You don't need ISF or THX certification to own the equipment professionals use. I'm not THX or ISF certified, but I have been calibrating for a few years now. And on the topic of equipment, professionals (and even many DIY calibrators) have higher quality equipment than what BB GS typically uses (which again is the Chroma 5) There are some DIY calibrators that are more capable than BB's GeekSquad (generally speaking as GS calibrations vary in quality).
The only controls the ST50 has in the service menu are the GAINS and CUTS, which are essentially the same as W/B High and W/B Low in the Pro settings menu in Custom mode. The purpose of these settings are to balance Red, Green and Blue so that your set is displaying white correctly (D65 for REC.709) which is why it's appropriately called White Balance. Custom mode actually has more control over the picture than Cinema mode does, because Custom mode has a gamma slider whereas Cinema mode has essentially no control over the gamma.
Look at the link I posted above. I was able to calibrate my ST50 to dEuv 1.5 (grayscale) and dE94 1.3 (color gamut) in Custom mode. Delta E u'v' and Delta E 94 are commonly used error reporting formulas used for grayscale and color gamut calibration... the lower the number the better. Typically you aim to get dE under 2-3. Compare those numbers to your GS calibration and tell me again that a good calibration can't be done in the user menu. For reference, the numbers you posted above have an avg dEuv of ~7.96, which is why I said that those numbers are most likely pre-calibration measurements.
Look, I'm not judging the quality of your calibration so I don't know why you're being so defensive. Seeing as how your calibrator was there for ~3 hours, he was probably better than most GS calibrators. I'm just stating the fact
that a perfectly good calibration can be done in the user menu on the ST50 (and many sets these days) because all of the available controls are in the user menu.Edited by rahzel - 3/10/13 at 5:23pm
