We often get asked for calibrated settings at HDTVtest.
We're usually happy to share them, especially if a model has a particularly bad out of the box preset mode, so users can see some improvement.
However, even in the case of TVs with decent presets, people still ask us for the settings, so we release them with this disclaimer:The usual disclaimer: Copying calibrated settings from the internet will not net you a calibrated TV. Calibration is an exact process which involves measuring colours and brightness from the TV screen and making precise adjustments to offset errors. In comparison, copying settings used on another TV will only provide an approximate result. In the case of TVs which have very good preset picture modes, they may even make the image quality worse.
Although many settings operate in the same way from unit to unit, some of the most crucial settings - the Greyscale (White Balance) adjustments - are largely specific to each TV and can only be successfully adjusted with a calibration device and software. The following settings reflect the adjustments that we made on our individual review sample.
Today I bought a Panasonic ST50 and as an experiment, copied the settings I used on the review sample TV to get near-perfect Greyscale tracking.
Here is the default True Cinema mode settings on that TV:
And here are the calibrated settings from one TV copied into another:
As you can see, we just took a plus-green TV and made it... plus-red! Delta errors, for the most part, are worse. Colour is reigned in a bit but is still wrong.

here's another example with the out of the box settings on a Samsung LED LCD TV, with the calibrated settings we were asked to give out, copied into a very similar model.
Out of the box:
Copied settings - even bigger errors:
For this reason, we generally only recommend sharing settings if the out of the box preset on your display is especially inaccurate (we share full settings in these cases).If you want the best performance from your display, it needs to be calibrated.
