I’ve never understood copying someone else’s calibration settings (which seems to be very common on A/V forums and groups). It doesn’t account for the variance from set to set, even if they’re the same exact model. And it completely ignores the fact that each tv is in a unique environment with its own lighting.
If it’s the same model, you’ll get in the right ballpark. And the point is to calibrate the panel… not the “unique environment.” A room with the lights dimmed down shouldn’t be much different from another room with the lights dimmed down. And if you have something in your room that’s crazy enough to affect the image on your TV that drastically, then you should probably fix that thing and not adjust the display to counteract it…
