those are 50% as likely to make the picture worse than better.
again people are clueless as to what calibration is and how it is specific not only to the TV as every one is built different but the room as well.
You could always buy a calibrator and learn how to do it but I imagine that would take days if not weeks to get it absolutely right
Yeah that's what you are paying for their expertise. A day and night setting and per device.
The people that think they can just cooy settings off the net don't have a clue.
I have a pc monitor calibrator I'm seriously thinking of getting a TV calibrator now.
I'd rather buy the gear and do it myself. That way I can charge people I know for it too to pay for the gear.
It's why I bought the monitor calibrator.
I already had offers in the past from Vincent from Hdtvtest.
Hisn't.
People have different ocular perception too as all eyes are different. While I have nothing against professional calibration there is an element of emperor's new clothes about it being something magical for your screen. People who get it done are really just after piece of mind and are always keen to bring it up that they spent the money getting it done, but in most circumstances it shouldn't be needed and is a waste of money.
The C9s are apparently okay out of the box in certain picture modes, the B9s however are awful but benefit massively from a calibration.
As has been said, it's peace of mind more than anything to know that you're getting an image displayed the way it's meant to look. If you have dodgy eyesight or don't always use the best source to watch stuff then I wouldn't bother.
I calibrate all my displays using test patterns and my own eyes.
