Most sets are factory preset to look good on a show room floor, where they are competing against many other TV's for your attention. PLus show rooms are not always the same as your living area, for lighting and other factors that can effect how the overall picture looks.
If you are interested in getting the best picture from your investment, at a minimum one of the few calibration discs out there will help you understand what makes a good picture, and how to get your set as close as you can . LCD TV's often are not great in the black level and thus are often not easy to calibrate fully. But you still can make them look better.
Spending the $$$ on someone certified to do this. Alot of technical knowlegde is required to be certified to calibrate TV's. plus there are very expensive pieces of test equipment needed. It takes a fair amount of time to do the job correctly, so yes it's expensive. Is it worth it, thats up to you and what you want from your set.
Hello, I own a 55' HD Sony LCD RPTV, ts the KDFE55a20.
Should I bother with the purchase of a calibration disk?
I cant help but to wonder if its just a rehashing of the THX optimization found on the Star Wars movies or even finding nemo.
Is the disk worthy of the effort or is professional calibration the only way to go? Better yet is professional calibration worth the $$$$$
Remember, its a LCD RPTV.
