Plasma Calibration

by jgoetzel / December 4, 2008 8:04 AM PST

Ok, so I am trying to calibrate my new Panasonic Plasma. I had heard that any blu ray with the THX logo would contain an area to help with this. I rented Indiana Jones (the new one), and can't find any place that seems helpful in this area.

Anyone have any suggestions?

THX optimizer not the same as professional calibration
by Pepe7 / December 4, 2008 11:24 PM PST

The two terms are not always used correctly. Unfortunately, using a THX *optimization* disc doesn't do the same thing as a professional *calibration* since it doesn't get you 'under the hood' into the service menus. Unless you are trained I would not recommend poking around in the service settings. Now THX optimization might be better than the settings you can achieve manually with your naked eye, but you might look at an HDTV in person that has been professionally calibrated to see the difference. That will be at least couple hundred dollars though. You could also *rent* a DVE or AVIA disc to see if one of those performs any better than the THX method. From Gizmodo for reference-

good luck and please post back your results when you get a chance.

forget the professional calibration ,its not needed plus it will made your tv very dim. its only for people with too much money to notice some is gone or those anal types who watch their tv's in the dark.

It will look too dim, if you calibrate it at night, and then watch during the day, on the same setting.

A good ISF calibration will get you specific settings for EVERY source you have, whether cable, dvd, bluray, etc, AND multiple settings between day and night for any particular source.

Well, I know someone who did that with his own Pioneer. Im sure other brands will have less settings or flexibility in doing so.

And some TVs are so bad anyways perhaps, that its worth it. But, I still think its a bit of an over-generalization to claim that people would be considered anal to watch in the dark.

What, do you prefer that movie theaters had skylights?

as a subsciber to many audio-video mags including the super snob mag "stereophile", i can definitely say there are anal types in every aspect of both areas. listen, i have owned and still own stereophile recommended amps, preamps, speakers, cables, etc. Guess what? side by side they may sound different(better?), butwithout side by side comparisons they all sound pretty much the same. the point is, with or without a professional calibration they all look pretty much the same if you dont have them sise by side! well so it goes, like all the "recommmended component" to the basement. i now use a pioneer receiver(big one though) to unclutter my life. cheers

It must be nice going through life with the blinders on. LOL.

The HDTV only looks dark to you because you aren't accustomed to a more accurate PQ, or possibly, you actually prefer the less than ideal 'torch mode' of the big box retailers. Heck, I suppose you're entitled to an opinion, but nobody's *mandating* spending the extra cash on calibration in this thread, it's just an option being discussed. And in case you haven't figured it out yet, a dark location isn't required to gain some benefit from going through a professional calibration. Even my 'non-geek, non-videophile' friends (ROTFL, using your logic) noticed the difference in PQ when I took them to a specialty store with the same plasma panel they saw in another location, but professionally calibrated. Their only complaint was that they weren't made aware of such a possibility by the installer who came to their house the previous year. I did receive one compliment from a friend who commented he wasn't aware the green color of the NFL grass could get any more realistic than after the calibrator left his family room ;).

THX calibration

That was me who suggested using a DVD with the THX calibration setup. No, it's not the same as using a "Professional Calibration Disc" (which I also have), but for good initial setup, the THX calibration is great, especially since most people try to setup their TVs using their eyeballs. If you do use the THX calibration, then use a small piece of blue gel (clear blue plastic sheet) as this will be essential to calibrating more exact colors. I've used the THX setup on my TVs and for a quick semi-professional way of doing things, it works wonderfully, especially since many DVDs come with this setup and you don't need to pay another $40 for a setup disc. Until someone else here uses the THX setup and can claim differently, I personally recommend it.
