I know people have posted the DIY tv calibration website but I can't find it. Will someone please post the link again. Thanks!

Check out this Home Theater Magazine link for their HDTV reviews and the settings that they've ended up with for DOZENS they've reviewed: www.hometheater.com/category/flat-panel-reviewsI've found these setting even better than Tweak TV's (that's assuming HTM's reviewed the TV you're calibrating of course! - worth a search through the list though...). |

Many think these settings on these calibration sites are the be all, end all settings that a particular flat panel should be set. Sure they may end up close, but everyone's lighting environment is different, so different levels of the many different settings when properly calibrated by an ISF professional will definitely vary, and this isn't taking into account the aging of a panel and it's phosphors especially the first 300 hours or so.

You're right of course about the superior benefits of professional HDTV calibration - but I don't think anyone here has said these ready made settings to be found on the web "...are the be all, and end all settings'!  Good that you also pointed out that an HDTV should be allowed to 'age' a bit before calibration 0 especially plasmas - due to phosphor age, etc. Because if calibrated too soon, then they'll find themselves re-doing it again soon... |

I have *never* read where anyone posted a sentiment like that. The fact is that using these settings will get you to about 80-85% of the "goodness" of a pro ISF calibration. And I'm betting that for *most* folks here, that would be plenty good enough - especially considering the price...

And I'm betting that for *most* folks here, that would be plenty good enough - especially considering the price... -RW- Yes I do agree that many will be satisfied with that 80% figure you've thrown out there. I'll say that everyone's perceptions of what other flat panel owners on other sites state are inevitably going to differ to some degree. I've also read on many a site about flat panel owners of particular sets and how blindly those that are using the results from someones ISF calibration in a particular type of enviroment. The particular settings are for that particular lighting environment in which that particular flat panel is in. Yes you may get pretty good results and you may not, but I've actually been present and have seen the difference from actually seeing a panel in which a friend used posted settings from a a particular forum and the results of that same panel after an ISF calibrationist professionally calibrated it. In this case, seeing was believing, as well as the before and after graphs/numbers that were provided. I was actually floored to see how under utilized the panels black and white content was being used, and this is because the original settings that my friend was using, was from the same brand/model that had been calibrated in a completely different lighted environment. I'm not saying not to use those settings that are available from sites such as TweakTV, CNET, HighDefJunkies, AVS, HDForum, PlasmaTVBuyingGuide, etc.,etc.,etc., as they are most likely better than what the default settings are from the manufacturer. I do however assure you that having an ISF calibration performed in your own home theater will more times than not, be a night and day difference.  As far as price is concerned, I've seen many a owner of Panasonics or Samsungs upper level plasmas panels, spend upward of $3000-$3400, so what is another $400 for that panel to be properly calibrated. Remember, the odds are you'll be watching that set for several years. Again, this is just one persons opinion and as many here have said before, "your mileage may vary". Where someone else doesn't believe it to be worth it, I just happen to believe it is. |

Just so we're clear, I said "Many" and that wasn't referring to any member here on the Lounge at all. I've been reading up on many of the sites I listed in my last post, and it is amazing how many members on those sites just want the results from a calibration performed elsewhere to blindly use for their completely different environment, instead of buying their own calibration disc, ie: WOW, DVE, Spear & Munsil, etc., etc. or actually having a professional come perform an ISF calibration. |

If I may, while fantastic, discs like WOW or DVE (Digital Video Essentials) do not equate to calibration but rather fine image adjustment. Actual display calibration can only be carried out to its fullest extent via specialized tools and properly tuned software and meters. Discs are better than factory settings, but are not the same as a true, professional calibration.
Sorry, I don't mean to drink anyone's kool-aid, but calibration is something I take very seriously as some of my best friends in the industry are professional calibrators and I see what type of uphill battles they face with consumers.

Never under any circumstances use another man's settings for your own. Calibration simply doesn't work like that. You can't even use your own and apply them to the same make and model display elsewhere in your home. Please don't help spread misinformation, hire a professional if absolute video acuity is what you're after. Sites that promote the sharing of settings are truly doing more harm than good.

Andrew, I couldn't agree more. There is no substitute for an actual ISF calibration specialist. |

Respectfully, and nothing against any ISF fans or personnel here on the site, but I prefer THX's methodology though both ISF and THX endeavor to the same end result -SMPTE standards.

Nice thing about standards - there's plenty to choose from!   LOL! .. |

Can you share some more info as to the differences? Knowing you are in the film industry, it would be fascinating to get a professional view on this. Especially since the end result should be close to the same. |

When I bought my HD LCD from Best Buy, they tried to get me to use their Geek Squad guys to come and calibrate it. Not something I had a lot of confidence in to say the least.
I have an AV buddy who told me about the ISF calibration and he hooked me up with a guy who came to my house and did the whole deal for a great price.
It was great seeing the pre and post results that were printed out showing the major differences in the "Factory Floor display " settings and the end results in my house. I have since referred this guy to a couple of my friends who are also very happy with the difference in the picture quality and balance.

The THX program was written by former members of the ISF (some who really helped found the program). They branched off of ISF because they had wanted ISF to go down a different road -one that used more sophisticated tools, required more hands-on time rather than just lecture a la ISF and who's members had to get re-certified regularly. They also wanted the program to have an educational component, whereby the calibrator was trained in and responsible for making sure the customer understood why calibration was necessary as well as what was happening to their beloved displays during the process.
ISF wasn't interested in this approach so a few key members broke off and approached THX who happily (as the story goes) took up the charge. You can become ISF certified by attending one or two lectures where another fellow ISF calibrator typically talks to you about the business of calibration and then shows you the process on a power point etc. There is very little hands-on time -at least in the first two or three levels. With THX it's all classroom and hands on. Classes are not lecture and they're smaller. Would be calibrators sit two to a display and calibrate until they're blue in the face. Then they're tested on a device in front of the class and instructors, versus just taking a written test.
THX's mandated gear for calibration is more highly regulated as are their members. Once out in the field, both (largely) adhere to the same set of standard(s), which is SMPTE. A few of the standards within SMPTE have a range -i.e. brightness -which ISF is okay with hitting any value within said range whereas THX sets a target that is typically right in the middle. For example; brightness for a front projection system is (off the top of my head) is 12 -16 foot lamberts at the screen (I may be off by one or two); with ISF you can calibrate to 12 or 13 on up to 16, with THX you must hit 14 -or the middle value. It's not that the THX method produces a "better" image than ISF -I just trust their methods and believe that their members have a better grasp out of the gate than those who attend Level 1 or 2 of ISF training.
Just my 2 cents. Regardless, both programs should improve your image quality and are better than a) doing nothing or b) calibrating via a disc and your own two eyes, which isn't calibration.
