Is it worth the money to have a professional calibrate my HDTV?

Q. As I have asked in my first question, how does one get their HDTV calibrated?

A. No. I took the plunge even tho everyone said it was hard, and used a calibration dvd that Circuit City gives out. Took about 30 -45 minutes including the time for the audio. No big deal.


What is a good brightness level for my LG HDTV when having full-range RGB on in my PS3?
Q. I'm sure all you PS3'ers have seen the RGB settings, so can anyone that has full-range on tell me what their brightness level is on their hdtv when full-range RGB is on?

A. Every TV is different, so a good brightness setting for one TV would rarely be the correct setting for another. And while some TVs might look better with full range RGB, others might do better without it.

If you are concerned about optimizing your system for the most realistic color reproduction and brightness levels, you should buy or rent a tuning DVD or Blu-ray so you can tune the TV using standard test patterns: http://www.amazon.com/s/ref=nb_ssc_1_11?url=search-alias%3Ddvd&field-keywords=calibration+dvd&x=0&y=0&sprefix=calibration .

Regarding RGB range, IGN explained that feature the best: http://gear.ign.com/articles/938/938051p3.html .


How can calibration DVDs help your HDTV if they're standard definition?
Q. I don't understand how these DVDs will help your picture quality if they're standard DVD and you're calibration for an HD picture. And please don't go on about how they have them on Blu-Ray. For a long time they were only on standard DVD and some of those are still being recommended.

A. Do you know why you calibrate?

When you have some image - the electrical signal gets modified by a bunch of things before you see it:

* The quality of the source material
* The output electronics of your source device (Disk player, game system, cable or sat box)
* The type and somewhat the quality of the cables going to your TV
* The input electronics of your TV
* The Brightness, Contrast, Color settings on your TV

When you 'calibrate' - you want to start by shoving a pure-white, pure-red, pure-green color through all that mess so can compensate for everything by adjusting your TV brightness, color and contrast settings.

A standard def DVD is totally capable of giving you white, red, green fields to make basic adjustments. It can also produce grey-bar test patterns and other test patterns to adjust contrast, brightness, etc. Being 480 or 1080 does not matter for these adjustments. Flowing through all YOUR gear and cables is the important part.

You probably do NOT want to use a DVD for the more advanced adjustments like convergence or adjusting the fine-focus on your HDTV. But these settings are usually hidden away in a service menu so that only someone with some training, and the HD version of the test patterns, would use them.

Even putting in a Pixar DVD into your BluRay player, going to the disk setup menu and using the test patterns to do the basic adjustments is much better than leaving a HDTV set to the factory "torch mode".

The BluRay version of Digital Video Essential or the Spears and Munsell disk is better. These run $18-$30 on Amazon and give you more test patterns and tweeks, a green filter to look through, etc. So if you have not bought one of these but want to master the settings in your HDTV, these should be on your shelf. But using a DVD version can still get you to 90-95% of where you want to be.

Hope this helps.
