What you need to do to your new HDTV:
Here are some hints to get your HDTV in tip-top shape, to get the best possible picture, and to see the movies and shows as the directors intended.
Some people think that proper calibration is only required for CRT-based RPTVs, but don't confuse calibration and convergence. All TVs can benefit from a proper calibration since none of them come from the manufacturer properly set up.
1. There are specific standards on how to set up a TV so that it looks exactly like it should (like the studios and directors intended). It is obvious when you look at a number of TVs displayed in a store that none of them meet this standard - all the TVs look different - colours vary, etc.
2. Your HDTV, as set up by the manufacturer, may not even be close to this reference standard. This is because they set up TVs to look good in brightly-lit stores and to attract your attention. Those settings make the TV much too bright and the colours much too vivid for use at home. We call this "Torch Mode".
3. This "torch mode" can even cause premature failure of your HDTV because the contrast, brightness, colour, etc are all set so high that they can harm/tax your TV. These settings need to be changed.
4. There are several setup DVDs available that can assist you in setting up your new HDTV by yourself. The main three are:
Digital Video Essentials (DVE)
Sound and Vision Home Theater Tune Up (co-developed by Ovation and S&V)
The latter two are the least expensive and have everything you need to set up your HDTV. AVIA has some test patterns that the others do not, intended for the technophiles and professionals. These DVDs are available on-line or from your local electronics stores. You may be able to borrow them from the library, or rent them from Blockbuster. Make sure that the 3 filters are in tha AVIA box and the one, blue filter is in the S&V box.
Some people believe they can simply use the settings from someone else. This is simply not true. Here's why (This is explained again in the videos below):

For people who wish further explanation on why to calibrate and how to calibrate, please see the following links which have two excellent 5 minute videos discussing the basics.
Calibration in detail
5. If you are not technically inclined, you can hire someone, like an ISF technician, to set up your HDTV. He will do even more than is possible with the setup disk. Since you have just spent a fair bit of money for your HDTV, it is not a bad investment to get it properly set up. The cost may be around $3-500. This is called ISF calibration.
6. If you are
going to do the setup yourself, I'd suggest you watch the setup DVD first to get an idea of what needs to be done and then use the DVD later, or on another evening to do the actual setup. You can do this setup as soon as you get the TV home. The TV will change a little over time, so minor touchups may be in order once in a while.
7. Before you do the setup, you need to turn off all of the automatic settings on your TV
, as these typically make the picture worse rather than better. They also hinder the setup process, so you need to turn them off and leave them off. (For example turn off Auto-Colour, Black Level, Perfect Picture, SVM, etc). Most HDTVs also have a "colour temperature" setting. The warmest colour setting is always the closest to the NTSC standard. You must choose the temperature setting FIRST
, and then calibrate, since this setting will affect the tint, colour, etc.
If your DVD player has a "black expansion" or similar, you should typically turn it on.
8. When doing your setup, do it on the "movie or cinema or user or custom" mode (usually the last one in the list of picture modes). Many HDTVs today will remember the calibration for each input.
When you initially get your TV, and are not ready to calibrate yet, chose a mode other than the default Vivid/Dynamic mode. Once you're redy to calibrate, then choose the mode recommended above, if that wasn't the mode you picked.
What about the other inputs on the TV and the other devices connected?
See: Calibration on different inputs
Once you have done all of this, your HDTV will look as it was intended, will last longer and also will provide you with the best possible picture. At first you may not "like" the settings, because they will look "different" from what you have been used to. Give it at least a week and then you will never go back to watching a set in "torch mode" again.
Sometimes the settings may not be exactly to your liking, even after a week. Feel free to tweak the settings a bit by eye. Not all TV channels provide excellent quality images, so you can increase or decrease colour, contrast, brightness or sharpness a few percent either way, so that the set looks good to you. This can be a bit of a compromise between the various channels. For example some channels may look too "red or green" while others look "washed out".
