Home I've been calibrating HDTV's for over a decade. Frankly, my work has gotten easier with the manufacturers of todays displays following the lead of the Imaging Science Foundation.If you wish to see what the artist intended in todays films, you can come very close just using the film mode presets in many of todays top tier displays.On the other hand, if measurable accuracy is your goal, an ISF Calibration will guarantee your display is producing the best calibrated images possible!

The Art in HDTV

Big Screen results from your Home Theater!

About

Since 2002, I have calibrated hundreds of displays from studio production monitors to state fo the art Home Theaters.My desire has always been to eke out every iota of performance from HT gear. When the Imaging Science Foundation and a small core group of HT enthusiasts began to see the future of what was to become HD, I was pounding on their doors. I learned and practised on my own gear, bought the testing probes and programs required, and went to it. Gads, what fun! A hobby that actually paid for itself....almost.

The Basics

Proper 10 Step (Basic) HDTV Calibration workflow:Tools Required: TV and DVD or BD Player. Equipment Owner’s Manuals. A test pattern disk. Blue and if possible a Red filter. An hour or two.1. Check for correct connection interfaces between components.2. Check that sources are set for proper resolution output considering the TV displays capabilities (480i, 720p, 1080i or 1080p). Check that all enhancement protocols such as “black enhancement” “room (ambient) lighting control”, digital noise reduction, etc.etc, are all in the off or defeated mode. This needs to be done on the TV as well as the DVD player and possibly in your Av pre/pro or receiver. We want to calibrate just the display initially.3. Allow a few minutes of warm up time for any display type. It used to take 30 minutes. Today, perhaps 5 or 10 are adequate.4. Using any pluge pattern (black bars or blacker than black bar pattern) from any test disk or signal generator, set up the black levels using the brightness control.5. Using a ten step crossed gray scale pattern or facsimile, adjust the white level with the picture/contrast control so clear delineation can be seen between the 90 and 100 IRE boxes. If you are blinded by the light output and can still see delineation, reduce the white output to help with eyestrain.6. Recheck the black level and readjust as required. Black and white level controls tend to interact. Spend all required time to get these two levels precisely set.7. Set color and tint with the aid of a SMPTE blue bar pattern and with the aid of a blue filter. These controls (color or Saturation and tint or Phase) will also interact to some degree with nearly all displays. Recheck and readjust as required.Note: I like to use a red bar pattern with a red filter if I will not be making other possible corrections with test probes and gear. This red pattern test will help most basic calibrations remove the over saturation of red due to high presets internally designated by manufacturers with regards to color temperature. Using the red pattern will compensate for those displays that are running a cooler than standard color temperature. This is done to help sell TV’s off the showroom floor. The by-product of which is that what should be a correct blue bar setting tends to over-saturate red, thus making skin appear to be redder than normal. If a red filter is not available to you, simply reduce the color setting until skin tone appears more accurate.8. Check that the Sharpness pattern shows little or no ringing or what appears to be a white line next to the black lines of the pattern. On today’s displays the sharpness control may not appear to make much of a change. Just make sure the control does not seem to add the above mentioned white lines next to the black ones.9. If the display has a Cinema, THX or Movie/Film preset and the room in which you will do critical film or TV viewing has low ambient light levels, use that preset. You will still need to verify that you are getting the best Black and White levels possible by following the above procedure. At this time and in the low light levels of the room, check for a “Gamma” preset and if present, adjust it to 2.4. Again, recheck the B/W levels as the Gamma control found on some displays will assuredly affect the B/W level range. Also check that the color and tint of the image is acceptable.10. Most importantly, have some fun with this and remember to enjoy a film or 2000.By following the 10 steps above, your TV will produce excellent pictures that come very close to what the director of the production intended for you to see. There are further steps to be made that will derive even better quality viewing of your media, but just performing the above will get you much closer than those souls that just plug it in to the AC and a box.
Anyone can/should do a couple of things to their new display. Follow the simple procedure on the right and much better images are possible.If you feel that you'd rather have me perform a "basic calibration", I'd be happy to do so.
Services A Basic Calibration covers those steps that any consumer can do with the aid of a few basic test patterns and the remote supplied with a dvd player and display.Full Calibrations include all of the protocols of a basic calibration and in addition will provide the viewer with as close to the actual media content as conditions and equipment permit. It will include measurement with specialized tools and probes. Any errors found will be corrected to the best of the displays ability to do so. Areas measured and adjusted .1. Gray Scale2.
