There are a number of questions that pop up from new owners so I'll try and list them here as time permits"What are "calibrated settings"? NOTE: See bottom of this post for a TV tweaking guide.
Calibrated settings for this line of LG TVs refers to using the ISF Expert1 & Expert2 Picture settings in the TV Menu. The TV also comes with "preset" Picture modes of Vivid, Standard, Cinema, Sport , and Game. While these last Picture Modes have limited user adjustments, the ISF Expert modes have a wider range of options and adjustments to picture color, detail, and quality. Calibration usually refers to using external equipment and test media to set the TV gray scale and color temperature as close to 6500K natural color temperature as possible. By doing this and setting other picture controls such as the Backlight, Contrast,Brightness, and Color within a certain range of settings; the best possible picture can be produced by the TV. Since a calibration really needs to be done on each owners TV for the best benefit, settings provided in this thread serve largely as a baseline and can usually
improve picture quality compared to the "preset" settings. The settings listed in Post #1 also include a "range" of user adjustment to account for room lighting, differences in exact TV model and screen size, and personal taste. Your TV performance may vary when using the posted calibrated settings. Calibration pertains to doing it with the a particular TV and the equipment connected to it. There is now even a question of how valid a calibration may be since many use a computer, light sensor, and software to do it; while in actual use, a TV is used with it's built in tuner, DVD/Blu-ray player, cable or satellite set top box, game system, or Home Theater PC.
Nevertheless, usually calibrating the gray scale of the TV results in marked improvement in picture quality even if it is just close to the 6500K target. So overall, even using baseline settings from a calibration arrived at by another TV owner and equipment; can be beneficial.What is a "bias " light?
A "bias" light placed behind the TV, is just a low wattage lamp that provides diffused, indirect light to the area around the TV and the wall/ceiling behind it. Usually you can use a small stick lamp, clamp-on utility lamp from a building supply store, or even rope lights fastened to the rear edge of the TV frame. A 13 watt compact florescent lamp works well, and use a warm white bulb in the 5500K to 6500K region. The color temperature of most CFL bulbs is marked on the package.
Also, it is important to keep other room lighting from shinning directly in the screen or into the sides of your eyes. For best viewing ,any lights should be well off to the sides and and aimed/reflected off the walls and ceiling providing a soft, diffused lighting for the room.How Do I "Calibrate" my TV?
The only way to truly calibrate your TV is to use professional or maybe consumer grade calibration equipment. However, there are aids available to help you get the best picture quality out of your TV. One of the best is AVS HD709 that can be downloaded here
If you are savvy with regard to downloading and burning ISO files this is a great aid. Even if you aren't try following the instructions and you will be rewarded!
However, if you wish to just use your eyes and some media you can also use the THX picture adjustment utility on some Disney and other Blu-ray or DVD movies. Basically, you want to keep the LCD panel back light low or mid range, color mid range, Contrast in the 80% range, Brightness in the 50 to 55% range, Color at 50% plus or minus 3, and Tint at zero ( No Tint).
Then you can use a "reference movie" such as Sea Biscuit for making fine tweaks. I am including a guide that also tells why this movie works so well as a near "calibration aid". Give it a try and see if your new TV shines!* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *For those who may be interested in using Sea Biscuit (you don't have to like the movie & it is very inexpensive) as a follow up reference DVD or Blu-ray after calibration or using a set up media such as AVS HD 709, here is a summary of what to look for using this movie. This movie was particularly well made and has natural as well as very vibrant colors. It also contains many B&W stills that are great to check gray scale. I believe it serves as a "real world" follow up to verify if your TV is displaying all it can in terms of picture detail, color accuracy and level, as well as help in possibly some fine tuning.
I have found that if a movie like Sea Biscuit is displayed properly on a TV that any movie will looks it's best. Owners may be surprised at what Sea Biscuit reveals about the time they put into a calibration or using other "tweaking" aids.Try This Guide Using The Movie. . .Sea Biscuit
