Unit-to-unit sample variations, the viewing environment, and the source might render these recommendations less than optimum. They are provided only as a potentially useful starting place.

The settings here that are most likely to translate reliably from one sample to another are those involving specific features with only a few selections, such as Gamma and Noise Reduction. The ones most likely to be subject to sample variations are video controls offering a wide range of adjustment, such as white balance (grayscale) and color management (where available). Even relatively small differences in the common control settings, such as Contrast, Brightness, and Gamma, can shift the white balance, though the resulting visible change may be innocuous. Production line tolerances can do the same.

We do not provide settings or access codes for service menus. Random alterations of such controls without detailed knowledge of what they do may corrupt a set's firmware. This will likely require extensive in-shop repairs not covered under the warrantee. Service menu calibrations should be attempted only by an experienced calibrator familiar with the specific brand of set, and a clear understanding of which controls to use and which to avoid. We strongly recommend that you find the optimum basic video settings for your sample by using one of the many available display setup DVDs, such as Digital Video Essentials (DVD) or DVE HD Basics (Blu-ray). These will help you to set the basic controls correctly, brightness, contrast, sharpness, and sometimes color and tint. Experimenting with the more complex color calibration and other controls in the user menus will do no harm; the changes may be easily reset. But tuning a set "by eye" is no substitute for a full calibration, which is best left to a trained and properly equipped technician such as those certified by the Imaging Science Foundation (ISF) or THX.
