As a general rule, the consumer based “calibration” things like the THX discs are pretty useless. The consumer level discs from Avia and DVE are OK, but do take some time and effort to accomplish. There’s a private donation-based disc available called “GetGray” that has all the necessary test screens for calibrating either with or without light meters. Most videophiles insist on using light meters, but most anyone can get at least passable results without a meter. Proper brightness and contrast are critical, and effect all other display parameters including picture sharpness and color saturation.
The one thing that’s for certain is that careful calibration is the only way to get the most from a monitor, and out of the box settings are WAY off in most cases. It’s also often best to turn off most of the “auto” contrast and gamma settings that a monitor has, but this is not a hard and fast rule. Just be aware that these type controls may be defeating or affecting your other settings. The default setting for “sharpness” should be off or turned very low, and DNR type controls should be off as well in most cases.
[QUOTE=ricoman;2072312]Remember to adjust the TV in your regular viewing environment and lighting for best results. If you have the lights up bright so you can read the guide and then turn them down for normal viewing, it defeats the whole purpose. [/QUOTE]
Exactly correct, lighting is easily the biggest factor that you have control over. Keep all your setting adjustments small, and re-check all other settings whenever an adjustment is made. Be patient. Brightness effects contrast, color and hue, contrast effects brightness, color and hue, etc, etc.
