LG: Share Your Custom Display Settings

OK again LOL

I found the 100..90..80.. now, with that I looked up "IRE" in the wikipedia, and have a definition of it, but still not a real understanding of its function.

I assume that all those different settings for each level of the I.R.E. are settings for individual signals?

Here is what Wikipedia defines IRE as:

"An IRE is a unit used in the measurement of composite video signals. Its name is derived from the initials of the Institute of Radio Engineers.

A value of 100 IRE was originally defined to be the range from black to white in a video signal. A value of 0 IRE corresponds to the zero voltage value during the blanking period. The sync pulse is normally 40 IRE below the zero value, so, peak to peak, an all white signal should be equal to 140 IRE.

The reason IRE is a relative measurement (percent) is because a video signal may be any amplitude. This unit is used in the ITU-R BT.470 which defines PAL, NTSC and SECAM."
