Quote - Kawecki - go read something for once. Just once.

Quote - A common misconception is that gamma encoding was developed to compensate for the input–output characteristic of cathode ray tube (CRT) displays.[2] In CRT displays the electron-gun current, and thus light intensity, varies nonlinearly with the applied anode voltage. Altering the input signal by gamma compression can cancel this nonlinearity, such that the output picture has the intended luminance. But in fact, the gamma characteristics of the display device do not play a factor in the gamma encoding of images and video—they need gamma encoding to maximize the visual quality of the signal, regardless of the gamma characteristics of the display device.[1][2] The similarity of CRT physics to the inverse of gamma encoding needed for video transmission was a combination of luck and engineering which simplified the electronics in early television sets.

You are so tiresome it is mind numbing.

If you people do not POUND him into shutting up, I'm leaving.

You continue to post articles from Wikipedia, this help you nothing, because Wikipedia, even it can be useful for referrences, is full of mistakes and written by anyone many time lacking the knowledge on the subject.

In your refference there are two big mistakes:

"varies nonlinearly with the applied anode voltage" It is non-linear with the grid voltage and not the anode. Is the grid voltage that controls the intensity and not the anode that is kept more or less constant at 30,000 Volts

"they need gamma encoding to maximize the visual quality of the signal" Gamma correction has nothing to do visual quality and has no effect on signal to noise ratio. The signal is transmited inverted where the hyper-black levels have the biggest amplitude.

Do you know what is transmited in the TV signal, do you think that is RGB ? and do you know what is gamma corrected ?

Stupidity also evolves!
