Sharpness Knob
IIRC, they started putting this control on higher end TV's in the '80's, and by the '90's all sets had it. What does it do other than introduce noise? It's still being used on LCDs.
A lot of VCRs around this time had this adjustment too. |

I would guess the "peak pix" control label on my '73 Zenith is just an old term for sharpness. I rarely touch that control. I've noticed some DVDs produce a clearer picture than others so some may want to adjust sharpness to compensate.
My Sony Trinitron from '77 (not working anymore, quelle surprise) has a sharpness knob. |

I remember on 1 black and white TV we had it had a 'FINE TUNING' slider....... That made it possible to tune in scrambled signals so it could be watched (It was good enough)

Sharpness controls have been around since the 50's.
" Noise" is mostly on the high freq side of the video. All the control does is cut off some of hi freq video. If you have a perfect signal & TV you can run it full sharpness. If a grainy pix turn it down. You will loose small detail but the pix will be better. The peak pix control is the same on newer Zeniths. Zenith used the control on almost all its sets except the small B&W's. 73 Zeno LFOD ! |

Zenith would delete it on the cheaper models.
